Lämpöjakelupisteisiin

Lämpöjakelupisteisiin, known in English as heat distribution points or thermal distribution points, are crucial components in district heating and cooling systems. These are essentially substations where heat or cold is transferred from the main distribution network to individual buildings or smaller local networks. Their primary function is to facilitate the safe and efficient exchange of thermal energy.

Within a lämpöjakelupiste, a heat exchanger typically plays a central role. This device separates the primary circuit of the district heating or cooling network from the secondary circuit of the building or local network. This separation prevents direct mixing of the fluids and allows for pressure and temperature adjustments to be made. The building's own heating or cooling system, which circulates water through radiators, underfloor heating, or cooling coils, is connected to the secondary side of the heat exchanger.

Lämpöjakelupisteisiin also incorporate control and safety mechanisms. These include valves for regulating flow, temperature and pressure sensors, and safety devices like pressure relief valves. Automated control systems monitor the system's performance and adjust heat transfer based on demand and network conditions. This ensures optimal energy delivery and prevents overheating or overcooling. The design and capacity of a lämpöjakelupiste are tailored to the specific heating or cooling load of the connected property. They are essential for the effective operation of modern urban thermal energy infrastructure.
