| Outline of Final Research Achievements |
The human sensation and the energy performance using the various air-conditioning system (convective (CAC) and radiative (RAC)) is considered by measurement of the real housing and the numerical simulation. As the main results, the non-uniform radiative environment during the floor heating system was accurately calculated and the human sensation was improved by thermal conduction and the radiant from the hot floor to a body part, and RAC is possible to achieve the energy saving. Then the other housing which uses the vertical-type radiation panel system clarified, if the radiative area is enough, the air-conditioning system is possible even with a low-quality heat source, and the high insulation performance housing improves RAC efficiency. Furthermore, in order to consider the influence of CAC (air-conditioner airflow), a simple model that can easily predict the influence of the air-conditioner airflow was formulated by analyzing the temperature distribution using the CFD.
