PROBLEM TO BE SOLVED: To provide a heat pump heat source machine improving ventilation performance by reducing interference of ventilation due to a coupling.SOLUTION: The heat pump heat source machine includes a water heat exchanger 3 disposed on a substrate and carrying out heat exchange of a refrigerant and water, a water heat exchanger cover 4 covering the water heat exchanger 3, an air heat exchanger 2 carrying out heat exchange of the refrigerant and air and provided in a back face side of the substrate, a blower fan 5 passing air through the air heat exchanger 2, a blower fan mounting member 6 fixing the blower fan 5, and the coupling 7 supporting the blower fan mounting member 6 and the air heat exchanger 2. The blower fan mounting member is disposed on an upper part of the water heat exchanger cover via the coupling, the air heat exchanger is disposed on the substrate via the coupling, and an opening 8a (8b) is provided in one part of the coupling facing the air heat exchanger. |
