Air/water heat exchange apparatus

摘要

An object is to provide a cost saving and energy efficient air/water heat exchange apparatus by utilizing parts of an outdoor unit designed for a separate type air conditioner, and thus utilizing existing plant and equipment. The air/water heat exchange apparatus includes the outdoor unit that is separated by the separator into the fan room and the machine room. The fan room includes an air-refrigerant heat exchanger that exchanges heat between air and the refrigerant, and the fan that sends the air to the air-refrigerant heat exchanger. The machine room includes the compressor that compresses the refrigerant, the plate heat exchanger that exchanges heat between the refrigerant and water, the electronic expansion valves, and the accumulator that accumulates the refrigerant. The outdoor unit contains the closed refrigerant circuit, which includes the compressor, the plate heat exchanger, the electronic valves, the air-refrigerant heat exchanger, and the accumulator.
