| Popis: | 92 The development of computer technology and Internet lead to the changing of traditional production method and technology, both of which resulted in changes in the office work process and production ability. The work environment also gradually moved from tightly packed outdoor manpower to mostly indoor computer operation; even some leisure activities moved from outdoors to inside. To ensure that indoor activities be conducted in a healthy and comfortable environment, air conditioning is an indispensable component. The issue of achieving a comfortable and energy efficient air conditioning design and management in an airtight space is an important research topic. The investigation of thermal comfort is based on two main standards, which are ISO 7730 and ASHRAE55. However, the comfort indexes PMV and PPD in these two standards came from foreign studies, thus their applicability in Taiwan temperate requires further investigation. The study applied surveying questionnaire and environmental measures to establish the thermal comfort index for the lecture theater in the NATIONAL MUSEUM OF NATURAL SCIENCE, and compared with comfort values among residents of foreign, and Southeast Asia. This investigation observed the reactions of 251 people in the lecture theater of the museum, stratified by sex, age, figure, and amount of clothing and activity. We used a instrument to monitor parameters such as temperature, relative humidity, Co2, and velocity at six fixed locations throughout the day. The results of this investigation showed that the comfortable temperature accepted by the study subjects is 25oCta in the summer and 21.4oCta in the winter. There was little difference in the accepted comfortable temperature of different sex and age groups during the summer, while women and people over forty years of age prefer higher temperatures and fatter people prefer lower temperatures in the winter. Indoor relative humidity also has little influence on the comfortable temperature. |
