How to choose a suitable Air Conditioner?

Based on the factors discussed above, the following constraints should be kept in mind before purchasing an air conditioner: (i) What is your maximum budget? (ii) How much cooling power do you really need? (iii) Energy Consumption - Typically the air conditioning system installed within the house forms the largest part of the total electricity bill. (iv) Space Requirements - How much and what type of free space is available for installing the air conditioning system. (v) Maintenance - Is it easy to service the air conditioning system? Cost of repair, availability of spare parts, etc. should be considered before making a purchase.

Refrigerant, Compressor, Evaporator & Condenser Coil

Refrigerant is a fluid that undergoes a repeated phase transition from liquid state to gaseous state and back again. It is the refrigeration cycle of an air conditioning system that uses a refrigerant flowing within coils that makes heat transfer possible.

The Condenser Coil is located within the outdoor unit of the Split Air Conditioner. The condenser coil works with the compressor to convert the refrigerant that is in gaseous form back to a liquid. The heat produced in this heat exchange cycle is dispelled in the open external environment.

The Evaporator Coil is located within the indoor unit of the Split Air Conditioner. The evaporator coil has refrigerant flowing within it and is responsible for absorbing the heat from within the room and transporting it outside. The evaporator coil works with the condenser coil as a result of which cool air flows out of the air conditioner into the room.

The Compressor is the work horse of an air conditioning system. The compressor located in the outdoor unit helps bring in the outside air. This air cools down when the liquid refrigerant absorbs the heat and changes into gas. Inside the indoor unit, the refrigerant vapor absorbs the heat from the room and travels back to the compressor. This heat exchange cycle enabled via the compressor continues until the temperature drops and reaches the level set in the thermostat. Ductwork and fans within the air conditioning system move the excess heat out of the room when the compressor is running.
