Di. Masse et al., A MOBILE TEST RIG FOR DETERMINING THE AIR LEAKAGE CHARACTERISTICS OF FARM-BUILDINGS, Canadian agricultural engineering, 36(3), 1994, pp. 185-188
A mobile test rig to determine the air leakage characteristics of farm
buildings was developed, constructed, and tested. This rig consisted
of a trailer mounted 1.2 m diameter vane axial fan with a rated capaci
ty of 14 m3/s at a static pressure of 60 Pa and an adjustable duct-to-
building adapter. Air flow was measured using 20 Pitot tubes located i
n the duct. Initial tests on two dairy barns indicated air leakage rat
es in the order of 5 and 11 air changes per hour at a pressure differe
ntial across the building envelopes of 20 Pa.
