A device for recovery of refrigerant from a sealed heat transfer system includes a refrigerant conduit formed in the device for guiding a flow of refrigerant from the heat transfer system to a refrigerant outlet of the device, a refrigerant inlet to the refrigerant conduit. The refrigerant inlet can be provided in a surface of the device. The device can include a tool for providing an opening between an opening area of a part of the heat transfer system and the refrigerant inlet, a driver to drive a movement of the tool in order to provide the opening in the opening area. The device further includes a first gas conduit formed in the device for guiding a flow of gas between a first internal gas opening being provided in a surface of the device and a first external gas opening of the device.

The present application provides an air conditioner and an automatic refrigerant recovery method. The air conditioner comprises an indoor unit, an outdoor unit, and a recovery assembly. The recovery assembly comprises a detection module, a control module, and an execution module; the detection module is used for acquiring air conditioner operation data and refrigerant detection data of an indoor space; the execution module is used for controlling connection / disconnection of pipes of the air conditioner and achieving recovery of a refrigerant from the indoor unit to the outdoor unit; and the control module is communicatively connected to the detection module and the execution module. In the air conditioner and the automatic refrigerant recovery method provided by the present application, by means of the structure of the air conditioner itself, the refrigerant is recovered to an outdoor heat exchanger for storage, thereby simplifying the structures of automatic refrigerant recovery apparatuses, and thus lowering the design difficulty, installation cost and maintenance cost of the automatic refrigerant recovery apparatuses.

The first recovery device (16) recovers the compressed and condensed refrigerant generated by compressing and condensing the air-conditioning refrigerant. The adsorption device (418) includes an adsorption module (468). The adsorption module (468) has an adsorbent (350) that adsorbs the gas component (423) of the air-conditioning refrigerant in the mixed gas (22) composed of the gas component (423) of the air-conditioning refrigerant and the non-condensable gas (26) contained in the inside of the first recovery device (16) that recovered the compressed and condensed refrigerant. The desorption device (19) desorbs the gas component (423) of the air-conditioning refrigerant adsorbed to the adsorbent (350) and accumulates the desorbed gas component (423) of the air-conditioning refrigerant.
