Mixtures to replace R22 in high-temperature heat pumps.
Author(s) : GABRIELII C., VAMLING L.
Summary
The paper investigates various refrigerant mixtures to replace R22 that is currently used in several large (25 MW) turbo-compressor driven heat pumps to supply district heating in Sweden. The only commercially available alternative can be R134a, but its use could decrease the heating capacity by 35%. The aim of this work is to find a mixture giving a higher heating capacity than R134a. The paper screens about 2000 mixtures, containing two or more of R134a, R32, R143a and R125. The simulation results for the heat pump plant show that there are many mixtures that offer a considerably higher heating capacity than R134a, especially in summer-time.
