What is Centralized Air Conditioning?

Article By MG Cooling Solutions In HVAC - July 22, 2020

Centralized air conditioning provides temperature control and ventilation to an area. Centralized air conditioning is a system that utilizes supply and exhaust ducts installed in the floor or ceilings, mostly covered by grills. The cold air enters through the supply ducts when it gets warm to circulate out through the return or exhaust duct. Also, supply ducts made to control and regulate the volume of cold air getting into the room. Centralized Air Conditioner is of two types, Split-system unit and a packaged singular unit. The split-system unit centralized air conditioner contains condenser and compressor as an outdoor unit and evaporator as an indoor unit, besides the indoor unit has a furnace or a heat pump. In packaged singular unit, as the name suggests, all three components condenser, compressor, and the evaporator are housed in one single unit. The packaged singular unit often includes an electric heating coil for natural gas. The heating system is optional in most centralized air conditioning units. The combination of air conditioner and central heater eliminates the need for a separate furnace on a building during cold weather.

Apart from cooling or warming the air in a room or a building, centralized air conditioning regulates the humidity to a certain extent but not very helpful in areas with high-humidity, besides a dehumidifier in central air conditioning will result in high electricity bill. Having a central air conditioner installed in a building is costly than multiple portable units or room AC but, it is energy efficient, silent, and convenient to operate and maintain as multiple-portable units require more and frequent maintenance. Centralized air conditioning is cost-efficient in the long run and installed separately or underground, hence not spoils the beauty of the building. Few things must be kept in mind while installing a centralized air conditioning unit:

  • Ensure there is enough space for installation, future maintenance and repair.
  • Ensure that there is enough supply for exhaust ducts to deliver the Cool-air, and release Warm-air.
  • Make sure that the Ducts are proper-sized, measured, sealed, and insulated to prevent loss of energy and be more cost-efficient.
  • Install access panels for regular cleaning of air ducts.
  • Install the condensing unit for noise cancellation.
  • Ensure the airflow rate is as specified by the manufacturer.
  • The air conditioning unit must operate as per the manual provided by the manufacturer for its long and efficient operation.
