An HVAC control system regulates heating, air conditioning, and ventilation in buildings. It can be manual or automatic and is customized to each building’s needs. Advanced systems use sensors to adjust components automatically. HVAC control systems are often part of a larger building automation system, offering easy control and improved energy efficiency.
An HVAC control system is a computerized mechanism used to regulate heating, air conditioning and ventilation components within a building. It can have manual or automatic operation and is often customized to the specific needs of each building. The HVAC control system can be used to turn a furnace or air conditioner on or off, or to adjust the temperature and other settings on these units. Depending on the application, these controls can also be used to regulate other types of building systems. In addition to allowing owners to easily control systems within a building, an HVAC control system is also used to maximize performance and energy efficiency.
The standard HVAC control system relies on controllers, or actuators, integrated into various components within the system. Using a central computer system, operators can direct each actuator to turn on the furnace or air conditioner or adjust the temperature of each. This system also allows users to open or close dampers within HVAC ducts or adjust ventilation fans using the same computer software. Some simply display HVAC system information on a computer screen, while others have built-in alerts that notify operators when settings need to be changed.
More advanced HVAC control systems also include sensors that help automatically adjust these components with minimal operator input. The sensors on the heating or cooling unit work just like a home thermostat and adjust the operation of the unit to meet pre-programmed temperature settings. Others make automatic adjustments based on air quality needs or the presence of smoke, fire or excess moisture.
An HVAC control system is often incorporated into a larger building automation system (BAS). These systems not only regulate heating and cooling, but also control lighting, security systems, communication, and fire control. They use software that allows operators to control the system on site or from remote locations. This web-based control allows maintenance personnel to easily deal with emergencies or changes at any time and from anywhere in the world.
Buildings equipped with an HVAC control system offer many advantages over those without these systems. Easy-to-use controls enable building personnel to maximize performance, comfort and productivity for workers and occupants. They also help improve energy efficiency and reduce heating and cooling costs. An improvement in energy efficiency also helps reduce the consumption of fossil fuels, which offers many benefits for the environment.
