CoolShaft combined smoke and day to day shaft ventilation system
Description

A combined smoke and day-to-day shaft ventilation system which uses evaporative cooling technology to provide active pre-cooling of the incoming air, without compromising the ability of the shaft system to ventilate the common area in a fire and with exceptionally low energy consumption. It is suitable for all types of smoke ventilation system and building.

Features:

  • Cooling of corridors: Whereas basic day-to-day ventilation systems for common corridors and lobbies use outside air to ventilate the space, the system provides active cooling of incoming air, providing highly desirable conditions for the residents. If the ambient air is 30°C or above, the supply air can be cooled down adiabatically by at least 10°C. In general, the hotter the weather, the more efficient the cooling is.
  • Economical: Offers cooling that is up to 7 times more economical than conventional air conditioning systems, with lower initial costs. Runs much of the year in free cooling mode, with evaporative cooling brought on-line when temperatures rise. CoolShaft units consume only around only around 1 kW and 50 litres of water per 10,000 m³/h of supplied air, equivalent to more than 30 kW cooling power, depending on the configuration chosen.
  • Low energy use: Evaporative cooling is up to 90% efficient. Only needs a small quantity of electricity for the fan that circulates the air and for the water pump.
  • High cooling capacity: One unit can cool multiple floors, and often the complete building, owing to its inherent high cooling capacity.
  • No refrigerants: Free from refrigerants, thus there are no F-gas compliance issues, and there is no need for refrigerant / water pipework in the building.
  • Hygiene certificate. Includes an integrated water quality system and provides safe circulation with temperature control and regular renewal of water to avoid the growth of bacteria and scale. It has been extensively tested and certified hygienically in compliance with VDI 6022 (Hygienic Requirements for Ventilation Systems and Units for Internal Spaces). This is a rigorous standard for air conditioning systems and confirms the high quality of supply air.
  • A space saver: Offers a smaller rooftop footprint and saving on rooftop ductwork compared to conventional air conditioning systems, thereby freeing up space.
  • Lightweight: Much more lightweight than conventional air conditioning systems.
