Air conditioning is a process that is used to create and maintain optimum temperature levels in an indoor space. Often, people think that air conditioning works by creating cold air.
However, this isn’t entirely true.
In this guide, we’ll explain how air conditioning works as well as what the individual components in air conditioning systems do.
Air conditioning units work by removing the warm air from inside your home and pumping it outside, while releasing the cool air back into the room, reducing the temperature. When liquid becomes gas, it absorbs heat, and in principle, this is how they function.
Air conditioning systems work very much in the same way as your standard refrigerator, in that heat is absorbed inside the system and then removed from the room.
Here’s the process:
Inside a unit, there are a number of different components that manipulate the state, pressure, and temperature of the refrigerant, allowing the unit to do its job and cool the room.
We know that air conditioning units require a coolant liquid that is pumped through the coils to cool down the air. For the air conditioning process to work, this refrigerant circuit has to have three key components.
The warm air from inside your home is drawn in and passed through an expansion valve which regulates the flow. It is then blown over the cold evaporator coil, which absorbs the heat from the air. As the refrigerant inside the coils absorbs the heat, it changes back into a gas and moves towards the compressor.
The compressor in an air conditioning system acts as a pump, decreasing the volume of the gas and raising its pressure and temperature for the condensing process.
The air conditioning condenser takes the heat collected from inside the room by the refrigerant, now in vapour form, and pumps it outside where the outside air absorbs the heat and changes the state from a gas back to a liquid.
Once the heat has moved outdoors, the cold refrigerant travels back indoors to the evaporator to repeat the process.
A common misconception is that all air conditioners do is reduce the temperature of the air in a space. While this is its biggest job, they do much more than that. They also have a number of health benefits too.
There are also many other ways in which air conditioning can be beneficial:
