Advantages of Helium Leak Detection
With the rapid development of social economy, air conditioners have been widely used in daily life, improving people’s living environment and comfort level. It is very important for air conditioners to be stable and reliable, especially to ensure that the air conditioner evaporator and condenser (i.e., air conditioner two devices) do not leak in order to ensure that it plays a normal role in refrigeration and heating, so it is necessary to ensure that it is not leaking on the production to reduce the air conditioner’s maintenance costs and customer complaints. National standard GB7725, the requirements of the air conditioner refrigeration system in the normal refrigerant charge, with a sensitivity of 1 * 10-6 Pa.m3 / s leak detector test does not leak, equivalent to a year of leakage is less than value = “2” unitname = “grams” > 2 grams / year. Therefore, the leakage control of air conditioning two devices is the air conditioning manufacturers face and pay attention to the problem. Early manufacturers of leak detection methods used by water bubble method, soap bubble method, halogen leak detection method, etc., with the intensification of competition in the air-conditioning market, these leak detection process has been far from adapting to market demand, and was gradually eliminated. In order to ensure the reliability, stability and high efficiency of air-conditioning leak detection, and at the same time to reduce labor costs, manufacturers have begun to focus on air-conditioning two-unit automated vacuum chamber helium detection process. As a professional helium detection team, we take the lead in the industry to explore and practice the automated vacuum chamber helium detection process for air conditioners.
