DESIGN AND LABORATORY TESTING OF A PORTABLE THERMOELECTRIC CALORIMETER FOR MEASURING HEAT FLOW THROUGH WALLS.

Author(s) : KIRCHNER R. P., SAMTANEY R.

Summary

THE CALORIMETER IS AN INSULATED RECTANGULAR BOX THAT IS PLACED FLUSH AGAINST THE INTERIOR SURFACE OF A BUILDING WALL AND MEASURES WALL HEAT FLOW USING A CONTROL CHAMBER. THE CONTROL CHAMBER IS KEPT AT ESSENTIALLY ROOM TEMPERATURE AND THE HEAT FLOW THROUGH THE BUILDING WALL IS RELATED TO THE HEAT FLOW THROUGH THE CONTROL CHAMBER. THE WALL THERMAL RESISTANCE IS DETERMINED FROM THE HEAT FLOW AND THE WALL TEMPERATURE DIFFERENCE DATA. TWO COMPUTER SIMULATIONS, WHICH WERE USED TO PREDICT THE HEAT FLUX VALUES, WERE IN GOOD AGREEMENT WITH EXPERIMENTAL RESULTS. IT WAS CONCLUDED FROM THE LABORATORY TESTS THAT THE THERMOELECTRIC CALORIMETER IS A POTENTIALLY VIABLE AND USEFUL TOOL FOR THE IN SITU MEASUREMENT OF WALL THERMAL RESISTANCE FOR SUMMER HEAT GAIN CONDITIONS.
