Buildings and large infrastructures generally have central air conditioning. A central air conditioning unit uses a split system for its condenser and compressor. The evaporator is attached to an air handling mechanism or a forced air furnace. The whole system is housed in a packaged unit that is often located outdoors, such as a rooftop or an outhouse.
Cooled air is distributed to the different floors and rooms through air ducts. A tenant may raise or lower the temperature through controls located in each room. Some buildings do not have such temperature controls. Tenants will have to deal with the common temperature set for all floors.
There are advantages to using a centralized air conditioning system. With the unit located outdoors, tenants are not bothered with the ambient noise that comes with a running air conditioning unit.
A sophisticated filtering system also cleans the air circulated in the whole building. Through various return-air ducts, room air is continually pulled and filtered. Through this process, dust particles and even microscopic pollutants are weeded out from the circulating air.
A centralized air conditioning unit also allows building administrators and engineers to control the energy consumption and voltage requirements of tenants. With a centralized air conditioning unit, tenants need not plug in their own stand-alone air conditioning unit.
In cooling or controlling temperatures, it is important that you can determine and dictate the total temperature. This is because it is easier and more economical to cool rooms with consistent temperatures. With a centralized air conditioning unit, you can do such.
When choosing the right brand or model for a central air conditioning unit, consider its filtering ability. Circulating air must be kept clean and fresh. Otherwise, you will be spreading pollutants to all areas of your building.
To give your tenants utmost convenience, you may have to provide them with the means to control the temperature on their respective floors. You may have to work with an architect to equip each floor with built-in controls.
