for multi-family buildings with flat station system
In multi-family houses, it is typical to have a district heating substation in the basement supplying the flats with hot water according to the demand for heat and hot water. A decentralized heating system comprises an installation with flat stations built into each apartment. These are then supplied with hot water from the central substation in the basement. Making the flat stations comparable to one-family house substations.
There are generally three application types that are for multi-family buildings with a flat station system:
Depending on the choice of the flat station there may be a need for a basement substation to regulate either the supply temperature or the pressure levels. The basement substation applications are:
The design of the secondary heating system, the heat exchanger, and the control equipment on the primary DH network supply side are directly related to the successful operation of district heating substations.The variations in consumption from hour to hour and day to day cause the differential pressure to fluctuate markedly as the flow varies in the primary supply. This affects control of the supply to the substation in the building.
When connecting a building to district heating, many options are available for heating the building and for the preparation of domestic hot water, and with each application there are specific benefits and limitations.
The best solution comes from matching the system infrastructure and design with the available supply of energy sources, building type and individual needs.
