Description

  The present invention relates to a sorption type cooling device using a low-temperature heat source such as solar heat and a heat switching device suitably used for this device. This sorption type cooling device is also used for heating.

Conventional compressor cooling systems used in buildings, factories, schools, greenhouses, pools, automobiles, etc. constitute a major cause of carbon dioxide emissions. For example, a sorption system that alternately sorbs a sorbate composed of water vapor and releases a sorbate that absorbs the sorbate by cooling the sorbent by releasing a sorbate by sorbing a sorbent composed of zeolite (sorbent), for example. Cooling devices are well known. The batch operation type sorption type cooling device is formed by connecting a first container for storing a sorbent and a second container for storing a sorbate through a communication pipe portion. In the discharge cycle, sorbate is accumulated in the second container by heating the first container and cooling the second container. In the sorption cycle, the first container is cooled and the second container absorbs heat, for example to cool room air. Cold heat is intermittently produced by alternately performing the discharge cycle and the sorption cycle. Solar heat, automobile exhaust heat, or the like is used as the low-temperature heat source.
Since the conventional sorption type cooling device described above is essentially batch (intermittent) operation, the heat of the heating source (for example, solar collector) and the heat radiation source (for example, the atmosphere) and the first container according to the switching of the cycle. It is necessary to switch between the transfer and the heat transfer between the heat radiation source and the heat absorption source (for example, room air) and the second container. Since heat transfer between the first container and the second container and these heat sources is generally performed by a fluid such as water or air, the switching of the heat transfer is generally performed by switching the fluid passage.

Using an air stream as the heat transfer fluid results in a simplified device structure. However, since the heat transfer performance between the air and the solid is small, when air is used as the heat transfer fluid, the first container and the second container are a cooling fin type indirect heat exchange device having a large mass and a complicated structure. It is necessary to have. In the batch system, it is necessary to change the temperature of the large-mass indirect heat exchange device with cycle switching. This means that a large cold heat generation efficiency is lowered due to a large sensible heat loss (mass × specific heat × temperature difference) generated at each cycle switching. In other words, the conventional batch sorption type cooling device is a process that is very wasteful in terms of energy efficiency. This fact suggests that energy efficiency can be improved by reducing as much as possible the mass of the member of the sorption type cooling device other than sorbent and sorbate whose temperature is changed by batch operation.
Water as a heat transfer fluid has an advantage that the amount of heat transfer per flow rate is larger than that of an air flow, and thus has an advantage that the indirect heat exchange surface between the first cylinder part and the second cylinder part can be reduced. The heat exchange with the outside air or the room air is necessary, and freezing, water leakage and replenishment become problems. By using a known heat pipe for heat transfer, fluid drive power can be omitted. However, heat pipes are unsuitable for this type of batch operation because the amount of heat transfer cannot be controlled. That is, for switching between heat exchange between one of the heating source and the heat radiation source and the first container (sorbent), and switching between heat exchange between the heat radiation source and the heat absorption source and the second container (solvate). It is difficult to use a heat pipe.
Further, when an air flow is used as the heat transfer fluid, a motor fan, a damper and a duct are required, and when water is used as the heat transfer fluid, a motor pump and a motor valve are required. In a sorption type cooling apparatus that operates in a batch mode, a heating fluid, two cooling fluids, and an endothermic fluid flow, so that these piping structures become very complicated, and the above-described sensible heat loss further increases.

Patent Document 1 discloses a hot module with a built-in sorbent that is intermittently heated by solar heat, a condenser that condenses high-pressure water vapor from the hot module, and an expander that adiabatically expands and cools the water that has come out of the condenser. Proposed a batch operation sorption type cooling system consisting of a cum cooler, a cold module with built-in sorbent that sorbs low-pressure steam from the expander and cooler, and multiple valves to enable intermittent operation. ing. However, the above-described conventional apparatus of Patent Document 1 does not solve the problem of the batch operation sorption type cooling apparatus. Furthermore, since this apparatus has a long low-pressure pipe through which water vapor as a sorbate flows and many joints and valves, there is a problem that it is difficult to prevent air from entering from the outside. The air that has entered the inside significantly reduces the performance of SUNCOOLER.
Further, considering that this sorption type cooling device is used for heating, a complicated fluid circuit configuration such as a damper or a valve is required, and heat loss is expected to be large. Further, when heat is transported from the solar collector on the roof to the sorption type cooling device installed on the ground, there is a problem that the heat transport device becomes complicated and expensive.

(Object of invention)
The present invention has been made in view of this problem, and realizes a batch operation sorption type cooling device having a simple structure, improved energy efficiency, simplified configuration, and reduced manufacturing cost. Objective. Another object of the present invention is to provide a heat switching device capable of switching between hot and cold with a simple configuration.

(Summary of the Invention)
The sorption-type cooling device of the present invention that achieves the above object includes a first cylinder portion containing a sorbent for desorbing a sorbate by alternately repeated heating and heat dissipation, and condensation of sorbate by alternately repeating heat dissipation and heat absorption. A sealed tube having a second tube portion for vaporization, a communication tube portion communicating the two tube portions, a heating member for heating the first tube portion by heat transfer from the outside, and the first A heat transfer device comprising: a cooling member that alternately dissipates heat of the tube portion and the second tube portion to the outside by heat transfer; and a heat absorption member that supplies external heat to the second tube portion by heat transfer; and the sealed tube Is moved relative to the heat transfer device so that the first tube portion is separated from the cooling member and brought into contact with the heating member, and the second tube portion is separated from the heat absorbing member and the cooling member is moved. Desorption movement to contact And a sorption operation in which the first cylinder part is separated from the heating member and brought into contact with the cooling member, and the second cylinder part is separated from the cooling member and brought into contact with the heat absorbing member. And a drive mechanism.

In other words, the present invention relates to a sealed tube in which a first tube portion that accommodates a sorbent and a second tube portion that accommodates a sorbate are connected by a communication tube portion. The heat dissipation and the heat absorption are performed by bringing the heating member, the cooling member, and the heat absorption member into contact with or away from the first and second tube portions. In this way, the temperature change due to the batch operation is limited to only the first cylinder part and the second cylinder part that accommodate the sorbent and sorbate, and therefore heat exchange between the first cylinder part and the second cylinder part and the outside is possible. Therefore, no temperature change of the heat exchange mechanism is required. For this reason, the sensible heat loss by batch operation | movement can be reduced significantly and thermal energy efficiency can be improved significantly. Furthermore, since wasteful heat transfer due to the sensible heat loss can be reduced, the apparatus can be made compact. In addition, although this apparatus is used for cooling, for example, heating can also be performed by transmitting thermal energy from the heating member or the cooling member to the room gas.
In addition, the heat transfer between the solid and the gas or liquid causes a large thermal energy loss in this kind of low temperature drop temperature swing device due to thermal resistance and temperature loss due to the so-called boundary layer. Since heat transfer is adopted, heat energy loss is small and the heat transfer mechanism can be made compact. In the apparatus of the present invention, the heating member can be constantly heated, the cooling member can be always cooled, and the endothermic member can always be kept at a low temperature. In other words, the temperature change of these members is very small. The cooling member and the heat absorbing member can be moved in contact with a heat transfer fluid such as air or water, and can also be connected to a heat source or an indirect heat exchanger through a heat pipe. Eventually, according to the present invention, it is possible to realize a batch operation sorption type cooling apparatus that has a simple structure, can improve energy efficiency, can be simplified in configuration, and can be manufactured at a reduced cost. In addition, the contact surface of the heating member, the cooling member, and the heat absorbing member, and the first tube portion and the second tube portion can secure a necessary area with a compact volume by providing irregularities in the shape of the contact surface. it can.

The heat absorbing member is reciprocally moved relative to the first tube portion and the second tube portion. That is, in this aspect, the heat transfer device (the heating member, the cooling member, and the cooling member) may be reciprocated by a small distance with respect to the first tube portion and the second tube portion, thereby simplifying the drive mechanism. Energy required for relative movement can be reduced.
In a preferred aspect, the first tube portion and the second tube portion are arranged close to each other, and the cooling member that radiates heat from the first tube portion is between the first tube portion and the first tube portion. It serves as the cooling member which is arranged in and dissipates heat from the second cylinder part. If it does in this way, a cooling member will contact alternately the 1st cylinder part and the 2nd cylinder part which were arranged near. If it does in this way, the 1st cylinder part and the 2nd cylinder part can be cooled by heat transfer with one cooling member.

In a preferred aspect, the heating member is disposed on the opposite side of the cooling member with the first tube portion interposed therebetween, and the heat absorbing member is disposed on the opposite side of the cooling member with the second tube portion interposed therebetween. The In this way, the apparatus can be realized in a compact manner.
In a preferred embodiment, the heat transfer device is configured to be in contact with the first heat transfer member set of the heating member, the cooling member, and the heat absorption member that can contact the first sealed tube, and the second sealed tube. A second heat transfer member set of a heating member, a cooling member, and a heat absorbing member, and the drive mechanism includes the desorption operation of the first sealed tube and the sorption of the second sealed tube. The operation is performed substantially simultaneously, and the sorption operation of the first sealed tube and the desorption operation of the second sealed tube are performed substantially simultaneously. In this way, the cooling operation can be performed substantially continuously.
In a preferred aspect, the two second cylindrical portions are arranged close to each other, and the heat absorbing members of the first heat transfer member set are separated from each other by a distance at which they cannot simultaneously contact the two second cylindrical portions. And disposed between the two second tube portions, and also serves as the heat absorbing member of the second heat transfer member set. If it does in this way, an endothermic member will contact alternately the 1st cylinder part and the 2nd cylinder part which were arranged near. If it does in this way, since the 1st cylinder part and the 2nd cylinder part can cool one heat absorption member, an apparatus can be realized compactly.

In a preferred embodiment, the two second tube portions are arranged in parallel, and the heat absorbing member reciprocates relative to the two second tube portions in a direction perpendicular to the longitudinal direction of the two second tube portions. . In this way, the drive mechanism can be simplified and the apparatus can be made compact.
In a preferred embodiment, the heating member, the cooling member, and the heat absorbing member are configured by a metal member having a concave surface that can be in close contact with the outer peripheral surfaces of the first cylindrical portion and the second cylindrical portion. As a result, the pressure resistance of the first cylinder part and the second cylinder part can be strengthened, so that the thickness of the cylinders of the first cylinder part and the second cylinder part can be reduced to reduce the sensible heat loss. it can.
In a preferred embodiment, the heating member, the cooling member, and the heat absorbing member are formed to have substantially the same diameter as the outer peripheral surfaces of the cylindrical first tube portion and the second tube portion, and the first tube portion and the second tube portion. It has a cylindrical surface that is in close contact with the outer peripheral surface. Thereby, since the 1st cylinder part and the 2nd cylinder part can be made into a cylinder with a big pressure | voltage resistance, the thickness of the cylinder of a 1st cylinder part and a 2nd cylinder part is reduced, and the sensible heat loss (can constitution) Amount × can specific heat × temperature difference) can be reduced.

In a preferred aspect, the first tube portion and the second tube portion are arranged in parallel, and the drive mechanism relatively rotates the heat transfer device in a direction perpendicular to the longitudinal direction of the first tube portion and the second tube portion. Move. In this way, for example, a reduction motor can be used, and the drive mechanism can be simplified.
In a preferred embodiment, the first tube portion and the second tube portion are arranged in parallel,
The drive mechanism linearly moves the heat transfer device in a direction perpendicular to the longitudinal direction of the first tube portion and the second tube portion. In this way, the drive mechanism can be a simple mechanism such as a linear solenoid.
In a preferred embodiment, the heating member, the heat radiating member, and the cooling member exchange heat with the fluid. The heating member, the cooling member and the heat absorbing member can have a number of metal fins exposed in the fluid.
In a preferred embodiment, the heating member, the heat radiating member, and the cooling member exchange heat with an external fluid through a heat pipe. Thereby, even if it arrange | positions a heating member, a cooling member, and a heat absorption member away from a heating source, a heat radiation source (for example, air | atmosphere), and a heat absorption source (for example, indoor air), efficient heat transfer is attained. In addition, as a heat pipe, the loop type heat pipe which has the nozzle and diff user which this inventor is pending can be used suitably.

In a preferred embodiment, the first cylindrical portion, the second cylindrical portion, the heating member, the cooling member, the heat absorbing member, and a heat insulating material that is disposed in a portion excluding their relative motion space and suppresses heat transfer therebetween. Thereby, useless heat loss can be reduced.
In a preferred embodiment, there is a cavity for dropping dust below the lowest part of the contact surface of the heating member, the cooling member and the heat absorbing member with respect to the first and second tube parts. In this way, the dust that has fallen on the contact surface where heat conduction is performed falls further downward without staying on the contact surface, so that good heat conduction can be ensured.
In a preferred embodiment, since the device is disposed directly under the solar collector, the device can be configured compactly when solar heat is used as a heating source. Furthermore, heat transfer can be favorably performed while reducing the temperature drop from the solar collector to the heating member of the apparatus. Further, when the heat absorbing member exchanges heat with the indoor heat exchanger, for example, by a heat pipe, the liquid in the heat pipe condensed by the heat absorbing member can fall into the indoor space below due to gravity, and therefore, to the indoor heat exchanger. The heat transfer becomes easier. Of course, a cooling fin may be provided on the heat-absorbing member, and the air flow cooled by the cooling fin may be guided into the room by a duct.
In a preferred embodiment, the solar collector is disposed obliquely or vertically, the first tube portion and the second tube portion are disposed in parallel to each other at a predetermined distance in the horizontal direction, and the drive mechanism includes the heating member, The first cylinder part and the second cylinder part are reciprocated horizontally relative to the cooling member and the heat absorbing member. In this way, the apparatus can be configured compactly.

In a preferred embodiment, the heat sink has a heat dissipating fin structure that is located directly below the sorption type cooling device and dissipates heat to the air flow, and the cooling member dissipates heat to the heat dissipating fin structure. Thereby, the apparatus can be configured more compactly. In a preferred aspect, the heat transfer control mechanism performs the relative movement by a motor or a solenoid fed from a solar cell. Since this solar heat sorption type cooling device operates when solar heat is large, the device can be operated without providing a power storage device for a solar cell that cannot generate power when sunlight does not exist. Also, power wiring on the roof can be omitted.
In a preferred embodiment, the second cylinder part is mounted on the vehicle while incorporating a sorbate absorbent material having a lower sorbate binding property than the sorbent of the first cylinder part. The sorbate absorbing substance having a weak sorbate binding property may be, for example, a cloth or a fibrous material that can hold a sorbate such as water by a certain degree of capillary action. In this way, even if the vehicle vibrates greatly, liquid sorbate such as water does not scatter from the second tube portion.
In a preferred aspect, the communication pipe portion is disposed at a central portion in the radial direction of the first cylindrical portion and is coupled to a central portion of the end wall of the first cylindrical portion so as to be capable of sorbate movement. It is joined to the end wall of one cylinder part through a hermetic seal layer. If it does in this way, the heat transfer from the 1st cylinder part to the 2nd cylinder part through a communicating pipe part can be reduced with the big thermal resistance of a hermetic seal layer. In vacuum vessels such as light bulbs, electrode support by a hermetic seal layer is known, but it has been conventionally known to employ a hermetic seal layer to reduce heat loss in the first tube portion of the sorption type cooling device. It wasn't. Of course, a hermetic seal layer can be similarly provided between the communication tube portion and the second tube portion. Thereby, the heat conduction between the 1st cylinder part and the 2nd cylinder part through a communicating pipe part can further be reduced.

In a preferred aspect, an elastic tube having porosity and elasticity is located at a radially central portion in the first tube portion, and the communication tube portion is disposed at a radially central portion of the first tube portion. The sorbent is filled between the outer peripheral wall of the first tube portion and the porous elastic tube. The sorbent is coupled to the central portion of the end wall of the first tube portion and communicates with the elastic tube. If it does in this way, it can control that discharge of sorbate gas to a communicating pipe part is inhibited by volume change of a sorbent by absorption of sorbate. Note that a good heat conductive material such as a metal wire may be dispersed in the sorbent.
In a preferred aspect, the apparatus includes a permanent magnet that reinforces contact between the heating member, the cooling member, and the heat absorbing member, and the first tube portion and the second tube portion. Thereby, a contact force can be ensured without power feeding to the drive mechanism.
In a preferred embodiment, a heat receiving plate is provided between a high temperature plate and a low temperature plate facing each other at a predetermined interval, the high temperature plate is heated by a fluid that heats the heating member, and the low temperature plate is cooled by the heat absorbing member. The heat receiving plate contacts the high temperature plate to supply heat to the room, or contacts the low temperature plate to supply cold heat to the room. If it does in this way, air conditioning can be switched by a simple mechanism, without using a damper, a valve, etc.

(Other aspects)
Reduction of the sensible heat loss of the cans of the first cylinder part and the second cylinder part reduces useless heating, useless heat dissipation, and loss of produced cold heat. Increasing the diameter of the cans of the first and second cylinders leads to an increase in the mass of the can due to an increase in the can thickness in order to increase the required pressure resistance. Bring.
The minimum can body mass of the first tube portion and the second tube portion that secures the necessary amount of sorbent and sorbate necessary for batch operation is obtained by manufacturing the first tube portion and the second tube portion in a substantially spherical shape. . However, a spherical can body is more difficult to manufacture than a cylindrical can that can employ, for example, a double-winding sealing technique used in can manufacturing. Further, when the average thickness of the sorbate layer up to the sorbate gas passage (for example, an elastic tube) in the first cylinder portion communicating with the communication pipe portion increases, the gas movement resistance against the movement of the sorbate gas increases. From these results, cylindrical cans are suitable for production. When a substantially spherical can is employed, the contact surfaces of the heating member, the cooling member, and the heat absorbing member should be substantially spherical accordingly. Moreover, a specific can body shape is finally determined by the restriction | limiting of an apparatus accommodation space. For example, when a sorption type cooling device is disposed on the back side of the solar collector, it is preferable to reduce the overall thickness of the device by adopting cylindrical can-shaped first and second cylindrical portions. Batch operation is limited by the amount of sorbent. For example, it is advantageous for downsizing the apparatus to complete one batch cycle in less than 10 minutes. Shortening the batch cycle increases the rate of sensible heat loss due to the can.
In addition, the batch operation sorption type cooling device of the present invention can produce cold heat using waste heat of batteries and inverters of electric vehicles and waste heat of fuel cell vehicles, and is provided on the roof of the vehicle. Cooling can be performed by heat from the solar collector. In addition, cool air for cooling the human body can be generated using heat from a solar heat collector provided for clothes or prevention, or heat from a portable heat generation source (for example, a fuel cell). In addition, in order to cool the fish in the cooler box, the present invention using the heat of a heat generation source (for example, a fuel cell) can be employed. In addition, it is apparent that new and useful cold heat can be produced by operating the apparatus of the present invention using low-temperature heat discharged from a factory boiler or chimney.

The heat switching device of the present invention has a heat receiving plate between a high temperature plate and a low temperature plate facing each other at a predetermined interval, the high temperature plate is heated by a high temperature fluid, the low temperature plate is heated by a low temperature fluid, The heat receiving plate contacts the high temperature plate to supply heat to the outside, or contacts the low temperature plate to supply cold heat to the outside. In this way, it is possible to switch between hot and cold supply by a simple mechanism.
The solar heat utilization apparatus of the present invention is a solar heat collector that is installed at a high place and collects solar heat, a heat consuming apparatus that is installed at a low place and uses the solar heat, and transports heat from the solar heat collector to the heat consuming apparatus. In the solar heat utilization device including a heat transport mechanism, the heat transport mechanism includes a plurality of heat pipes arranged in series, a condensing part of the heat pipe on the high position side, and an evaporation part of the heat pipe on the low position side. The heat transfer member transfers heat from the condensation part of the heat pipe on the high position side to the evaporation part of the heat pipe on the low position side by heat transfer. It is characterized by letting. For example, when transporting heat from the solar collector on the roof to the sorption cooling device described above by heat pipe, or when transporting heat from the solar collector on the roof to a heat consuming device at a lower position by heat pipe, The difference in height between the evaporating part of the heat pipe fixed to the solar collector and the sorption cooling device or heat consuming device installed at the lowest position becomes large. It becomes difficult to lift up the condensed fluid in the heat pipe to the evaporation part at the solar collector position. Therefore, in the present invention, a plurality of heat pipes having a small difference in height between the evaporation part and the condensation part are arranged in series, and the condensation part of the upper heat pipe and the evaporation part of the lower heat pipe are connected with good heat conductivity. It couple | bonds with a heat-transfer member. Thereby, solar heat can be transported without any problem from the roof of a two-story house, for example, to a sorption cooling device or a heat consuming device installed on the first floor or the ground using a heat pipe. Since the heat pipe can make the solar heat collector and the piping system smaller and lighter than the conventional hot water supply type solar heat collector, the cost required for the manufacture and installation work can be reduced. In addition, the amount of heat insulating material that shields the piping and solar collector from heat can be reduced. In a preferred embodiment, the condensing part of the lowermost heat pipe extends to the bathtub and directly heats the water in the bathtub.

In a preferred aspect, the heat transfer member includes a heat transfer plate with good heat conductivity having a groove into which the heat pipe is fitted. Thereby, heat conduction can be performed satisfactorily.
In a preferred aspect, the heat transfer member includes a first heat transfer plate into which the groove of the first heat pipe is fitted, and a second heat transfer plate into which the groove of the second heat pipe is fitted. Is concluded. Thereby, heat conduction can be performed satisfactorily.
In a preferred aspect, the heat pipe is plastically deformed by the fastening. Thereby, heat conduction can be performed satisfactorily.
In a preferred aspect, the first heat pipe and the second heat pipe are in direct contact with each other. Thereby, heat conduction can be performed satisfactorily.

Preferred embodiments of the present invention will be described with reference to the drawings. However, it goes without saying that the present invention should not be construed as being limited to the following embodiments.
(Embodiment 1)
A solar cooling device according to Embodiment 1 that employs the batch operation sorption type cooling device of the present invention will be described with reference to FIG. FIG. 1 is a block diagram of this solar cooling apparatus. 1 is a solar heat collector, 2 is a sorption type cooling device, and 3 is an indoor heat exchanger. 4 is a high-temperature heat pipe that sends the heat of the solar collector 1 to the sorption type cooling device, and 5 is a low-temperature heat pipe that sends the cold heat produced by the sorption type cooling device 2 to the indoor heat exchanger 3. As the heat pipes 4 and 5, it is preferable to use nozzle-diffuser loop heat pipes that have been invented and filed by the present inventors.
The solar collector 1 may be of a normal plate type in which a heat collecting plate is held inside and a glass plate that transmits sunlight is arranged on the surface thereof. The evaporation part of the high temperature heat pipe 4 is in close contact with the heat collecting plate. Of course, a solar collector with a condensing structure can also be adopted. The sorption type cooling device 2 that operates in batch will be described in detail later. The indoor heat exchanger 3 provided in the room is a well-known one that includes an indirect heat exchanger that forms an evaporation portion of the low-temperature heat pipe 5 and a motor fan that causes an air flow to flow through the indirect heat exchanger. The indoor heat exchanger 3 is supplied with cold heat from the sorption type cooling device 2 through a low-temperature heat pipe 5. The low temperature heat pipe 5 can have essentially the same structure as the high temperature heat pipe 4 described later. Further, instead of the low-temperature heat pipe 5, the cooling heat of the sorption type cooling device 2 may be directly introduced into the room by an air flow using a motor fan and a duct. In this case, the indoor heat exchanger 3 is omitted. It is possible to simplify the system configuration. In addition, the indoor heat exchanger 3 and the sorption type cooling device 2 can be provided integrally. In this case, the cold heat is transferred from the sorption type cooling device 2 to the indoor heat exchanger 3 by a heat transfer mechanism. You can also.

  The high temperature heat pipe 4 sends the heat produced by, for example, the solar collector 1 fixed on the roof to the sorption type cooling device 2. Since the condensing part of the high-temperature heat pipe 4 exists below the solar collector 1 as its evaporating part, the circulation of the condensate from the condensing part to the evaporating part (solar heat collector 1) becomes a problem. It may be perfused using a known capillary mechanism, or may be perfused on the high-speed air stream of the nozzle-diffuser loop heat pipe. In addition, at the time of starting the operation of the high temperature heat pipe 4, the condensate needs to be held in the evaporation portion of the high temperature heat pipe 4 existing in the solar heat collector 1. Fortunately, since the solar collector 1 is cooled at a lower temperature than that in the sorption type cooling device 2 by radiative cooling at night, the condensing part of the high temperature heat pipe 4 existing in the sorption type cooling device 2 becomes an evaporation part. Since the evaporating part in the solar collector 1 becomes a condensing part, the liquid can be held in advance in the evaporating part in the solar collector 1 without any problem. In addition, it is suitable for the evaporation part in the solar-heat collector 1 to incorporate fiber chamber materials, such as cloth and mats, which hold the liquid weakly. When the solar collector 1 is heated by the rise of the sun, the liquid in the evaporation part of the high-temperature heat pipe 4 existing in the solar collector 1 evaporates and flows to the sorption type cooling device 2. Note that the high temperature heat pipe 4 may be omitted, and heat may be transferred to the sorption type cooling device 2 by a normal liquid flow or air flow.

Next, the structure of the sorption type cooling device 2 will be described with reference to FIG. FIG. 2 is a schematic plan view for showing the basic operation principle of the sorption type cooling device 2.

The 1st cylinder part 22 and the 2nd cylinder part 24 are connected by the unillustrated communication pipe part which distribute | circulates the water vapor | steam as a sorbate. These communicating pipe parts are connected to the radial direction center part of the upper end wall of the cylinder parts 21-24 which are cylindrical cans.
The 1st cylinder parts 21 and 22 have accommodated the sorbent in the cylindrical can body which consists of a plated iron plate. A sorbent such as activated carbon, zeolite, acrylic polymer, acrylic copolymer, methacrylic acid polymer, and methacrylic acid copolymer having a water vapor sorption function is accommodated inside the first cylindrical portions 21 and 22 so that water vapor can flow. It is also known to disperse metal fins or the like in the first tube portions 21 and 22 in order to improve the thermal conductivity in the second tube portions 23 and 24. The 2nd cylinder parts 23 and 24 are comprised by the cylindrical can body which consists of a plated iron plate. The first tube portions 21, 22 and the second tube portions 23, 24 are separated from each other by 90 degrees around the rotation axis 29, and the first tube portion 21, the first tube portion 22, the second tube portion 24, the second tube portion. They are arranged in the order of 23. The axis of each cylinder part 21-24 is vertical.

The cooling members 25, 26, the heating member 27, and the heat absorbing member 28 are iron members whose horizontal cross section formed by, for example, cast iron or iron plate molding has a substantially ax shape. The side surfaces of the members 25 to 28 on the counterclockwise (CCW) side are cylindrical surfaces A, and the side surfaces of the members 25 to 28 on the clock (CW) side are cylindrical surfaces B. The cooling member 25 is disposed between the tube portions 21 and 23, the cooling member 26 is disposed between the tube portions 22 and 24, the heating member 27 is disposed between the tube portions 21 and 22, and the heat absorbing member 28 is It arrange | positions between the cylinder parts 23 and 24. FIG. The members 25 to 28 have a thickness in the circumferential direction that can be in close contact with only one cylindrical surface outer surface of the cylindrical portions on both sides. The members 25 to 28 are fixed to arms (not shown) that extend radially from the rotation shaft 29. This arm is made of a material having poor thermal conductivity. The rotating shaft 29 is rotated by a reduction motor (not shown), so that the members 25 to 28 can be rotated in the CW direction and the CCW direction.
The high temperature heat pipe 4 has an evaporation portion accommodated in the heating member 27, and the low temperature heat pipe 5 has a condensation portion accommodated in the heat absorbing member 28.

The heat receiving plate 92 is disposed between the high temperature plate 91 and the low temperature plate 93. The thickness of the heat receiving plate 92 is smaller than the gap between the high temperature plate 91 and the low temperature plate 93. As a result, the heat receiving plate 92 can contact only either the high temperature plate 91 or the low temperature plate 93. The main surfaces of the high temperature plate 91, the low temperature plate 93, and the heat receiving plate 92 that serve as contact surfaces are flat surfaces, but this is not essential.

As a result, the heat receiving plate 92 can select either the operation of contacting the high temperature plate 91 to receive heat for heating or the operation of contacting the low temperature plate 93 to receive cold heat. That is, when the heat receiving plate 92 contacts the high temperature plate 91, heat is transferred from the high temperature plate 91 to the heat receiving plate 92. When the heat receiving plate 92 contacts the low temperature plate 93, cold heat is transmitted from the low temperature plate 93 to the heat receiving plate 92.

FIG. Water vapor flowing through the loop heat pipe enters the hole inside the hot plate 91 from the solar collector 1 through the tube portion 42, enters the heating member 27 of the sorption type cooling device 2 from the hot plate 91 through the tube portion 43, and is heated. It returns to the solar collector 1 from the member 27 through the pipe part 41. Thereby, the heating member 27 of the sorption type cooling device 2 is heated only when the high temperature plate 91 does not absorb heat.
The low temperature heat pipe 5 includes pipe portions 51 and 52 that connect the low temperature plate 93 and the heat absorbing member 28 of the sorption type cooling device 2, and is a loop heat pipe that transmits the cold heat of the heat absorbing member 28 to the low temperature plate 93. Become. Reference numerals 94 and 95 denote tube portions of loop heat pipes that connect the heat receiving plate 92 and an indoor heat exchanger (not shown). The heat or cold heat of the heat receiving plate 92 is sent to the indoor heat exchanger through the pipe portions 94 and 95.

In a mode (see FIG. 11) in which the heat receiving plate 92 is brought into contact with the low temperature plate 93 by a driving device (not shown), the high temperature plate 91 does not absorb the heat of the solar heat collector 1. It is sent to the heating member 27. The heat absorbing member 28 of the sorption type cooling device 2 cools the low temperature plate 93 through the low temperature heat pipe 5. The low temperature plate 93 cools the heat receiving plate 92, and the cold heat of the heat receiving plate 92 is sent to the indoor heat exchanger 3 (not shown) through the pipe portions 94 and 95.
In the mode in which the heat receiving plate 92 is brought into contact with the high temperature plate 91 by an unillustrated driving device, the high temperature plate 91 absorbs the heat of the solar collector 1. In this mode, the drive unit of the sorption type cooling device 2 is stopped. Thereby, the heating member 27 of the sorption type cooling device 2 does not absorb heat. The heat of the high temperature plate 91 is transmitted to the heat receiving plate 92 and is sent from the heat receiving plate 92 to the indoor heat exchanger 3 (not shown) through the pipe portions 94 and 95. That is, in this embodiment, it is possible to switch the heat transfer path with a simple structure without using a valve or a damper that complicates the heat transfer system. The contact heat transfer path switching mechanism can be widely used in addition to the sorption type cooling device. Moreover, the heating of the high temperature plate 91 and the cooling of the low temperature plate 93 can be performed by bringing the heat transfer fluid into contact with the fins provided on the back surface or inside of the high temperature plate 91 or the low temperature plate 93 instead of the heat pipe. It may be performed through a thermal mechanism. The movement of the heat receiving plate 92 of the heat switching device 9 may be performed manually. Further, the contact surface is not a flat surface but may be provided with irregularities and grooves. In this case, unevenness should be provided so that two contact surfaces that are in contact with each other are in close contact. Further, a permanent magnet may be disposed in order to improve the adhesion between the high temperature plate 91, the low temperature plate 93 and the heat receiving plate 92. The high temperature plate 91, the low temperature plate 93, and the heat receiving plate 92 may be non-magnetic copper plates having excellent thermal conductivity instead of iron plates. Even in this case, the permanent magnets of the respective plates can sufficiently adhere to each other. Adopting a neodymium magnet or a samarium magnet is suitable.
(Modification)
In the above embodiment, the pipe portions 94 and 95 forming the loop heat pipe transmit heat or cold to the indoor heat exchanger (not shown), but instead of the indoor heat exchanger, the loop heat pipe is connected to the indoor floor portion.
