MEASUREMENT OF HEAT AND MASS TRANSFER BETWEEN THE LOWER AND UPPER FLOORS OF A HOUSE.

Author(s) : RIFFAT S. B.

Type of article: Article

Summary

AIR FLOWS BETWEEN THE 2 FLOORS WERE MEASURED USING A SINGLE TRACER GAS TECHNIQUE AND THE TEMPERATURES AT VARIOUS POINTS IN EACH FLOOR WERE MEASURED USING THERMOCOUPLES. THE LOWER FLOOR WAS HEATED TO VARIOUS TEMPERATURES BETWEEN 291-308 K (18-35 DEG C) WHILE THE UPPER FLOOR WAS UNHEATED. DESCRIBES HOW THE MASS AND HEAT FLOWRATES BETWEEN THE 2 FLOORS WERE CALCULATED FROM THE TRACER GAS CONCENTRATIONS AND THE TEMPERATURE DIFFERENCES AND RESULTS COMPARED WITH THE VALUES PREDICTED BY THE EXISTING ALGORITHMS FOR THE 2 ZONE ENCLOSURES. FINDS THAT THE MASS FLOW RATE AND COEFFICIENT OF DISCHARGE FOR THE DOORWAY WERE FUNCTIONS OF THE TEMPERATURE DIFFERENCE BETWEEN THE FLOORS OF THE HOUSE. (INT. BUILD. SERV.
