The invention provides a multi-area variable-air-volume air conditioning system. The multi-area variable-air-volume air conditioning system comprises a plurality of independent mixing air boxes, air pipes, temperature sensors arranged on the mixing air boxes, fresh air valves and air return valves. A compartment is divided into several independent areas, each area is provided with an independent modularized mixing air bellow, fresh air is sucked in through a frequency conversion air feeder of each mixing air bellow, and after the fresh air is mixed with return air in the mixing air bellow, the fresh air is fed into the compartment area where the fresh air is located. Each mixing air box is provided with a fresh air valve and an air return valve, meanwhile, a temperature sensor is arranged, the temperature of mixed air can be monitored, the mixing proportion of fresh air and return air is controlled by adjusting the opening degree of the fresh air valves and the opening degree of the air return valves, and therefore the air supply temperature is controlled, and a target set value is achieved. By means of the arrangement, a traditional carriage integrated air conditioning mode is changed, and individual air conditioning of local areas of the carriage is achieved by dividing independent areas of the carriage.

    本发明提供的一种多区域变风量的空气调节系统,包括多个独立的混合风箱、风管、设置于各混合风箱上的温度传感器、新风阀以及回风阀。将车厢分为独立的几个区域,每个区域均具有独立的模块化混合风箱,新风通过各混合风箱的变频送风机吸入,在混合风箱内与回风混合后,送入其所处的车厢区域内。每个混合风箱设有新风阀与回风阀,同时布置有温度传感器,可以对混合风的温度进行监控,通过调节新风阀与回风阀开启的大小,进而控制新风与回风的混合比例,从而控制送风温度,进而达到目标设定值。通过上述设置,改变了传统的车厢一体化空气调节方式,通过将车厢独立区域划分,实现对车厢局部区域的个性化空气调节。
