Sabroe NH3 heat pump in seawater DH scheme

GERMANY: Johnson Controls is providing its Sabroe DualPAC ammonia heat pump to a project using water from the Baltic Sea to generate green energy.

The two-stage heat pump system will provide part of the heat supply to a new heating network in the municipality of Neustadt in Holstein, Germany.

The Sabroe DualPAC was manufactured at Johnson Controls’ plant in Denmark, is at the heart of a pioneering project by the Neustadt municipality and is being funded by the Federal Ministry for Economic Affairs and Climate Protection.

The heat pump features a modular system to enable high temperature lifts. It will use the sea water to generate a heating output of up to 700kW. During the winter months when the water is colder, it will extract around 500kW of heat from the water, which is raised to a higher temperature then fed into the new district heating network. At peak times, it will be supplemented by heat from a nearby waste incineration plant and a heat storage facility.

This seawater solution is said to be the first of its kind in Germany on this scale and represents a model for the transformation of heat supply.
