Water refrigerant heat exchanger and heat pump device equipped with water heat exchanger

摘要

The water-refrigerant heat exchanger includes a water pipe through which water flows and a refrigerant pipe through which refrigerant flows, and performs heat exchange between water flowing through the water pipe and refrigerant flowing through the refrigerant pipe. The refrigerant pipe of the water refrigerant heat exchanger is spirally wound around the outer peripheral surface of the water pipe. Moreover, the air piping which contains air inside is arrange | positioned in the area | region where refrigerant | coolant piping was wound among the water piping of a water refrigerant | coolant heat exchanger. The heat pump device exchanges heat between the water refrigerant heat exchanger configured as described above, a compressor that compresses the refrigerant, a decompression device that decompresses the refrigerant, and the refrigerant decompressed by the decompression device and the outside air. An evaporator.
