Abstract (en)
Provided is an indoor unit (200) provided with a fan (8), a casing (7) which accommodates the fan (8), and a heat exchanger (60) provided in the casing (7) and disposed to surround the fan (8). The heat exchanger (60) has a plurality of fins (17) which are arranged in the circumferential direction with surfaces facing each other, and a plurality of refrigerant pipes which pass through the plurality of fins (17) and extend along the circumferential direction. The plurality of refrigerant pipes has a first pipe line (34A) through which a refrigerant flows in a first circumferential direction (33A) which is one direction of the circumferential direction, and a second pipe line (34B) through which a refrigerant flows in a second circumferential direction (33B) opposite to the first circumferential direction (33A). A first refrigerant inlet (36A) configured to introduce the refrigerant from the outside of the heat exchanger (60) toward the first circumferential direction (33A) is provided at a starting point of the first pipe line (34A), and a second refrigerant inlet (36B) configured to introduce the refrigerant from the outside of the heat exchanger (60) toward the second circumferential direction (33B) is provided at a starting point of the second pipe line (34B).
