Air supply system and control method thereof

The invention relates to the technical field of tobacco production environment humidity control, in particular to an air supply system and a control method thereof. The air supply system comprises a fresh air system and a high-pressure micro-mist humidifier, wherein the fresh air system comprises a fresh air inlet, a surface air cooler and a fresh air outlet, the surface air cooler is arranged between the fresh air inlet and the fresh air outlet and used for dehumidifying airflow flowing from the fresh air inlet to the fresh air outlet, the high-pressure micro-mist humidifier is arranged on the upstream of the fresh air inlet and used for humidifying airflow flowing to the fresh air inlet from the outdoor environment. Therefore, the influence of the outdoor environment on the indoor humidity can be reduced, and the stability of the indoor humidity is improved. 本公开涉及烟草生产环境湿度控制技术领域，特别涉及一种送风系统及其控制方法。送风系统包括：新风系统，包括新风入口、表冷器和新风出口，表冷器设置于新风入口和新风出口之间，用于对由新风入口流向新风出口的气流进行除湿；和高压微雾加湿器，设置于新风入口的上游，用于对由室外环境流向新风入口的气流进行加湿。基于此，
