Lämpöjakelupiste

Lämpöjakelupiste is a Finnish term that translates to "heat distribution point" or "heating substation." It refers to a facility or location within a district heating or centralized heating system where heat is transferred from a primary source to a secondary distribution network. This point is crucial for managing and delivering thermal energy to consumers.

In a typical district heating system, a central plant generates heat, often through burning biomass, fossil fuels, or utilizing waste heat. This heat is then transported via insulated pipelines to various locations. The lämpöjakelupiste is where this high-temperature, high-pressure primary heat is converted into a usable form for the end-user's building or a local block of buildings.

At the lämpöjakelupiste, a heat exchanger is the key component. It allows for the transfer of thermal energy from the primary network's water to the secondary network's water without the two fluids mixing. This process typically reduces the temperature and pressure to levels suitable for the building's internal heating and hot water systems. The substation also includes control valves, pumps, and measurement devices to regulate the flow and temperature of the heat being distributed, ensuring efficient and safe operation. Essentially, it acts as an interface, adapting the main heat supply to the specific needs of the local consumers.
