여름철 실내 수면 시 벽걸이 에어컨의 취출각도에 따른 온열환경 분석

Abstract

In summer, main cause which feel displeasure is Temperature and humidity. Human is influenced by solar radiation at daytime and is influenced by the tropical night phenomenon which keep up 26℃hrough the night. For the minimum displeasure, we use the air conditioner which control temperature and humidity. Generally, air conditioner divides stand air conditioner and wall hanging air conditioner. Among them, wall hanging air conditioner operates in room such as bedroom. It operates both daytime and night time including sleep. But supply angle of air-conditioner didn’t consider at sleep time. Thereby supply air of air-conditioner has considerable a impact on human who is sleeping. If human exposes cooling airflow, human may have headache, suffocation and body heat lowering because of rapid heat exchange between skin and environment. Therefore this research analyzes thermal environment by supply angle of wall hanging air conditioner at sleeping in summer. Above all we compare experiment data with simulation data at supply angle 60°for the accurate simulation data. Then simulation data Supply angleof wall hanging air conditioner divide five CASE(15°, 30°, 45°, 60°, 75°). The analysis factors are airflow, temperature, PMV (Predicted Mean Vote). Through the analysis, this research finds optimal supply angle at sleeping.
