Air conditioning is one of the most outstanding equipment for the home as it will provide you with the necessary comfort to withstand the hot summer days. In this guide we tell you everything you need to know to choose the best air system suitable for your needs.
When summer and good weather arrive, in addition to increasing the demand for sun loungers and umbrellas for the beach , the purchase of air conditioners also increases.
These types of devices are essential to maintain comfort inside the home when outside the heat falls like a slab on those who dare to challenge it. It is in these cases when an air-conditioned home is the best refuge during the hottest hours .
In this air conditioning buying guide we show you everything you need to know before deciding on a specific type of air conditioning: advantages, disadvantages and technologies to take into account before buying the air conditioner you need.
How does an air conditioning system work?
Before choosing an air conditioning system, it is advisable to know how this system works in order to understand what function each component performs in the cooling process.
Do not worry. We are not going to tell you the whole theory of thermodynamics , but a basic explanation of the refrigeration circuit. Actually, the operation of an air conditioner is not very different from that of your refrigerator, but it is equipped with more power.
Did you know that the air conditioning does not introduce cold air into the rooms , but what it does is extract the hot air? If you stand near an air conditioning outlet, you will notice that the air in that area is considerably cooler than the rest, and a certain draft is noticeable.
This can confuse many users into believing that air machines cool the air, when what they really do is use a heat transfer process to extract ambient heat and use a fan to distribute the “converted” air throughout the rest of the room. stay. But the amount of air in the room is constant.
The air conditioning system consists of two main elements: the indoor unit and the outdoor unit . A tight system of copper tubes through which a refrigerant gas circulates joins both elements and changes from a liquid to a gaseous state at different points in the circuit.
In the indoor unit there is the evaporator in which the heat is extracted from the room air and a ventilation system that is responsible for distributing the fresh air throughout the room.
For its part, the outdoor unit houses the compressor that maintains the internal pressure of the system to keep it moving by applying pressure when appropriate, the condenser and an expansion valve .
This gas leaves the outdoor unit in a semi-gaseous state through the copper tubes and reaches the evaporator of the indoor unit. There it traps the heat of the air that changes its state to gaseous. This refrigerant gas returns to the external unit where it passes through the compressor to increase its pressure and through a condenser where it becomes a liquid and in which it is cooled by expelling the hot air into the street.
Then, it passes through the expansion valve where the reverse process to that of the compressor takes place, releasing part of the pressure on the refrigerant gas and returning it to the original semi-gaseous state to restart the cycle.
This is, in a basic way, the cooling process and the components present in any air conditioning system and what function it performs. Now we only have to know what technologies are applied to each element, or what distribution of components is appropriate for your needs. In short, what to take into account when choosing an air conditioner .
We have told you in a basic way the operation of an air conditioning system , but manufacturers have managed to develop systems that scale depending on the cooling needs of your home.
Choosing the type of air conditioning installation is one of the first – and most important – decisions you must make when planning the purchase of an air conditioning system for your home .
