Air conditioner

An air conditioner works to change the temperature of the surrounding air and cooling it to release a cool breeze from the AC. The AC system consists of five major parts and other parts of the AC all working together to keep you and others cool. Most AC systems have the following components:

  • Compressor
  • Condenser
  • Accumulator
  • Orifice tube also known as the Expansion valve
  • Evaporator
  • The AC system also consists of pipes and refrigerant charging ports, but the significant work occurs in the five parts listed above. The refrigerant is the liquid used to transport heat from one part to the other. The AC simply works to change the pressure and thereby resulting in causing changes in temperature. When you turn the AC on and the compressor compresses the system’s refrigerant raising its temperature as it absorbs heat. It then loses heat when it flows through the condenser where it is cooled using the condenser fans. It then passes through the receiver or dryer where contaminants and moisture are removed using the desiccant and the filters, and then on to the expansion valve where the refrigerant is slowed down further, causing it to lose pressure and temperature before it gets to the evaporator. The evaporator cools down further to lower the refrigerants temperature. The ventilation system blows air over the cold evaporator and pushes this cool air into the passenger compartment.

    Refrigerant is the fluid medium used to transport heat from one part of the air conditioner to the other components. The refrigerant has the ability to change state from liquid to gas when it absorbs heat due to its low boiling point. When the hot gas is cooled in the condenser it reverts back to liquid when it loses its heat of vaporization. Older models of cars use the refrigerant R-12 which is harmful to the ozone layer. There is a protocol that is now used to regulate that all new AC models must have R-13a.Though the R-134a has no effect on the ozone layer it is less efficient. Your certified technician can change your AC system to suit it to the R-134a.He will then evacuate it and then fill it with R-134a according to the manufacturer’s specifications.

    Air conditioners need to be serviced regularly for them to function properly for years and in order to be able to detect any problems that will come up. Some of the problems go undetected are the leakages of the AC. Leaks are hard to detect because when refrigerant leaks it evaporates so you will not find any signs of leakage apart from noticing that your system is not working properly or efficiently. So regular servicing of your system will save you costs of repair and replacement from underlying problems that may be silently destroying the major components.

    If you notice that your air conditioner is not working properly or its performance is not optimum you can arrange for a repair company to come check and fix your AC.
