Performance Analysis of CO2 Air-source Heat Pump Heating System
Zhileng xuebao, 2020 The energy efficiency of conventional CO2 systems used for heating is low. Therefore, cascade and subcooling systems can be adopted to improve the performance of CO2 systems. In this study, the thermodynamic models of a baseline CO2 system (BASE), R410A vapor injection system, cascade system, indirect dedicated mechanical subcooling CO2 system (IDMS ...
