Abstract:
An air conditioner, comprising an indoor unit (1), an outdoor unit (2), a gas pipeline (3), a liquid pipeline (4), a cooling branch (5) and a subcooling heat exchanger (6), and further comprising a first check valve (7) located on the gas pipeline (3) and a second check valve (8) on the cooling branch (5). Two ends of the cooling branch (5) are separately connected to the gas pipeline (3), and connection points thereof are located on two sides of the first check valve (7) respectively. Moreover, a part of the cooling branch (5) is arranged in the subcooling heat exchanger (6), and a part of the liquid pipeline (4) is arranged in the subcooling heat exchanger (6) for heat exchange. To a certain extent, the air conditioner may solve the problem of indoor noise caused by refrigerant flashing, and improve the comfort experience. Meanwhile, the effective gasification of the refrigerant in the cooling branch may also be ensured, which reduces the risk of liquid slugging and improves the operation reliability of the air conditioner.
