Vehicle Tech in Lilydale are qualified to perform air conditioning repairs, services and regas on most makes and models.
A car air conditioning system contains four basic parts - a compressor (Pump driven by the engine,) which compresses and circulates refrigerant gas, a radiator like unit called a condenser to remove heat and condense gas to a liquid, the evaporator (a type of heat exchanger) to exhaust the heat from the car and dehumidify refrigerant and an expansion device called a thermal expansion valve (TXV) or an orifice tube, (dependent on the sort of air-con system used). An automotive air conditioning is designed to take the heat from the air within the passenger area of the car and carry it out of the car, leaving only cooled or 'conditioned' air behind to be redistributed. As hot air is passed across the fins of the evaporator the heat is easily absorbed by the refrigerant (in gas form), effectively removing the heat from the air in the car and taking it outside. The now heated gas is pulled through the compressor where it is further heated (via compression) to a very high temperature. The refrigerant is then literally forced through the condenser, allowing the cooler outside air to quickly extract the heat from the refrigerant as it is condensed to a liquid. The refrigerant then moves through the expansion device (either a TXV or Orifice tube), which regulates the flow of refrigerant going to the evaporator. At this point the refrigerant expands back into a gas form and the entire process begins all over again.
