Principles of system integration
SHIP WS Brussels 15th March 2013
Development of branch concepts (calculation tool) for
energy efficiency and integration of solar process heat
in the food and beverage industry in Austria
Identification measure and integration concepts which are
typical for the food and drink sector and can be
transferred to other companies
Branch concept SolarFoods (www.solarfoods.at/dokuwiki) Design tool for solar integration:
Guidelines for the sub-sectors
Roadmap for solar process heat in the food and drink industry in Austria
Branch concept : SolarFoods

Integration on supply level – hot water
Feed-in solar energy in heating circuit
High set temperature
Simple system integration
Small number of system layouts

Lesson learned
Advantage for solar integration:
• Heating demand of process between 30°C and 150°C for
flat plate and vacuum tube collectors
• Best: constant load profiles over 7 days a week
• Implementation into distribution network (with storage)
• Heating demand during the day
• Existing distribution network on hot water (for flat plate and
vacuum tube collectors)
• Simple integration on the process side
Disadvantage for solar integration:
• Strong fluctuations on the demand side
• Production during night (larger storage)
• Static conditions of the buildings/no space on the ground
• Existing waste heat at similar temperature level (eg waste
heat from cooling devices)

GREENFOODS
The overall objective to lead the European food and
beverage industry to high energy efficiency and
reduction of fossil carbon emissions in order to
ensure and foster the world wide competitiveness,
improve the security of energy supply and guarantee
the sustainable production in Europe.
GREENFOODS will mainly address dairies, the meat
industry, drink industry (breweries and fruit juice),
bakeries, baby food, cereal producer, animal food
and the fish industry.
14 partners from Germany, United Kingdom, Spain,
Poland and Austria
Project start: April 2013
