The invention relates to the technical field of vehicles, and provides a working cabin, a control method and a fire engineering vehicle. The working cabin comprises a cabin body which is internally provided with at least two cabins; the fan is connected with the cabin and used for supplying air to the cabin; the filtering device is connected with the fan and is used for filtering air; the pressure adjusting assembly is connected with the cabin body and used for controlling the pressure value in each cabin; when the pressure adjusting assembly is in the first working mode, all the cabins are in a positive pressure state, and the pressure of each cabin is decreased progressively, and when the pressure adjusting assembly is in the second working mode, part of the cabins are in the positive pressure state, and the pressure of each cabin is decreased progressively when the number of the cabins in the positive pressure state is larger than one. Due to the fact that the pressure gradient exists between the cabins, air mixed with pollutants in the downstream cabin cannot flow reversely to enter the upstream cabin, and the defect that in the prior art, pollutants in a cleaning room easily enter a laboratory in the process that operators return to the cabins is overcome.
本发明涉及车辆技术领域,提供一种工作舱、控制方法及消防工程车辆。工作舱包括:舱体,内部设有至少两个舱室;风机,与舱室连接,用于向舱室送风;过滤装置,与风机连接,用于过滤空气;压力调节组件,与舱体连接,用于控制每个舱室内的压力值;压力调节组件处于第一工作模式时,所有舱室处于正压状态,且每个舱室的压力递减,压力调节组件处于第二工作模式时,部分舱室处于正压状态,且处于正压状态的舱室的数量大于一个时,每个舱室的压力递减。由于舱室之间具有压力梯度,使得下游的舱室内的混杂有污染物的空气不能逆向流动进入到上游的舱室内,解决了现有技术中作业人员返舱过程中清洁室内的污染物容易进入到实验室内的缺陷。
