Performance simulation of single-evaporator domestic refrigerators charged with pure and mixed refrigerants

International Journal of Refrigeration, 1991
Abstract A computer simulation of single-evaporator domestic refrigerators charged with pure and mixed refrigerants has been performed in an attempt to screen out the best substitutes for R12. In simulating a steady-state thermal system, both successive substitution and the Newton-Raphson methods were employed independently and yielded the same ...

Refrigerant mass charge distribution in a domestic refrigerator, Part I: Transient conditions

Applied Thermal Engineering, 2006
Experimental results are presented of the refrigerant mass charge distribution in a steadily cycling domestic refrigerator. In detail it is shown how the charge is displaced at compressor start-up and shut-down. At start-up it was found that the charge was temporarily displaced towards the condenser before returning to a steady state distribution in ...

Refrigerating machine operating characteristics under various mixed refrigerant mass charges

International Journal of Refrigeration, 2008
Abstract This paper reports the results of experimental investigation of a low-temperature Joule–Thomson refrigerating machine, working by use of a non-azeotropic mixture of refrigerants and with a single-stage hermetic compressor. The temperature, hydraulic and power performance of the machine are determined experimentally in relation to the mixed ...
