What is HVAC control?

The HVAC control term concerns the automated air conditioning control system in buildings. HVAC is an abbreviation for heating, ventilation and air conditioning and includes complete internal handling of the climate of any building or space. HVAC control systems usually consist of computer networks in large buildings and separately, systems with one driver in home or smaller places. Both are constantly monitoring and adjusting the internal climate of the building according to preset parameters measured against the input of sensors located throughout the space. These air -conditioning control systems often include peripheral functions such as fire, lighting and security and may also contain diagnostic and remote controls.

Any space operated by one or more central climatic systems usually needs a centralized mechanism that monitors and modifies the internal climate if necessary. HVAC control systems meet this requirement by monitoring sensor input in relevacintaround the space and their comparison with known parameters. These parameters are defined and stored in the controllers and serves as a scale for system operation. If the flow or temperature of the air in a particular area or zone of the building deviates from these parameters, the HVAC control system automatically hits to correct the situation.

This intervention may come in the form of electronic signals sent to fan control panels, air conditioning and heating or pneumatic or hydraulic controllers operating holes or valves. Electronic messages can communicate to the appropriate device to turn on or off, raise or lower the temperature and divert, reduce or turn off air, water, or flow of steam. In very large devices, there may be several HVAC parent control points, each of which controls several smaller systems. In homes or small buildings, the HVAC function is limited to theDNA control station.

HVAC control terminals are generally controlled by Digit Digital Control (DDC), which can be programmed using user -specific data. Depending on the sophistication of the system, users may define a wide range of climate criteria for their environment. These include identification of zones or specific areas in space, temperature and air flow control and setting specific times for heating or cooling cycles in these specific areas. Increasing sophistication in HVAC control technology and demand for One-Stop solution also noted the inclusion of lighting control, security system monitoring and fire protection in these applications. Another recent development is a remote access function that allows users to initiate HVAC controls via Ethernet.
