A new water-cooled auto-cascade refrigeration cycle(WACR) using a binary refrigerant mixture is presented
which adopts a condenser-phase separator instead of a condenser and an evaporative separator in traditional auto-cascade refrigeration cycle. In condenser-phase separator
high boiling point refrigerant can be condensed
and high boiling point and low boiling point refrigerants can be separated. Characteristics of four binary refrigerant mixtures (R22/R23
R290/R170
R134a/R23
and R134a/R170) circulation were analyzed. And the WACR using R22/R23 and R134a/R23 were studied experimentally. In the same condition
the COP of WACR using R22/R23 is higher than that of the WACR system using R134a/R23. Compared with the traditional system
COP of the new water-cooled auto-cascade refrigeration cycle(WACR) is higher from 60% to 100%.
