关于天津某高校夏季中央空调人体热舒适度的研究

Study on thermal comfort of central air-conditioning system in a Tianjin’s university in summer

高校是教学和科研的重要场所,热舒适度的高低会直接影响到工作和学习的状态及效率。通过对天津地区某高校GHP燃气空调的热舒适度进行分析,当空调设定温度为26℃时,利用PMV热舒适度计算方法计算出不同房间的热舒适度值都处于较舒适区域。另外,运用调查问卷的方式对高校师生进行了实际热舒适度的调查与分析,调查问卷结果与理论计算结果一致。结合理论计算结果与调查问卷结果,对不同的房间进行了个性化温度设置,通过对比运行数据,发现恰当的设置空调温度在提高师生热舒适度的同时还能节约能源。

Colleges and universities are important places for teaching and scientific research. The level of thermal comfort will directly affect the state and efficiency of work and learning. This paper analyzes the thermal comfort of the GHP gas air conditioner in a university in Tianjin. When the temperature of the air conditioner is set at 26 ℃,the thermal comfort value of different rooms is calculated by means of PMV thermal comfort calculation method. In addition,this paper also uses the questionnaire to investigate and analyze the actual thermal comfort of college teachers and students. The results of the questionnaire are consistent with the theoretical calculation results. Combining the results of theoretical calculation and questionnaire,the individual temperature setting was carried out in different rooms. Through comparing the running data,it was found that the proper setting of air conditioning temperature can also save energy while improving the thermal comfort of teachers and students.
