绪论
思考题
1.人类对空气调节工程提出了哪些要求?
空气调节系统是如何满足这些要求的?
答:
对空气温度、湿度、空气流速和清洁度进行调节,使空气达到所要求的状态。
另外,就目前社会发展来看,人类对空调工程的要求远不止这些,其中对节能、环保以及对社会安全性的保障也提出了更高的要求。
空调系统采用换气的方法,保证所要求环境的空气新鲜,通过热湿交换来保证环境的温湿度,采用净化的方法来保证空气的清洁度。
不仅如此,还必须有效的进行能量的节约和回收,改进能量转换和传递设备的性能,优化计算机控制技术等来达到节能的目的以满足人类要求。
2.空气调节与全面通风有哪些相同和不同之处?
空气调节由哪些环节组成?
答:
全面通风往往达不到人们所要求的空气状态及精度。
空气调节是调节空气的状态来满足人类的需求。
两者同样是改变了人体所处环境的空气状态,但是空气调节包括了通风、供暖和制冷等过程。
空气调节包括:
空气处理、空气运输、空气末端分配以及气流组织。
3.空气调节技术目前的发展方向是什么?
答:
节能、环保、生活安全性。
空调新技术的发展:
如空调系统的评价模拟、温湿度分别处理、计算机网络控制技术等。
