How Does AC Work in a Car? A car's air conditioning works by manipulating pressure and temperature to move refrigerant between a liquid and gaseous state. The refrigerant enters the evaporator as a liquid, and the heat of the car transforms it into a gas. In its gaseous state, refrigerant...
How AC Works When the thermostat signals the air-conditioning system to lower air temperature, a whole sequence of events begins. First, the air-handling unit kicks on, drawing room air in from various parts of the house through return-air ducts. This air is pulled through one or morefilter...
You’redriving down the road. It’s a beautiful, hot day in the middle of July. Suddenly, the cool stream of air blowing into your face cuts out. Or, even worse, the air turns warm. Having a functioning air conditioning system in your car is a key part of a pleasant drive, ...
Just like in normal air conditioning, the coolant cycles between gas and liquid, high and low pressure, and high and low temperature.How car aircon works Ever wondered how your car's aircon keeps you cool? It goes a bit like this... Artwork: How car aircon works (simplified). The ...

The organophosphate contamination of cabin air is caused when aero-engine oil and/or hydraulic fluid leaks into the cabin air conditioning system, the air supply for which is drawn from the jet engine compressors. This contamination is not supposed to happen, but from time to time “fume events...
Air-conditioned seats that use refrigerated air either contain a small cooling element based on this principle, or use air pumped from the main cooling element of the car's air conditioning system. Because the space being cooled is limited to a single seat, relatively little energy is required...
Most portable air conditioning units have wheels attached at the bottom. They are also lightweight and can be easily moved from one room to another, depending on your needs. Portable air conditioners are generally less energy efficient. The reason is they take more time to condition a room tha...
