Monitoring of energy costs as a result of reduced heat exchanger efficiency and optimisation possibilities
This project has developed and tested a new concept for heat exchanger efficiency monitoring that on-line calculates and visualises the energy costs resulting from fouling. This makes it possible to improve and maintain the heat exchanger efficiency through changed system design and maintenance strategy of the water system.
The objective of this project is to reduce the effects of fouling in industrial refrigeration systems. This will be implemented partly through the development and testing of a new concept for heat exchanger efficiency monitoring that on-line calculates and visualises the energy costs resulting from fouling. In addition, the project will seek to improve and maintain the heat exchanger efficiency through changed system design and maintenance strategy of the water system. Besides energy monitoring, the monitoring of the heat exchanger efficiency will at the same time be used as indicator of the condition of the water system and the quality of the maintenance as well as an indicator of when the heat exchanger should be cleaned. Lacking control and visibility of heat exchanger efficiency is believed to be a substantial barrier to utilising the optimisation potential. The project results will give the operating staff in each individual company an applicable tool to easily carry out cost benefit analyses of when it is best to clean the exchanger. Today, the exchangers are at best cleaned periodically or in worst case when performance clearly is too low. This project involves the most important Danish actors in the segment and covers the entire supply chain from product suppliers over energy advisors to the end users
