Advanced Design Bus Ventilation Testing

摘要

This final report is the result of a test program conducted to compare the following Advanced Design Bus (ADB) ventilation systems identified by the Ventilation and Air Conditioning Subcommittee (VACS) of the American Public Transit Association (APTA): power ventilation using components of the air conditioning system; openable windows within the fixed passenger windows; and roof hatches. The two coaches that participated in the testing were the RTS-11 model (manufactured by General Motors Corporation) and the 870 model (manufactured by Grumman-Flexible Corporation). Both coaches featured large unopenable windows and were tested against the discontinued New Look design coach with openable windows.
