SoProW-Demo – Demonstration of Energy Efficiency and Solar Process Heat in Industrial Laundries
Industrial washing machine with hot water, cold water and steam connection.
Storage of a solar plant which provides heat for additional boiler water, boiler feed water and washing machines.
Potential integration points for solar heat in industrial laundries on supply and process level.
One important research topic of the Fraunhofer ISE deals with solar process heat which aims at an optimized integration of solar thermal energy into industrial production processes. The goal is an increase of energy efficiency in industrial companies through improved process management and technologically, economically and ecologically reasonable integration of renewable energies. As part of the SoProW-Demo, the combination of energy efficiency measures and solar thermal energy is analyzed, optimized and demonstrated in three industrial laundry services in Germany.
Within the realm of solar process heat, the project SoProW-Demo aims for a detailed analysis, optimization and demonstration of energy efficiency measures combined with solar thermal energy integration using three examples industrial laundry services in Germany.
To begin with, process monitoring for real-time registration and balancing of the complete water and energy consumption was installed. The registered data is used to determine possible heat recovery measures using the pinch analysis and to quantify their effect on potential integration points of solar process heat. Overall concepts for energy efficiency and solar thermal energy are developed for the companies as part of technological-economic modeling. In order to implement as many of the suggested measures as possible in the laundry service companies, they are continuously supported by the Fraunhofer ISE, for example during the call for tender for the efficiency measures and solar installations. After the implementation of the measures, the process monitoring is supplemented by scientific monitoring of the solar systems. The monitoring activities are used to determine the annual characteristic values of the solar systems and to examine the effectiveness of the energy efficiency measures. The data is analyzed in particular regarding the interdependencies between heat recovery and solar heat integration.
All project results are published on a website which also serves to distribute the results of the joint project SoProW (FKZ 0325999A, BMWi). SoProW-Demo supplements the prior project SoProW with an analysis of the optimized coupling of energy efficiency and solar thermal energy.
