Abstract:
A multi-evaporator cooling system includes a compressor circuit that generates multiple levels of evaporating pressures, the circuit comprising at least one compressor configured to compress a refrigerant to a first pressure, a heat exchanger configured to receive the compressed refrigerant from the at least one compressor and cool the compressed refrigerant, a first evaporator circuit configured to receive the compressed refrigerant from the heat exchanger, expand the compressed refrigerant to a second pressure that is lower than the first pressure, and return the refrigerant to the compressor circuit, and a second evaporator circuit configured to receive the compressed refrigerant from the heat exchanger, expand the compressed refrigerant to a third pressure that is lower than the second pressure, and return the refrigerant to the compressor circuit.
