介绍了主动式冷梁和被动式冷梁的原理与特点,分析了冷梁系统的气流组织形式与适用性,并将其与普通的风机盘管系统进行了对比。认为冷梁作为干工况风机盘管的一种先进的应用形式,是现有系统很好的补充,非常适用于办公室等区域。指出目前普遍采用的系统设计形式并不能发挥冷梁的节能优势,提出了采用冷梁和空调箱分设冷水机组的节能设计方法。同时指出冷梁有一定的适用范围和限制因素,应用时必须结合建筑实际进行选择。
The principle and characteristics of active cold beam and passive cold beam were introduced. The airflow organization and applicability of cold beam system were analyzed and compared with the conventional fan coil system. It is considered that cold beam, as an advanced application form of fan coil in dry working condition, is a good complement to existing systems and is very suitable for offices and other areas. It is pointed out that the current system design form does not give full play to the energy saving advantages of chilled beams. The energy - saving design method using chilled beams and air - conditioners as separate chillers is proposed. At the same time, it is pointed out that the cold beam has a certain scope of application and limitation factors, and the application must be combined with the actual construction choice.
