Retrofit Air Conditioning of Subway Cars.

摘要

Recognizing the desirability of air conditioning as an inducement to attract patrons and offer them amenities that make rail mass transit comfortable as well as convenient,new car orders specify inclusion of air conditioning equipment (where climatic conditions justify consideration). Married pari cars and shared undercar equipment paired cars,as well as improved packaging,permit relatively easy installation in new vehicle purchases. The challenge is to air condition existing subway cars whose remaining life precludes replacement. Resolution of complicated design and retrofit problems faced by the New York City Transit Authority in its effort to develop a method of air conditioned cars on its IRT Division are described in this paper.
