How does Freon work in an Air Conditioner

Air conditioning is a system specifically designed for controlling the temperature and ventilation of an enclosed area. It's a system that works through a cycle know as refrigeration cycle, in which cooler and more humid air is used to replace warmer air in other to enhance the improvement of the comfort of occupants. Air conditioning is used in vehicles, houses, offices and other enclosed area. It is used in both commercial and domestic environment to promote the comfort of humans or animals.

History of air conditioner

The principle of operation of air conditioners was based on refrigeration. Refrigerator was discovered in other to control spoilage of food as a result of bacteria. After the discovery of refrigerator, other application such as air conditioning and humidity control was discovered. The first electric air conditioner was invented in 1902. Freon was discovered in 1928 as a better refrigerant because it's safer to handle, compare to the harmful gases such as ammonia that were previously used. Air conditioning unit was later made more acceptable and efficient through the development of rotary compressor. The operation of air conditioners depends on the refrigerant.

The question is how does Freon work in an air conditioner?

Freon, a cooling agent or refrigerant is used in modern air conditioning system to lower the temperature of the room. The refrigerant or coolant generates cold air. The compressor in air conditioners will condense cool Freon gas, which is mixed with a small amount of lubricant to lubricate the compressor. The gas is then condensed at a raised temperature and pressure. The hot Freon runs through coils that lower its temperature and convert the Freon gas to fluid. The fluid run through a valve making it to become cold until it dissolves. The temperature then becomes very low. The cold Freon is guided to a set of coil which allows the gas to reduce the air temperature in the enclosed area or room. The sieve of the air conditioner removes dust, toxin, pollen allergen and smoke from the surrounding air. The whole system is cooled down through water intake from the air in the environment.

Types of air conditioners:

Different types of air conditioners have been designed and used. Examples are:

1) Central air conditioning : central air conditioners are the commonest and most preferable for larger homes due to its efficiency. It circulates cool air through supply and refine duct. The supply ducts and register in the wall or floor carry cool air inside and when the air becomes warm, it enters back into the supply duct and registers which then transport it back to the air conditioner. The installation requires sizing and must be done by a professional.

2) Ductless mini-split air conditioner; they also have outdoor condenser and indoor handling unit. It can cool rooms individually. One outdoor unit can serve more than one indoor unit in some designs. Other types are

3) Window air conditioners

4) Portable air conditioners

5) Hybrid air conditioners

6) Geothermal heating and cooling which works with the land.
