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 ...
Many residential central heat pump and air conditioning systems and a few automotive air conditioning systems employ a scroll compressor instead of the more traditional rotary, reciprocating, and wobble-plate compressors. A scroll compressor operating in reverse is a scroll expander, and can generate mechanical work.
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 ...
A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air ...
An automobile auxiliary power outlet (also known as car cigarette lighter or auxiliary power outlet [1]) in an automobile was initially designed to power an electrically heated cigarette lighter, [1] but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile directly from the ...
In a car equipped with air conditioning, outside air, or cabin air if the recirculation flap has been set to close the external air passages, is first forced, often after being filtered by a cabin air filter, through the air conditioner's evaporator coil. This can be thought of as a heater core filled with very cold liquid that is undergoing a ...
The Schrader valve is used on virtually all automobile tires and motorcycle tires and most wider-rimmed bicycle tires.In addition to tube and tubeless tires, Schrader valves of varying diameters are used on many refrigeration and air conditioning systems to allow servicing, including recharging with refrigerant; by plumbers conducting leak-down pressure tests on pipe installations; as a ...
An air conditioner designed for an occupied space will typically achieve a 30% to 60% relative humidity in the occupied space. [51] Most modern air-conditioning systems feature a dehumidification cycle during which the compressor runs. At the same time, the fan is slowed to reduce the evaporator temperature and condense more water.
