Summary
Aalborg CSP has revealed plans to install a large-scale heat pump for wastewater to optimize a green district heating system operated by E.ON Denmark, a unit of German energy company E.ON, in Frederikssund, Denmark.
“The order for E.ON Denmark consists of turnkey contract for a heat pump with associated exchanger, piping and purification system, which will be extracting the energy from the treated wastewater before it is subsequently discharged into the local environment at Roskilde Fjord,” Aalborg CSP said in a statement. “The heat pump itself, which applies the natural refrigerant ammonia (to be completely renewable and nontoxic), will have a maximum output of approx. 2,500 kW.”
The Danish renewable energy company said the heat pump will be set up at a local wastewater treatment plant. It claimed that it will have a high coefficient of performance (COP), with the wastewater temperature varying throughout the year.
