とを防止するのは不可能であつた。 Conventionally, in order to effectively use electricity for air conditioning, surplus electricity at night is used to operate a vapor compression refrigeration cycle to cool and store cold storage material, and the air is released to cool during the day. There is a harmonizer. However, when using a cold storage material that uses sensible heat, it is necessary to make the cold storage tank very large, and even when using a cold storage material that uses latent heat, there are very few suitable cold storage materials and they are expensive. Furthermore, during solidification, a supercooling phenomenon occurs, which reduces the efficiency of the refrigeration cycle, and has various other drawbacks. Also,
In such a device, it has been impossible to prevent heat from entering the cool storage material from the surrounding air and reducing the amount of cool storage.

A liquid refrigerant tank 5 for storing condensed refrigerant is provided between the condenser 2 and the capillary tube 3.
Further, between the evaporator 4 and the compressor 1, an adsorption tank 7 containing an adsorbent 6 for adsorbing the evaporated refrigerant.
is provided. Note that 8 is an on-off valve on the inlet side of the liquid refrigerant tank 5, and 9 is an on-off valve on the outlet side. Further, 10 is a condenser blower, and 11 is a condenser blower.

ンク７を通過し、再び、圧縮機１に吸入される。 In the above configuration, during normal cooling operation, the high-temperature, high-pressure gas refrigerant discharged from the compressor 1 radiates heat to the outside air blown by the condenser blower 10 in the condenser 2, and is condensed and liquefied. Thereafter, it passes through the inlet side on-off valve 8, the liquid refrigerant tank 5, and the outlet side on-off valve 9, is depressurized and expanded to the evaporation pressure in the capillary tube 3, and flows into the evaporator 4. Here, the indoor air blown by the evaporator blower 11 absorbs heat, evaporates, and performs a cooling action, and then passes through the adsorption tank 7 and is sucked into the compressor 1 again.

費しない冷房運転が可能となる。 Next, when there is surplus power such as at night and cooling is not required, the inlet on-off valve 8 is opened, the outlet on-off valve 9 is closed, and the compressor 1 and condenser blower 10 are operated. That is, the refrigerant adsorbed by the adsorbent 6 of the adsorption tank 7 is sucked out and compressed by the compressor 1 to become a high temperature and high pressure gas refrigerant, and is led to the condenser 2, where the condenser blower 1
Air is blown by 0. After radiating heat to the cold outside air at night and condensing into liquid, it passes through the inlet opening/closing valve 8,
The high-pressure liquid refrigerant is stored in the liquid refrigerant tank 5. When the liquid refrigerant tank 5 is almost filled with high-pressure liquid refrigerant, the operation is stopped and preparations are made for the next cooling operation. In this state, during the day, etc.
During cooling operation, which requires power saving, the inlet on-off valve 8 is closed, the outlet on-off valve 9 is opened, and the evaporator blower 11 is operated. That is, in the above-described operation, the high-pressure liquid refrigerant stored in the liquid refrigerant tank 5 passes through the outlet opening/closing valve 9, is depressurized and expanded to the evaporation pressure in the capillary tube 3, and flows into the evaporator 4. Here, the indoor air blown by the evaporator blower 11 absorbs heat, evaporates, and performs a cooling action, and then flows into the adsorption tank 7 and is adsorbed by the adsorbent 6. In this way, cooling operation that consumes almost no power is possible.

ものである。 As is clear from the above description, the air conditioner of the present invention includes a liquid refrigerant tank having on-off valves at the inlet and outlet, respectively, between the condenser and the throttle device, that is, the capillary reach tube.
This system is characterized by an adsorption tank containing a refrigerant adsorbent between the evaporator and compressor, so it can be used efficiently at night when there is surplus electricity, the outside air is cold, and air conditioning is not required. By frequently operating the compressor, high-pressure liquid refrigerant is stored in a liquid refrigerant tank, and during peak power hours during the day, the high-pressure liquid refrigerant stored in the liquid refrigerant tank can be used to perform cooling operation with very low power consumption. It is possible. In addition, since operation can take advantage of the low outside temperature at night, the condensing pressure can be kept relatively low and the power consumption of the compressor can be reduced.Furthermore, the liquid refrigerant tank is cooled by naturally dissipating heat into the surrounding air. As a result, the cooling capacity per unit amount of refrigerant circulation, that is, the refrigeration effect, increases, so there is no need to insulate the cold storage tank or use special cold storage materials like in conventional cold storage air conditioners, resulting in high efficiency. This allows for cooling operation that allows for effective use of electricity.
