摘要： An apparatus and method for providing a refrigeration circuit and for effecting defrost are disclosed. Multiple outdoor heat exchangers (40, 50) are utilized to effect defrost of one of the outdoor heat exchangers while the other serves as an evaporator. In the refrigeration circuit (10) disclosed, the indoor heat exchanger (20) is not utilized during defrost and the outdoor heat exchangers (40,50) are separated such that one is defrosted while the other serves as an evaporator. The circuit (10) may then be reversed such that the non-defrosted outdoor heat exchanger is then defrosted while the other heat exchanger serves as an evaporator. This refrigeration circuit (10) allows for effective defrost of the outdoor heat exchangers (40, 50) without necessitating electric resistance heat nor the transfer of heat energy from the indoor air (20) to the outdoor heat exchangers (40, 50).
