Abstract

It is well known that the isothermal compression is an ideal process to consume least power for compressor. The isothermal compression can't be really reached, but can be approached by decreasing the discharge temperature during compression. For this purpose, a cooling system has been built in the paper. Firstly, an innovative circulation system has been built to absorb the heat generated by compression, which is segregated from the refrigeration circulation system. The principle and the structure are introduced. Then, the experimental has been conducted. Based on the experimental, the following results has be obtained: The cooling capacity increased by 1.3%; for the experimental condition, discharge temperature of the gas reduced by 10℃, input power reduced by 4.1%, and COP increased by 5.2%.
