In your vehicle, the automotive air conditioning compressor has the simple task of moving gas between the condenser and the evaporator. However, it is often considered to be the heart of the system and if this belt-driven piece of equipment fails to do its job, the entire system quits functioning as designed.
The automotive air conditioning compressor is typically attached to the engine of your vehicle and is belt driven. One of the primary causes of a failed automotive air conditioning compressor is a loose or broken belt as a loose belt may not operate the compressor properly causing lowered pressure in the system and the gas is not transferred to the system’s other components efficiently. Similar to the air conditioner in your home or office, the vehicle’s system has three main components, the automotive air conditioning compressor, a condenser and an evaporator.
The vehicles closed system contains Freon gas and the automotive air conditioning compressor pressurizes the gas, which converts it to hot, high-pressure gas and forces it into the condenser, which looks similar to the radiator in your car, to dissipate the heat condensing the hot, pressurized gas into a liquid. As it is forced through an expansion valve it evaporates into cold, low-pressure Freon gas.
