Performance of the very high-temperature heat pump with low GWP working fluids

Abstrakt

Traditional heat pumps are a very attractive pro-ecological solutions for a number of applications, including providing of heating or heat recovery from industrial processes. The application range of heat pumps could be greatly enlarged when the operating temperature would be increased to 130-150°C and/or the temperature lift can be increased to 50-100 K. In the paper, the very high temperature vapour-compressor based single stage and cascade heat pumps with a number of working fluids are presented. In author's opinion, it has a significant potential for various applications. In described analysis it was assumed that that heat source has a temperature of 50°C, whereas the condensation temperature is 130°C. On the basis of obtained results the working fluid temperatures, heat rates and the coefficient of performance of proposed solution have been determined.
