节能型汽车空调压缩机综合试验台的研制 摘 要: 汽车空调压缩机是汽车空调系统的核心,检测其质量性能的设备大多性能单一,且结构和原理基本相似,大多采用第二制冷剂量热器法。基于压缩机排气管道量热器法和制冷剂气体冷却法,结合某企业技术协议的要求研制了性能和耐久性综合试验台。介绍了试验台的总体设计方案和系统组成,并对其工作原理和关键部件的选型设计进行了阐述。该试验台最大特点是将部分零件模块化。与传统的测试设备相比,该试验台便于连续进行测试。该试验台的测试误差均在标准规定的精度范围内,满足了企业的测试要求。研究为其他相似试验台的设计提供了借鉴。 关键词: 汽车空调; 压缩机试验台; 节能; 模块化 中图分类号: TB 657; U 467 文献标志码: A Development of an Energysaving Compressor Test Bench for Automotive Airconditioner YANG Eryang, LI Zhengtao, YANG Shuling, RONG Yaopeng, HAN Cong (School of Energy and Power Engineering, University of Shanghai for Science and Technology, Shanghai 200093, China) Abstract: Compressor is the core part of automotive airconditioner system.And its performance testing equipment was mostly simple with similar construction and principles by means of the second refrigerant calorimeter method.A new set of performance and durability test bench was developed in this study based on the compressor exhaust pipe calorimeter method and refrigerant gas cooling method,in accordance with an enterprise technical agreement.The overall design scheme and system composition were introduced.Its working principles and selection design of key components were described in detail.The biggest characteristic of this test bench was the modularization of some components.Compared with traditional testing equipment,the new one was convenient for doing some continuous tests.The deviation from this test bench met well with the testing standards,which could satisfy the company’s testing demands as well.It could provide some references for the design of other similar test benches. Keywords: automobile airconditioner; compressor test bench; energy conservation; modularization ?S着汽车大量进入寻常百姓家,人们对室内生活环境的各种需求就延续到汽车中,汽车空调便成为满足人们对车厢环境要求的装置。压缩机是空调器的心脏,其寿命直接影响汽车空调的有效使用时间[1],其性能影响能量的使用效率。压缩机综合性能试验台可用来评价汽车空调压缩机的好坏。对于长时间的耐久性试验,节能型试验设备就显得尤为重要。 目前国外很多公司和科研机构都有专门的压缩机耐久性试验台和性能试验台,但对于综合性能的试验台很少有研究[2]。国内试验台大都沿用传统的测量方法(如第二制冷剂量热器法)将性能和耐久性试验分开测试。王磊等[3]、方大伟等[4]、王晓燕[5]都利
