As summer approaches, temperatures begin to rise and for many the only best way to beat the heat is to use air conditioning. The number of homes that have air conditioning in our country increases every year and are getting closer to 50%.
An air conditioning system keeps your home or business cool in the hot summer months, but have you ever wondered how air conditioning works?
AIR CONDITIONING PARTS
The air conditioning system uses a series of chemicals that go from a gaseous to a liquid state within a circuit. These chemicals transfer heat from the air inside a room to the outside air.
An air conditioning unit has three fundamental parts: the compressor, the condenser and the evaporator. The compressor and condenser are usually located on the outside of the air conditioning system. And inside the house is where the evaporator is located (in what we know as split).
When the air conditioner is on carrying out the cooling process the refrigerant fluid reaches the compressor as a low pressure gas. The compressor squeezes this gas out and the molecules in the liquid condense. The closer the compressor is to these condensed molecules, the greater the increase in temperature and energy.

HOW THE AIR CONDITIONING WORKS STEP BY STEP
- When you start the air conditioning, the first thing that happens is that the hot air in the room is drawn in through the grill. This is generally located at the base of the machine or interior split.
- The air passes through the cooling pipes through which a cooling liquid circulates. The incoming air is cooled and a dehumidifier is responsible for removing excess moisture.
- Afterwards, the air continues its way through the circuit until it reaches a fan that expels said air back into the room through another grill.
- Meanwhile, the refrigerant (a volatile liquid that evaporates easily) circulates through the tubes of the cooler. As it does so, it collects heat from the air that blows through the pipes and evaporates, turning from a cold liquid to a warmer gas. It transports this heat from inside the room to the outside of the building, where it expels its heat to the outside air. This is achieved thanks to the refrigerant liquid flowing through the compressor and condensation pipes. There it turns back into a cold liquid ready to cycle around the loop again.
- The heat from the air that was inside the house is expelled to the outside through the external unit placed outside the building. This part of the air conditioning machine has a fan that dissipates heat into the atmosphere. Thus, little by little, the heat from inside the building is expelled to the outside.
AIR CONDITIONING OPERATION
As we can see, the operation of industrial air conditioner is based on a circuit in which physical and chemical changes take place. The refrigerant fluid exits the compressor as a high pressure hot gas and moves towards the condenser. The outdoor unit of an air conditioning system has metal blades around the housing. These blades work like the radiator in a vehicle and help dissipate heat more quickly.
When the liquid comes out of the condenser, it is much colder. It has also changed from a gaseous to a liquid state due to high pressure. The liquid makes its way into the evaporator through a tiny, narrow hole. When it reaches the other side of this circuit, its pressure drops. At that moment the fluid begins to evaporate and turn back into gas.
Thanks to this process the heat is extracted from the surrounding air. This heat helps to separate the molecules from the liquid and make it a gaseous state. The metal evaporator blades also help exchange heat energy with the surrounding air.
When the refrigerant substance leaves the evaporator, it is again a low pressure refrigerated gas. The process starts over when you return to the compressor. There is a fan that is connected to the evaporator. Its function is to circulate the air inside the room and through the evaporator blades.
The process continues until the indoor air in your home or business reaches the desired temperature. When the thermostat detects that the indoor temperature is at the desired level, the air conditioner turns off. And when the room heats up again, the thermostat turns on the air conditioning again until the set room temperature is reached again.
Now you know how the air conditioning works . What we are sure you already knew is that air conditioning systems have become the great allies of Man to combat high temperatures. Especially in the warmest areas of the world or in the summer season when the heat is suffocating.
