Abstract

A heat pump includes a refrigerant circuit for circulating a refrigerant and including a compressor, a heat source heat exchanger, an expansion valve, and an intermediate heat exchanger, a heat medium circuit for circulating a heat medium comprising a pump and the intermediate heat exchanger, an outdoor unit including an outdoor unit casing housing at least the heat source heat exchanger, the compressor, and the expansion valve, an indoor unit comprising an indoor unit casing housing at least the pump, and a heat exchanger unit including a container housing the intermediate heat exchanger. The heat source heat exchanger, the compressor, the expansion valve, and the intermediate heat exchanger are connected via a refrigerant piping, and the intermediate heat exchanger and the pump are connected via a heat medium piping. The container of the heat exchanger unit is separate from the indoor unit casing and the outdoor unit casing.
