THE EFFECT OF TRACER GAS ON THE ACCURACY OF AIR-CHANGE MEASUREMENTS IN BUILDINGS.

Author(s) : SHAW C. Y.

Summary

THIS STUDY COMPARES THE AIR-CHANGE RATES MEASURED USING THE DECAY METHOD WITH SEVERAL DIFFERENT TRACER GASES (CH4 , CO, CO2, N2 O, SF6 ). THE MEASUREMENTS WERE CONDUCTED IN A TIGHTLY SEALED ROOM WHERE CONSTANT AIR-LEAKAGE RATES, RANGING FROM 0.05 TO 1 AIR CHANGE PER HOUR, COULD BE MAINTAINED USING AN EXHAUST FAN. THE AGREEMENT BETWEEN TRACER-GAS MEASUREMENTS AND MEASURED FLOW RATES OF THE EXHAUST FAN WAS VERY GOOD FOR CH4 , CO AND N2 O. IT WAS ALSO SATISFACTORY FOR CO2 AND SF6 , BUT THE SCATTER IN THEIR DATA WAS MUCH GREATER.
