Optimizing the pressure in the cooling system
Modernization of the cooling system makes it possible to achieve remarkable savings in facilities where production processes require cooling – e.g. in food industry. From the point of view of our engineers, cooling of the products and storage chambers seems to be an interesting area to perform analysis.
After carrying out the analysis in one of the facilities operating in food industry, it turned out that the modification of the cooling system of the storage chambers, aimed at gradual arriving at the target temperature and achieving the precise control of the freezing temperature of the final product, was worthwhile.
Storage chamber required the evaporation temperature of -27 ° C, while the cooling compressors were set to work up to the evaporation temperature of -42 ° C. Such cooling system operation is not effective.
DBE suggested introducing yet another, intermediate cooling compressor with the evaporation temperature of -37 ° C, which would reduce the power consumed by the entire compressor system.
Modernization combined with a prolonged, controlled storage of products in the cooling tunnel resulted in the average annual savings of approximately 800 MWh of electricity, with a payback period of less than 7 years.

In 2014 the R&D department started to work in our company. We design solutions to improve energy efficiency in industry.
On 22 June 2016, DB Energy signed an agreement with the National Centre for Research and Development to co-finance R&D work for a project called "Development of an innovative drive diagnostics system (DiagSys) based on electrical signal measurements characteristic of mechanical damage to rotating machine components, together with a specialized analyzer of machine operating status and efficiency (APPS 3)".
The project is financed under the Intelligent Development Operational Programme 2014-2020, under sub-measure 1.1.1. "Industrial research and development work carried out by enterprises". No. of the competition: 1/1.1.1/2015. Value of the project 5 974 021.85 PLN. Value of co-financing 3,727,676.11 PLN.
The aim is to develop a system for the diagnosis of rotating machines (DiagSys system), which will be based on the use of power measurements and on-line access to an expert database.
