Effects on the Indoor Thermal Environment and Energy Consumption Based on Installing the Ventilation Control System in an All Electric Center of Providing School Lunch

Abstract

Ventilation control system was developed and installed in an all electric center of providing school lunch. The system is able to control ventilation rate according to the change of indoor absolute humidity affected by uses of cooking appliances. The purpose of this study is to clarify the effects on the indoor thermal environment and electric energy consumption for ventilation and air conditioning by the installation of ventilation control system. From the measurements under the condition of the practical uses in the cooking room, the indoor thermal environment after the installation could be as good as it before installation. The electric energy consumption for ventilation and air conditioning was reduced by the developed ventilation control system.
