An influence of weather conditions on heat demand in district heating systems

The article deals with the problems of determining heat power in a heating system taking into consideration solar radiation surpluses as well as increase in heat demand resulting from a higher wind speed. It is relatively simple to calculate these surpluses and heat losses for a single building. However, it is much harder or sometimes impossible, to estimate heat losses and surpluses related to solar radiation and wind influence for building complexes heated by a heating system. Results of the empirical research of these processes allow to properly, and in advance, steer the work of the heat source or sources feeding the heating system.
