Ammonia heat pump boost for Berlin CHP plant


GERMANY: Johnson Controls has equipped a 700kW Sabroe ammonia heat pump to the Berlin-Buch, CHP plant in Berlin, operated by Vattenfall Europe Wärme AG.

The CHP plant employs a warmth recovery boiler to capture waste heat from an present gasoline turbine to generate heat for the community district heating network. The addition of the Sabroe HeatPAC 104SV warmth pump with solitary-phase reciprocating compressor will strengthen the plant’s district heating ability.

In Berlin, Vattenfall operates the greatest city heating community in Western Europe with close to 1.3 million linked residential models. A overall of 2,000km of pipelines supplies the linked homes with 80 to 135°C warm water which supplies heating and very hot water to related residences. The Buch island community in the north of Berlin supplies a overall of all-around 10,000 residences and 500 person facilities.

“This venture places the power of heat pumps to operate to meet up with strength demands whilst reducing waste, emissions and charges. Importantly heat pumps supply expected heating with out the need for extra gas supplies,” claimed Dave Dorney, vice president & typical supervisor industrial refrigeration at Johnson Controls. 

The diploma of fuel utilisation for the total CHP course of action at Buch is claimed to be about 90%. In addition, the Buch thermal ability station works by using the squander heat from the landfill gas technology from the Schwanebeck landfill in Nauen, 60km west of Buch, and therefore covers up to 20% of the district heating requirement for the Buch heating network.

Sabroe HeatPAC models are based mostly on the Sabroe HPO/HPC/HPX superior-pressure reciprocating compressors obtaining up to 40bar differential pressures and up to 60bar layout pressures. Utilizing ammonia as refrigerant, Sabroe HeatPACs give sizzling h2o at up to 90°C. At Vattenfall, the Sabroe device is running with a COP of 6.5.
