Konferensbidrag (offentliggjort, men ej förlagsutgivet), 1991

Results from measurements of COP and capacity of a one-stage heat pump are presented. As working fluids CFC 12 and two compositions of the HCFC22/HCFC142b have been used. The COPs of the mixtures are the same as those of CFC12. The mixture containing 60 Mole-% HCFC22 gave the same capacity as that of CFC12.
