153系电车使用在二十多年以上,以后已由185系特快电车所代替。现将185系电车的采暖和换气性能的测试结果介绍如下。 1.车内换气量车内换气量的测试是采用二氧化碳衰减法(测试二氧化碳浓度)。测试时在车内设3个测点,然后求其平均值。车内换气量(车顶处装有2组强迫通风装置)在静止时为1628米~3/时,而运行时为1395米~3/时,比静止时少14％,但比设计值1320米~3/时多5.6％,所以符合设计要求。 2.车体隔热性能为避免太阳辐射热的影响,试验在日落后进行。主要测试了车内各部温度、采暖热
153 Department of tram used in more than 20 years later has been replaced by 185 Department Express tram. 185 series tram heating and ventilation performance test results are as follows. 1. Car ventilation The car ventilation test is the use of carbon dioxide decay (test carbon dioxide concentration). Test in the car with 3 measuring points, and then find the average. The amount of ventilation in the car (with 2 sets of forced ventilation devices installed on the roof) was 1628 m 3 / hour at rest and 1395 m 3 / hour at operation, 14% less than at rest, 1320 m ~ 3 / 5.6% more, so meet the design requirements. 2. Car Body Insulation To avoid the effects of solar radiation heat, the test was performed after sunset. The main test of the various parts of the car temperature, heating and heating
