A STUDY OF HEAT AND MASS TRANSFER THROUGH A DOORWAY IN A TRADITIONALLY BUILT HOUSE.

Author(s) : RIFFAT S. B.

Summary

AIRFLOW RATES BETWEEN THE 2 FLOORS WERE MEASURED USING A TRACER GAS AND THE TEMPERATURES AT VARIOUS POINTS ON EACH FLOOR WERE MEASURED. THE LOWER FLOOR WAS HEATED TO VARIOUS TEMPERATURES IN THE RANGE OF 291 TO 308 K (18 TO 35 DEG C). THE UPPER FLOOR WAS UNHEATED. THE HEAT AND MASS FLOW RATES BETWEEN THE 2 FLOORS WERE CALCULATED. RESULTS WERE COMPARED WITH VALUES PREDICTED BY EXISTING ALGORITHMS FOR TWO ZONE ENCLOSURES. THE MASS FLOW RATE AND COEFFICIENT OF DISCHARGE FOR THE DOORWAY WERE FOUND TO BE FUNCTIONS OF THE TEMPERATURE DIFFERENCE BETWEEN THE FLOORS OF THE HOUSE.
