Reliable, Cost-Effective Leak Detection

摘要

Manufacturers of refrigeration and air conditioning components and systems recognize that quality is as critical as the price and design of the product. The most critical quality factor is the tightness of the system. A miniscule leak, as small as a bacteria cell, can cause a loss of 1/4 ounce of refrigerant per year. But that is enough to render some air conditioning and refrigeration products inefficient or inoperable in a few years. For manufacturers, such defects can significantly increase warranty costs and degrade brand image. Consumers, businesses, and insti- tutional users also pay a heavy price for leakage: the U.S. Navy, for example, estimates that it spends $2.7 million each year replacing leaked refrigerants. In addition, refrigerant leakage needs to be limited due to the potential of ozone depletion and global warming. All components that will contain a refrigerant must be thoroughly and systematically tested to ensure they meet rigorous tightness standards. Several methods of leak detection are used in the HVACR industry.
