Exergy Analysis of Transcritical CO2 Air-Source Heat Pump with Honeycomb Gas Cooler

In order to build an efficient and energy-saving CO2 heat pump system improve the transfer efficiency of gas cooler, a novel honeycomb cooler with compact structure, high efficiency, pressure-bearing capacity was proposed in our previous work. To clarify components that need further optimization its performance, exergy analysis transcritical air-source is studied this paper. Based on second law thermodynamics, model each component established, irreversible loss analyzed. addition, degree energy clarified, possibility direction are pointed out. The results show 35.33% under nominal operating conditions, there lot room for improvement utilization. three largest destruction percentage compressor, throttle valve, evaporator 36.13%, 22.90%, 19.51%, respectively. These percentages main reasons large losses system.
