Abstract
A refrigerant pump system wherein the outdoor coil is larger than the indoor coil to provide for efficient operation when the system is in a cooling mode. A refrigerant reservoir is mounted in a refrigerant line that connects the two coils during a heating mode which is arranged to collect liquid refrigerant, thus preventing the outdoor coil from becoming overcharged with refrigerant during the heating process. Efficient operation of the system is thus maintained during both heating and cooling without the need for expensive equipment to regulate the flow of refrigerant between the heat exchanger coils.
