The experimental results on the cooling load of a large factory space using a three dimentional 1/10 scaled down model are described. Comparison was made on the vertical temperature distribution and cooling load among the cases of overall air-conditioning, occuoied zone air-conditioning and spot air-conditioning. From the measuredresults of vertical temperature distribution it was found that occupied zone air-conditioning cooled the space of 3m or more above the floor level when internal heat generation was increased and that spot air-conditioning did not cool it even if internal heat generation became greater. When internal heat generation was 26.7W/m^2, 133W/m^2 of floor area, the percentage of cooling load curtailment of occuoied zone air-conditioning to overall air-conditioning were 32%, 19%, and 8% respectively and that of spot air-conditioning 74%, and 78%, and 81% respectively. It was found that the energy-saving effect by occupied zone air-conditioning decreases as internal heat generation was large and that the energy-saving by spot air-conditioning became large even when internal heat generation increased.
