Abstract:
In a closed vapor compression refrigeration system having an expansion device and evaporator, a compressor, and a condenser, wherein liquid refrigerant is converted into gas in the expansion device and evaporator which is then fed to the compressor, wherein said gas is compressed and superheated, the superheated gas is then condensed in said condenser and converted back into cooler liquid refrigerant, a passive desuperheater for passively desuperheating said superheated gas before said gas is transmitted to said condenser comprising:a chamber having a first inlet for receiving said superheated gas, a second inlet for receiving cooler liquid refrigerant condensed by said condenser, said second inlet positioned below the outlet of said condenser to cause said liquid refrigerant to flow to said second inlet by the force of gravity, and an outlet that outputs said desuperheated gas for transmitting to said condenser, wherein said liquid refrigerant is caused to be mixed with said superheated gas in said chamber to reduce the temperature of said gas at said outlet.
