København og omegn

Ambient air has been used in several cases as heat source for large-scale heat pumps to supply district heating. The two largest heat pumps in Denmark have a capacity of 4.4 MW. We would like to know how much larger the capacity can be and how the outgoing air flow influences the incoming flow.

The purpose of this investigation is to identify the capacity limit and characteristics of ambient air used as heat source in city areas, such as Nordhavn. Nordhavn is a new city district in Copenhagen. It will gradually be converted from a rural harbour area to a demonstration of a sustainable city district of the future, featuring environmental responsibility. It is expected that Nordhavn will have 40,000 inhabitants and 40,000 jobs distributed over a floor area of 3.5 million m2 by 2060. For this purpose, ambient air shall be analysed and its potential use as heat source for a heat pump be assessed.

The aim of this project is to analyse the required air volume that is needed for different heat pump sizes. Heat pumps may be varied in size, number and location. In addition, the impact of the outgoing air flow on the incoming flow shall be investigated. This is important, since the outflowing air has a lower temperature, which may influence the performance of the heat pump negatively. The flow patterns may be influenced by ambient conditions such as wind speed, wind direction, ambient temperature and others. The following may be investigated:

- Impact area/volume of ambient air for different heat pump sizes

- Distance between the installations of several heat pumps without influencing each other’s inlet air flows

- The influence of the outgoing air flow on the incoming air

- Effects of changing ambient conditions on the flow patterns

- Determination of maximum heat pump capacities

CFD-analysis shall be used for modelling the fans of the heat pumps.
