홈페이지논문 초록 (Abstract)
One major breakthrough in the field of heating, ventilation and air conditioning has beenthe development of heat pumps. Heat pump syste ms offer economic alternatives forrecovering heat from different sourc es for use in various industrial, commercialandresidential applicatio ns. In recent years, the heat pump has been tipped to have a very goodpotential for hot water production. This paper investigat ed the performance of a vaporinjection heat pump with the variation of sub-cooler capacity at heating mode. The heatingcapacity of the vapor injection heat pump slightly increased with an increment of sub-cooler capacity, while COP didn’t increase continuously. The 20% capacity ofsub-cooler comparing with system capacity could be used as a standard to selectsub-cooler capacity.
