Laboratory multi-section ventilation energy-saving control system

Abstract

The invention discloses a laboratory multi-section ventilation energy-saving control system, and relates to the technical field of laboratory ventilation equipment. The laboratory multi-section ventilation energy-saving control system comprises a frequency conversion draught fan, a centralizing box and a plurality of ventilation cabinets connected with the centralizing box. Air valves are arrangedon ventilation branches from the centralizing box to the ventilation cabinets. The ventilation cabinets are connected with a face air speed monitoring and control system. The face air speed monitoring and control system comprises face air speed sensors arranged in the ventilation cabinets and a variable air volume controller. The variable air volume controller is connected with the frequency conversion draught fan and measures the aperture of the ventilation cabinets in real time. Meanwhile, the face air speed sensors measure the face air speed in real time and convert the face air speed intovoltage signals transmitted to the variable air volume controller. The variable air volume controller compares the face air speed actual value and the set value, if the face air speed is not in the set value range, the variable air volume controller outputs control signals to the frequency conversion draught fan, and the frequency conversion draught fan receives the control signals and adjusts the ventilation air volume. The laboratory multi-section ventilation energy-saving control system capable of conducting intelligent frequency conversion according to the actual air utilization volume and achieving energy saving is provided.

Description

technical field [0001] The invention relates to the technical field of laboratory ventilation equipment, in particular to a laboratory multi-stage ventilation energy-saving control system. Background technique [0002] The ventilation of the laboratory plays a vital role in the environmental quality of the laboratory and the health of laboratory operators. In order to prevent the pollutants produced in the experiment from spreading into the laboratory, all kinds of laboratories are equipped with ventilation systems, but The existing ventilation system either does not have the function of air volume control. As long as one fume hood in the system is turned on and used, the exhaust motor will run at full capacity, which is not conducive to energy saving. Contents of the invention [0003] This application provides a multi-stage ventilation energy-saving control system for laboratories that realizes energy saving by intelligent frequency conversion air supply according to the...
