    • In order to improve the energy balance for air cooling in equipment cabinets, in particular cabinet arrangements in computer centres and server rooms, regulation of the fans for the cooling air circuit is proposed, by means of which precisely the required amount of cooling air can be made available in the induction area to the electronic module units, in particular servers, in the equipment cabinets.According to the invention, at least one leakage air flow is formed between a cold air channel and an exhaust air channel, and is provided with a temperature sensor. The temperature measurement indirectly measures the flow direction and acts as a reference variable for regulating the rotation speed of the fans which, in particular, are arranged in the exhaust air channel. Regulation of the fan rotation speed matches the volume flow of the cooling air circuit to the volume flow actually required by the electronic module units, and therefore reduces the electricity consumption.
    • 为了提高设备机柜的空气冷却能量平衡,特别是计算机中心和服务器机房的机柜布置,提出了对冷却空气回路的风扇进行调节,借此可以精确地确定所需的冷却空气量 在感应区域中可用于设备机柜中的电子模块单元,特别是服务器。 根据本发明,在冷空气通道和排气通道之间形成至少一个泄漏空气流,并设置有温度传感器。 温度测量间接地测量流动方向,并且作为用于调节特别是布置在排气通道中的风扇的转速的参考变量。 风扇转速的调节将冷却空气回路的体积流量与电子模块单元实际需要的体积流量相匹配,因此降低了电力消耗。
