摘要

毛细管是制冷空调装置中常用的节流元件之一.毛细管的流动特性对装置的系统性能影响显著

因此

建立一个好的毛细管模型对于装置的设计和优化都是必要的.尤其是近年来

CFCs环保问题的影响

推动了毛细管研究从理论和实验两方面向着工质替代的方向发展.从文献中的毛细管模型来看

早期的模型受计算工具等条件的限制

大都比较简单

精度也不高;近年来

这些限制不再存在

研究者趋向于采用分布参数模型以提高预测精度.但是

分布参数模型在计算速度和计算的健壮性方面尚有欠缺

不适用于实用型的系统仿真和优化.因此

建立简单、准确、通用的毛细管模型

具有重要的理论和应用价值.

Abstract

An accurate and simplified model of flow characteristics in capillary tubes is necessary for intensive study on the system performance of refrigeration plants equipped with capillary tubes. Especially

the modelling of two-phase flow in capillary tubes is important and difficult. In this paper

a novel general integral model of two-phase flow in capillary tubes is developed. The comparison with the distributed-parameter model of capillary tube using the refrigerants R12

R134a and R600a as working fluids turns out to be satisfactory. The results show that the recommended integral model is within 3.4% maximum deviation and 1% mean deviation. In computation speed

it is at least one order of magnitude faster than the distributed - parameter model.
