Abstrakt
The results of measurements of operating parameters of a refrigeration unit, carried out before and after replacing the refrigerant R404A with R448A, are presented and compared.
Analyses include, among others, comparing the power and energy consumption of the reciprocating compressor in a two-evaporator compression refrigeration system operating at the selected settings of chamber temperature and superheating. The cycles of the compressor are also presented.
