Patent abstract
A compressor system has a compression stage, a coolant circuit and a refrigerant circuit. The compression stage compresses ambient air and generates compressed air and heat. A coolant removes heat from the compression stage and the heat is transferred from the coolant to a refrigerant. A refrigerant expansion device is incorporated into the refrigerant circuit. The expansion device expands the pressurized refrigerant utilizing a rotary expander. Energy generated during refrigerant expansion is captured and used to drive components of the cooling system.
