Making the a/c turn on?

One of the first things to understand about air conditioning system is to realize what is meant by the term ‘air cooled’.

This means that the air conditioning system plan uses a chemical refrigerant to remove heat from the air! Years ago, this refrigerant was referred to as ‘freon’, however it has been phased out in newer models.

Water-cooled air conditioning systems are usually used in large buildings, using water instead of refrigerants to cool the air, refrigerants are added when the plan is first installed & cycles continuously through the components of the air conditioning system unit. The a/c absorbs the heat & moisture from the indoor air & releases it to the outside. The evaporator/air handler equipment is located inside the building & the compressor & condenser are located outside. Heat is removed from the interior air at the evaporator coil. This long metal coil has plenty of surface part for the air to transfer over the coils in order to be cooled. When the air leaves the evaporator coil, it enters the compressor – or the heart of the system, and it’s the compressor’s job to pump the refrigerant through the plan – much love a human heart pumps oxygen through the blood system. The condenser coil releases the absorbed heat to the outside! Next, the outside fan blows air over the condenser coils to help release heat. The indoor fans transfer air over the evaporator coils & blow cooled air into the ducts, which ultimately makes its way to the individual rooms of the house. The real trick of cooling the air has to do with removing moisture, or humidity, from the air. The refrigerant is used to remove moisture, which flows down through condensation lines & then drained away. And THAT’S how air conditioning system works.
