The problems of space heating in dwellings and municipal buildings, connected to district heating
Santrauka
The qualitative adjustment is used in district heating networks until the temperature of water is higher than 70°C. When the outside air becomes warmer the temperature could be less than 70°C, but it is left constant and equal 70°C because the hot water for sanitary usage and other purposes is healed by the water from district heating networks. For this reason the houses are overheated and the considerable amount of heal is lost uselessly. It is shown by the newly deduced formulae and by calculations, which were provided on the basis of mentioned formulae. Also is suggested to provide the qualitative adjustment in district heating systems the all heating season and is proved that in such case is possible to produce enough hot water. After the finishing of heating season the temperature of water in district network should be risen again until 70°C.
