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

摘要

The water of the liquid is disposed in contact with the outer peripheral surface of the water pipe 21 for circulating the inside of the water pipe 21 and the refrigerant piping 22a and 22b for circulating heat with water inside the water piping 21, and is disposed in the water piping 21. An agitating plate made of a plate having a spiral shape along the axis O1 of the water pipe 21 is provided.Therefore, a water refrigerant heat exchanger capable of improving the heat exchanging efficiency between the refrigerant in the refrigerant pipe and the water in the vicinity of the axis of the water pipe, and the heat pump device using the water refrigerant heat exchanger are obtained by suitably stirring water in the radial direction of the water pipe in the water piping.
