コン用熱交換器。[Claims for Utility Model Registration] (1) Heat exchanger tubes having spiral grooves on their inner surfaces are arranged in a meandering manner to boil the refrigerant flowing in one direction during cooling, and the refrigerant flowing in the opposite direction during heating. In a heat exchanger for a heat pump air conditioner that condenses water, the spiral groove is arranged at an angle of 60° to 90° with respect to the tube axis on the upstream side in the refrigerant flow direction during cooling.
A heat exchanger for a heat pump air conditioner, characterized in that the heat exchanger is formed at an angle of 0° to 30° with respect to the tube axis on the downstream side. (2) The heat exchanger for a heat pump air conditioner according to claim 1, wherein when the heat transfer tube is meandered in a vertical plane, the upstream side is provided at a higher position than the downstream side.
