    • Study of Refrigerants for Heat Pumps in Colder Climate 

      Eriksen, Nils Eivind (Master thesis; Mastergradsoppgave, 2014-06-01)
      The aim for the thesis is to look at the performance of natural refrigerants in heat pumps while operating in a colder climate. The advantage of using natural refrigerants is that they have significantly lower global warming potential (GWP) in comparison to the synthetic refrigerants i.e. hydro fluorocarbons (HFC) and hydro chlorofluorocarbons (HCFC). Natural refrigerants are becoming common to use ...
