These were the first New York Central units to offer air conditioning, with sealed windows replacing the drop sash and clerestory types found on earlier cars. The initial set of 100 cars was retired in 1970, upon completion of the M1 railcar delivery, while the second and third orders, totaling 87 cars, remained in service until 2004, when they ...
Sustainable automotive air conditioning is the subject of a debate – also known as the Cool War – about the next-generation refrigerant in car air conditioning. An advocacy group, The Alliance for CO 2 Solutions , supports the uptake of carbon dioxide (CO 2 ) as a refrigerant in passenger cars, and the chemical industry is developing new ...
At the same time, air-conditioning was becoming a necessity, not a luxury, in commercial, industrial, and residential structures, making sheet metal workers an "indispensable factor" in the building and construction industry. SMWIA handled the job from beginning to end, fabricating and installing the ductwork, dampers, and louvers, a job required.
With air conditioning as a principal feature they became known as "AC Stock" and ran on type B4 bogies, with vacuum brakes. The order consisted of six First Class coaches (5101–5106), nine Composites (5151–5159), 36 Standard Class (5201–5236), eleven Restaurant/Buffet Standard Class (5401–5411) and eleven Generator Vans (5601–5611).

A liquid (glycol based) chiller with an air cooled condenser on the rooftop of a medium size commercial building. In air conditioning systems, chilled coolant, usually chilled water mixed with ethylene glycol, from a chiller in an air conditioning or cooling plant is typically distributed to heat exchangers, or coils, in air handlers or other types of terminal devices which cool the air in ...
HST coaches take an industrial voltage/frequency 3-phase supply directly from an auxiliary alternator in the power car to supply on-board equipment such as air conditioning; loco-hauled vehicles take a standard 1000 V DC or single-phase AC train heat supply from the locomotive and convert it through motor generator units under the floor. These ...
The interactions of the air and water flow allow a partial equalization of temperature, and evaporation of water. The air, now saturated with water vapor, is discharged from the top of the cooling tower. A "collection basin" or "cold water basin" is used to collect and contain the cooled water after its interaction with the air flow.
