Things to Know About Air Conditioner

Air Conditioner keeps the room temperature cold, thereby making you feel fresh and active. It has the capacity to control high temperature. It also removes dust, germs and micro organisms from the air.

Types of Air Conditioners
There are various types of air conditioners available, choosing one depends on the size of the area that needs to be cooled.
  • Window AC: It is a single unit and is mostly used in small and single rooms. It is easy to install and maintain. Compressor, condenser, cooling coil, expansion coil are enclosed in one unit.
  • Split AC: Split AC has two units, external and internal. The internal unit is installed inside the room and the external unit is installed outside the house. The internal unit takes in the warm air and throws out cold air. The external unit throws away the warm air.
  • Central AC: Central AC is appropriate for large areas, it has the capacity to cool big houses, hotels, offices, movie theaters, etc. It is very silent and comfortable.
  • Tower AC: Tower AC is free floor standing unit, consisting of two units - internal and external. Internal unit is free standing and no installation is required, whereas external unit has a compressor that connects to the internal unit. This AC is ideal for commercial purpose.
Working of Air Conditioners
The AC removes warm air from the room or house and throws cold air. The warm air is cooled by cold pipes known as evaporator coil. A liquid known as refrigerant is filled in these pipes. Refrigerant converts liquid in to gas when taking in the warm air and thereby absorbing heat from the air. The refrigerant is moved into another coil that is located outside the house where it converts into liquid by releasing heat. The compressor helps in moving the refrigerant between the coils by changing pressure and making the refrigerant evaporate into gas. The motor uses the energy to run the compressor.

Maintenance of the Air Conditioners 
Air conditioners should be maintained on regular basis for effective functioning. Following are the parts that should be maintained :
  • AC filters: Some filters should be replaced, whereas some can be reused. Clean the AC filters once in two months and if the AC's are used regularly, filters should be maintained more frequently.
  • AC coils: A clean filter keeps the coil free from becoming dirty. But still it collects dirt, due to which the airflow is reduced and the ability to absorb heat decreases. Check the coils frequently and clean whenever required.
  • Coil fins: Coil fins are located on the evaporator and the condenser coil. By replacing these fins by a tool called fin comb the fins will be back into original condition.
  • Condensate drains: If the drain channels are blocked, humidity reducing capacity of the unit decreases, which results in excess moisture. So clean the drains by passing wire that are stiff to check whether the drain channels are blocked or not.
