A large compartment for seawater enables HOFOR to increase its production of district cooling while still more costumers join the utility company’s district cooling system
“In order to utilise the cooling station in Adelgade most efficiently, we have built a compartment for seawater near the pier at the end of Sankt Annæ Square. We are talking about a larger investment. However, the investment will also secure a more efficient and greener production of district cooling in the years to come”, explains Henrik Lorentsen Bøgeskov, who is the Manager for district cooling at HOFOR.
The new installation has meant an increase in efficiency at the cooling station in Tietgensgade from 21 MW to 46 MW.
5,715 kW new costumers
In 2016 alone, new costumers equivalent to 5,715 kW have joined HOFOR’s district cooling system. This means that the constructional expansion of the cooling production in the cooling station needs a larger amount of seawater.
– Previously, the cooling station absorbed seawater directly from the harbour but with the new compartment, the water is filtered and pumped into the station. This means that the many machines at the station will be able to do their absolute best, as the volume of water under pressure is able to increase significantly compared to a similar pipeline where the water is absorbed, says Henrik Lorentsen Bøgeskov.
