PIP3 reduces data centre heat pump electricity costs by using the return pipe instead of the traditional supply pipe. This allows both lower temperature excess heat distribution and utilisation across existing district heating networks.
"The new PIP3-solution is in use in Porvoo in Southern Finland, where the city's largest primary school is heated with 45-50°C water from the return pipe," said Johnny Holmströmm, CEO, Iotoi Oy.
"This increases energy efficiency in the entire district heating network. With this innovation, you can both receive and distribute excess heat via the return pipe."
Historically, district heating networks have used the supply pipe for both excess heat distribution and use, causing the excess heat’s temperature of data centres to raise with heat pumps. The higher the temperature, the more electricity is required which also effects profitability.
