Transcritical Co2 Cycle with and without Suction Line Heat Exchanger at High Ambient Temperatures

[EXTERNAL] Abstract:
Global warming and ozone depletion potential of chemical refrigerants have motivated to develop the refrigeration systems with natural refrigerants. Transcritical Co2 refrigeration cycle losses its performance at higher ambient temperature due to lower critical temperature of Co2. This paper discusses the comparative analysis of the transcritical cycle with and without suction line heat exchanger. At higher ambient conditions, the use of suction line heat exchanger improves the cycle performance by 2 to 4%…
