HEAT RADIATION AND CIRCULATION SYSTEM OF AIR CONDITIONER

摘要

Provided is a heat radiation and circulation system of an air conditioner, which adopts a flat-pipe micro-passage aluminium radiator (6) and comprises a compressor (1). An exhaust pipe of the compressor (1) is connected to a four-way directional control valve (2), the four-way directional control valve (2) is connected to an outdoor heat exchanger (4), the outdoor heat exchanger (4) is connected to an indoor heat exchanger (10) via an electronic expansion valve (11), the indoor heat exchanger (10) is connected to a shut-off valve (3), the shut-off valve (3) is connected to an air suction pipe of the compressor (1) via the four-way directional control valve (2), the air suction pipe of the compressor (1) is connected to the compressor (1) via a gas-liquid separator (9), a refrigeration cycle branch is arranged on the air suction pipe, the refrigeration cycle branch comprises a branch electromagnetic valve (5), the branch electromagnetic valve (5) is connected to the flat-pipe micro-passage aluminium radiator (6), and a temperature sensor (8) is arranged on the flat-pipe micro-passage aluminium radiator (6); an air suction electromagnetic valve (7) is also arranged on the air suction pipe; and the air suction electromagnetic valve (7) is connected in parallel to the branch electromagnetic valve (5). The present invention can improve the heat radiation efficiency, recover the heat emitted from an air-conditioning module, and ensure the operating stability of an air-conditioning unit.
