Generally, dehumidification is
As can be seen in the cooling operation during the rainy season, it only plays an auxiliary role in air conditioning, and the conventional dehumidifiers described above also have known compressors, condensers, expansion valves, evaporators, etc. Only when there is a heat pump type air conditioner can its function be fully demonstrated. And, the air conditioning method and device in which this dehumidifying device and the heat pump type air conditioning device are combined,
It can be easily created by those skilled in the art. However, the air conditioner according to this combination requires two systems, a dehumidifying circuit system (dehumidifying device) using a hygroscopic liquid such as a LiCl aqueous solution as a medium and a refrigerant circuit system (air conditioning device) using refrigerant such as CFC gas. Therefore, there is a problem that the configuration of the device becomes complicated. Further, since the dehumidifying device uses dehydration by the exhaust pump 36 for concentrating the hygroscopic liquid, the exhaust heat released by the condenser of the air conditioner cannot be used for the concentrating, and the exhaust heat is wasted. There is a problem that the energy efficiency of the device is reduced.

Here, since the indoor fan 27 is stopped, the cooled LiCl aqueous solution exchanges heat not with the indoor air but with the cool storage material 5 in the cool storage panel 4, and cold heat is stored in the cool storage material. Then, the LiCl aqueous solution warmed by the heat exchange returns to the tank 7 through the return pipe 9b. In this way, cold heat is stored in the cold storage panel 4 by using the LiCl aqueous solution 8 as a refrigerant. At the same time, the LiCl aqueous solution 8 in the tank 7 is heated by the heat exchanger 14 while being sent through the pipe 12 by the second pump 13, and reaches the temperature control valve 15. The temperature control valve 15 is Li
It is not opened until the Cl aqueous solution reaches a predetermined temperature (for example, 60 ° C.) suitable for dehydration, and the high temperature and high vapor pressure LiCl aqueous solution is fed into the second tube 16. Here, the outside of the second tube 16 has a low vapor pressure and is ventilated with warm air by the outdoor fan 24, so the water content in the LiCl aqueous solution is
Easily and in large quantities, it passes through the water vapor permeable membrane of the tube and is discharged to the outside air. Then, the LiCl aqueous solution concentrated by dehydration returns to the tank 7 through the pipe 12. In this way, the LiCl aqueous solution 8 is simultaneously concentrated by exhaust heat.

Therefore, if the above cold storage / dehydration operation is continued during the night, the cold energy sufficient for radiant cooling during the day is stored in the cold storage panel 4 the next morning, and the LiCl aqueous solution 8 in the tank 7 is sufficient for dehumidification during the day. Only it is concentrated and the water absorption capacity is restored. In the above embodiment, the dehydration circuit 2 is provided with the temperature control valve 15
Since the above is provided, there is an advantage that only the LiCl aqueous solution which is heated by the heat exchanger 14 and has a predetermined temperature suitable for dehydration can be sent to the second tube 16, and the dehydration in the second tube 16 can be performed more effectively. .. Further, the refrigerant circuit 3 is provided between the moisture absorption / cooling circuit 1 and the dehydration circuit 2, the evaporator 23 thereof cools the cooling heat exchanger 11, and the first condenser 20 thereof cools the heating heat exchanger 14. In addition to heating, the second condenser 21 with the outdoor fan 24 sends warm air to the second tube 16, so the exhaust heat generated by cooling the heat exchanger 11 for cooling is The heat exchanger 14 for heating and the LiCl aqueous solution can be effectively used for dehydration, the energy efficiency of the air conditioner can be greatly improved, and further the dehydration by hot air can be further promoted.

Next, during the summer daytime, the cold heat stored in the cool storage material 5 of the cool storage panel 4 is spontaneously released during the night of the previous day, and the air in the room R is radiatively cooled (so-called base air conditioning), and cooling is insufficient. At this time, the indoor fan 27 is rotated to promote cooling by stirring. In addition to this, when dehumidifying the room R, only the first pump 10 of the moisture absorption / cooling circuit 1 is operated while the indoor fan 27 is being rotated to remove the concentrated LiCl aqueous solution 8 in the tank 7. The first tube 6 in the room R is circulated. Since the LiCl aqueous solution sent into the first tube 6 has a high concentration and its water vapor pressure is lower than that in the room R, the water contained in the indoor air sent by the indoor fan 27 passes through the water vapor permeable membrane to the first position. It is absorbed by the LiCl aqueous solution in the tube 6. This dehumidification removes the latent heat load, which occupies a considerable proportion of the indoor cooling load, so that the effect of the base air conditioning can be enhanced.

Further, when the sensible heat load is large during the daytime in summer, auxiliary cooling is supplemented to supplement the base air conditioning. That is, the compressor 18 of the refrigerant circuit 3 is operated with the indoor fan 27 kept rotating, and the heat exchanger 11 for cooling the dehumidifying / cooling circuit 1 is cooled by the evaporator 23.
