IIR documentSummary
Some fluids that can be used in geothermal heat pumps are analysed theoretically in the paper. Principles to be used when choosing working fluids for high temperature heat pumps are also provided. It was found that a R22/R141b mixture is one of the potential fluids. The experimental results show that the coefficient of performance reaches a maximum when the molar component of R22 is about 75%.
