Project - Energy efficient ammonia heatpump
Energy efficient Ammonia Heatpump
Project started April 1st 2011. Project ended March 30th 2013.
Purpose & objetives of project
The purpose of the projekt is to develop a standard ammonia heatpump, where the efficiency (COP) will be improved up to 20% in comparison to traditional systems. This can be achieved by regulating the large temperature variations on the kondensator- and evaporator side, respectively. If the large variation only occurs in on of the exchangers, the level of improvement will be reduced. The increase in efficiency occurs through a reduced temperatureapproach in the heatexchangers, and through attaching a pump in connection to a flooded evaporator.
The project is divided into five phases:
- Simulationmodel for VP
- Management & control
- Building of pilot heatpump
- Test of pilot heatpump
- Installation of final design at a client (proof of content)
- Danish Technological Institute
- Alfa Laval
- Grundfos Management A/S
The project was funded by EUDP.
