Abstract
A cascade heat recovery system connects an evaporator from a heating unit to a recovery condenser of the cooling unit, where the recovery condenser is different from a cooling condenser of the cooling unit, and/or connects the evaporator of the heating unit to the cooling loop of the cooling unit, for example in fluid communication with the evaporator of the cooling unit. Both configurations allow the heating unit to be isolated or decoupled from the heat rejection circuit on which the cooling condenser runs. The use of either or both configurations, depending on the operating conditions, can use heat rejected by the evaporator of the cooling unit to be available to the heating unit, so as to provide lift to the heating unit and improve its operating efficiency.
