How Do ACs Work? All You Need to Know

Everything you need to know about an air conditioner

Are you thinking about purchasing an air conditioner? Looking at IFB AC prices so you can pick a great model for you? Before you do any of that, you must remember to ask, ‘what is the definition of an air conditioner? The definition, the refrigeration cycle, and the Basic Principle of Air Conditioning are all explained in depth here.

When you’re outside in the heat of the day, the delights of summer can soon change to tiredness and exhaustion. What would we do if air conditioning didn’t exist? In these hot months, we all need it. And, given how much we enjoy the advantages of a good air conditioner, it’s only natural to wonder: what exactly is an air conditioner? What is the mechanism of an air conditioner? What components are required to keep us cool? Which is the best option for me? How can I save money on my energy bills?

The air conditioner, also known as an air conditioner in some countries, is a piece of modern technology that we might consider a marvel. The unit’s primary function is to dehumidify and reduce the temperature of the air in a regulated environment. Most air conditioners use the refrigeration cycle to cool the air within.

To lower the temperature of the space, some air conditioning devices use evaporation or cooling. When it comes to household equipment, these devices often use 110 VAC or 220 VAC electrical power.

Air conditioners require some effort to run; otherwise, entropy would naturally decrease, which would violate the Second Law of Thermodynamics. Air conditioners work similarly to heat pumps, but it is called cooling since it uses heat extraction. A refrigerant material is handled in numerous phases to cool, which we’ll go over in greater detail below.

What is the Process of Air Conditioning?

This apparatus can alter the temperature, humidity, or overall air quality. An air conditioner cools your home by collecting heat energy from inside and transporting it outside, then replenishing the air inside with cooler air.

In volatile liquid form, the refrigerant goes via a type of radiator known as the evaporator in a simple air conditioner, such as a window unit, through which the air into the room passes. When the coolant comes into touch with the radiator, it evaporates and absorbs the heat in the air.

A fan circulates the cooled and dehumidified air back into the room. The moisture content of the cooled air condenses on the radiator fins when it approaches saturation – water cascades down the fins and into the sewers.

The vaporised refrigerant flows via a compressor, where it is compressed and driven into a second radiator and then the condenser. Under these conditions, the refrigerant condenses back into liquid form, releasing the heat absorbed within the room into the air blown between the condenser’s fins.

Due to the pressure change, the hot air is ejected outside, and the refrigerant liquid passes through the expansion device, its temperature lowering to refrigeration levels.

The refrigerant completes the cycle by passing through the evaporator once again to continue the cooling process. The two sets of radiators on some units can reverse functions so that the internal radiator condenses the coolant and heats rather than cools the room in the winter. A heat pump is a type of equipment like this.

What exactly is a BTU?

Calculating the amount of electricity necessary for the environment where you want to place the air conditioner is critical for selecting the appropriate equipment for your needs. Many people, however, are unsure how to conduct this computation. The air conditioning BTU, a measurement used to quantify the power of an appliance against the size of the space in which it is placed, is the primary source of these doubts.

A tonne of refrigeration equals 12,000 BTUs in terms of heating and cooling. A typical window air conditioner has a 10,000 BTU capacity. For example, assuming you need roughly 600 BTU per m2, a 100 m2 house can have a 5 tonne (60,000 BTU) cooling air conditioning system.
Please keep in mind that these are approximations. Contact a specialist specialising in HVAC (Heating, Ventilation, and Air Conditioning) equipment to build an air conditioner for your specific needs.

What is the purpose of the air conditioner?


Air conditioning machines have a primary function. It contributes to cooling and accurate temperature management of the room through the cooling system.


In devices with an inverter function, you can cool or heat the space. These appliances provide a comprehensive solution for residential air conditioning, with the added benefit of using the air conditioning for heating via a heat pump.

It is a more environmentally friendly alternative to typical heating because it draws energy from the outside air.

Purification of the Air

Filters in air conditioning units help deliver clean, healthy air by removing dust, pollen, and pollutants. Filtration levels can be increased according to the needs. Filtration is critical for allergy sufferers, but filters must be maintained regularly to keep them in good condition.


The air conditioner’s cooling mode also dehumidifies the air. A proper humidity level inhibits the growth of mites and mould, which is beneficial to allergy sufferers. A 40 to 60 per cent humidity level is the most pleasant for people.


This feature extracts air from the interior and replaces it with fresh, conditioned air from the outside. When the air conditioner is turned off in the middle of the year, such as in fall and spring, the ventilation can function independently.
