Room Air Conditioners

Air Conditioners are designed to provide human comfort by lowering the room temperature and humidity. Despite Air conditioners consuming large amount of electricity, their popularity amongst the general public is increasing.

Two types of air conditioners are present in the market:

Window Type

In this type of air conditioner, all the elements of the system are enclosed in a single casing.

Split Type

In this type, there are two units of the system. The outdoor unit comprises of the compressor, condenser and condenser fan. The indoor unit comprises of the evaporator as well as the air handler.

It is mandatory to have BEE star label on Room Air Conditioners since January 2010. The Energy Efficiency Ratio (EER) calculates the efficiency of an air conditioner. EER is measured as a ratio of cooling output per hour to the power input for an air conditioner. Thus, higher the EER, more is the energy efficiency of an air conditioner.

  • The windows and doors of the room in which air conditioner is being used should be kept shut.
  • Any blockage to the path of air to air conditioning unit should be removed for efficient operation.
  • The temperature of the AC should be set at the point of human comfort during summers. For each degree above 22, the electricity consumption reduces by 3 to 5 percent.
  • Keep heat generating appliances out of the air path of the AC as the thermostat on sensing heat from other appliances leads to longer running of the AC.
  • The filter of the AC needs to be cleaned on a regular basis. Dirty air filter leads to reduction in the air flow.
  • Dust needs to be removed from the outdoor coils on a regular basis. In dusty conditions, the efficiency of the AC reduces.
