摘要

目前还很少有关于CO2跨临界喷射式制冷循环的研究。本文对CO2跨临界喷射制冷循环建立了热力学模型

计算了在不同的冷却压力、冷却器出口温度、加热器压力、加热器出口温度及蒸发温度下

喷射器的喷射系数、跨临界喷射制冷循环性能系数(COP)和有效性能系数(COPm)的变化趋势。结果表明:随着冷却器压力的升高

喷射器的喷射系数减小

循环的COP 和COPm值先增大后减小

在某个冷却压力下存在最优值;提高冷却器的出口温度

循环的COP 和COPm值均降低;提高加热器压力、加热器出口温度及蒸发温度均能增大喷射器的喷射系数和循环的COPm值。

Abstract

The research on transcritical ejector refrigeration cycle with CO2 is rarely reported.In this study

a thermodynamic model for a transcritical ejector refrigeration cycle is established.The changes of ejector entrainment ratio

the cycle performance coefficient (COP)and effective performance coefficient (COPm)with cooler pressure

cooler outlet temperature

heater pressure

heater outlet temperature and evaporation temperature are presented.As the cooler pressure increases

the entrainment ratio of ejector decrease

the cycle COP and COPm first increase and then decrease

with optimum values at some cooler pressures.As the outlet temperature of cooler increases

both values of COP and COPm decrease.With the increase of heater pressure

heater outlet temperature and evaporation temperature

the ejector entrainment ratio

the cycle COP and COPm are improved

while the cycle COP decreases with the increase of heater outlet temperature.
