ABSTRACT:
A method and apparatus for defrosting the outside heat exchanger of a reversible vapor compression refrigeration (heat pump) system. The method and apparatus are particularly suited for use with smaller systems that employ a single fan motor to drive both the inside and outside heat exchanger fans. A heat storage apparatus is mounted in heat exchange relationship with the refrigerant piping between the system flow reversing valve and the inside heat exchanger. During operation in the heating mode, heat from the refrigerant is transferred to and stored in the heat storage apparatus. During operation in the defrosting mode, the refrigerant flow in the system is aligned as in the cooling mode but both fans are shut off. Heat stored in the heat storage apparatus is transferred to and used for defrosting the outside heat exchanger. The apparatus has little or no effect on system operation in the cooling mode.
