An HVAC (Heating, Ventilation, and Air Conditioning) control system is an integrated set of hardware and software components designed to monitor, manage, and regulate the operation of an HVAC system. These control systems ensure the indoor environment is comfortable and energy-efficient and maintain good air quality by automating and optimizing the performance of heating, cooling, and ventilation equipment performance. An HVAC control system typically consists of the following components: Sensors: These devices measure various parameters such as temperature, humidity , and air quality in different building zones. The collected data is sent to the control system for processing and decision-making. Controllers: These are the central processing units of the system. Controllers receive data from sensors and run algorithms to determine the appropriate actions to maintain the desired indoor environment. Controllers may be standalone devices or integrated into building management systems (B...
