中央空调动力节能降耗的特点介绍

(1)采用大温差如果系统中输送冷热能用的水(或空气)的供回水(或送回风)温差采用较大值,那么当它与原有温差的比值为m,从流量计算公式知道,采用大温差时的流量降为原来流量的1/m3。
(1) the large temperature difference if the system can be used in conveying hot and cold water (or air) of supply and return water (or return air temperature) with larger values, so when the ratio of it and the original temperature is m, from the flow equation with large temperature difference that flow down to the original traffic 1/m3.
这时,水泵或风机要求的功率将减小到原来的1/m3。可见,加大温差对中央空调节能降耗的效果是明显的。在满足中央空调精度、人员舒适和工艺要求的前提下,应尽可能加大送风温差。要注意的是:供、回水的温度差不宜大于8摄氏度。At this time, the power required by the pump or fan will be reduced to the original 1/m3. It can be seen that the effect of increasing temperature difference on energy saving and consumption reduction of central air conditioning is obvious. In order to meet the central air conditioning accuracy, personnel comfort and process requirements, should be possible to increase the temperature of the air supply. It should be noted that: the temperature difference between supply and return should not be greater than 8 degrees celsius.
(2)选用低流速因为水泵和风机要求的功耗大致与管路系统中的流速成正比关系,因此,要取得中央空调节能降耗的运行效果,在设计和运行时不要采用高流速。此外,干管中采用低流速还有利于系统的水力工况稳定性。
(2) the use of low velocity because the power requirements of the pump and fan are directly proportional to the flow rate in the pipeline system and, therefore, to achieve the effect of energy saving operation of central air-conditioning, do not use in the design and operation of high velocity. In addition, the use of low flow rate in the dry pipe is also conducive to the stability of the hydraulic system.
