Wpływ zmienności dostarczonej mocy cieplnej na temperaturȩ pomieszczeń ogrzewanych

Heat demand is affected by many factors such as outdoor temperature, solar radiation intensity, wind speed, heat gains from people, lighting and appliances inside the heated space, as well as the walls ability to heat accumulation. Daily variations in weather factors make it necessary to change the thermal power delivered to the building. In this paper the effect of internal temperature changes, depending on the delivered thermal power have been analyzed. First variant assumes constant thermal power delivery equal to the average heat demand, while the second one assumes variable thermal power delivery equal to instantaneous heat demand of the building. Analyses were performed using a simplified method of the heat demand calculations, which allows to estimate it in hourly intervals.
