Abstract

Indoor airflow distribution plays a very important role in the health of personnel and environmental quality, and floor air supply, as a new form of air supply, is widely concerned because of its characteristics of improving air quality in the work area, energy saving and environmental protection, etc. In this paper, a vertical temperature measurement device was established in the floor air supply laboratory, and the distribution of measurement points was selected from 0.1 m, 0.3 m, 0.6 m, 0.9 m, 1.1 m, 1.3 m, 1.7 m, and By comparing the overall indoor temperature size, indoor vertical temperature gradient, thermal stratification height, air supply temperature, indoor thermal load, air supply volume, we obtain the characteristics of the influence of air supply parameters and environmental parameters on the indoor vertical temperature distribution of the downdraft and downdraft ventilation system.
