What Is The Process Of Air Conditioning System?

Although air conditioners come in a range of sizes and designs, they all work on the same fundamental principle. Air conditions have become essential in the current rising temperature. Have you ever wondered how your air conditioning system keeps your house or place of business cool during the sweltering summer months?

You might be surprised to learn that your refrigerator and air conditioner function mostly in the same way. The main distinction is that whereas an air conditioner maintains a suitable temperature in your house, workplace, or business area, a refrigerator only cools a small, insulated room.

Many individuals are under the impression that their air conditioner produces frigid air. Not at all. Instead, they function by transporting the heat from within your house to the outside. So, just how does this procedure operate? Discover it in this article.

What Is The Process Of Air Conditioning?

When examining the workings of air conditioning systems, mass and energy conservation are applied. For living spaces like homes, businesses, and industrial facilities to be kept at the right temperature and humidity, an analysis of air conditioning operations is necessary.

These are the fundamental procedures:

  • Basic Methods Of Heating And Cooling;
  • Air Conditioning And Dehumidification
  • Humidification When Heating;
  • Adiabatically Combining Two Air Streams;
  • Condensation Cooling

What Normally Occurs When The Air Conditioner Is Turned On?

The thermostat built into the air conditioner will notice a difference between the temperature of the room air and the temperature you have selected when you switch it on and set the desired temperature, say 20 degrees Celsius. This heated air is drawn in through a grill at the base of the interior unit, and it then passes through several pipes that carry a coolant called a refrigerant.

The refrigerant fluid takes in the heat and turns into a hot gas as a result. As a result, the air that touches the evaporator coils loses heat. In addition to absorbing heat, the evaporator coil also removes moisture from the entering air, which aids in dehumidifying. The compressor, which is housed on the outer unit, receives this heated refrigerant gas after that.

As implied by its name, the compressor heats the gas by compressing it, which raises its temperature. The condenser, the third component, is eventually reached by this hot, high-pressure gas.

In this instance as well, the condenser fulfills its name by condensing the heated gas into a liquid. The refrigerant enters the condenser as hot gas, but it soon condenses to a cooler liquid as a result of metal fins dissipating heat into the surrounding air.

Once a result, as the refrigerant exits the condenser, it loses heat and cools down. This passes via an expansion valve, a tiny hole in the copper tube of the system, which regulates the flow of the cold liquid refrigerant into the evaporator, bringing it back to where it started its journey. Even though all of the parts of a window air conditioner’s air conditioning system are contained in the same metal box, the fundamental cooling process is the same.

Up until the necessary temperature is attained, the entire procedure is repeated. In essence, an air conditioner continually draws in warm air, cools it, and then pushes it out into the space until no more warm air is there for it to cool.

Detail Processing Of An Air Conditioner:

Now that you know the basics of air conditioner operation, let’s delve a bit further and go through the full procedure. The thermostat monitors and regulates the temperature of the interior air and is normally installed on a wall in the middle of the house.

The thermostat sends signals to the air conditioning system components inside and outside the home to begin operating when it determines that the air temperature needs to be decreased. Through return air ducts, the fan from the indoor unit draws hot air from the inside of the building.

Dust, lint, and other airborne particles are gathered in filters when this air flows past them. The heated, filtered interior air is then forced over the chilly evaporator coil. The heat from the interior air is absorbed by the refrigerant as it transforms from liquid to gas, cooling the air as it passes over the evaporator coil.

The cooled air is then circulated back through the ductwork of the house and into the different living spaces by the blower fan of the indoor unit. Through a copper tube that exits the house, the refrigerant gas is transferred to the compressor of the outside air conditioning unit.

The compressor can be compared to a big electric pump. The compressor pressurizes the refrigerant gas before delivering it to the condenser coil of the outside unit. The condenser coil allows exterior air to collect thermal energy from the house and release it outdoors. A sizable fan drives the air through the coil.

The refrigerant undergoes this transformation back to a liquid. After that, it returns to the interior unit through a copper tube and goes through an expansion device to control the flow of refrigerant into the evaporator coil. The cycle then repeats as the cold refrigerant continues to absorb heat from the interior air.


The basic idea behind all air conditioning systems is the same: hot air is ejected, often into the outside atmosphere, while heat is removed from one area and replaced with cold, dry air.

The air goes through the evaporator, which holds the sub-cooled refrigerant, to release the chilled, dry air into the room. The condenser, which contains the high-temperature gas, is where the air again flows through the veins, gathering the heat as it does so before being discharged outdoors.
