Analysis of Heating Methods for High and Large Building Spaces

Based on the theoryof heattransfer, the virtues and shortcomings of different heatingmethods for high and large building spaces are analyzed. The numerical and experimental results of the laminar heating by horizontal hot air curtains are presented in detail. The results showthatmore comfortable but less energy consumption can be obtained with the laminar heating by horizontal hot air curtains than the conventional radiation heating in high and large building spaces.
