Abstract (en)
In a heat pump water heating system (1) including a refrigerant circuit (30) having a compressor (11a), a four-way valve (11b), a water heat exchanger (11c), an expansion valve (11d), and a heat source end heat exchanger (20a) being piping-connected in series, and a hot water storage tank (13) connected to a water circuit (12) of the water heat exchanger (11c) for supply and storage of hot water generated at the water heat exchanger (11c), at least the compressor (11a), the four-way valve (11b), and the water heat exchanger (11c) constituting the refrigerant circuit (30), and the hot water storage tank with water circuitry connected to the water heat exchanger (11c) are accommodated together in a single casing to constitute a main unit (10), and the heat source end heat exchanger (20a) is configured to separate from the main unit (10) by a piping connection.
