Summary

THE PAPER DESCRIBES A SIMPLIFIED PROCEDURE TO PREDICT HEATING LOAD FOR THE GIVEN ROOM AIR TEMPERATURE IN A DYNAMIC SITUATION. WITH INTERMITTENT HEATING THE ACCURACY OF THE PREDICTED LOAD AND ROOM TEMPERATURE GREATLY DEPEND BOTH ON THE CALCULATING TIME INTERVAL AND THE APPROPRIATE MODELLING OF THE MUTUAL RADIANT HEAT EXCHANGES BETWEEN INTERNAL SURFACES. THE SUCCESSIVE INTEGRATION METHOD HAS AN ADVANTAGE IN SHORTENING THE CALCULATING TIME INTERVAL WITHOUT A SUBSTANTIAL INCREASE OF CALCULATION TIME. BY APPLYING THE ENVIRONMENTAL TEMPERATURE, WHICH COMBINES THE EFFECT OF THE AIR TEMPERATURE AND RADIATION, INSTEAD OF THE ROOM AIR TEMPERATURE, MORE ACCURATE RESULTSCAN BE OBTAINED ON ALL ASPECTS OF THERMAL BEHAVIOUR IN BUILDINGS.
