Description

  The present invention relates to a dehumidifying device, and more particularly to a low power consumption dehumidifying rotor type dehumidifying device.

  Conventionally, there has been a dehumidifying device that performs dehumidification by utilizing a characteristic that a refrigerant is compressed by a compressor. The principle of dehumidification is that air is introduced into an evaporator in a dehumidifier by a fan. Since the temperature of the evaporator is extremely low (about 5 ° C.), there is a phenomenon that moisture in the air forms water droplets in the meandering tube on the evaporator, which is so-called low temperature dehumidification.

  However, since the dehumidifying capacity greatly depends on the air temperature and the surface temperature of the meandering tube, when the temperature is low in winter or at night, the dehumidifying efficiency is lowered by the drastic reduction of the dehumidifying capacity. Power consumption may increase.

  By the way, as a dehumidifying rotor type dehumidifying device, it is possible to quickly and easily reduce the humidity of air, and dehumidifying that cannot be solved by using other dehumidifying methods in the case of low temperature and low humidity, etc. The area can be effectively realized.

  The dehumidification principle uses the moisture absorbing material of the dehumidification rotor (for example, porous silica gel or zeolite), and physically separates the moisture in the air by dividing the dehumidification rotor into a dehumidification region and a regeneration region by a partition plate. Heat adsorbed on the hygroscopic material, vaporizes the water adsorbed on the hygroscopic material in the regeneration region, forms high-temperature and high-humidity air at the inlet of the AC heat exchanger, and the temperature is lowered by the cold air in the room As it passes through the exchanger, it is condensed and discharged as water due to the difference in dew point. Moreover, when a combination process is performed, since a preferable air dew point can reach to -40 degreeC, it attracts much attention.

  FIG. 1 is a diagram schematically showing that a conventional dehumidifying rotor type dehumidifying device dehumidifies air. As shown in FIG. 1, members such as a heat exchanger 10, a dehumidifying rotor 12, a dehumidifying fan 14, an electric heater 16, and a regeneration fan 18 are provided in the main body 100, and a dehumidifying rotor 12 is disposed on one side. It has area | region 12A and the reproduction | regeneration area | region 12B, and drives rotation of the dehumidification rotor 12 with the drive device 12C.

  As an operation for dehumidifying the air described above, first, external heat air A1 (temperature is about 21.5 ° C. and relative humidity is 31%) introduced from the outside of the main body 100 is transferred by the heat exchanger 10. Heat exchange is performed with high-temperature humid air (temperature is about 29.9 ° C.), moisture in the air is adsorbed to the dehumidification region 12A of the dehumidification rotor 12, and dry air A3 (temperature is about 39 ° C.) on which moisture is adsorbed. Extraction by the dehumidifying fan 14 realizes a dehumidifying function of air, and the rotation of the dehumidifying rotor 12 is driven by the driving device 12C so that the area of the dehumidifying rotor 12 in which moisture is adsorbed (that is, located in the original dehumidifying area 12A) The area is moved to the regeneration area 12B, and moisture is heated and desorbed.

  First, the regeneration air B1 having a relative humidity of 20% in the flow path with respect to the regeneration region 12B is heated to 110 ° C. or higher by the electric heater 16, and the regeneration hot air B2 is supplied to the regeneration region 12B of the dehumidifying rotor 12. The regenerative air B3 (with a temperature of about 59 ° C. and a relative humidity of 100%) is discharged by the regenerative fan 18 by flowing and dehumidifying the moisture therein, and the regenerative air B3 is exhausted by a pipe through the heat exchanger 10. Then, the moisture is condensed, and the condensed moisture flows to the water collector at the bottom of the dehumidifier through the flow path in the heat exchanger 10 to collect the moisture.

  The air B4 (the temperature is about 45 ° C. and the relative humidity is 100%) discharged by heat exchange by the heat exchanger 10 is heated to the air B1 of about 10 ° C. by the electric heater 16, and is attached to the dehumidifying rotor 12. Remove moisture. In this way, after the secondary condensation heat (that is, water molecules in the air form water droplets in the dehumidification region 12A of the dehumidification rotor 12) from the regeneration air circulation region of the dehumidification rotor 12, the water droplets are evaporated in the regeneration region 12B of the dehumidification rotor 12 The water is condensed and discharged as water droplets by the heat exchanger 10.

  Therefore, in order to dehumidify 1 liter of water, the condensation heat of 1 liter of water is required twice. This part of the heat loss must be supplemented by the heating of the electric heater 16, i.e. the power energy for heating 45 ° C to 110 ° C. As for the current dehumidifying device, the power consumption is about 670 W / hr, of which about 600 W is generated by the electric heater, so that the power consumption required for air dehumidification is greatly increased. Therefore, the current dehumidification rotor type dehumidifier is still a product with high power consumption.

  Therefore, providing a low power consumption dehumidifying device for reducing power consumption is a problem to be solved in the industry.

In order to make the description of the present invention easier to understand, in the accompanying drawings, the drawings are described by taking the dehumidifying member as a dehumidifying rotor as an example.

(First embodiment)
FIG. 2 is a configuration diagram schematically showing a first embodiment of a low power consumption dehumidifier according to the present invention. In order to make the present invention easier to understand, in FIG. 2, the drawings will be described by way of example in which the heat conducting member is composed of a thermoelectric cooler (TEC), but the present invention is limited by these drawings. is not. As shown in FIG. 2, the low power consumption dehumidifying apparatus according to the present invention includes a main body 200, a dehumidifying rotor 20, thermoelectric coolers 22 and 24 (that is, a heat conducting member), and an electric heater 23, and the thermoelectric cooler. Each of 22 and 24 has a cooling side 221 and 241 and a heating side 222 and 242.

  Specifically, the thermoelectric coolers 22 and 24 are formed by mutually arranging P-type and N-type semiconductor dies in P-type and N-type semiconductor elements. The P-type and N-type semiconductor elements are connected as a complete circuit by a general conductor, and are generated by a temperature difference or a temperature difference caused by a current based on the Peltier effect and the Seebeck effect. That is, the cooling side 221 and 241 and the heating side 222 and 242 exchange heat with each other by the physical phenomenon of the current. Since the operation principle of the thermoelectric coolers 22 and 24 is well known, detailed description thereof is omitted here. Hereinafter, the operation principle of the dehumidifying apparatus according to the present embodiment will be described in detail.

  The main body 200 has a first channel (see, for example, the notation of arrows A1 ′ to A3 ′) and a second channel (see the notation of arrows B1 ′ to B4 ′). One flow path sucks external humid air A1 ′, and the second flow path has condensation regions B3 ′ and B4 ′ and heating regions B1 ′ and B2 ′.

  A dehumidification rotor 20 is provided in the main body 200, the dehumidification rotor 20 has a dehumidification region 20A, a regeneration region 20B, and a drive device 20C, and the external humid air A1 ′ is dehumidified from the inlet of the processing air A2 ′. 20A enters and absorbs moisture in the air, and the dry air A3 ′ is discharged to the environment to be dehumidified outside the dehumidifier by the extraction of the dehumidifying fan 14.

  Then, the moisture adsorbing region is driven by the driving mechanism 20C through the dehumidification rotor 20 to the regeneration region 20B to perform the heat desorption processing of the moisture, whereby the heating side of the thermoelectric cooler 24 in the moisture desorption processing flow is performed. The regenerative air B1 is heated to the humid hot air B2 ′ (110 ° C.) via the 242 and the wet hot air B2 ′ is passed through the dehumidifying rotor 20 so that the wet hot air B2 ′ formed by desorption of moisture therein is converted into the thermoelectric cooler 22. The air is cooled by the cooling side 221 to condense the moisture, so that the condensed moisture flows into a water collector (not shown) at the bottom of the dehumidifying device, moisture is collected, and then the moisture is desorbed. B4 ′ is introduced into the regeneration region 20B on the second side of the dehumidification rotor 20 by the heating side 222 of the thermoelectric cooler 22, and the high temperature for heating the dehumidification rotor 20 is revised. Heated by electric heater 23 so as to circulate.

  Specifically, since the temperature of the heating side 242 of the thermoelectric cooler 24 can reach about 80 ° C. to 90 ° C., if the electric heater 23 only increases the power consumption of 20 to 30 ° C., the regeneration air B2 Since the requirement of heating to 'can be satisfied, power consumption is saved because a conventional dehumidifier (110 ° C-50 ° C = 60 ° C) is not necessary.

(Second embodiment)
Since the dehumidifying apparatus according to the second embodiment is similar to the operating principle of the dehumidifying apparatus according to the first embodiment described above, detailed description thereof is omitted here.
FIG. 3 is a configuration diagram schematically showing a second embodiment of the low power consumption dehumidifier according to the present invention. The second embodiment is different from the first embodiment in that a heat exchanger 21 is further provided in the second embodiment. The external moist air shown in FIG. 2 enters the dehumidification area 20 </ b> A of the dehumidification rotor 20 after heat exchange by the heat exchanger 21. As shown in FIG. 2, the moisture and hot air treated by the thermoelectric cooler 22 is introduced into the heat exchanger 21 via the condensation regions B3 ′ and B4 ′ of the second flow path, and cooled to condense moisture. Then, the condensed water flows into the water collector (not shown) at the bottom of the main body 200 of the dehumidifying device via B3 ′ and B4 ′ of the second flow path to collect the water. Since the dehumidifying device of the second embodiment is the same as the operating principle of the dehumidifying device of the first embodiment described above, detailed description is omitted here.

  In any of the above-described embodiments, the regeneration air from which moisture has been desorbed is directly heated by the thermoelectric cooler 24, or the regeneration air from which moisture has been desorbed is heated by the thermoelectric cooler 24 and then heated by the electric heater 23. Therefore, it is not necessary to directly heat the regenerated air to a predetermined temperature by an electric heater as in the past, because the desorption of moisture is performed by flowing hot air having a sufficient temperature to the dehumidifying rotor 20. The dehumidifying apparatus according to the present invention is designed to save power consumption.

(Third embodiment)
FIG. 4 is a block diagram schematically showing a third embodiment of the low power consumption dehumidifier according to the present invention. As shown in FIG. 4, the third embodiment is different from the first embodiment described above in that the thermoelectric coolers 22 and 24 described above are added to the refrigeration circulation system in the heat conduction member in the third embodiment. It has been replaced.

  As shown in FIG. 4, the refrigeration circulation system includes a compressor 260, a first condenser 261, a second condenser 262, an expansion valve 264, an evaporator 266, and an operation that flows between the members. Fluid L (for example, a refrigerant). The main body 300 also has a first channel (see the notation of arrows A1 ′ to A3 ′) and a second channel (see the notation of arrows B1 ′ to B6 ′). The external flow path introduces external humid air A1 ′, and the second flow path includes condensation regions B3 ′, B4 ′ and heating regions B1 ′, B2 ′, B5 ′, B6 ′. The heat exchanger 21 is provided in the two flow paths B3 ′, B4 ′, and the heat exchanger 21 is located between the condensation areas B3 ′, B4 ′ of the second flow path of the dehumidification rotor 20 and the evaporator 266. doing. Among these, the working fluid L flows in order through the compressor 260, the first condenser 261, the second condenser 262, the expansion valve 264, and the evaporator 266. That is, the first condenser 261 is close to the heating region B <b> 2 ′ of the second flow path of the dehumidification rotor 20, and the second condenser 262 is located on the downstream side of the first condenser 261. Hereinafter, the dehumidifying principle of the dehumidifying apparatus according to the present embodiment will be described in detail.

  The treated air A2 ′ obtained by treating the external moist air A1 with the heat exchanger 21 enters the dehumidifying region 20A of the dehumidifying rotor 20 and absorbs moisture in the air, and then the dried air passes through a flow path (not shown). It is discharged to the outside of the dehumidifier via. The dehumidification rotor 20 drives the area where moisture is adsorbed by a drive mechanism (not shown) to the regeneration area 20B to perform heat desorption processing of moisture. At the beginning of the heat desorption treatment flow of moisture, the regeneration air is heated to high-temperature air by the compressor 260 (high pressure and high temperature) and the first condenser 261, and the high-temperature air is caused to flow to the dehumidification rotor 20, whereby the moisture therein Is formed into wet regenerated air B3 ′, and the wet heat air B3 ′ in the second flow path is cooled by the heat exchanger 21, thereby condensing water B4 ′.

  Then, after the temperature is lowered by flowing through the evaporator 266, the humidified air B5 ′ and B6 ′ whose temperature has been improved by the compressor 260 is obtained, and then flows through the first condenser 261 and the second condenser 262, respectively. This cycle is repeated by heating the regeneration air B1 ′ to the hot air B2 ′ due to the difference in temperature. Specifically, the working fluid L that has flowed into the first condenser 261 from the compressor 260 becomes high-temperature condensation (the tube wall surface temperature is about 95 ° C.), and the second condenser 262 causes low-temperature condensation. (The tube wall surface temperature is about 50 ° C.), and then the temperature and pressure are reduced by the expansion valve 264 and the evaporator 266, and then the process returns to the compressor 260 to complete the refrigeration cycle. When the air B1 ′ flows through the first condenser 261, the heating can be performed by the high temperature of the tube wall condensed at high temperature.

  Thus, since the electric heater 23 only needs to supply heating power energy of about (110 ° C.−90 ° C. = 20 ° C.), it directly passes through the second condenser 262 (110 ° C.−50 ° C. = 60 ° C.). Compared to the heating power energy, the power consumption of the electric heater 23 can be relatively reduced, and the cycle of the entire refrigeration system is not affected.

(Fourth embodiment)
FIG. 5 is a configuration diagram schematically showing a fourth embodiment of the low power consumption dehumidifier according to the present invention. As shown in FIG. 5, the fourth embodiment is different from the third embodiment described above in that the evaporator 266 is different from the first side of the dehumidification rotor, the heat exchanger 21 and the fourth embodiment. It is a point located between. If comprised in this way, since the temperature of the refrigerant | coolant which enters into the compressor 260 will become high and the refrigerating capacity of a refrigerant | coolant will become comparatively weak, the dehumidification amount of the whole dehumidification apparatus will become comparatively low. Since the dehumidifying device in the fourth embodiment is similar to the operating principle of the dehumidifying device in the third embodiment described above, detailed description is omitted here.

(Fifth embodiment)
FIG. 6 is a configuration diagram schematically showing a fifth embodiment of the low power consumption dehumidifier according to the present invention. As shown in FIG. 6, the fifth embodiment is different from the third and fourth embodiments described above in that the evaporator 266 in the fifth embodiment faces the dehumidification rotor 20 and the regeneration region 20B. The dry air A3 ′, which is located in the heating region B6 ′ of the second flow path on the opposite side of the flow path and flows out of the dehumidification rotor 20 along the first flow path, flows through the evaporator 266, so that the dry air A3 'Is discharged at an appropriate temperature according to the demand for the refrigerating capacity (for example, an appropriate temperature for the human body is 27 ° C). Since the dehumidifying apparatus according to the sixth embodiment is similar to the operating principle of the dehumidifying apparatuses according to the third and fourth embodiments described above, detailed description thereof is omitted here.

(Sixth embodiment)
FIG. 7 is a configuration diagram schematically showing a sixth embodiment of the low power consumption dehumidifier according to the present invention. As shown in FIG. 7, the sixth embodiment is different from the third embodiment described above in that, in the sixth embodiment, the heat conducting member further includes the second condenser 262 and the expansion valve 264. And the third condenser 263 located in the heating region B6 ′ of the second flow path and close to the dehumidifying member, and omitting the installation of the heat exchanger 21, that is, The point is that heat exchange is directly performed between the evaporator 266 and the first condenser 261. Thus, since it is not necessary to devise any heat exchanger 21, it is not necessary to use the structure of the electric heater 23. Since the dehumidifying apparatus according to the sixth embodiment is similar to the operating principle of the dehumidifying apparatus according to the fifth embodiment described above, detailed description thereof is omitted here.

  The dehumidifying apparatus shown in FIGS. 4 to 7 described above directly heats the regenerated air from which moisture has been desorbed by the compressor 261 or heats the regenerated air from which moisture has been desorbed by the combination of the compressor 261 and an electric heater. Since dehumidification is performed by flowing hot air having a sufficient temperature to the dehumidification rotor 20, there is no need to heat the regenerated air directly to a predetermined temperature with an electric heater as in the prior art. Power consumption is more saved.

  Also, it should be noted that in another embodiment of the present invention, the compressor 261 can be replaced with a heat pipe, that is, the heat conducting member is a sealed chamber having a condensing side and an evaporating side. Is formed with a capillary structure (similar to an expansion valve) between which the working fluid flows, and the evaporator serves as a cooling side and is located in the condensation region of the second flow path, and the condensation side serves as a heating side. And located in the heating region of the second flow path. However, since the heat tube structure is a conventional member, its operating principle is similar to that of the above-described embodiment, and therefore detailed description thereof is omitted here.
