Decoding the Mechanics: How Does Air Conditioning Work?

Summers in Australia are absolutely hard to endure without a proper air conditioning system. Ever had a curiosity that how to do these amazing systems work? In this article, you are going to read about some important components and mechanisms of air conditioning systems. 

These mechanical systems are used for cooling and reducing the humidity in indoor spaces. They provide comfort by managing the temperature. Air conditioning systems are usually installed in buildings, homes, offices, and vehicles. 

Components of Air Conditioning Systems

An air conditioning system releases heat from an indoor space to the outside and lowers the temperature. The following components are involved in the mechanism of an air conditioning system. 

• Compressor

The main component of air conditioners is the compressor. It is used for the compression of refrigerant gas. 

• Condenser

The outdoor component of an air conditioner is called a condenser. It is responsible for cooling the hot compressed gas and then converting this gas into a high-pressure liquid. 

• Evaporator

The heat exchanger installed inside the house is called the evaporator. This expands the high-pressure liquid, which is received from the condenser. This process causes the liquid to evaporate and absorb the indoor air heat. 

• Refrigerant

It is a fluid that circulates all around the system. It releases and absorbs heat as soon as it is converted into a liquid from a gas. 

• Expansion Valve

The expansion valve is responsible for the regulation of refrigerant flow. The fluid flows into the evaporator which expands and cools it. 

• Fan or Blower

Fans or blowers circulate the air in the evaporators and condenser coils for the transmission of heat. 

• Ductwork

Ductwork is used for the distribution of the cooled air throughout the whole space i.e. a building. This is usually in central air conditioning systems. 

• Thermostats

In modern air conditioning systems, there also are thermostats that maintain the speed of fans and regulate the temperature of the room. 

Types of Air Conditioners

Air conditioning systems come up in many different types. These include central air conditioners, split systems, window units, ductless systems and more. It is up to your perspective to install the system according to your budget and the size of your household. 

For the installation, you can contact the electricians perth of HQ Electrical & Air. They are well-trained and perform their jobs by ensuring your safety. 

Mechanism of Air Conditioners

The air conditioning systems installed in our houses go from the following steps to provide us with cool and comfortable air. 

Air Intake

It gathers the indoor warm air and releases it out through the air vents. 

Air Filtration

Firstly, the air passes from a filter net to remove all its extra dust and various allergy particles. This is done to improve the quality of the air. 

Cooling Procedure

• The air is compressed through a compressor to manage its temperature and pressure. 
• Then heat passes into the condenser which is converted into a liquid from a gaseous state. 
• The pressure is further reduced in the expansion valve. It causes the expansion of refrigerant, thus dropping its temperature. 
• The refrigerant consists of low temperature and pressure enters the evaporator. The indoor air goes inside the evaporator coils and the refrigerant absorbs heat from this air. 
• This causes the refrigerant to evaporate and becomes a low-pressure gas. 

Circulation

Then the air is forced by a blower over the evaporator and heat is transferred to the refrigerant. The air is now cooled and distributed in the room. 

Reduces the Humidity

Evaporator coils let the moisture in the air condense on cold coils. This reduces humidity in the room. This moisture is dripped in the drain pan and thus removed from the system.

Refrigerant Cycle

Warmed gas returns back to the compressor and the procedure is now repeated in the cycle. The desired indoor temperature finally remains maintained. 

Role of Thermostat

Most of the temperature in the air conditioning system is controlled by the thermostat. It gives a sign to the system to trip, or to on or off it. This is done to keep the temperature maintained according to the user’s requirements.

Conclusion

If you want your air conditioning system to be well-maintained and in better condition, the electricians of HQ Electrical & Air are providing air conditioning services for its repair and installation. You can contact them for further information.
