ShareReplacement of R22 in heat pumps used for district heating.
Author(s) : GABRIELII C., VAMLING L.
Summary
In Swedish district heating systems several large (25 MW) turbo-compressor driven heat pumps using R22 are installed. The only commercially available alternative is R134a, but its use could decrease the heating capacity by 35%. The aim of the work is to find a mixture giving a better "economical performance" than R134a. The paper screens about 2000 mixtures, containing two or more of the components R134a, R32, R143a and R125.
