Abstract

A swimming pool or spa heat pump operable in cooling and heating modes, along with a method of operating same is disclosed. The heat pump includes a compressor, first and second heat exchangers, refrigerant charge compensator, and at least one means for lowering the pressure of refrigerant provided to the first and second heat exchangers. The first heat exchanger is configured to transfer thermal energy to and/or extract thermal energy from a first fluid, and the second heat exchanger is configured to transfer thermal energy to and/or extract thermal energy from pool or spa water. The refrigerant charge compensator is configured to reduce an amount of active refrigerant charge in circulation in the heat pump when the heat pump is operated in the cooling mode and increase the amount of active refrigerant charge in circulation when the heat pump is operated in the heating mode.
