A room ventilation and heat transfer experimental facility

Energy-efficient building design often makes use of night-time ventilation or thermal slab activation. The quality of the design tools used depends on the quality of the empirical valuesused within them such as heat transfer coefficients. Thus, an experimental facility for investigationof room ventilation and indoor heattransfer has been built at Biberach University ofApplied Sciences in Germany. lnitial tests havebeen conducted investigating natural convectionheat transfer with an electrical heating elementon the floor. The facility, its instrumentation andinitial experimental results are presented in this paper.
