摘要
目前地铁空调厂采用室内焓差法进行冷量测试,依据国外规范,对空调机组制冷量需采用辅测法进行校核,使主辅测法制冷量测试偏差在6%范围内,即表明制冷量测试满足要求。介绍一种辅测法,改进行室外焓差法测量机组制冷量,在不增加额外试验设备的前提下,满足冷量校核的要求。
Currently, The cooling capacity test method for railway HVAC unit is indoor enthalpy differencial. In order to check the cooling capacity whether meet the requierment or not, according to forerign standandard, a secondary test method is neccessary.The delta for the test difference should be within 6%, that cooling capacity will be confirmed. The paper introduce a secondary method, it can check the cooling capacity without increasing additioanl test instruments.
