IMPROVED COOLING SYSTEM FOR A COMMERCIAL AIRCRAFT GALLEY

摘要

A cooling system for providing cooling air to cool an aircraft galley, comprises a housing including an enclosure with at least one vent for receiving air from the aircraft galley. A compressor motor is mounted to the housing for compressing a refrigerant coolant and a condenser is mounted to the housing for receiving and cooling the refrigerant coolant from the compressor motor. An expansion valve mounted to the housing receives cooled refrigerant coolant from the condenser, and at least one evaporator unit disposed within the housing receives refrigerant coolant from the expansion valve. There is also provided a system for returning warmed refrigerant coolant from the at least one evaporator unit to the compressor motor. An impeller connected to the housing for draws air from the aircraft galley into the housing of the cooling system through the at least one vent to circulate the air from the aircraft galley over the at least one evaporator to cool the air. A discharge receives cooled air from the impeller and discharges the cooled air into the aircraft galley.
