The development of the energy-saving technology by the composition control of R407C.

Author(s) : KUSAKA M., NAKATANI K., TAKATANI T.

Summary

The purpose of the study is to develop a higher performance refrigeration system with R407C (R32-R125-R134a: 23-25-52 wt%), using a technique of capacity control by varying the zeotropic refrigerant composition. Then, the authors applied this rectification system to a packaged air conditioner. It was confirmed that the annual SEER increased about 25% in the comparison with an ordinary low-cost system using a constant-speed compressor. This performance is comparable to that of the high-cost system with a variable-speed compressor.
