Abstract: Investigations of domestic hot water (DHW) consumption and the consumption profiles have been carried out in many countries. Over-dimensioning of systems and equipment has been observed in the US. In Estonia it is customary to determine DHW design flow rates for schools and children's institutions proceeding from the sum of the standard flow rates. The design flow rate calculated by standard EVS 835:2003 for ordinary schools and children's institutions are considerably bigger than the actually measured ones. For determining the design flow rates for the determination of the water heating devices for schools, children's institutions, office and administrative buildings calculation formulas are recommended. By the recommended formulas the design flow rates for ordinary schools are approximately 1…1.2 times smaller than those calculated by the EVS standard, 1.1…2.1 times smaller for children's institutions and 1.2…2.2 times smaller for office buildings. Recommended !
calculation formulas reduce over-dimensioning both the DHW instantaneous heat exchangers and the flow rates of the district heating network.
Keywords: DHW consumption, determining the design flow rates, schools, kindergartens, office buildings.
