It is found that the match between compressors and condensers is inconsequence under part-load conditions. It results in a low condensing pressure and high energy consumption. The energy saving is 5.43 kW from the field testing under part-load conditions if the condensing pressure is reasonably controlled. Optimal control of condensing pressure can save energy...
