| Abstract: | To solve the problems that the energy consumption and initial investment of the test equipment of positive displacement compressor is high,a kind of improved test equipment was introduced.The liquid flow counter method was applied to measure the refrigerating capacity.Results show:(1)the control precision of the improved test equipment is high;(2)the relative error of the improved test equipment is 1.5%.Compared with the room-type calorimeter,the energy consumption and initial investment of the improved test equipment decreased by 72.2% and 60%,respectively. |
