The heating device 130 may include various heating devices 130 such as a heating coil or a hot water heat exchanger that are heated by electricity.

Here, when the hot water heat exchanger is used as the heating device 130, waste heat remaining in various power generating facilities or industrial facilities can be used to provide hot water. In particular, if hot water is supplied to a hot water heat exchanger by using waste heat in a summer season where the cooling load is much higher than a heat load, consequently, the waste heat energy is used for cooling, thereby maximizing energy efficiency nationwide. In addition, hot water can be supplied using solar heat, geothermal heat, or gas as a heat source.

The dehumidifying rotor 110 is preferably formed of a honeycomb-shaped porous structure composed of ceramic paper, and a dehumidifying agent such as a silica gel is stably coated on the surface of the ceramic paper.

A sensible heat rotor (not shown) and a regenerative evaporative cooler (not shown) are well known in the art and will not be described in further detail herein.

The vapor compression type cooler 200 has the same construction as that of the conventional electric air conditioner and includes a compressor 210 for compressing the refrigerant, a condenser 220 for condensing the refrigerant compressed by the compressor 210, An expansion valve 230 for expanding the refrigerant condensed by the expansion valve 230, and a compressor 210 for evaporating the refrigerant expanded by the expansion valve 230. The refrigerant is further cooled by the latent heat of evaporation of the refrigerant, And an evaporator 240 for supplying the evaporator 240.

At this time, the condenser 220 disposed inside the dehumidifying cooling unit 100 and the evaporator 240 disposed in the separate space outside the dehumidifying cooling unit 100 may be connected to each other through the refrigerant pipe 250. Specifically, the refrigerant pipe 250 includes a first refrigerant pipe 250a connecting the compressor 210 and the condenser 220, a second refrigerant pipe 250b connecting the condenser 220 and the expansion valve 230, A third refrigerant pipe 250c connecting the expansion valve 230 and the evaporator 240 and a fourth refrigerant pipe 250d connecting the evaporator 240 and the compressor 210. [ The vapor compression refrigerator 200 has a separate cooling cycle from the dehumidifying refrigerator 100. The refrigerant is circulated through the first refrigerant pipe 250a, the second refrigerant pipe 250b, The refrigerant can be circulated through the compressor 210, the condenser 220, the expansion valve 230 and the evaporator 240 along the third refrigerant pipe 250c and the fourth refrigerant pipe 250d to supply air to the air conditioning space 5 .

The condenser 220 of the vapor compression type cooler 200 is connected to the dehumidifying air cooler 100 through the dehumidifying rotor 110 and the cooler 120 in order to cool the dehumidified and cooled low- And may be disposed on the downstream side of the cooler 120 in the cooling passage 2. However, the present invention is not limited to this embodiment. The dehumidifying cooling passage 2 and the condenser 220 may be arranged so that the cooled air discharged from the dehumidification cooling passage 2 through the first outlet 142 can be transmitted to the condenser 220. [ (Not shown) so that the condenser 220 is cooled by the cooled air passing through the cooler 120.

In addition, the condenser 220 may further include an evaporative water injector 225. Referring to FIG. 2, the evaporation water injector 225 is installed at an upper portion of the condenser 220 to spray water to the condenser 220. The water sprayed on the surface of the condenser 220 is evaporated by the low temperature and low humidity air passing through the cooler 120. At this time, the water takes the heat of the refrigerant flowing in the refrigerant pipe 250 and evaporates, The cooling effect is further increased. On the other hand, the air transferred from the cooler 120 to the condenser 220 is heated and humidified by the evaporated water vapor passing through the condenser 220, and is exhausted to the outside through the condenser 220 and the first outlet 142 .

At this time, the evaporation water injector 225 is not installed only on the upper part of the condenser 220, but may be disposed on the side or the lower side so as to evaporate and cool the condenser 220 by spraying water on the surface of the condenser 220 Of course.

Also, the evaporator 240 may be disposed in a separate space outside the dehumidifying cooler 100. For example, the evaporator 240 may be installed in the air conditioning space 5. That is, the evaporator 240 can perform the role of supplying cooling to the air conditioning space 5 by the latent heat of evaporation by evaporating the refrigerant sequentially passing through the compressor 210, the condenser 220, and the expansion valve 230 have.

Meanwhile, although the compressor 210 and the expansion valve 230 are illustrated as being disposed outside the dehumidifying cooler 100, the embodiments of the present invention are not limited thereto. That is, the condenser 220 is connected to the dehumidification cooling passage 2 of the dehumidifying cooling machine 100 and the evaporator 240 is connected to the compressor 210 and the expansion valve (not shown), as long as the evaporator 240 is installed in a separate space outside the dehumidifying cooling machine 100 230 may be installed in the dehumidifying cooler 100 or the vapor compression type cooler 200 or may be installed in a separate space from the dehumidifying cooler 100 and the vapor compression cooler 200.

Next, the effect of cooling the condenser 220 of the vapor compression type cooler 200 by the cooling produced by the dehumidification cooling device 100 will be described with reference to FIGS. 3 to 5. FIG. FIG. 3 is a graph showing the Ph diagram of the refrigerant R410A circulating in the refrigerant tube of FIG. 1, and FIG. 4 is a graph showing the change of the coefficient of performance (COP) of the vapor compression refrigerant according to the condensation temperature change of the condenser of FIG. And FIG. 5 is a graph showing a required air flow rate required to supply a cooling output of 10 kW in accordance with the change of the regeneration temperature of the dehumidifying rotor of FIG.

3, A is a graph showing a change in pressure according to the enthalpy of the vapor compression refrigerant 200 when the condensing temperature of the condenser 220 is 30 ° C, and B is a graph showing a change in the condensation temperature of the condenser 220 when the condensing temperature is 50 And the pressure change according to the enthalpy of the vapor compression type cooler 200 is shown. Here, a and a 'represent a state in which the refrigerant is compressed as it passes through the compressor 210, b and b' represent a state where the compressed refrigerant condenses as it passes through the condenser 220, and c and c ' The condensed refrigerant expands while passing through the expansion valve 230, and d and d 'represent a state in which the expanded refrigerant evaporates through the evaporator 240.

Here, the required power of the compressor 210 required for the cooling cycle can be determined with reference to a and a ', and the cooling capacity of the vapor compression type cooler 200 can be confirmed through the lengths d and d'. That is, the length of a 'is longer than the length of a, which means that the required power of the compressor 210 is larger when the condensing temperature of the condenser 220 is 30 ° C, and when the condensing temperature of the condenser 220 is 50 ° C (A) , the length of d is longer than d 'when the condensing temperature of the condenser 220 is 30 ° C. (A) when the condensing temperature of the condenser 220 is 50 ° C. (B).

Accordingly, when the condensation temperature of the condenser 220 is 30 ° C, the condenser temperature is 50 ° C, the smaller the cooling capacity d ) Can be obtained.

More specifically, the conventional air-cooled vapor compression type cooler (not shown) cools the condenser 220 to the outdoor air rather than the cooling air supplied from the dehumidifying air conditioner as in the embodiment, , And 40% RH, the condensation temperature of the condenser 220 by the air-cooling type is approximately 50 ° C. Therefore, in the case of an air-cooled vapor compression type cooler (not shown) that uses outdoor air for cooling the condenser 220, it takes the form of a cooling cycle as shown in FIG. 3B.

On the other hand, the temperature of the air obtained in the dehumidifying cooling unit 100 is about 30 to 35 ° C., which is 15 to 20 ° C. lower than the outdoor air, and the air obtained from the dehumidifying cooling unit 100 is used to cool the condenser 220 The condensing temperature of the condenser 220 can be lowered by about 20 ° C compared to the conventional air-cooled vapor compression type cooler (not shown). In addition, as described above, the condenser 220 may further include an evaporation water injector 225 to further lower the condensation temperature of the condenser 220 by using latent heat of evaporation of water by spraying water to the condenser 220.

Thus, if the air obtained from the dehumidifying cooling machine 100 is used to cool the condenser 220 of the vapor compression cooling machine 200, a larger cooling output can be obtained with a smaller compressor input.

Next, referring to FIG. 4, how the cooling cycle efficiency, that is, the coefficient of performance (COP) of the vapor compression type cooler 200 changes according to the change in the condensation temperature will be described.

4, when the refrigerant is R410A and the evaporation temperature is 10 占 폚, superheating is 5 占 폚, subcooling is 5 占 폚, compressor efficiency is 0.7, and the condensation temperature is 50 占 폚, the conventional air- Not shown) is 3.8. In the case where the air obtained in the dehumidifying cooling unit 100 is used for cooling the condenser 220 as in the embodiment, for example, when the condensation temperature is 30 ° C, the coefficient of performance of the vapor compression cooling unit 200 Is 8.8, which is more than twice as high as that of the conventional air-cooled steam compression type air conditioner (not shown) of 3.8.

Next, the change in the required air flow for supplying the cooling output of 10 kW in accordance with the change in the regeneration temperature of the dehumidification rotor 110 will be briefly described with reference to Fig.

Referring to FIG. 5, C represents a case where cooling is supplied to the dehumidification cooling system 1 of one embodiment, and D represents a case where cooling is supplied by a conventional hybrid dehumidification cooling system (not shown). In the case of C, that is, in the case of the dehumidification cooling system 1 according to one embodiment, the conventional hybrid dehumidification cooling system It can be seen that the required air volume is about half that of the system (not shown).

This is because, as described above, in one embodiment, the outlet air of the dehumidifying air cooler 100 is used for evaporative cooling of the condenser 220, thereby improving the cooling performance. As a result, the hybrid dehumidification cooling system (not shown) Which means that the same cooling output can be achieved with the air volume.

If the required air volume is small, the capacity of the main components of the dehumidification cooling system 1 such as the dehumidification rotor 110 and the cooler 120 becomes small, and the required power and regenerated heat amount also become small.

Next, a dehumidification cooling system 10 capable of directly supplying the air produced by the dehumidifying cooling apparatus 100 to the air conditioning space 5 for ventilation purposes will be described with reference to FIG. 6 is a configuration diagram showing a dehumidification cooling system 10 according to another embodiment.

6, the dehumidifying cooling system 100 includes a ventilation inlet 150 formed in the dehumidification cooling passage 2 to recover air from the air conditioning space 5 and to introduce air immediately before the condenser 220, And a ventilation air supply mechanism 160 for supplying a part of the air that has passed through the cooler 120 to the air conditioning space 5.

The dehumidification cooling system 10 according to this embodiment is capable of supplying fresh outside air for indoor ventilation during the cooling operation to the air conditioning space 5. The dehumidification cooling system 10 includes a dehumidifying rotor 110 and a cooler 120, And the air recovered in the air conditioning space 5 is introduced again just before the condenser 220 and used to cool the condenser 220. In this case, the amount of ventilation required in the general house is about 4 to 5 CMM, and air volume of 30 to 40% is added to the supply air volume 12 CMM of the dehumidification cooling system 1 having the cooling capacity of 10 kW to be used for ventilation.

In detail, the dehumidification cooling system 10 according to another embodiment shown in Fig. 6 can supply cooling to the air conditioning space 5 and at the same time can utilize the characteristics of ventilation, deodorization, antibacterial, etc. which are major advantages of the dehumidifying air conditioner 100 have. In addition, since only a small amount of air volume can be supplied for the purpose of ventilation, it is not necessary to provide a separate duct, and the ventilation duct already installed in the air conditioning space 5 can be used as it is.

The air flowing back into the air conditioning space 5 immediately before the condenser 220 is air exhausted from the air conditioning space 5 through the dehumidifying rotor 110 and the cooler 120, I have to be high. In this case, however, if the temperature of the air in the air conditioning space 5 is 27 ° C. and the humidity is 50% RH, the wet bulb temperature rise at the inlet of the condenser 220 is only 1 ° C., There is no big difference.

Hereinafter, with reference to FIG. 7, the structure of the dehumidification cooling system 20 that can be operated by the energy recovery ventilator during spring, autumn, and so forth other than the cooling operation will be described. 7 is a configuration diagram showing a dehumidification cooling system 20 according to another embodiment.

7, the dehumidifying cooler 100 is formed in the regeneration passage 3 to recover the air in the air conditioning space 5 and to provide a ventilation dedicated inlet 170 for introducing air between the air supply mechanism 143 and the dehumidification rotor 110, And a ventilation-dedicated air supply device 180 formed in the dehumidification cooling passage 2 for supplying the air having passed through the dehumidification rotor 110 to the air conditioning space 5.

The dehumidifying cooling system 20 according to another embodiment of the present invention is operated only for ventilation when cooling is not required. In this case, the dehumidifying cooling system 100, the heating device 130, The condenser 220 of the compression type cooler 200 is not operated and the dehumidification rotor 110 is operated as the total heat exchanger without performing the dehumidification function.

At this time, the ventilation operation is performed as follows. First, the air recovered from the air conditioning space 5 flows into the ventilation dedicated inlet 170, passes through the regeneration passage 3, passes through the dehumidification rotor 110, and transfers sensible heat and latent heat of the air to the dehumidification rotor 110. The sensible heat and the latent heat transferred from the air recovered in the air conditioning space 5 to the dehumidification rotor 110 flow into the intake port 141 in accordance with the rotation of the dehumidification rotor 110 and are supplied to the dehumidification cooling passage 2 The outside air is transferred to the outside air, and the outside air, which has received the sensible heat and the latent heat, flows into the air conditioning space 5 again through the ventilation dedicated air supply unit 180.
