<p>A refrigerant heat pump system (10) wherein the outdoor coil (16) is larger than the indoor coil (15) to provide for efficient operation when the system (10) is in a cooling mode. A refrigerant reservoir (35) is mounted in a refrigerant line that connects the two coils (15,16) during a heating mode which is arranged to collect liquid refrigerant, thus preventing the outdoor coil (16) 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 (15,16).</p> |
