On the other hand, cryogenic compressed air in the heat exchanger temperature rise, so that the exhaust pipe is not caused by low temperature and dewing phenomenon.
另一方面，低温压缩空气在热交换器里温度得到回升，使排气管道外壁不致因温度过低而出现结露现象。
The ventilation system consists of a supply and exhaust air unit with a counterflow heat exchanger which provides 85% heat recovery.
通风通风系统包括一个送风单元，一个排风单元，与一个可回收85%热能的逆流式换热器。
Mainly used in thermal power, chemical industry, iron and steel and other enterprises of the heater, cold oil cooler, cooler, sampling cooler, exhaust gas cooler, heat exchanger, etc.
主要用于火力发电、化工、钢铁等企业的加热器，冷油器，冷水器，取样冷却器，抽气冷却器，换热器等。
According to the efficiency of heat exchanger, we can determine the suitable conditions of outdoor air for heat recovery from exhaust air by considering energy consumption of fan.
根据换热器的换热效率，考虑风机能耗，可以确定适合进行排风热回收的室外空气参数。
