PERFORMANCE INVESTIGATION OF THE ROLLING PISTON TYPE REFRIGERATING ROTARY COMPRESSOR WITH R22

摘要

In this paper, the some properties of R12 and R22 have been compared. The experiment of thermal performance of the compressor has been carried out at various evaporating and condensing temperature. The cuves of main performance parameters have been obtained. The analysis far the experimental data shows that there are a particular corresponding relationship between the E.E.R. and the pressure ratio and a linear relationship between the volumetric efficiency and the pressure ratio. Moreover, the performance of the compressor applied to the lower evaporating temperature has been discussed.
