分体式空调制冷剂的回收方法：接通电源，让空调制冷。用扳手缓慢关闭室外机高压阀，使室外机的制冷剂不再流入室内机。原来滞留在室内机的制冷剂由压缩机抽回室外机，大约经30~60秒后，制冷剂即可回收干净。然后再关闭室外机低压阀，最后断开空调电源。
Recovery method of refrigerant for split air conditioner: turn on the power and let the air conditioner cool. Close the high-pressure valve of the outdoor unit slowly with a wrench, so that the refrigerant of the outdoor unit will not flow into the indoor unit. The refrigerant that was detained in the indoor unit is pumped back to the outdoor unit by the compressor. After about 30-60 seconds, the refrigerant can be recovered. Then close the low-pressure valve of the outdoor unit, and finally disconnect the power supply of the air conditioner.
