The thermal comfort provides satisfaction of thermal environment and affects productivity of occupants in residential building. So, it is time to foster a comfortable indoor environment, while minimizing the energy consumption of building systems. However, Indoor thermal environment is controlled by temperature with wall mounted thermostat in usual. Indoor temperature control could not be provided the thermal comfort at all the time because thermal comfort is influenced by many parameters of environment such as temperature, relative humidity, air velocity, activity level, clothing insulation and radiant temperature. The purpose of this study is that predicted mean vote (PMV) would be available as index as control parameter. Energy consumption and Thermal comfort are evaluated both PMV control and temperature control by simulation and several cases were compared, in which the set-point temperature range of between 22oC and 24oC and, set-point PMV index through the respective heating season in the simulation. As a result, PMV control is better to maintain human comfort condition and to save the energy than ordinary set-point temperature. |
