The DKV conference is one of the main conferences for the refrigeration and heating industry in Germany, Switzerland and Austria and attracts more than 600 participants.
A total of 113 presentations have been held in the following 5 categories: cryogenics, basic principles and materials of refrigeration and heat transfer, component development for heating and refrigeration technologies, refrigeration applications and air conditioning and heat pump applications including high-temperature heat pumps, trends and energy systems of the future.
AIT’s contribution focuses on heat pumps for steam generation. Steam serves as an efficient medium for heat transfer and as a reaction agent. Depending on the sector, up to 40% of the total heat requirement is accounted for by low-pressure steam at around 3-5 bar (134-152°C). If heat pumps are used to generate steam instead of natural gas, significant primary energy and CO2 emission savings can be achieved.
These heat pumps become increasingly important for industrial companies as a contribution to achieving global climate targets. Also, heat pumps that generate steam can be integrated easily into existing steam supply networks in industrial companies. In this work, different configurations of compression heat pumps for steam supply are compared in numerical simulations and evaluated with regards to efficiency, complexity and energy and emission savings
