Modern Ventilation Systems have halfed Electricity Consumption

Energy savings

VengSystem has always paid interest to energy consumption and is today the frontrunner within ventilation systems.

The electricity consumption of a ventilation system depends not solely on the design of the system (diffuse ceiling/wall-/ceiling inlets, negative and positive pressure) but also of the layout in the rooms. Finally also the climate has an impact, hot climate generates higher electricity bill.

With above defined the design of the air outlet, the function of its shutter, the fan and finally the control of the fan have impact on electricity usage.

Below you can view the electricity consumption with different setups. It is clear that you can save considerable energy by selecting the right design.

  • The blue curve shows an air outlet with triac controlled fan and manual shutter.
  • The red curve the manual shutter is replaced with a motorized.
  • The brown curve is with a frequency converter driving a single phase fan
  • The green curve is with a frequency converter driving a three phase fan or an EC / LPC fan

The electricity consumption can be simulated using sophisticated computer software, which uses the climate, dimensions of the room, insulation, type and number of animals, control and set temperature.

With Danish climate the graphs below show the electricity consumption over one year for 200 finishers from 30 to 100 kg using an EC fan outlet and a Hi-Lo outlet.

The Hi-Lo system uses slightly more because the simulation is for one room only. Normally you have several rooms and the self-consumption of the frequency converter is then shared by all rooms.

The electricity consumption to ventilation is as low as 1.86 kWh per finisher produced assuming that you pass 750 pigs through a room with 200 pig places. On top of that you have excellent wind stability and consequently low stress in the pens, which improves the feed conversion ratio.
