Abstract

The invention provides a VAV control system. A communication module and an information processing module are connected with each other. The communication module and a client controller are connected through wireless communication. A timing module and the information processing module are connected with each other. A touch control module is connected with the timing module and the information processing module. The timing module and the information processing module are controlled by the touch control module. A detection module is connected with the information processing module. The VAV control system is further provided with an alarm module with an alarm function, a power supply device used for supplying power to the information processing module, and an execution module used for receiving an instruction issued by the information processing module and executing an action. The information processing module controls the work of the alarm module and the execution module. The control module of the system is connected with the communication module and the client control terminal, and has a remote operation function. The alarm module can give an alarm to inform the staff to carry out maintenance or debugging. The VAV control system is very practical.

Description

technical field [0001] The invention belongs to the technical field of variable air volume control systems, and relates to a VAV control system. Background technique [0002] As long as the VAV controller is used in laboratory fume hoods, fume hoods, detoxification cabinets, laboratory ventilation systems, air conditioning exhaust systems, etc., it is used to adjust the ventilation volume and other functions. [0003] For example, a controller based on VAV air-conditioning fresh air optimal distribution published by Chinese patent application number is 200810036543.3. In the present invention, the data collected by the input module is sent to the storage module, and the storage module stores the required data. The fresh air volume calculation and control module calculates the total fresh air demand of the system and the fresh air demand ratio of each area, and finds the largest fresh air demand among them. Ratio, take this value as the fresh air ratio setting value of the s...
