• Time

• Budget

• Quality

• Risk

… Management

• Energy bills

• Interviews

• Measurements

• Climate data

• Previous reports

• Defect database / complete data losses

Examples:

• Gap of Data

• Winter/summer time switch

• Different time zone formatting

“Bridging the gap”

• Find defect in the data base

• Talk intensively to the client

• Interpolation for small gaps

• Build up suitable methods/tools

Process

Main Energy Consumer

• Retort, steam tunnel and filling

  —> High energy saving potential especially for the retort (59 %)

C.U.T come up time

1. Before working on a topic: Get information about the fundamentals

   —> Example Retort Sterilization: Heat recovery

   —> Understand the economic impacts of the measure

1. Quantify your results

   —> Example: Energy balance (holding time and come up time)

   —> Find the key variables to optimize the energy consumption

1. Idea of optimization

   —> Example: Motivation to keep pouches hot —> Idea of insulation

   —> Example: Retort: Inter-process heat recovery by Chunk’s water, Mixer, Gravy

2. Quantify potential of the idea

   —> Example: New energy demand

3. Optimizing control

   —> Example: New energy demand

4. Calculate monetary savings for the implementation of the optimization potential

• Inform the client about actual energy saving potentials

• Report can be a presentation

• Rank your energy efficiency actions by quantitative statements

• Discuss where to go into details

• Protocol the results of the discussion

• Sankey Diagrams

• Energy perfomance indicators (EnPIs) in a water fall diagram

• Typical Software Environments used for modelling physical systems

• Examples: Excel and VBA, MATLAB and Simulink, Dymola

Quick Shots

Example: Insulation box shows simple testing

• Temperature measurement

• Clock

• Insulationbox

• Hot water

Experiment can be done in a kitchen

Complex prototypes

Example: Hybrid heating system for waste heat utilization and demand response

• Implementation is a project for itself

• Cost and time plan

• Project planning on basis of simulation and/or testing
