Lever 1
KappaQ-Energy Design

 

The first lever, "Design", describes the influence of the design of the solution on the energy efficiency of the entire air treatment system. 

Energy is required to operate exhaust air, process air and ventilation systems. But the amount of energy required can be reduced significantly. This is all about energy-efficient system planning. Our experience has shown that inadequate consideration of energy efficiency in the solution finding and plant design phase cannot be made up for. It is therefore all the more important to take energy consumption into account as early as the planning phase.

Once the optimal ventilation and air conditioning solution has been determined, the correct design and dimensioning is crucial for optimal energy efficiency. An incorrect design can lead to an improper throughput of air. The result is an undersupply due to insufficient capacity. In the case of overdimensioning, incorrect planning leads to oversupply. First of all, such a system is not functional, and secondly, a lot of energy is consumed unnecessarily.

Our recommendation

 

  • Use the experience that exists within your company. When planning, draw on the know-how and solution concepts of external partners.
  • Dimension your ventilation and air conditioning system accurately. Here, too, you can benefit from the know-how of external partners.
  • Always evaluate individual solution concepts holistically. This means that, in addition to the basic function, the expected energy consumption is always taken into account. To do this, draw up a list of the current energy requirements and compare these with the investment costs.

Case study
energy-efficient
overall concept

A customer asked us to plan a process exhaust air system to capture and extract emissions from their annealing bath. Various solutions had already been proposed according to the requirements. The design and dimensioning of the offered solutions were based on the experience of our customer and the providers involved. It already became clear to us during the first inspection that the quantity and the surge-like spread of the emission clouds made dimensioning on the basis of prior experience impossible.

Therefore, in the first step, we tried to determine the emission characteristics and quantity. However, there were no analytical tools suited to this. That's why we developed the Kappa Video Fluid Dynamic (VFD) software. It is based on video recordings that can be used to determine the speed, extent, and quantities of visible emissions. Once the results are obtained, the required collection and extraction can be correctly determined.

Results

 

  • It was possible to optimize the detection with the Kappa VFD analysis of the mass flows. This led to a reduction of the required extraction volume flow by 34% (compared to the existing design and to dimensionizing according to VDI standards)
  • The power consumption required to operate the air treatment system was reduced by 334,850 kWh per year. This corresponds to energy savings of 53%.
  • That is 245,100 kilograms of CO2 It corresponds to the amount of CO2 that 19,600 fully grown beech trees filter from the atmosphere each year.
