The invention discloses an air-conditioning system with refrigerant reclaiming function. The air-conditioning system comprises a refrigerating cycle system, wherein the refrigerating cycle system at least consists of a compressor, a condenser, an evaporator and an electronic expansion valve or a throttling capillary; when the air-conditioning system enters a refrigerant reclaiming work mode, a liquid pipe connected between an indoor unit and an outdoor unit of an air-conditioner is cut off; then, the air-conditioning system automatically performs refrigerating operation, and for the air-conditioning system, the indoor unit of which the electronic expansion valve is arranged in, the electronic expansion valve in the indoor unit is opened at the same time; and after the refrigerant is totally reclaimed to the outdoor unit from the indoor unit, an air pipe connected between the indoor unit and the outdoor unit is cut off, the air-conditioning system is controlled to stop, and the refrigerant reclaiming process is finished. Because of the refrigerant reclaiming function, the air-conditioning system is convenient for maintenance personnel to safely and reliably reclaim the refrigerant, avoids the problems of incomplete refrigerant reclamation or compressor fault and the like, reduces the discharge of the refrigerant, and reduces the maintenance cost.
