摘要

空调、冰箱等家用小型制冷设备提供舒适居家环境的同时，其产生的噪声也成为消费者投诉的关键问题之一。本文运用掺气空化理论对电子膨胀阀进行结构优化，通过加装旁通管将蒸发器入口处的制冷剂引入至电子膨胀阀出口处进行掺气，提高制冷剂局部流动压力，有效地抑制两相流中气泡的破裂，改进后的双旁通电子膨胀阀和四旁通电子膨胀阀对出口处制冷剂气泡破裂产生的噪声具有极大的降低作用。经数值模拟和实验验证研究发现，双旁通电子膨胀阀和四旁通电子膨胀阀比原电子膨胀阀产生的噪声值分别降低2.729 dB(A)和3.778 dB(A)。

Abstract

While small household refrigeration equipment such as air conditioners and refrigerators provide a comfortable home environment

the associated noise has become one of the key reasons behind consumer complaints. This study uses the theory of air-entrained cavitation to optimize the structure of the electronic expansion valve. The refrigerant at the inlet of the evaporator is introduced to the outlet of the electronic expansion valve through the installation of a bypass pipe to increase the local pressure of the refrigerant

such that the bursting of bubbles in the two-phase flow can be effectively suppressed. The improved double-bypass electronic expansion valve and four-bypass electronic expansion valve may significantly reduce the noise generated by the refrigerant bubble burst at the outlet of expansion valves. Numerical simulation and experimental verification studies show that the double-bypass electronic expansion valve and four-bypass electronic expansion valve reduced noise by 2.729 dB(A) and 3.778 dB(A) than those of the original electronic expansion valve.
