HVLS WORKING PRINCIPLES

HOW DOES IT WORK IN SUMMER?

  1. Adiabatic evaporators bring in fresh outdoor air through the roof/skylights. Simultaneously, they clean, humidify, and cool the air by at least 7°C.
  2. Heat extraction turbines balance external and internal temperatures and expel used and polluted air through the roof. Consistent air rinsing reduces the thermal load by up to 7°C and also removes excess humidity.
  3. Air barriers keep cooled air inside the building by recirculating facility air in a smooth, uniform flow, creating a seal at the doorway. This system ensures environmental separation, reduces door cycles, and increases the life expectancy of cooling and heating systems.
  4. HVLS destratifiers take in conditioned air and ensure its even, high-volume, draught-free distribution with a flow rate of up to 550,000 m3. The circulated air can reduce ambient temperature by up to 7°C.

HOW DOES IT WORK IN WINTER?

  1. Adiabatic evaporators are either inactive or merely supply uncooled outside air.
  2. Ventilation turbines may be limited to prevent heat loss during winter.
  3. Air barriers prevent heated air from escaping the building, ensuring environmental separation, reducing door cycles, and increasing the life expectancy of cooling and heating systems.
  4. HVLS destratifiers pull warm air from just below the roof and gently push it towards the floor at very low speeds. This process mixes the different air layers, achieving a temperature difference of no more than 2°C between the floor and the roof.
  5. Infrared heaters warm the environment indirectly by raising the radiant temperature. Radiation rays touch the skin of employees, as well as floors, machines, materials, and other objects. These surfaces absorb the heat energy and dissipate it into the environment as they warm up, resulting in a comfortably heated space.
