If you know about How does an Air conditioner work? Air conditioners, which are used to provide a cool and dry environment. Although the Air Conditioner Working Principle and its process provide cool air, its primary purpose, as the term describes, is for conditioning air (or atmosphere) that is comfortable for humans.

How Does An Air Conditioner work?
Here, I discuss How an air conditioner works? The technology behind the air conditioning system and the fridge is exactly the same – the refrigeration cycle.
This processing is mainly done using these five components:
- Expansion valve
Systems that take advantage of this cycle use special chemicals that are used to absorb refrigerant (water in some systems) and/or to cool the heat or to release any air.
When these chemicals are compressed by the compressor of the AC unit, the refrigerant changes from gas to liquid and releases heat into the condenser.
When cooling a place, this process takes place outside the space in question. This high pressure, now cold air is pumped into the indoor unit and expanded back into the gas using the system’s expansion valve.

Air Conditioner Working Principle With Video Tutorial
The Working Principle Of An AC system called a refrigerant cycle. This cycle has four major components of all air conditioning systems. These components and their basic functions are listed below.
A compressor is a device that increases the gas pressure and also increases the temperature by increasing the molecular motion of its particles.
The compressor gets cold refrigerant gas by evaporation and releases very hot and pressurized gas into the condenser. The purpose of the compressor is to ensure that the heat received from the inside is well activated before it spreads to the atmosphere from the surroundings.
Last Line: The refrigerant is drawn from the evaporator and pumped into the condenser by the compressor. The compressor also pressurizes the refrigerant vapor so that it easily changes the state (condensing).

The purpose of the condenser is to obtain high-pressure gas from the compressor and convert this gas into a liquid.
This is achieved by heat transfer or thermodynamic theory that heat usually moves from a warmer place to a colder place or from a warmer material to a cooler material.
However, the air passing through the condenser coil carries the heat away, condensing the gas. It is essential to quickly note that the condenser typically looks like the one found in the engine radiator.
The condensers used on the R-134a and R-12 systems are not interchangeable because the earlier molecular structure is different and requires a larger capacity condenser. The condenser is the second part of the Air Conditioner Working Principle.
Last Line: The high-pressure refrigerant vapor releases heat through the condenser coil as it condenses into a liquid refrigerant. Makes it easier to evaporate.
3. Expansion Valve
The expansion valve system consists of very narrow tubes that extend along the length. These tubes, known as capillary tubes, collect the condensed (liquid) refrigerant from the condenser and carry it through an expansion process (where the fluid pressure drops drastically).
As a result, there is also a decrease in the temperature of the fluid. This drop in temperature leads the fluid to a position in which it initially enters evaporation. The process of expansion can also be referred to as a throttling process in a thermodynamic cycle.
This is because its main purpose is to reduce the pressure of the fluid. Apart from these four basic parts of air-conditioners, there are many other parts which are important in making the system effective and efficient. Thermostats, high side, and low side ports as well as metal hoses all ensure that there is proper flow of fluid as well as temperature regulation.
Last Line: The flow of liquid refrigerant from the condenser to the evaporator. As the refrigerant passes through the metering device, its pressure decreases.

4. Evaporator – Last Process Of Air Conditioner Working Principle
The evaporator is the fourth in AC Working Principle Under its name, evaporation occurs, where the refrigerant fluid evaporates. The evaporator is located in the internal unit. It constitutes mostly tubular pipes that are wound to multiple layers. These tubes serve as a passage for very cold refrigerant liquid.
Its essence is to absorb the heat (the latent heat of evaporation) from inside which vaporizes this liquid into a very cool gas. The evaporator does not necessarily increase the temperature of the refrigerant but it definitely changes its phase (liquid to gas).
By doing this the evaporator performs two functions. First, it cools the atmosphere of the interior by removing heat.
And secondly, since the temperature of the refrigerant is well below the freezing point of water, this means that the water vapor in the atmosphere loses thermal energy and transforms its phase into liquid and then solid ice which is a white coating. Evaporator tube as it appears.
This function reduces relative humidity and therefore produces a drier environment inside. The evaporator receives its cold refrigerant liquid from a suction port that is connected to the expansion valve and delivers cold gas to the compressor in the external unit.
Behind the evaporator is a fan or blower that increases the kinetic energy of the air around the evaporator, this ensures convection heat transfer so as to speed up the purpose of air-conditioning.
Last Line: The low-pressure liquid absorbs the refrigerant as it evaporates into the evaporative coil. The process described above is the refrigerant system or refrigerant cycle. It is the system on which virtually all modern air-conditioning and refrigeration is based.
