ABSTRACT:
Energy recovery systems for cold storage warehouses refrigerated by mechanical refrigeration apparatus coacting with a energy recovery unit including a turbine driving an electromotive generator. The cogenerator turbine is driven by the kinetic energy extracted from refrigerant flowing through a first conduit system connecting the compressor, evaporators and condenser of the refrigeration or by the kinetic energy extracted from a coolant being pumped through a second conduit system independent of the first conduit system to cool the compressor as it becomes heated during compression of refrigerant from a vapor phase to a liquid phase during the refrigeration cycle. The extraction of the kinetic energy of the refrigerant flow or coolant flow and the heat generated by the compressor during the refrigerant compression phase represents useful work obtained from the energy recovery system from available surplus energy that otherwise would be wasted.
