METHOD AND DEVICE FOR IMPROVING EFFICIENCY OF HEAT PUMP USING ALTERNATIVE FOR CHLOROFLUOROCARBON AS REFRIGERANT

摘要

PROBLEM TO BE SOLVED: To provide a technological means capable of improving energy efficiency (coefficient of performance) of a heat pump using, as a refrigerant, an alternative for chlorofluorocarbon (HCFC and HFC) used for an existing air conditioner, refrigerator, freezer or the like by inexpensive and simple work.;SOLUTION: Silicon carbide powder is attached to refrigerating piping of the heat pump using the alternative for chlorofluorocarbon as the refrigerant, in particular piping between a heat release side heat exchanger (condenser) and an expansion valve, particularly preferably, copper piping immediately before the expansion valve. The silicon carbide powder is mixed with a coating material serving as a binder and is coated, or can be attached by filling the silicon carbide powder in a container and attaching the container to the refrigerant piping.;COPYRIGHT: (C)2011,JPO&INPIT
