摘　　要：全空气空调系统中一次回风系统与二次回风系统是两种常见的处理方式,这两种方式各有优缺点,且它们的控制方式也不尽相同。介绍了一种新型的空调机组配置及控制思路,提出了风阀、冷水阀、热水阀“三阀联控”的概念。即在同一个空调系统中把一次回风与二次回风结合在一起,在增加极少初投资的情况下,实现室内温湿度的控制,最大程度地避免冷热抵消,满足节能的需求。Primary air return system and secondary air return system are two common treatment methods in all air air conditioning system.These two methods have their own advantages and disadvantages,and their control methods are not the same.In this paper,the configuration and control idea of a new type of air handling unit were introduced,and the concept of"three valve combined control"of air valve,cold water valve and hot water valve was put forward.That is,in the same air conditioning system,the primary return air and secondary return air were combined together to realize the control of indoor temperature and humidity under the condition of little increase in initial investment,to avoid cold and heat offset to the greatest extent and meet the demand of energy saving.
