Abstract
The refrigerant in the high temperature circuit gets evaporated in trans-critical unit and passes through the HTC compressor. The refrigerant then passes through the HTC condenser where heat is released causing the refrigerant to cool. The refrigerant then passes through the HTC throttling valve, where the fluid expands losing temperature. In the presented research work, the two-stage CO2 refrigerants performance has been measured for cooling effect under transcritical system. A two-stage CO2 trans-critical unit for supermarket refrigeration has been built. COP values are calculated to be 22-72% greater over the particular ambient temperature range than for single stage compression. In both medium and low temperature belongings the COP improvement is greater given high ambient conditions.

Key-Words / Index Term
