Abstract
A cooling energy generator with a cooling energy accumulator comprises a refrigerant, absorbent liquid, and a container having a first chamber receiving the absorbent liquid, a second chamber receiving the liquid refrigerant and a vapor passage communicating with a space over the absorbent liquid in the first chamber and with a space over the liquid refrigerant in the second chamber. The absorbent liquid is sprayed in the first chamber, and the absorbent liquid is cooled during an accelerated cooling operation. The absorbent liquid is heated during the cooling energy accumulation operation, and liquid refrigerant is sprayed in the second chamber during the accelerated cooling operation and during the normal cooling operation. An air conditioning heat exchanger supplies the cooling energy to a cooling device for air conditioning, and a heat pump is provided. The cooling energy generator with the cooling energy accumulator continues to generate cooling energy for normal air cooling without any additional device even when the refrigerant is not absorbed by the absorbent because the refrigerant is circulated in the second chamber to generate the normal cooling energy.
