Abstract: In this paper, a helium recovery and purification device for air-conditioning leak detection equipment is studied. The results show that the device can effectively maintain the purity of helium in air-conditioning leak detection equipment above 80%. The helium usage of the process is about 6.7 m3 per day, which is less than the helium emission of the system due to low purity when the process is not used. Considering the actual use of the enterprise, the helium emission from the system is about 7 m3 per day. According to the economic requirement of the device, the direction of the follow-up process optimization of the device is put forward.

Key words: air-conditioning helium leak detection, helium recovery, helium purification
