CTA的每辆新車均有一套10吨的空調系統,能在外溫95℉及車內乘客多至125人时,使車內溫度降至75℉,相对湿度亦能保持在50～55%之間。要作到这一点,需要在一定的情况下将空气过冷及重加热。普尔曼斯坦塔公司(P-S),在完成CTA的定貨中,在采用空气調节装置的同时,在新車上还有下列几点: 采用焊接式鋁质車身及高强度鋼的底架; 应用靜止变流器及靜止逆变流器,为交通車內的控制及照明,供应能量;
Each CTA has a 10-ton air-conditioning system for each new car, reducing the car’s temperature to 75 ° F and the relative humidity between 50 and 55% at an external temperature of 95 ° F and as many as 125 passengers in the car . To do this, it is necessary to overcool and reheat the air under certain conditions. Pullman Tower Company (PS), in completing the CTA’s order, uses the air-conditioning unit as well as the following points on the new car: a welded aluminum chassis and a chassis of high-strength steel; stationary Inverter and static inverter, for traffic control and lighting, energy supply;
