Essentially, the ac unit works on the successive heating and cooling of a super-volatile fluid called Freon. The latter first goes into the compressor and is compressed into gas form, therefore giving off heat and cooling the fluid as a result. The dispelled heat is then fanned out with the help of a rotating fan. Next, the liquid gets into the condenser and soaks up the surrounding heat to transform into vapor once again. So obviously, the surroundings cool off. This whole process goes on in a cyclical pattern, therefore lowering the temperature level in the room.
Apart from the three above major parts of an air conditioning unit, the device also has a hot coil, a cool coil, one exterior fan, one interior fan, and a control circuit in it. The hot coil is placed outside to dispel the heat out, and the cool coil is placed inside to absorb heat. The control circuit modifies the temperature level by controlling the rotation speed of the fans with the help of a potentiometer.
Of all its components, the compressor remains the most valuable and expensive part of an air conditioning unit. So, the ac unit manufacturers always offer a service warranty on the compressor. A compressor of superior make and quality has a long life and functions fine over years. And, if the original compressor gives you problems, it can be replaced with a new one. Its simple to purchase a new compressor and fit in your old ac unit. However, here it is always a good idea to choose the compressor of the same brand as that of the rest of the machine. However, the problem is that only a handful of companies make their own compressors. All the others just purchase them and install it in their air conditioning units.
The evaporator and condenser in an air conditioning unit can be replaced too Visit this webpage . So can the coils, in case they break. Any troublesome coil can result in defective heat-dissipation, and lead to a major malfunctioning after that. The two fans are the most basic of ac unit parts that can be easily replaced, precisely because they are fixed with screws on the outside, and with wires inside the ac unit circuit board.
