Heat recovery units for air conditioning are devices specifically designed to improve the efficiency of heating, ventilation and air conditioning (HVAC) systems by recovering and recycling heat from incoming and outgoing air flows. This equipment is installed in the ventilation circuit of a building and its main purpose is to recover energy ...

Following the recommendations of the Air Movement and Control Association (AMCA), the U.S. construction code has decided to include the air curtains installation as an energy saving effective alternative. Thus far, the American construction code IECC 2015 (International Energy Conservation Code) just referred to the recommendation that new ...

How does an EC motor work? The EC (electronically commutated) motor is a synchronous motor powered by an inverter with permanent magnets in an external rotor design. The stator is driven by electronic switches controlled by a microcontroller. The motor needs to be supplied with AC voltage and a DC voltage signal to operate.The mains voltage, ...

The City Council of Konstanz, Germany, has a strong commitment to sustainability and energy efficiency. For this reason, it has incorporated an effective solution against climate control losses in its facilities with a Zen air curtain. This system optimizes the building's energy consumption by minimizing heat loss in winter and maintaining a ...
