Variable air volume zone control fan wall and control method for ventilation and air conditioning system of subway station

Abstract

The invention relates to a variable air volume partition control fan wall for a ventilation and air conditioning system in a subway station and a control method, including a plurality of fans embedded in the wall, the plurality of fans are supported and arranged by a fan wall frame and a base, and are arranged according to the subway station The air volume required for the operation of different refrigeration systems of the ventilation and air-conditioning system is divided into areas for multiple fans, and each area is provided with an air-tight valve, which is opened and closed in synchronization with the fans in the corresponding area. The variable air volume partition control fan wall is arranged in the air duct according to the layout of the subway station's civil construction tunnel, and the layout is reasonable, compact in design, stable and reliable; through partition control, the air volume is effectively controlled to meet the needs of different working conditions, the control method is unique, and the operation is energy-saving and efficient.

Description

technical field [0001] The invention relates to a ventilation and purification air-conditioning system for a subway station and an underground space, in particular to a fan wall and a control method for the ventilation and air-conditioning system of a subway station with variable air volume partition control. Background technique [0002] The ventilation and air conditioning of traditional subway stations adopts the "water-cooled chiller + cooling tower + combined air conditioning unit" system, using traditional centrifugal fans or tunnel fans to be installed in machine rooms or new and exhaust civil tunnels to achieve the purpose of air conditioning, ventilation or smoke exhaust . The traditional subway station ventilation and air conditioning system refers to the ordinary air conditioning system. A variable air volume control device is installed in the air duct, and then the air valve is manually controlled to control the speed of the fan in the air duct, thereby controlli...
