1、风机盘管的回水管上应设置浮点式电热阀,也可采用传统的电动两通阀或电动两通调节阀。前者与后两者相比,具有控制精度高、运行稳定性强、无噪声、体积小等优点;新风机组、组合式空调器的回水管上,应设置动态平衡电动调节阀或电动两通调节阀。前者只受房间温度设定控制,不受外网压力波动的影响,比后者具有更好的调节特性和更长的使用寿命。
1. The floating-point type electric heating valve should be set on the backwater pipe of the fan coil, and the traditional electric two - way valve or the electric two - way regulating valve can be used. Compared with the latter two, the former has the advantages of high control accuracy, strong operation stability, no noise and small volume. The dynamic balancing electric control valve or electric two way regulating valve should be set up on the return pipe of the new air unit and the combined air conditioner. The former is only controlled by the temperature setting of the room, which is not affected by the pressure fluctuation of the external network, and has better regulation characteristics and longer service life than the latter.
2、总供回水管之间设旁通管及由压差控制的旁通电动调节阀,旁通管管径应按1台冷水机组的冷冻水流量确定。
2. There is a bypass pipe and a bypass electric regulating valve controlled by pressure difference. The bypass pipe diameter should be determined according to the freezing water flow rate of 1 chillers.
3、冷水机组和冷冻水循环泵之间宜采用一一对应的连接方式。当采用方式连接困难时,可采用共用集管连接,但此时应在每台冷水机组的入口或出口水管道上设置电动隔断阀,并应与对应的冷水机组和水泵连锁开关。
3. A one-to-one corresponding connection should be adopted between the cold water set and the frozen water circulating pump. When the way connection is difficult, the common collector pipe connection can be used, but at this time, the electric partition valve should be installed on the inlet or outlet piping of each chiller, and should be connected with the corresponding chiller and water pump interlocking switch.
4、应密切与电器专业配合,做好自动控制设计,使系统能够根据空调负荷的变化,自动控制冷水机组及循环水泵的运行台数。
4, we should closely cooperate with electrical equipment and do automatic control design, so that the system can automatically control the running number of chillers and circulating pumps according to the change of air conditioning load.
