基于冷镜式光电露点仪的实验教学设计

Experimental teaching design based on a chilled mirror type photoelectric dew-point meter

针对建环专业本科生对于空气状态参数的测试原理及耦合关系缺乏了解等问题,以教学型冷镜式光电露点仪为实验平台,开发了空气状态参数测定和简单空气处理过程实验,通过测量空气干球温度和露点温度,计算其他状态参数,并展示了实践教学应用案例。该实验适用于建筑环境与能源应用工程及相关专业实践教学,为学生提供了良好的实验平台,让学生深入了解空气状态参数的本质概念及测定原理。

Aiming at the problem that the HVAC undergraduate students are difficult to understand the test principle of air state parameters and their coupling relationship,a teaching chilled mirror type photoelectric dew-point meter was used as an experimental platform,and an experiment of air state parameters determination and simple air conditioning process was developed.By measuring air dry bulb temperature and dew point temperature,other state parameter can be calculated.A practical teaching application case was showed,which was applicable to HVAC experimental teaching.A good training platform was provided for HVAC teaching,which can lead the students to understand the nature of the air state parameters and the measurement principle,and the teaching quality and students＇ learning interest are improved.
