Convective heat transfer in building energy and thermal load calculations.

Author(s) : FISHER D. E., PEDERSEN C. O.

Summary

Experiments, which were performed over a range of conditions from 3 to 12 air changes per hour in a full scale room, showed that for most room configurations, natural convection film coefficients significantly underpredict the rate of surface convective heat transfer. The new film coefficients were implemented in the BLAST program, an hourly heat-balance-based building energy simulation. The significance of the error incurred by using natural convection film coefficients in a ventilated space was estimated by comparing Blast results obtained with both natural convection and the new film coefficients.
