摘要

在相变过程中实施气液分离可实现强化传热。本文将气液分离应用于变频空调系统中

通过匹配实验获得了系统最佳充注量和毛细管长度

在标准工况下系统制冷能效(Energy Efficiency Ratio

EER)为2.57

制热模式下系统能效(Coefficient of Performance

COP)为3.68

并研究了不同制冷、制热工况下的系统性能。为反映系统实际运行性能

进一步比较了不同城市实际运行全年能源消耗效率(Annual Performance Factor

APF)。结果表明: APF值在腾冲市最高

为3.67

在沈阳市最低

为2.81。系统在不同城市运行

性能差异显著

国标不能真实反映系统的实际运行性能。

Abstract

The implementation of liquid-vapor separation in the phase change process can achieve heat transfer enhancement. Liquid-vapor separation was applied to inverter air conditioning system. The optimal refrigerant charge amount and capillary length of the system were obtained through matching experiments. At the standard operating condition

the obtained EER and COP are 2.57 and 3.68

respectively. The system performance is also examined under different cooling and heating conditions. The annual performance factor (APF) of actual operation in different cities was compared to reflect the actual operating performance of the system. The results showed that the highest APF value was in Tengchong

at 3.67

and the lowest in Shenyang

at 2.81. It shows that the performance of the system varies significantly in different cities. Moreover

the performance at the standard operating condition largely differentiates that at the actual conditions.
