How Does Car Air Conditioning Work?
A sealed, high pressure system with a drier and an expansion valve, modern car & van air conditioning systems utilise a compressor to compress a refrigerant gas. A pump moves the gas through the air conditioning pipes. Over time the gas gradually escapes the system resulting in no cold air from the car's interior vents. This is why your car's air conditioning system needs re-gassing (recharging) and occasionally repairing & cleaning. Mostly just vulnerable to compressor bearing wear and leaks these days with minor maintenance modern air con systems are designed to generally out live the vehicle.
