But Controled cooling USES temperature control, time control on the whole line and speed of rolling.
而控制冷却可采用全线的温度控制、时间控制、轧制速度来实现。
The speed of the compressor is varied to control the refrigerant flow rate and match the cooling load requirements of the vapor compression system.
该压缩机的速度被改变以控制该制冷剂的流速和配合蒸气压缩系统的冷却负荷需求。
And using the frequency variable adjusting speed technique to control the speed of benzole cooling pump automatically, to achieve the temperature stability of the benzole.
同时利用变频调速自动控制粗苯冷却泵的转速，实现粗苯温度的稳定。
