Abstract
Taking a four-person dormitory e-quipped with air conditioner and door air curtain in a university in Wuhan as the research object,the temper-ature field and speed field of the height plane(1.1 m)where the head is located when the person is sitting are simulated under different outdoor temperature condi-tions during the heating period.Taking the overall lev-el of air temperature and the uniformity of air tempera-ture distribution at a height of 1.1 m as the evaluation criteria,the appropriate air supply angle of the air con-ditioner is selected.Taking the low temperature(below 23 ℃)area ratio of 5% at the height of 1.1 m as the evaluation criterion,the optimal air supply speed of the air curtain under different outdoor temperature condi-tions is determined.The air supply angle of the air conditioner should be 45°.When the low temperature area ratio at the height of 1.1 m is 5%,the optimal air supply air speeds corresponding to the outdoor tempera-tures of 8,3 and-2 ℃ are 0.18,0.30 and 0.46 m/s,respectively.The air speed distribution at the height of 1.1 m is dominated by the air supply from the air conditioner,and the high-speed area appears in the middle of the two lockers.The air curtain air supply speed basically has no effect on the air speed distribu-tion at the height of 1.1 m.关键词
