Abstract: A heat source unit for a heat pump having a refrigerant circuit, the heat source unit having: an outer casing including a bottom plate; and a compressor assembly accommodated in the outer casing, the compressor assembly including a compressor of the refrigerant circuit of the heat pump including a compressor housing, a support plate supporting the compressor, the support plate being mounted via dampers to the bottom plate, and a compressor casing enclosing the compressor and the compressor housing. A damping mechanism is arranged between the compressor and the support plate, and the compressor casing is fixed to the support plate out of contact with the compressor housing.

Abstract: An outdoor unit for a heat pump includes a refrigerant circuit, the outdoor unit including a compressor, a discharge pipe of the refrigerant circuit connected to a discharge side of the compressor, a bottom plate, the bottom plate having a base and an outer flange protruding upward from an outer edge of the base, a heat source heat exchanger supported on the bottom plate, a liquid refrigerant pipe of the refrigerant circuit connected to the heat source heat exchanger, and a defrosting bypass pipe connected at one end to the discharge pipe and at the opposite end to the liquid refrigerant pipe, the defrosting bypass pipe being arranged between an inner side of the flange and an outer side of the heat source heat exchanger.

Abstract: Provided is a temperature-adjusting fluid supply apparatus that causes a fluid for temperature adjustment to be circulated between a heat exchanger that transfers heat supplied from a refrigerant to the fluid, and an object to be adjusted for temperature that uses the heat of the fluid, the temperature-adjusting fluid supply apparatus being able to prevent the fluid from freezing. A temperature-adjusting fluid supply apparatus is provided with a heat exchanger that transfers heat supplied from a refrigerant to a fluid for temperature adjustment, a supply tube through which the fluid flows from the heat exchanger toward an object to be adjusted for temperature, a return tube through which the fluid returning from the object to be adjusted for temperature flows, a flow rate adjustable pump, a flow sensor, a flow switch, a temperature sensor, and a control part.
