单元式空调机组变工况性能试验研究

Experimental Research on Packaged Air conditioning Unit at Different Conditions

铁路客车单元式空调机组变工况特性是研究空调机组、指导检修和运用的重要依据 .对单元式空调机组基准试验样机进行了变工况性能试验研究 ,得到了一种特性拟合方程 .借助该方程 ,能获得基准样机非名义工况制冷量和电流数据 。

The performance of train packaged air conditioning unit(PAHU) at different conditions provides the basis for study,overheal and operation.This paper carries on test research on performance of defined basis test sample PAHU(BTS PAHU) at different conditions,and results in a set of fitted equations.The refrigerating capacity and current of BTS PAHU at different conditions,which is the reference for study,overheal and operation,may be obtained by solving the equations.
