Why terminals are energy hotspots Airports are among the most energy-intensive buildings in the commercial sector. Vast terminals run 24/7 with high fresh-air requirements, large glass facades, and constantly moving passenger loads. Heating and cooling the ventilation air alone can account for 40-60% of a terminal's HVAC energy. Air-to-air heat recovery is the single highest-return […]
Rotary Heat Recovery Wheel: Sensible and Enthalpy Types
A rotary heat recovery wheel is a rotating honeycomb disc that slowly turns between the supply and exhaust air streams. As it rotates, the wheel absorbs heat from the exhaust air and releases it into the incoming fresh air. In enthalpy wheels, moisture is also transferred, making them ideal for humidity control. How It Works […]
Plate Heat Exchanger: Working Principle, Types and Applications
A plate heat exchanger is one of the most efficient ways to recover thermal energy from exhaust air, process gas, or ventilation streams. It consists of multiple thin metal plates separated by gaskets or formed air gaps, creating alternating channels for the hot and cold streams. Heat moves through the plate material without the two […]
