How does a centralized air conditioning system work?

Centralized air conditioning is a convenient and cost-effective method of providing relief from hot, humid weather. It has the following benefits. 

  • It makes environments comfortable and when installed in industrial and commercial setups, it boosts staff efficiency and productivity. 
  • It keeps the air clean by absorbing airborne particles through the air filters. 

As the name ‘centralized air conditioning’ suggests, the entire building is conditioned from a single location. The air is cooled and dehumidified at one location and then it is distributed throughout the whole place with the help of fans and ducts. The main function of a centralized air conditioning system is to throw warm inside air from inside out of the building.

The main components of a centralized air conditioning system are as follows.

  • Fans: They circulate air through the system.
  • Evaporator coils: They change the refrigerant from liquid form to gaseous.
  • Compressor: It compresses the refrigerant gas. This gas enters here at low pressure and low temperature. After compression, it comes out at high pressure and high temperature. 
  • Condenser coils: They turn refrigerant gas into a liquid.  Here, the gas gives up its heat to the medium flowing through the condenser.
  • Refrigerant lines (ductwork): They carry the refrigerant gas between the coils. 
  • Expansion device: It regulates the amount of refrigerant gas flowing to the evaporator.  

And now let’s understand how the centralized air conditioning works. Its basic principle is that when a liquid changes into a vapor, it absorbs some heat and creates a cooling effect.  In the same manner, a chemical in gaseous form, known as the refrigerant, circulates through the AC system. It absorbs heat while changing into a liquid, and the warm air is then dumped outside. This happens in a continuous cycle and produces a cooled, clean environment. 

We hope you find this information useful. Whenever you wish to install an air conditioning system at your setup, do contact Ventech Systems. They would love to assist you.
