Abstract

See full text

Systems and methods are disclosed that may include recovering heat from a generator to defrost the heat exchanger by passing a heat transfer fluid from the generator through a recovery heat exchanger that is configured to promote heat transfer between the heat transfer fluid and a refrigerant flowing therethrough, reducing a restriction of the refrigerant, reducing an airflow through the heat exchanger, and delivering the heated refrigerant to the heat exchanger. Systems and methods may also include recovering heat from an exhaust of the generator to deter the formation of frozen condensate on the outdoor heat exchanger by diverting at least a portion of a hot exhaust fluid discharged by the generator onto the outdoor heat exchanger.
