为满足补风需要，设机械加压送风系统，送风量按不小于排烟量的50%计算。
To satisfy the demands for air supplement, mechanical pressurized air supply system is set. Air supply level is calculated by no less than 50% of smoke exhaust level.
针对工程实际情况，采用热空气幕对补风进行加热，既简化了系统又能节省能量。
According to the actual conditions of the project, the design simplifies the system and saves energy by adopting warm air curtains to heat makeup air.
利用热风系统作为中心区域补风，改善主生产区空气质量。
Using hot blast system to supply air to the center region, the air quality in the productive area has been improved.
