What Are The Functions Of Air Conditioning (A/C)?

Air conditioning (A/C) is a method of climate control for buildings, automobiles, and other enclosed spaces. Air conditioning commonly uses a refrigeration cycle but sometimes utilizes evaporation or free cooling.

The most important function of air conditioning is to make a room or building cooler. A/C does this by taking in hot air and converting it to cold air.

Regardless, if it is a room AC or a car AC, the functions will be the same. You can also search for Car Aircon Regas to revitalize your car’s air conditioning.

Today we will see what are the most important functions of an air conditioner.


There are several functions of air conditioning, however, the main purpose is to cool. Air conditioners lower the temperature of all air entering or leaving through the system to the desired set temperature. As a cost-effective way of cooling and heating, air conditioning systems can be installed for residential or commercial use.

Heat is removed from inside the room by an evaporator coil which is cooled by the refrigerant circulating through it. The refrigerant expansion makes the temperature lower than the surroundings and this heat is transferred away from the room. The cool air is then circulated throughout the space by using fans.


Dehumidifying is the process of removing moisture from the air. This moisture can come from your breathing or other sources like the outside of your residence or building. This moisture may cause discomfort and damage to other objects within the building like wallpapers or wood furnishings. Dehumidification within air condition systems helps to prevent overexposure to mould, mildew and also reduces potential damage in other areas.

Humidity in the air is directly related to its temperature, so apart from removing heat, a well-designed A/C unit will also dehumidify the air. Excessive humidity can cause mould growth as well as other problems such as allergic reactions and respiratory infections.

Air conditioning (A/C) is known to be one of the most basic multi-functional home appliances. Aside from being a cooling system, air conditioners also dehumidify or remove humidity within the room. This is done by transporting moisture into the A/C’s evaporator coil where it gets cooled and condensed into water.

Air purification

Air conditioning systems clean the air by removing dust particles and other contaminants. Active carbon filters and electrostatic filters are the most common methods used in a/c systems to remove contaminants from the air.

Air purification changes or removes the odors, airborne bacteria, and viruses in the air. This ensures that clean air being circulated in your home is as free as possible from harmful particles, allergens, and irritants.

Bottom Line

This post has described some of the basic functions of an air conditioner. Air filtration, humidification, and dehumidification, temperature control, all are pretty basic functions of your air conditioner (AC). If you want to breathe healthy air, regardless of season, you should install an inverter AC in your room for temperature regulation, dehumidification, and air purification.
