Fan Coil Unit System Zoning

Definition of System Zoning for Fan Coil Units

System zoning for fan coil units involves dividing a building into multiple zones and controlling the temperature and airflow in each zone separately. This can be achieved by installing individual thermostats in each zone and configuring the fan coil units to respond to the specific temperature settings of each zone.

How System Zoning Works

System zoning works by utilizing dampers within the fan coil units to control the airflow to each zone. When a thermostat detects a need for cooling or heating in a particular zone, it sends a signal to the corresponding fan coil unit, which then adjusts its damper position to provide the desired airflow and temperature. This allows for independent control of each zone’s climate.

Key Components of System Zoning

The key components of system zoning for fan coil units include individual thermostats for each zone, dampers within the fan coil units, and a central control system. The thermostats sense the temperature in their respective zones and send signals to the central control system. The control system then communicates with the fan coil units to adjust the dampers accordingly, ensuring that each zone receives the desired heating or cooling.

Types of Zoning Systems

Single Zone Systems

In single zone systems, the entire building or space is treated as a single zone, with a single thermostat and control system. While this approach is relatively simple and cost-effective, it may not provide the desired level of comfort for occupants. Single zone systems are commonly used in smaller residential buildings or spaces where precise temperature control is not critical.

Multiple Zone Systems

Multiple zone systems divide a building into two or more zones, each with its own thermostat and control system. This allows for more precise temperature control and comfort customization in different areas of the building. Multiple zone systems are commonly used in larger residential buildings, office spaces, and commercial facilities where individualized comfort is important.

Variable Air Volume (VAV) Systems

Variable Air Volume (VAV) systems take zoning to the next level by providing individual control over both temperature and airflow in each zone. By adjusting the volume of air supplied to each zone based on its specific needs, VAV systems offer enhanced comfort and energy efficiency. This type of zoning system is typically used in larger commercial buildings where different zones have varying occupancy and thermal loads.

System Control Methods

Thermostat Control

Thermostat control is the most common and straightforward method of controlling fan coil units.
