Abstract

Synthetic refrigerants such as CFCs and HCFCs are harmful to the ozone and could cause greenhouse effect. Refrigerant alternatives research is very urgent. CO₂ as a natural working fluid has zero ODP and its GWP=1, is receiving more and more attention in the refrigeration field. Transcritical CO₂ refrigeration cycle is presently an important aspect of natural refrigerant alternatives research. In this paper, the transcritical CO₂ refrigeration cycle system is experimental studied, influence of external heat source on system performance is analyzed. The experimental results show that cooling water temperature, chilled water flow and temperature have a great impact on system performance, while the cooling water flow has no obvious effect in the experimental device.
