Central System

Definition

A central system is a system for conditioning air supplied to various areas or spaces, serviced by the same source of heat or cooling. All equipment in central systems, except air-cooled condensers, evaporative condensers, and cooling towers, are indoors.

Purpose

The purpose of a central system is to efficiently manage the heating, ventilation, and air conditioning (HVAC) needs of large buildings or multiple zones from a single, centralized location. This ensures consistent climate control and energy efficiency across the serviced areas.

Examples of Use

1. Office Buildings: Using a central HVAC system to regulate temperature and air quality in different office zones.
2. Hospitals: Employing a central system to maintain sterile and comfortable conditions throughout various departments.
3. Hotels: Providing guests with individually controlled climate settings via a central system that manages the overall heating and cooling.

Related Terms

• HVAC: Heating, Ventilation, and Air Conditioning systems used for indoor climate control.
• Air Handling Unit (AHU): A device used in central systems to condition and circulate air.
• Chiller: A machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle, used in central systems for cooling.

Notes

• Central systems are often more energy-efficient than multiple standalone units.
• Regular maintenance is crucial to ensure the system operates effectively and efficiently.
