Abstract

Based on an engineering training centre, a scaled model laboratory with a geometric ratio of 1:4 was established. The indoor thermal environment and stratified air-conditioning load (SACL) of the scaled model laboratory with low-sidewall air supply was experimentally studied. The heat gain through the building envelope was simulated in the form of step thermal disturbance by the electric heating film attached to the walls and roof. The lab was commissioned by a series of pre-experiments, and seven experimental cases were conducted with different exhaust ratios and indoor heat source heights. The experimental results indicated that when the exhaust ratio was increased from 0 to 21.63%, the internal wall surface temperature was reduced by 2.85 °C, the indoor air temperature in the air-conditioned area was reduced by 0.84 °C and the SACL was reduced by 18.90%.
