CAR AIR CONDITION BLOWING BUT NOT COOLING

CAR AIR CONDITION BLOWING BUT NOT COOLING

A major cause of air conditioning problem discovered while working as a trainee and also as a student of mechanical engineering from the prestigious Federal University of Technology , Akure in Nigeria were the points which are enumerated below with few possible solutions. These are

1.         Low refrigerant is the most common cause of  air conditioner not cooling well in cars and at large as where applicable

 2.        The most common cause of compressor failure is inadequate lubrication. This may be the result of a refrigerant leak that allows compressor oil to leak out of the system. Leaks can be detected with the use of leak detectors like halide torch detector, electronic leak detectors and locally the soap bubble leak detector.

3.         Lubrication problems can also be caused by a blockage (typically the orifice tube) that prevents refrigerant and oil from circulating through the A/C line system.

Moreso, using the wrong type of compressor oil for lubrication or the wrong amount can also lead to premature wear and failure. There are various grades of PAG oil, try use the right type as specified in manufacturers manuals and in the right quantity.

4.            Damaged blower motor fan or faulty blower motor can cause the system not to blow cold air and as such frost is formed along the cooling line. Replace fan or motor pending on which is the fault associated with the device.
