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 ...
High-efficiency all-electric refrigerant compressors for air conditioning are starting to be used, especially in hybrid or all-electric vehicles. The cigarette lighter receptacle serves as a de facto standard for use of portable 12 volt equipment in or near an automobile, it is sometimes used with car charger to power devices with batteries.
The Nash "All-Weather Eye" was the first automobile air conditioning system for the mass market. [2] The use of the Weather Eye name for automobile passenger heating and air conditioning systems continued in American Motors Corporation (AMC) vehicles. The design principles of the Nash Weather Eye system are now in use by nearly every motor ...
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 ...
In order to fit the air-conditioning equipment into the motor cars, the pantographs were moved to the trailers, effectively meaning that a motor car must remain semi-permanently coupled to a trailer car. Four driving trailer cars D4096–4099 were also ordered, allowing 2-car sets to be operated with power cars C3501–3504.
Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...
A condenser unit used in central air conditioning systems typically has a heat exchanger section to cool down and condense incoming refrigerant vapor into liquid, a compressor to raise the pressure of the refrigerant and move it along, and a fan for blowing outside air through the heat exchanger section to cool the refrigerant inside. A typical ...
HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...
