Calculation method of intermittent heating load

Taking residential and office buildings in some typical cities in the hot summer and cold winter zone, the cold zone and the severe cold zone as the research objects, simulates and analyses the influences of the building envelope, the air changes and the two modes of radiator heating and floor radiant heating on the intermittent heating load by DeST and DesignBuilder software respectively. Gives the heating load additional factor of the intermittent heating compared with the continuous heating, and determines an appropriate intermittent heating mode. The results show that the influence of the area ratio of window to wall on the intermittent heating load is negligible; the intermittent heating load additional factor increases by about five percent when the air changes increases 0.5 h-1; the intermittent heating load additional factor using floor radiant heating is lower by three percent to ten percent than that using radiator heating.
