Flexible Energy Optimized Split Condenser Ammonia Heat Pump (FOSCAP)
The objective of the project is to improve the efficiency of ammonia heat pumps with up to 30 % by use of a novel heat exchanger technology, i.e. the condenser is split. This also adds the possibility to supply some of the water at a higher temperature as will be advantageous in many applications. The system can be generalized to other refrigerants.
Today, ammonia heat pumps are constructed with an oversized condenser unit, compared with the design capacity, to achieve low temperature approaches. By splitting the condenser into two separate heat exchanges, the low temperature approaches can be maintained and the total heat transfer area is reduced or the design capacity is raised. The concept is proven in a test unit in a PSO project. The concept and other potential improvements found during the PSO project are expected to show a potential efficiency improvement of up to 30 %. The split condenser concept makes it possible to increase the ammonia heat pump efficiency without increasing the cost of components, compared with present solutions. The concept also makes heat pump solutions suitable for a broader range of temperature requirements without the necessity of more expensive components. The flexible design can contribute to cheaper custom solutions and hereby increase the possible applications for the ammonia heat pump. Hence, the concept contribute to the electrification of heat production in all sectors in an energy efficient and cost effective manner. The industrial partners will differentiate themselves from their turnover and export volume.
