Experimental Study of the effects of Throttle valve on Auto-cascade Refrigeration System

摘要

The objection of this article is to optimize auto-cascade refrigeration system. This refrigeration system use multiple mixture (R22/R23/R14) as the refrigerant, which is driven by the single-stage compressor. Throttle is an important composition of auto-cascade refrigerant system, which impact on evaporation temperature and refrigeration efficiency. This article concrete on experimental study on throttle opening and length of capillary. The comparing data reflect the influence of the throttle valve on refrigeration efficiency. So as to improve working efficiency of all non - azeotropic auto-cascade refrigeration system. It offers data and reference for the auto cascade refrigeration system theory in the future.
