Building thermal characteristic simulation under heating condition

Establishes the dynamic mathematic models for the physical model of a typical room.Through the MATLAB/Simulink simulation, analyses the effect of outdoor temperature, solar radiation, wind speed and supply water temperature on the delay characteristics of the heating load and indoor temperature. The results show that the solar radiation has great effect on the heating load delay. The change of supply water temperature has almost no effect on the delay characteristics of heating load. The increase of wind speed has little effect on the delay of heating load in the building with good sealing performance.
