Transcritical carbon dioxide heat pump systems: A review
نویسندگان
چکیده
Carbon dioxide is a safe, economic and environmentally sustainable refrigerantwhich can be used in heat pump and refrigeration systems. Research into the performance and benefits of a transcritical heat pump cycle using carbon dioxide began in the early 1990s. Theoretical and experimental research, as well as commercial system development, has improved transcritical system performance to a level similar to

Optimization of a transcritical CO2 heat pump cycle for simultaneous cooling and heating applications
Energetic and exergetic analyses as well as optimization studies of a transcritical carbon dioxide heat pump system are presented in this article. A computer code has been developed to obtain sub-critical and super-critical thermodynamic and transport properties of carbon dioxide. Estimates for irreversibilities of individual components of the system lead to possible measures for performance im...

متن کاملSimulation on the Performance of Carbon Dioxide and HFC-125 Heat Pumpsfor Medium-and High-Temperature Heating
In order to compare the performance of the carbon dioxide and HFC-125 heat pumps for medium-and high-temperature heating, both heat pump cycles were optimized using a simulation method. To fairly compare the performance of the cycles by using different working fluids, each cycle was optimized from the viewpoint of heating COP by two design parameters. The first is the gas cooler exit temperatur...
