求翻译：且排风集中处理，通过一效率≮50%的全热交换器来预热新风。调试室、油墨模块电路、喷头组装区备品库、原材料库采用布袋风管送风,其余为铁皮风管送风方式.所有排放气体须经活性炭吸收装置处理达标后排放。新风引入口或排风排出口需设防虫网，新风引入口设过滤网。是什么意思？

And exhaust focus on an efficiency of ≮ 50% of total heat exchanger to preheat the fresh air. Debug room, ink module circuit, the nozzle assembly area spare the library, raw materials library using cloth bags air duct, and the remaining metal duct air supply all the exhaust gases shall be subject to

and exhaust through a focus on efficiency, 50% of the Area refers the heat exchanger to heat air. Debug room, printing inks, sprinkler module circuit assembly area, library, and raw materials in the library bag air tube and the remainder of the building has a metal air duct blowing way all emissions

Also the row of wind centralized processing, passes an efficiency ≮50% entire heat interchanger to come the preheating new atmosphere.The debugging room, the printing ink module electric circuit, the nozzle assembly area spare parts storehouse, raw material storehouse use the cloth sack air hose bla

Exhaust focused in and through efficiency ≮ 50% total heat exchanger to warm the fresh air. Debug room, spare ink nozzle assembly module circuit area libraries, library bag-duct air distribution of raw materials, the remainder being iron sheet wind tube air supply. all after the activated carbon abs
