Author(s) : ZHAO Z., YANG Y.

Summary

In order to probe into the secondary throttling the cool completely in the middle of the two-stage compression system running characteristic of under low temperature conditions, the evaporation temperature t0 = -20 ? , temperature of condensation temperature tk =30 ? ~50 ? condition, analysis the secondary throttling intermediate cycle characteristics of the cooling system completely, analysis showed that the evaporation pressure is constant, as the condensing temperature rising, condensing pressure and intermediate pressure increasing, the tendency of increase with the condensing pressure is higher than the pressure in the
middle of the trend, system COP and decreases with the increase of condensation temperature, high and low level flow ratio increases with the increase of condensation temperature and slow; Condensing pressure is constant, with the constant rise of evaporation, the evaporation pressure and intermediate pressure increasing, the system COP also increases with the increase of evaporation temperature, high and low level flow ratio increases with the evaporation temperature decreases slowly;
