Ice making machine with cool vapor defrost

摘要

An ice making machine (2) has a water system, including a pump, an ice-forming mold and interconnecting lines therefore; a refrigeration system (100), including a compressor (112), a condenser (114), an expansion device (126), an evaporator (128) in thermal contact with the ice-forming mold, and a receiver (118). The receiver (118) has an inlet (120) connected to the condenser (114), a liquid outlet (122) connected to the expansion device (126) and a vapor outlet (134) connected by a valved passageway to the evaporator (128). <IMAGE>
