VSD fan control improves variable air volume system Variable Air Volume or VAV systems have some kind of system to control the air volume. The most common has been damper control, but variable speed control of fan motors is the most economic method to control the air volume. The system is usually designed […]
Mitsubishi F800 offers more than just energy savings. Although the motivation behind installing variable speed inverter drives is invariably payback based on energy savings, modern drives like Mitsubishi Electric’s FR-F800 offer more than just energy savings for building users. Building users and facility managers continually look for ways to save energy […]
Energy efficiency in the public sector In decentralising services, government is moving more responsibility and decision making to Local Authorities. Budgets however do not necessarily follow, and more money must be raised locally. Given that governments are driving energy efficiency measures forward, one can imagine that the public sector must be […]
ABB improves air quality in HVAC drive applications For residential, commercial and industrial buildings, a heating, ventilation and air conditioning (HVAC) system maintains the desired air quality by controlling temperature, pressure, humidity, air change and carbon dioxide (CO2) content. These properties are frequently controlled by an air handling unit (AHU). AHUs feature supply […]
