Abstract
The indoor overall environmental comfort of part limited spaces is studied in this paper. The operative temperature, illumination, and noise intensity are used as objective parameters in order to evaluate the thermal, luminous, and acoustic environment. The thermal, luminous, and acoustic environment are investigated by using the subjective questionnaire in this experiment, and the function relation of the single physical parameter is established. Then, using the effective-function comprehensive evaluation carries on non-dimensional, weighting, and penalty substitution synthesis for the evaluation index of thermal, luminous, and acoustic environment, and establishes the evaluation model of the indoor overall environment. According to the experimental results and evaluation analysis, it is considered that the noise intensity and operative temperature have great influence on the indoor environment overall comfort and the illumination has less effect. Referring to the ISO7730 standard and combining it with the situation of our country, the indoor overall environment is divided into the zone of comfort. The predicted overall comfort vote (POCV), which is greater than or equal to −0.5 is the high comfort zone I. The area of −0.5 > POCV ≥ −1.0 is designated as low comfort zone II. It provides a certain basis for the evaluation of indoor overall environmental comfort.
Highlights
In recent years some progress has been made in the common indoor environmental comfort in China [1,2,3,4]
The results showed that thermal environment and air quality were the two crucial factors for the overall satisfactory level
Of the of the participants decreased with the increase of noise intensity, and the relationship (AECV) of the participants decreased with the increase of noise intensity, and the relationship participants decreased with the increase of noise and theof relationship between the both is between the the both is is monotonic monotonic change
Summary
In recent years some progress has been made in the common indoor environmental comfort in China [1,2,3,4]. With the science and technology growth, and the rising in rail mileage and air throughput [5,6], the times and frequency of habitat and construction activities have increased from common indoor environment to specific indoor environment. People are often in the indoor environment, such as train carriage and flight carbine, and these indoor environments have important influence on people’s comfort and health. Most of the flight carbine (train carriage) indoor environments are long and narrow. They are affected by many physical environment factors. It requires a comfortable thermal environment, and a bright luminous environment and a quiet acoustic environment. The attentions and researches on the overall comfort of the specific indoor environments are increasing
