Abstract

PROBLEM TO BE SOLVED: To make the size compact and minimize the installation area by including mainly a first flow path part extending below in the vertical direction and a second flow path extending above in the vertical direction in a regenerated air flow path. SOLUTION: Air to be treated A from an air-conditioner 101 is returned by a blower 102 through a desiccant rotor 103 filled with a desiccant, a treated air cooler 300 as a heat exchanger and a coolant evaporator 210 to maintain the air-conditioning space 101 under a comfortable environmental condition. The treated air cooler 300 performs the heat exchange between the sir to be treated A and a cooling air (an atmosphere C) through a coolant to cool the air A and heat the atmosphere C. The regenerated air from an outdoor OA is again evacuated through an exchanger 121 which exchanges heat with the regenerated air B right after passing through the desiccant rotor 103, a coolant condenser 220, the rotor 103, a blower 140 and a heat exchanger 121. Thus it is possible to gather the flow of the regenerated air B in the device in the vertical direction with a main apparatus without changing the direction of the flow before and after the rotor 103. Thus the device is made compact and the installation area is reduced.

In FIG. 2, alphabet symbols D, E, K to N, Q, R,
The state of air in each part is indicated by TV. This symbol corresponds to the circled alphabet in the flow diagram of FIG.

First, the flow of the processing air A will be described. In FIG. 2, the processing air A from the air-conditioned space 101 (state K)
Is sucked in by the blower 102 through the processing air flow path 107 and is taken in by the air RA, and the processing air A flow path 108
Through the desiccant rotor 103. Here, moisture is adsorbed by the desiccant in the aforementioned drying element to lower the absolute humidity, and the dry bulb temperature is raised by the heat of adsorption of the desiccant to reach the state L. This air is sent to the first section 310 of the processing air cooler 300 through the processing air flow path 109, where it is cooled by the refrigerant evaporated in the evaporating section 251 while maintaining the absolute humidity constant, to form M air. Then, the refrigerant enters the refrigerant evaporator (cooler as viewed from the processing air) 210 through the flow path 110. Here, the air is further cooled at a constant absolute humidity to be in the state N.
This air is dried and cooled, returned to the air-conditioned space 101 via the flow path 111 as the processing air A having an appropriate humidity and an appropriate temperature, and supplied with air SA.

Next, the flow of the regeneration air B will be described. In FIG. 2, the regeneration air B (state Q) from the outdoor OA is sucked through the flow path 124 of the regeneration air B, and
It is sent to 1. Here, heat exchange is performed with high-temperature regenerated air (air in state U) B to be exhausted to raise the dry-bulb temperature to become air in state R. This air passes through a flow path 126 and is connected to a refrigerant condenser (a heater as viewed from the regeneration air) 220.
, Where it is heated to raise the dry-bulb temperature and become air in state T. This air passes through the flow path 127 and is sent to the desiccant rotor 103, where it takes water from the desiccant in the above-mentioned drying element and regenerates it, thereby increasing the absolute humidity and the heat of desiccant moisture desorption. The dry-bulb temperature is lowered to reach the state U.

This air passes through a flow path 128 and is sucked into a blower 140 for circulating the regeneration air B.
29, is transferred to the heat exchanger 121 and exchanges heat with the regeneration air (air in state Q) before being sent to the desiccant rotor 103 as described above. It becomes air, and exhaust E

Next, the flow of the outside air C as the cooling fluid will be described. The outside air C (state Q) is sent from the outdoor OA to the second section 320 of the process air cooler 300 through the flow path 171. Here, first, moisture is absorbed by the humidifier 165,
By changing the isenthalpy and increasing the absolute humidity and lowering the dry-bulb temperature, the air becomes state D. State D is almost on the saturation line of the wet vapor diagram. This air is supplied to the second compartment 3
The cooling medium in the condensing section 252 is cooled while absorbing the water supplied by the watering pipe 325 in the inside 20. This air rises in absolute humidity and dry bulb temperature almost along the saturation line, becomes air in state E, passes through the flow path 172, and is exhausted EX by the blower 160 provided in the middle of the flow path 172. You.

Next, with reference to FIG. 1, the flow of the refrigerant in each device will be described, and the operation of the heat pump HP1 will be further described.

In FIG. 1, a compressor 26 compresses a refrigerant.
The refrigerant gas compressed by 0 is guided to a refrigerant condenser (heater as viewed from regenerated air) 220 via a refrigerant gas pipe 201 connected to a discharge port of the compressor 260. The temperature of the refrigerant gas compressed by the compressor 260 is increased by compression, and this heat heats the regeneration air. The refrigerant gas itself is deprived of heat and condenses.

The refrigerant outlet of the refrigerant condenser 220 is connected to the evaporating section 251 of the processing air cooler 300 which is a heat exchanger.
Is connected to the inlet of the evaporator section 251 near the inlet of the evaporating section 251 in the middle of the refrigerant passage 202, and a header 230 having a built-in throttle is provided.

The liquid refrigerant that has exited the refrigerant condenser 220 is decompressed by a throttle (not shown) built in the header 230, expands, and a part of the liquid refrigerant evaporates (flashes). The liquid-gas mixed refrigerant reaches the evaporating section 251, where the liquid refrigerant flows so as to wet the inner wall of the tube of the evaporating section 251 and evaporates, thereby cooling the processing air A flowing through the first section 310. .

Evaporation section 251 and condensation section 2
52 is a series of tubes. That is, since the refrigerant gas is configured as an integral flow path, the evaporated refrigerant gas (and the refrigerant liquid that has not evaporated) flows into the condensing section 252, and is discharged by the outside air C and the sprayed water flowing through the second section 320. It deprives of heat and condenses.

The outlet side of the condensing section 252 is connected to a refrigerant evaporator (a cooler as viewed from the processing air) 210 by a refrigerant liquid pipe 203. A header 240 having a built-in throttle is provided in the middle of the refrigerant liquid pipe 203.
The refrigerant liquid condensed in the condensing section 252 is decompressed and expanded by the header 240 and the throttle 270 having a built-in throttle to reduce the temperature, and enters the refrigerant evaporator 210 through the refrigerant pipe 204 to evaporate. Cool A. As the diaphragms built in the headers 230 and 240, for example, orifices are used. The refrigerant evaporated and gasified by the refrigerant evaporator 210 is guided to the suction side of the compressor 260 for compressing the refrigerant by the refrigerant pipe 205, and the above cycle is repeated.

Next, the operation of the heat pump HP1 will be described. For example, HFC134a may be used as the refrigerant.

The state of the refrigerant outlet of the refrigerant evaporator 210 is a state of a saturated gas. This gas is sucked and compressed by the compressor 260. The refrigerant gas is cooled in the refrigerant condenser 220,
It becomes a state of saturated gas. The refrigerant gas is further cooled and condensed under the same pressure.

This refrigerant liquid is decompressed by a throttle (not shown) built in the header 230 and flows into the evaporating section 251 of the processing air cooler 300. The temperature at this time is about 30
° C. Here, a part of the liquid is evaporated and the liquid and the gas are mixed. In the evaporating section 251, the refrigerant liquid evaporates to reach a point between the saturated liquid line and the saturated gas line.
Here, the liquid has almost completely evaporated.

In the state where the liquid and the gas after the contraction are mixed, the ratio between the refrigerant liquid and the gas is such that the saturated pressure line at 30 ° C. at the pressure after the contraction is below the saturated liquid line and the saturated gas line. Since the difference between the enthalpy of the point and the enthalpy at the time of condensation before constriction by the constriction built in the header 230 is the inverse ratio, the liquid is more in weight ratio. However, since the gas is overwhelmingly larger in volume ratio, the evaporating section 251
In this case, the liquid is mixed with a large amount of gas, and the liquid evaporates while being in a state of wetting the inner surface of the tube of the evaporation section 251.

Next, the refrigerant flows into the condensing section 252. In the condensing section 252, the refrigerant flows into the second compartment 3
The heat is taken away by the outside air C flowing through 20 and / or the sprayed water, and is at a temperature of 30 ° C. on the saturated liquid line.

The refrigerant liquid on the saturation line is supplied to the header 24
The pressure is reduced by a throttle (not shown) built in 0, and reaches a refrigerant evaporator 210 as a mixture of a refrigerant liquid and a gas at 10 ° C.
Here, heat is removed from the processing air A, evaporated and becomes a saturated gas, sucked into the compressor 260 again, and the above cycle is repeated.

Referring to FIG. 3, an example of the mechanical arrangement of the dehumidifying air conditioner described above will be described. In the figure, devices constituting the apparatus are housed in a cabinet 700. The cabinet 700 is formed as a rectangular parallelepiped housing made of, for example, a thin steel plate, and has a suction opening 104 at the lower side in the vertical direction for taking in the processing air A from the air-conditioned space RA. At the opening of the suction port 104, a filter 501 is provided so as to prevent dust in the air-conditioned space from being brought into the apparatus. The blower 102 is installed in the cabinet 700 inside the filter 501, and the suction port of the blower 102 communicates with the suction port 104 of the processing air A of the cabinet via the filter 501.

Further, the desiccant desiccant row 103 can be easily filled, and the distribution of the desiccant in the desiccant rotor 103 can be made uniform. In addition, the blowers 102 and 14 that are movable elements or rotating bodies, including the heavy compressor 260,
If the zero and most of the desiccant rotor 103 are collected in the lower part of the apparatus, that is, in the lower part of the cabinet 700, that is, near the foundation, it is possible to make the apparatus less susceptible to vibration and increase the installation stability of the apparatus.

The outlet of the blower 102 is connected to the desiccant rotor 103 by a flow path 108. Channel 10
8. The above-mentioned flow path 107 is formed so as to be separated from other parts by a thin steel plate similar to that forming the cabinet 700, for example. The processing air A flows into a region of the circular desiccant rotor 103 which is about half (semicircle) as a processing air zone.

Vertically above the desiccant rotor 103,
In particular, a first section 310 of the processing air cooler 300, that is, an evaporating section 251 is arranged above a half (semicircle) region where the processing air A flows. Channel 10 connecting desiccant rotor 103 and first section 310

The space vertically below the refrigerant condenser 220 between the desiccant rotor 103 and the desiccant rotor 103 constitutes a flow path 127, through which a half of the desiccant rotor 103 on the side of the processing air A described above is formed. On the other hand, the configuration is such that the regeneration air B is guided to the other half area as the regeneration air zone. A vertically lower space in a half area of the desiccant rotor 103 through which the regeneration air B passes forms a flow path 128, and a blower 140 is installed in this space with its suction port facing the space. I have.

The discharge port of the blower 140 faces sideward and is connected to the heat exchanger 121 by a flow path 129 defined in the cabinet 700 in a vertical direction. The regenerated air B flowing vertically upward in the flow path 129 and passing through the heat exchanger 121 is supplied to the flow path 124 and the heat exchanger 121 described above.
