Air change rate control of ventilated ceiling concerning heat load in commercial electrical kitchen.

Author(s) : AKIMOTO T., HORIKAWA S., UENO K.

Summary

A ventilated ceiling system is an energy-saving replacement ventilation system for maintaining comfortable working environment in kitchens. The technology was introduced from Germany, but there have been no clearly determined relationships between their designs in an electric kitchen and the ventilation design standards and no established design methods. This study aims to establish design methods of ventilated ceiling systems appropriate for electric kitchens by assessing the thermal environment created and energy consumed by the systems while changing the amount of ventilation and the temperature of the air supplied. The ventilated ceiling system formed thermal stratification, which improved displacement ventilation, and maintained a good thermal environment in the working area. To meet the standards of the Ministry of Health, Labour and Welfare, the system should be operated at a ventilation rate of 25 times per hour with supply air at 16°C or a ventilation rate of 20 to 40 times per hour with supply air at or below 20°C.
