制冷机通过压缩机将制冷剂压缩成液态后送蒸发器中与冷冻水进行热交换，将冷冻水制冷，冷冻水泵将冷冻水送到各风机风口的冷却盘管中，由风机吹送冷风达到降温的目的。经蒸发后的制冷剂在冷凝器中释放出热量，与冷却循环水进行热交换，由冷却水泵将带来热量的冷却水带到散热水塔上由水塔风扇对其进行喷淋冷却，与大气之间进行热交换，将热量散发到大气中去。 
旧操作系统为“星-三角转换起动”全压运行，此时空调机组在满负荷状态下工作，系统在起动电机时不能平滑起动，起动时对电网冲击大，长时间频繁起动将造成电机的绝缘性下降，电机温升过高，在运行过程中不能有效的根据病房与办公楼的需求，对温度进行有效的调节，只能工频最大量进给，这将势必造成能量的浪费。
而通过变频频改造后，能根据房间的制冷及制热的需求自动调节冷冻泵及冷却泵的流量而达到节能降耗的目地。
（1）由于目前冷却水循环泵为工频满负荷运转，在制冷周期的前期和后期，环境温度较低，冷却水回水温度较低，会造成溴化锂结晶，导致空调机组效率降低，甚至保护。采用变频恒温差控制后，回水温度得到有效控制，将大大提高空调机组的效率，达到节能目地
（2）由于冷冻水循环泵也在工频满负荷运转，而不能根据室内温度的要求自动调节流量，而通过变频改造后冷冻泵能根据室外温度及室内温度要求能自动调节流量，提高效率，达到节能目地。
（3）减小空调开机、停机时对供电和系统的冲击
减小空调开/停机对电网的冲击，由于循环水泵的功率较大，工频起/停泵时，对电网的冲击较大，影响其他设备的运行。采用变频控制后，水泵实现软起动、软停止，其电流均小于额定电流，对电网不再产生冲击。
减小停泵时循环水的水垂效应，由于是变频软停止，且停泵过程可控制，可以完全消除停泵时的水垂效应，消除水垂对空调系统管网的冲击。
（4）降低设备的故障率
采用变频控制后，循环水泵大部分时间工作在额定功率以下，这将有力的降低设备的故障率，减少设备维修和维护。
（5）提高设备的自动化程度
实现对循环泵的过载、过流保护
对冷水机组的冷却水、冷冻水的温度进行自动控制，保证机组的安全高效运行。 
综上，中央空调的循环水泵采用变频控制具有明显的经济效益，对系统进行变频改造非常必要。
