GEA has been studying integrating high-temperature CO2 heat pumps with conventional heaters to preheat the process air of spray-drying systems since 2019.
The Annex 58 high-temperature heat pump project has reviewed systems supplying temperatures over 100°C and found refrigerants like CO2, water, hydrocarbons, helium and ammonia being used.
The third high-temperature heat pump symposium will include presentations, panels and site visits, in Copenhagen on March 29-30.
Nordic Green Procurement Criteria invokes precautionary principle in evaluating HFOs’ potential risks, webinar speakers say.
The new courses cover ammonia, CO2, and how heat pumps can be used to increase energy efficiency.
A conference taking place at the Danish Technological Institute (DTI) in Taastrup, Denmark will focus on challenges and opportunities in the supermarket sector.
The Danish Technological Institute (DTI) supplies complete CO2 training courses combining theory and most importantly hands-on training. Denmark continues to lead Europe in CO2 transcritical store installations and DTI is well placed to ensure refrigeration professionals keep up with the highly evolved market.
It was clear at ATMOEurope 2015 that suppliers and end users alike are already charting new territory in order to maximise overall system and building energy efficiency. Integrated CO2 refrigeration systems for CVS layouts from Carel and EPTA Deutschland, CO2 condensing units and the need to scale down solutions for smaller formats were all on topic.
DTI at Gustav Lorentzen 2014: can ice storage and Vortex Flow Sensors improve CO2 system efficiency?
The Danish Technological Institute (DTI) presented two papers on topics related to CO2 refrigeration systems at the 2014 Gustav Lorentzen Conference on Natural Refrigerants held in China from 31 August – 2 September. In the first presentation, ice storage for a transcritical refrigeration system is suggested in order to achieve greater energy savings in warmer climates, and flexible power consumption.
