Research and Applications of Pressure Test for Vapor Compression Refrigeration System[J]. Journal of refrigeration, 2011, 32(1). DOI: 10.3969/j.issn.0253-4339.2011.01.046.
The observation of leak detection on site for vapor compression refrigeration system showed that foamy leaks might be found by foamy test
even when maintaining pressure test met the requirement of national standard GB50274-98 code for construction and acceptance of refrigeration and air separation equipment installation engineering.To address this issue
different effects of foam and maintaining pressure test
as well as leakage rate criterion for maintaining pressure test in GB50274-98 were studied.It is sho...
