신조 운항실습선의 여름철 실내 온열환경 실측평가

Abstract

The purpose of this study is to measure and analyze the ship's indoor thermal conditions and also to integrate experimental database of those which are supplied and controlled by marine HVAC. On this study, temperature, humidity and air volume of 6 different needs' cabin are measured like previous report on a newly-launched training ship during 25th through 27th of July, 2007. Followings are the results of this study. (1)The air supply volumes to each cabins are measured 250CMH(Recreation room), 800CMH(Conference room), 1,000CMH(Bridge), 5,100CMH(Lecture room) respectively. (2)The temperatures are maintained at 21~27℃ in almost cabins through measuring period, but the temperatures are fluctuated over ±4℃ at the bridge and conference room. (3)The relative humidities are shown between 40~60% known as comfort conditions, but the conference room is needed to dehumidified because of over 70% humidity. (4)From the student cabins' measurements which have different supply diffuser(s), it is clear that the design is suitable for this case. (5)Because of temperature diversities, only 32% among the measured data are satisfied with the comfort standard range proposed by ASHREA.
