Optimization of large heat pumps using ambient air
Large heat pumps in the district heating network are an important element in phasing out fossil fuels. Since the electricity production subsidy for district heating plants in Denmark is no longer available, the district heating plants are experiencing a pressure on the district heating price, which challenges the competitiveness. A heat pump using ambient air as a heat source is a flexible and simple solution, since ambient air is available everywhere, and it is less expensive to install compared to other heat sources.
However, using air as a heat source presents som challenges in terms of frosting of the evaporator and noise. Problems regarding frosting and defrosting of the evaporator pose a risk in terms of operational failures and have a significant influence on the energy efficiency of the heat pump.
The purpose of the project is to optimize and develop the evaporator design and control of the heat pump in realtion to frosting, defrosting and noise.
