Problems of leak detection test to absorption chillers on-site

2010 
According to the national standard GB50274-98"code for construction and acceptance of refrigeration and air separation equipment installation engineering". Points out the problem that leakage rate does not meet 2. 03 Pa.mL/s in leak detection to the absorption chillers on site. It should be defined that definition of the leakage rate about halogen leak detection. Pressure holding time of the vacuum leak detection needs to be prolonged. These suggestions provide references for leak detection on site and making a new construction standard.
