根据中央空调系统冷水/冷却水/冷却塔系统的系统性节能分析，在冷却水系统和冷冻水系统采用一体化变频调速控制柜，其中冷却变频调速控制柜负责冷却水泵切换（循环）使用，冷冻变频调速控制柜供冷冻水泵切换（循环）使用，冷却塔采用无电机风机做动力。变频节能调速系统是在保留原工频系统的基础上加装改装的，变频节能系统的联动控制功能与原工频系统的联动控制功能相同，变频节能系统与原工频系统之间设置了联锁保护，以确保系统工作安全。利用变频器、人机界面、PLC、数模转换模块、温度传感器、温度模块等器件的有机结合，构成温差闭环自动控制系统，自动调节水泵的输出流量，为了达到节能目的提供了可靠的技术条件。

对于利用变频器、人机界面、PLC、数模转换模块、温度模块、温度传感器等构成的温差闭环自动调速系统。在空调机组故障快速切换并报警，减少人员值班巡查次数。对冷冻泵、冷却泵、冷却塔无电机购房进行改造，以节约电能、稳定系统、远程监控同时均衡各设备时间延长设备寿命。

 应用ANH-L中央空调系统，目的是提高产品质量，提高人的舒适度，集中供冷供热效率高，便管理，节省投资等原因，对于企业、高层商厦、商务大楼、会场、剧场、办公室、图书馆、宾馆、商场、超市、酒店、娱乐场、体育馆等中大型建筑上都是应用中央空调综合体，它是现代大型建筑物不可缺少的配套设施之一，电能的消耗非常之大，是耗电大户，几乎占了用电量50~80%，对于整个运营及企业利润造成深远影响。

Freezing means lowering the temperature and allowing the object to solidify and freeze. Also called "refrigeration", it is the application of thermodynamics principle, the method of artificially manufacturing low temperature, refrigerator and air conditioner are all based on the principle of refrigeration. From the chemical point of view, it is generally used a gas with a high critical point, pressurized and liquefied, and then it is vaporized and absorbed, and this process is repeated. When liquefying, it is exothermic in other places, and when it is vaporized, it absorbs heat to the required range. . Central air conditioning, screw chiller, air-cooled module heat pump air conditioner, brine cryogenic machine, heat pump hot water project, constant temperature and humidity air conditioning, precision air conditioning, quick freezing, freezing, cold storage, clean technology and purification system engineering design and installation business. Have professional HVAC maintenance and repair: lithium bromide unit, centrifugal compressor, screw compressor, scroll compressor, piston compressor, maintenance and repair.
