Air conditioner compressor
Air conditioners are a system of components that work together to change the temperature of the air around to make it as comfortable as possible. A typical air conditioner is made up of five major components which are refrigerant, compressor, condenser, expansion valve, and the evaporator coil. This is a summary of the roles of each of the major components:
The refrigerant is the liquid medium pumping through the air conditioners system. It changes state from gas vapor to liquid as it collects heat from your house and rejects that heat to the outside. Refrigerant has a very low boiling point meaning that when it absorbs heat it changes from a liquid to a vapor at low temperatures. The compressor is the central part of the air conditioner and is responsible for the system pumping the refrigerant though all the air conditioners components. When refrigerant enters the compressor as a low pressure warm vapor and leaves it as a high pressure hot vapor. The compressor is the core and key primary part of every AC system. The compressor is the component that pressurizes the refrigerant and it absorbs heat and leaves as a hot gas. It senses temperature changes using a compressor clutch. It is powered by a serpentine belt in vehicles. It is a very expensive part to replace and therefore you should arrange for regular maintenance of your unit. When refrigerant comes into contact with moisture it becomes corrosive and starts to eat away at the components and pipes. This causes leaks that are not easily detected though you will notice a change in the performance of your unit. When a technician wants to check for leakage he will use a special dye and backlight because refrigerant evaporates when exposed to air. Then he will fix the holes formed by sealing them. If the compressor is not too badly damaged he can fix it. However, if he cannot fix it he will recommend that you replace it. Replacements are easy to do because most companies have stocked the various parts of the air conditioners.
Regular maintenance will prevent emergency breakdown of your system.
