AIR CONDITIONING SYSTEM

摘要

To provide an air conditioner that eliminates discomfort (drafty feeling) that is produced as a result of conditioned air directly striking the human body and ensures heating comfort. An air conditioner (1) includes an indoor heat exchanger (6) that causes heat to be radiated with respect to air from a supercritical refrigerant and a fan (53) that generates an air flow with respect to the indoor heat exchanger (6). In the indoor heat exchanger (6) during heat radiation, the refrigerant is allowed to flow such that the refrigerant moves from a downstream side of the air flow closer to an upstream side thereof, and conditioned air that has been heated by the indoor heat exchanger (6) is blown out upward inside a room and is sucked in from below. The blowout temperature of the conditioned air is 45°C to 55°C, and the blowout velocity of the conditioned air is equal to or less than 2 m/s.
