Heating system for groups of buildings

摘要

In the system, each building has installations which attract heat from the hot fluid which is supplied to it. The supply arrangement consists of a coarse distribution circuit which feeds fluid to heat source installations in which the fluid is heated The installation further incorporates a fine distribution network which connects buildings to the heat source installations and returns the fluid, from which heat has been extracted, to the heat sources. The fluid used can be water at a temperature of 45 to 55 degree C. Hot water taps are at the same time supplied with water at a temperature of around 60 degree C.
