Description

Barriers for integration of solar heat and heat pumps in industrial processes exist, due to high investment costs, lack of experience, missing integration schemes and planning guidelines or lack of knowledge about technological developments. Within the project "EnPro" barriers should be reduced for manufacturers, users and planners through the creation of supportive measures for the integration of both technologies in an efficient and cost effective way. Therefore case studies in food, paper, metal production and processing, laundries and insulation industry are carried out. Based on these case studies, generalized integration schemes are developed and technical-economic assessments performed. This knowledge is shared to the users in the context of planning directives, consisting of guidelines and rating tools.

Case studies

In the framework of the project 12 case studies were carried out in the following 5 different industry sectors:

Subsection DA food Subsection DC insulation¹ Subsection DS laundry² Subsection DJ metals Subsection DC paper

¹ Within the EnPro project insulating material from chemical extraction is considered. Therefore you will be passed to the Subsection DG chemicals, where you find the relevant information in the section “polystyrene”.

² Due to cleaning of textiles is a process step in textile industry, you will be passed to the Subsection DC textiles. Data enhanced in the EnPro project refers to laundries in general, as well as to the unit operations “Washing/Rinsing”, “Drying”, "Finishing" and "Ironing/calendering".

Planning directives

In the framework of the project planning directives constiting of a guideline and an evaluation tool were developed.

Guideline

The EnPro Guideline describes in detail how industrial company can increase their share of renewable process heat by solar thermal collectors and heat pumps (currently available in German only).

  • Description of heat pumps and solar thermal heat
  • Process analysis to describe the current situation
  • Optimization of energy efficiency on process and system level
  • Integration of heat pumps, solar thermal energy and combined systems
  • Ideas how to integrate renewable process heat
  • Techno-economic assessment
  • Funding for solar thermal energy and heat pumps

Evaluation tool

This tool has been developed during the project to assist auditors, planners, operators and decision makers in self-assessment, benchmarking, design, calculation, optimisation and simulation. The EnPro tool enabels a technical-economic assessment for the integration of solar heat and/or heat pump in industrial processes from food, metal, paper production, laundries and insulation industry.

Decision tree

Following the methodology of EnPro the decision tree supports the user in the identification of possible integration concepts (parallel - P, serial – S1/S2/S3, monovalent – WP/ST). Starting with the information, whether a backup system is necessary in the supply system, an available heat source for the heat pump influences the selection of an appropriate concept significantly. Anyhow, the decision tree is a basis, a detailed evaluation of the possibilities is the next step, supported by the EnPro-Tool.

Integration concepts

The integration concepts developed in EnPro describe how solar thermal heat, heat pumps and their combination are integrated into an industry company. Die integration concepts are based on a modular structure.
