摘要

本文对涡旋压缩机进行了实验研究，重点研究了泄漏对其性能提高的影响。从实验和概念上研究了气体泄漏损失对压气机性能的影响。在本研究中，我们对涡旋压缩机进行了改进，使其通过泄漏孔旁路制冷剂，并实验研究了阀门开启面积和角度的影响，观察泄漏气体对压缩机性能、压缩机容量损失、排放管路温升和排放气体温度的影响。实验结果表明，在阀的最大有效开启面积为0.33 m2时，吸气过热度百分比的最大上升幅度为7.13%，而在整个有效泄漏面积范围内，排气管路温度的上升幅度为0.8% ~ 2.75%。此外，在实验的基础上，观察到8.9%的最大压缩机容量损失。

Experimental evaluation of the effect of leakage in scroll compressor

This research gives an experimental investigation of the scroll compressor, with an emphasis on the effect of leakage on performance enhancement. The effect of gas leakage losses on com-pressor performance is studied both experimentally and conceptually. In the present study, we have modified the scroll compressor to bypass the refrigerant through an orifice called leakage and experimentally investigate the effect of valve opening area and angle to observe the effect of leak gas on compressor performance, compressor capacity loss, discharge line temperature rise, and discharge gas temperature. Experimental results indicated that the maximum per-centage rise in suction superheat is observed to be 7.13% at a maximum effective valve open-ing area of 0.33 m2, whereas the rise in discharge line temperature lies in the range of 0.8% to 2.75% over the entire range of effective leak area. In addition, based on experimentation the 8.9 % maximum compressor capacity loss is observed.

期刊介绍： Journal of Thermal Enginering is aimed at giving a recognized platform to students, researchers, research scholars, teachers, authors and other professionals in the field of research in Thermal Engineering subjects, to publish their original and current research work to a wide, international audience. In order to achieve this goal, we will have applied for SCI-Expanded Index in 2021 after having an Impact Factor in 2020. The aim of the journal, published on behalf of Yildiz Technical University in Istanbul-Turkey, is to not only include actual, original and applied studies prepared on the sciences of heat transfer and thermodynamics, and contribute to the literature of engineering sciences on the national and international areas but also help the development of Mechanical Engineering. Engineers and academicians from disciplines of Power Plant Engineering, Energy Engineering, Building Services Engineering, HVAC Engineering, Solar Engineering, Wind Engineering, Nanoengineering, surface engineering, thin film technologies, and Computer Aided Engineering will be expected to benefit from this journal’s outputs.
