铁路客车空调机组检修中制冷压缩机排量的检验

Inspection of Refrigerator Compressor Displacement in Maintenance of Railway Passenger Car Air-conditioning Unit

简述了铁路客车空调压缩机排量试验台的设计参数和工作原理。设计的试验台为双循环系统,主要包括空气循环系统和制冷循环系统两部分。同时介绍了试验台的设计和试验情况,通过进行验证性试验,确定试验台的测试精度在10%以内。

This article briefly describes the design parameters and working principle of therefrigerator compressor displacement test bench for railway passenger cars. The designed test bed is a two-cycle system, which mainly includes the air system and the refrigeration system. The design and test conditions of the test bench were introduced. Through verification tests, the accuracy of the test bench was determined to be within 10%.
