    Recently, it is on the increase that centers of providing school lunch are installed electrical kitchens. In these cases, some centers adopted the ceiling ventilation system that no hood is required in each cooking machine. The application of this new ventilation system is expected to reduce the energy consumption of electrical kitchens. However, a systematic planning technique has not been established. Therefore, on the planning of the ventilation and air conditioning systems in centers installed electrical kitchens, it is necessary to grasp the present conditions of these centers. In this report, according to the brochures of the centers and the results of the questionnaire survey, the actual condition is investigated and analyzed. The contents of the condition are the scale and dimension of the centers, settings and capacities of cooking machines, types and air volume of ventilation, indoor design temperature and humidity of air conditioning system, total energy consumption, and so on.

    It has been reported that the energy consumed in heat transporting equipments of air conditioning system accounts for about the half of that consumed in a whole air conditioning system of a commercial building. Recently, the heat transporting system with large temperature difference of heating medium has been the main one to decrease the power consumption of heat transportation. In order to decrease power consumption of the cool water transporting system more, the possibility of ice-water transporting system has been under examination and the IPF measuring method with low cost and high accuracy is in need. In this study, the electric resistance method was adopted to measure the IPF of slush ice-water flow in a tube. The model, which is that the single isolator arranged in the center of electrodes, was proposed and the electric resistance between electrodes in a tube wall was considered to be a compound of that of the proposed model. The relation ship between the measured electric resistance and the volume ratio of insulator was experimentally obtained. The experimental equation was obtained based on the form of quasi-theoretical equation. The shape of electrodes, the applying voltage conditions and the practical measuring electric circuit were proposed and the simple and convenient IPF measuring system was constructed. Then it was found that the accuracy of proposed IPF measuring system was almost the same as that of weight method.

  • Reduction of Oscillation Noise Generated in a Premixed-Combustion Type Boiler by Using a Cylindrical Muffler with Sliding Stopper

    A premixed-combustion type boiler with a multi-port burner plate has a strong tendency of extremely loud noise in the frequency range determined by the geometric structure of boiler system. Therefore, it is necessary to propose a noise reduction method for this type of boiler. In this paper, the passive reduction method using a cylindrical muffler with sliding stopper is proposed, considering the fact that the frequency spectrum of combustion driven oscillation noise has a peak level, that is similar to acoustic resonance of pipe. In this paper, at first, basic features of oscillation noise are made clear, and then noise reduction effect of proposed muffler, and its features and optimal parameters for its use are experimentally examined. Experimental results show that using the proposed muffler has a striking effect on noise reduction and the sound level can be lowered to the ground noise level by about 40dB at most.

    Currently indoor environment studies focus on phenomena around the human body at the microclimate level, and therefore the need for more realistic and detailed human body models has been pointed out. Numerical models representing closely the actual shape of the human body have already been proposed for seated female models (or androgynous models based on female body shapes), and are available for indoor environment analysis applications. However, other human body shapes have not been modeled. In addition, since existing models use coarse meshes, sufficient detailed data on various parts of the human body has not been gathered. This study aims to develop virtual manikins that represent human body scales for adult males and females as well as child (almost seven-year-olds). The virtual manikins developed in this study cover two types of posture models. The virtual manikin is divided into 17 parts for the control of the thermal manikin, allowing the control and analysis of radiation heat transfer, surface temperature, and other factors in each part. We examined the accuracy of indoor environment prediction by conducting a coupled convection and radiation analysis on a simple room. As a result, we confirmed that thermal environment prediction could be carried out with sufficient accuracy in the analysis of microclimates around the human body.

    A daily water demand predicted by time-varying inhabitants' behavior schedules that are generated through the authors' method is compared with a real observed one for Kugahara, Ota Ward, Tokyo, the Metropolitan government measured. The prediction requires not only the schedule data but also assuming both a unit water consumption rate for each inhabitant's behavior and the family type distribution of Kugahara Area. It has been proved that the predicted daily water demand agrees with the real observed data.
