DHWcalc: PROGRAM TO GENERATE DOMESTIC HOT WATER PROFILES WITH STATISTICAL MEANS FOR USER DEFINED CONDITIONS

A program to generate Domestic Hot Water (DHW) profiles has been developed. The generated profiles are text-files, containing a list of flow rate values for each time step. They are used primarily for annual system simulations, but are also suitable to be used for test procedures of laboratory system or component tests. The program distributes DHW draw-offs throughout the year with statistical means, according to a probability function. Reference conditions for the draw-offs (flow rates, draw-off periods, etc.) and reference conditions for the probability function (daily probabilities for draw-offs etc.), can be set by the user, as well as general profile parameters like time step period and mean daily draw-off volume. The program can be downloaded free of charge at the web page: www.solar.uni-kassel.de.
