空调雾化器该雾化节能装置是利用冷凝水或经过水处理后的外接水将其雾化，并将水雾喷洒到空调器或冷库冷凝器表面，使空调器或冷库单一的风冷变成风冷和雾化水冷却的混合式冷却，从而大大降低冷凝器的冷凝温度和冷凝压力，减少压缩机的高低压差，降低了压缩机由于高温保护造成跳机频繁或启动困难的现象，不仅增加了压缩机使用寿命，而且对空调器有显著的节能效果——制冷量增加，输入功率减少。

In order to meet the need of economic development for large-specification roll of steel plates, technical improvements have been carried out in the hot-rolling mill.
