Abstract
A cooling system is provided and includes a compressor, an expansion valve, a gas cooler through which a refrigerant received from the compressor passes toward the expansion valve in a supercritical state, an evaporator interposed between the expansion valve and the compressor and a vapor sorption subcooling system. The vapor sorption subcooling system includes a desorber disposed to remove heat from refrigerant flowing from the gas cooler toward the expansion valve.
Claims20
A cooling system, comprising:
- a compressor;
- an expansion valve;
- a gas cooler through which a refrigerant received from the compressor passes toward the expansion valve in a supercritical state;
- an evaporator interposed between the expansion valve and the compressor;
- and
- a vapor sorption subcooling system comprising a desorber disposed to remove heat from refrigerant flowing from the gas cooler toward the expansion valve.
A vapor absorption subcooling system, comprising:
- a desorber in which a first refrigerant is cooled;
- a subcooling compressor, which is receptive of subcooling refrigerant from the desorber;
- an absorber for subcooling refrigerant absorption by an absorbent;
- a subcooling gas cooler through which the subcooling refrigerant received from the subcooling compressor passes toward the absorber in a supercritical state;
- and
- a pump configured to pump at least the absorbent from the desorber to the absorber.
A vapor adsorption subcooling system, comprising:
- a desorber in which a first refrigerant is cooled;
- a subcooling compressor, which is receptive of subcooling refrigerant from the desorber;
- an adsorber disposed in parallel with the desorber for subcooling refrigerant adsorption by an adsorbent;
- and
- a subcooling gas cooler through which the subcooling refrigerant received from the subcooling compressor passes toward the adsorber and the desorber in a supercritical state.
