General description and application

Maximum operating parameters

District heating transfer stations provide the link between district heating suppliers and customers’ systems. They incorp orate the necessary equipment to tailor the supplied heat to the needs of the object premises as specied in the heating supply contract. In this they need to comply with all applicable standards and with the supplier’s technical connection conditions.Indirect connections (in which district heating and in-house systems are hydraulically isolated)incorporate components to separate the systems (heat exchanger), to limit the ow volume to that specied in the contract, regulate the se condary supply temperature and measure the energy consumption. The system described here is a standard type in which one dierent types of applications can be connecte d on the secondary.Thus, this system is especially suitable for biomass applications.

Pipes and pipe ttings, anges P235GH-TC1, C22.8, CuSn5Pb5Zn5-C (RG-5) Heat exchanger 1.4404 with CU brazing compound Fittings CuSn5Pb5Zn5-C (RG-5), ST37.0, EN-GJS-400-18-LT (GGG40.3) Insulation PU-Hardfoam, black, λ = 0,027 W/mK

Hot water drawn from the pipeline of the local or district heating supply company is fed into the station at an appropriate temperature and pressure, which may be higher in winter than in summer.

In the primary supply line this hot water will ow through a shut-o valve and a dirt trap / strainer. The supply and return lines will incorporate a thermometer and a manometer to register the temperature and pressure.

There will also be regulatory equipment in the return lines of the primar y as specied by the circuit design.

The cooled heating water then ows back to the local or district heating supply company via the primary return pipe.

On secondary side dierent types of applications and systems can be connected.
