Abstract
In the paper, the high temperature vapour compressor based heat pump with a selection of working fluids, both perspective and ecological ones, is considered. Such system is not yet commercially available on the market and in author’s opinion it has significant potential for various applications. In the presented analysis it was assumed that the heat source has a temperature of 50oC and the temperature lift is 60, 80 and 100K respectively. Such temperature lift is a requirement for perspective applications. On the basis of obtained results the fluid working temperatures, heat rates, coefficient of performance of proposed solution as well as second law analysis have been determined. They confirm the potential for implementation in high temperature heat pumps in energy engineering area. Especially ethanol as working fluid seems to outperform other fluids.
