Self powered Free Cooling System

The Self powered Free Cooling System (SAF Cooling) consists of an improved wind system, which has been coupled with an electric current generator (dynamo, alternator, etc.) making it a thermodynamic machine for producing electric energy and hot. The movement of the windmill-extractor is produced taking advantage of the temperature difference between the inside and outside of an enclosure; Placed the windmill in the evacuation conduit, the hot gases will accelerate the rotary movement, which, in turn, will move the associated current generator. It consists of the following parts:

  • Windmill-extractor.
  • Electric current generator.
  • Vertical axis mill with wing effect.
  • Motorized grille.
  • Control plate
  • Auxiliary batteries.

This new system can be classified in three ways:
“Renewable energy”, because it generates electricity from the natural currents (chimney effect), which is why we could also define it as “Cogeneration” and for its efficient use of the wind we must define it as “Mini-Aeolian Project”.

The outstanding proposals are potentially interesting because of the characteristics that we summarized below:

  • Strategic interest – Reduces the consumption of primary energies.
  • Industrial Interest – It supposes a new industrial and business line, complemented by new products derived from the experience and the evolution of the device.
  • Environmental interest – Increases efficiency and reduces electricity costs and abounds in self-consumption.
  • Cost effective for energy companies that act as agents – Opportunity to manage surplus energy.
  • Air conditioning energy consumption savings of up to 75% in BTS (Telecommunication Base Stations).
  • For Kilowatio consumed of fossil origin, 650 grams of CO2 are emitted, which means that our system reduces CO2 emissions by approximately 4,000 kilos per year for each TBS.

DC FAN SPEED CONTROLER

  • Designed to control DC fans in forced ventilation systems.
  • By means of modulated bandwidth pulses, adjust the speed of the fans according to the temperature.
  • Capable of feeding up to 3 outputs in parallel, with a maximum output current of 0.6A in direct current, in addition to an output signal for a slave unit.
  • The operating curve is fully configurable and defined by the user, as well as stop, start, limit speeds and hysteresis.
  • It has a thermal alarm in the version of NO and NC contacts for connection in remote monitoring systems or in displays.

Applications:

  • Forced ventilation in power units.
  • Thermal alarm.
  • Automated ventilation systems.
