变风量系统的节能特性为暖通空调界所熟知。在新建的工程和改建的工程中广泛采用了变风量系统。有的设计师开始把变流量的原理用于冷冻水系统中。一些颇为重要的特性为节能和系统的简化提供了可能性。通过许多工程还发现了另一个优点,即克服了某些常见的冷冻水系统中的缺点和运行中存在的问题。一、高峰负荷与建筑物总负荷的比较 The energy-saving features of VAV systems are well known in the HVAC industry. VAV systems are widely used in new construction and remodeling projects. Some designers began to use variable flow principles in chilled water systems. Some of the more important features provide possibilities for energy savings and system simplification. Another advantage discovered through many projects is that it overcomes the shortcomings in some common chilled water systems and problems in operation. A.
