Study of Water-cooled Auto-cascade Refrigeration Cycle with a Low Temperature of﹣60 ℃
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 re...

| Summary: | 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%. |
