lämpöjakopiste

Lämpöjakopiste, often translated as heat distribution point or heat substation, is a key component in district heating systems. Its primary function is to receive heat from a central heating plant, typically via insulated underground pipes, and distribute it to individual buildings or smaller zones within a larger area. This allows for efficient and centralized management of heating and hot water supply.

The lämpöjakopiste contains essential equipment for heat exchange, control, and metering. A heat exchanger is crucial; it transfers heat from the primary circuit (the hot water coming from the central plant) to the secondary circuit (the water circulating within the building or zone). This prevents the direct mixing of water from the central system and the local network. Control valves and sensors regulate the temperature and flow of water, ensuring consistent and optimal heating according to demand.

Metering devices within the lämpöjakopiste measure the amount of heat energy consumed, which is then used for billing purposes. Safety features, such as pressure relief valves, are also integrated to maintain system integrity. The design and capacity of a lämpöjakopiste vary depending on the size of the area it serves and the heating requirements. They are essential for the effective operation of modern district heating networks, contributing to energy efficiency and environmental sustainability by centralizing heat production and distribution.
