As shown by the arrow. Since the LiCl aqueous solution sent into the tube 33 of the moisture absorption module 32 has a high concentration and is far from the throttle 39, its water vapor pressure is lower than that of the room, so the moisture contained in the indoor air sent by the indoor fan 40 is , And is absorbed by the LiCl aqueous solution in the tube 33 through the water vapor permeable membrane. Thus, the LiCl aqueous solution that has absorbed the water is pump 3

題がある。Now, 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 dehumidifier also has a known compressor equipped with a compressor, a condenser, an expansion valve, an evaporator, and the like. Only with a heat pump type air conditioner can its function be fully demonstrated. And the air conditioning method and device combining this dehumidifier and the heat pump type air conditioner,
It can be easily created by those skilled in the art. However, the air conditioner according to this combination requires two systems, a dehumidification circuit system (dehumidification device) using a hygroscopic liquid such as a LiCl aqueous solution as a medium, and a refrigerant circuit system (air conditioning device) using a fluorocarbon gas or the like as a refrigerant. Therefore, there is a problem that the configuration of the device becomes complicated. Further, since the dehumidifier uses dehydration by the exhaust pump 36 to concentrate the moisture-absorbing liquid, the exhaust heat released by the condenser of the air conditioner cannot be used for the concentration, and the exhaust heat is wasted. There is a problem that the energy efficiency of the device is reduced.

It is to provide a method and an air conditioner.

First, a case will be described in which the LiCl aqueous solution is dehydrated using exhaust heat while storing cold in the cold storage panel 4 in the room R by using inexpensive nighttime electric power in the summer night. In this case, the moisture absorption / cooling circuit 1 is operated with the indoor fan 27 stopped, the refrigerant circuit 3 including the outdoor fan 24 and the second condenser 21 is operated, and the dehydration circuit 2 is operated. Then, the LiCl aqueous solution 8 in the tank 7 having a low concentration due to the water absorption by the dehumidifying operation in the daytime is cooled by the heat exchanger 11 while being pumped through the supply pipe 9a by the first pump 10, and the LiCl aqueous solution in the room R It flows into one tube 6. Here, since the indoor fan 27 is stopped, the cooled LiCl aqueous solution exchanges heat not with the room air but with the cold storage material 5 in the cold storage panel 4, and cold energy is stored in the cold 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 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 connected to Li
Only when the Cl aqueous solution reaches a predetermined temperature (for example, 60 ° C.) suitable for dehydration, the LiCl aqueous solution is fed into the second tube 16 at a high temperature and a high vapor pressure. Here, since the outside of the second tube 16 has a low vapor pressure and is ventilated with warm air by the outdoor fan 24, the moisture in the LiCl aqueous solution is:
Easily and in large quantities are discharged through the water vapor permeable membrane of the tube to the outside air. Then, the LiCl aqueous solution concentrated by dehydration returns to the tank 7 via the pipe 12. Thus, the LiCl aqueous solution 8 is simultaneously concentrated by the exhaust heat.

It only concentrates and restores its ability to absorb water. In the above embodiment, the temperature control valve 15
Is provided, only the LiCl aqueous solution that is heated in the heat exchanger 14 and has a predetermined temperature suitable for dehydration can be sent to the second tube 16, and there is an advantage that the dehydration in the second tube 16 is performed more effectively. . Further, a refrigerant circuit 3 is provided between the moisture absorption / cooling circuit 1 and the dehydration circuit 2, the evaporator 23 cools the cooling heat exchanger 11, and the first condenser 20 heats the heat exchanger 14 for heating. In addition to heating, the second condenser 21 with the outdoor fan 24 sends warm air to the second tube 16, so that the exhaust heat generated by cooling the cooling heat exchanger 11 is The heat exchanger 14 for heating and the LiCl aqueous solution can be effectively used for dehydration, and the energy efficiency of the air conditioner can be greatly improved, and the dehydration by hot air can be further promoted. Further, the evaporator 23, the heat exchanger 11, and the first condenser 2

ース空調の効果を高めることができる。Next, during the daytime in summer, the cold heat stored in the cold storage material 5 of the cold storage panel 4 is spontaneously released during the night before the day, and the air in the room R is radiatively cooled (so-called base air-conditioning), resulting in insufficient cooling. In some cases, 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. Circulate through the first tube 6 in the room R. Since the LiCl aqueous solution sent into the first tube 6 has a high concentration and a lower steam pressure than that of the room R, the moisture contained in the room air sent by the indoor fan 27 passes through the steam permeable membrane to the first tube. It is absorbed by the LiCl aqueous solution in the tube 6. This dehumidification removes the latent heat load, which accounts for a considerable proportion of the indoor cooling load, so that the effect of the base air conditioning can be enhanced.

事の簡素化を図ることができる。Further, when the sensible heat load is large during the daytime in summer, auxiliary cooling is performed to supplement the base air conditioning. That is, the compressor 18 of the refrigerant circuit 3 is operated while the indoor fan 27 is running, and the evaporator 23 cools the heat exchanger 11 for cooling the dehumidifying / cooling circuit 1. Then, the concentrated LiCl aqueous solution 8 circulated by the first pump 10 is cooled by the heat exchanger 11, flows into the first tube 6 in the room R, and flows into the first tube 6.
The cold heat of the iCl aqueous solution cools the indoor air stirred by the indoor fan 27. In other words, the room air can be actively cooled by using the LiCl aqueous solution as the refrigerant, and the cooling effect by the base air conditioning and the dehumidification can be further enhanced. In addition, since the dehumidification / cooling circuit 1 can dehumidify the room at any time, drainage equipment such as a drain hose is not required in the room, and the apparatus can be simplified, the cost can be reduced, and the installation work can be simplified. it can.

Also in this case, the first condenser 20 and the second condenser 21 can simultaneously utilize the exhaust heat to concentrate the LiCl aqueous solution 8 at the same time. In the above embodiment, since the indoor fan 27 is provided in the room R, the first tube 6
Of the LiCl aqueous solution 8 sent to the indoor fan 2
There is an advantage that when the operation is stopped, the air can be selectively supplied to the cold storage panel 4 and when the operation is performed, the air can be selectively supplied to the indoor air. In addition, since the refrigerant circuit 3 is provided with the on-off valves 25 and 26 and the bypass pipe 17h, when heating the LiCl aqueous solution to a predetermined temperature, the refrigerant is bypassed and the second condenser 21 is deactivated, and After the temperature reaches the temperature, the bypass is stopped, the second condenser 21 is operated, and the LiCl aqueous solution can be dehydrated, so that the LiCl aqueous solution can be more efficiently concentrated.
