Know Your AC unit Parts.

Basically, the air conditioning 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, thus emitting 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 enters the condenser and absorbs the surrounding heat to transform into vapor once again. So obviously, the surroundings cool off. This whole procedure goes on in a cyclical pattern, thus lowering the temperature level in the room.

Apart from the 3 above major parts of an ac unit, the machine also has a hot coil, a cool coil, one outside fan, one interior fan, and a control circuit in it. The hot coil is put outside to dispel the heat out, and the cool coil is put inside to soak up 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 important and pricey part of an ac unit. So, the air conditioning unit manufacturers constantly provide a 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 substituted with a new one. It's simple to buy a brand-new compressor and fit in your old air conditioning unit. However, here it is always advisable to go for the compressor of the same brand name as that of the rest of the machine. However, the issue is that only a handful of companies make their own compressors. All the others just buy them and install it in their air conditioning units.

The evaporator and condenser in an ac unit can be replaced too. So can the coils, in case they wear out. Any bothersome coil can lead to defective heat-dissipation, and lead to a major malfunctioning after that. The two fans are the most basic of air conditioning unit parts that can be easily replaced, precisely because they are fixed with screws on the outside, and with wires inside the air conditioning unit circuit board.Http://www.bjrefrigeration.com/\nProfile
