HEATING AND COOLING SYSTEM AND METHOD

摘要

HEATING AND COOLING SYSTEM AND METHOD A vapor compression heating/cooling system and method of operation having improved Coefficient of Performance and Capacity. Post-condenser liquid is cooled in a subcooler coil by a stream of air. One embodiment provides a warming machine or heat pump in which the condenser coil is within a volume to be warm and the evaporator coil is on the outside exposed to ambient air. A stream of ambient air is pumped in heat exchange relationship with the subcooler coil to recover and expel heat from the coil into the volume. Where the volume comprises the interior of a house or other building structure the stream of air from the subcooler creates an over pressure within the volume to minimize infiltration of ambient air. In another embodiment the system is employed for refrigerating a volume such as a reefer trailer or other mobile compartment. The evaporator coil is within the compartment and the condenser coil is outside the compartment exposed to ambient air. A stream of air from the compartment is directed by a duct in heat exchange relationship with the subcooler coil and thence to ambient for expelling heat from the post-condenser liquid.
