Abstract
The processes occurring in an apartment heating can be very different in comparison with a standard laboratory test and the SEDBUK of a boiler can be very far from actual seasonal efficiencies of the same boiler in different heating plants The cyclical efficiency of traditional and condensing boilers can be mathematically defined by its experimental efficiency at full load, for a given return water temperature and by its experimental stand-by losses, considering not only the boiler but its actual regulation system too. To simulate a boiler in a domestic heating plant and to calculate its seasonal efficiency a sinusoidal variation of loads during the season, from zero to a maximum value, can be assumed.Pubblicazioni consigliate
