制冷機(jī)通過(guò)壓縮機(jī)將制冷劑壓縮成液態(tài)后送蒸發(fā)器中與冷凍水進(jìn)行熱交換，將冷凍水制冷，冷凍水泵將冷凍水送到各風(fēng)機(jī)風(fēng)口的冷卻盤(pán)管中，由風(fēng)機(jī)吹送冷風(fēng)達(dá)到降溫的目的。經(jīng)蒸發(fā)后的制冷劑在冷凝器中釋放出熱量，與冷卻循環(huán)水進(jìn)行熱交換，由冷卻水泵將帶來(lái)熱量的冷卻水帶到散熱水塔上由水塔風(fēng)扇對(duì)其進(jìn)行噴淋冷卻，與大氣之間進(jìn)行熱交換，將熱量散發(fā)到大氣中去。
舊操作系統(tǒng)為“星-三角轉(zhuǎn)換起動(dòng)”全壓運(yùn)行，此時(shí)空調(diào)機(jī)組在滿負(fù)荷狀態(tài)下工作，系統(tǒng)在起動(dòng)電機(jī)時(shí)不能平滑起動(dòng)，起動(dòng)時(shí)對(duì)電網(wǎng)沖擊大，長(zhǎng)時(shí)間頻繁起動(dòng)將造成電機(jī)的絕緣性下降，電機(jī)溫升過(guò)高，在運(yùn)行過(guò)程中不能有效的根據(jù)病房與辦公樓的需求，對(duì)溫度進(jìn)行有效的調(diào)節(jié)，只能工頻最大量進(jìn)給，這將勢(shì)必造成能量的浪費(fèi)。
而通過(guò)變頻頻改造后，能根據(jù)房間的制冷及制熱的需求自動(dòng)調(diào)節(jié)冷凍泵及冷卻泵的流量而達(dá)到節(jié)能降耗的目地。
（1）由于目前冷卻水循環(huán)泵為工頻滿負(fù)荷運(yùn)轉(zhuǎn)，在制冷周期的前期和后期，環(huán)境溫度較低，冷卻水回水溫度較低，會(huì)造成溴化鋰結(jié)晶，導(dǎo)致空調(diào)機(jī)組效率降低，甚至保護(hù)。采用變頻恒溫差控制后，回水溫度得到有效控制，將大大提高空調(diào)機(jī)組的效率，達(dá)到節(jié)能目地
（2）由于冷凍水循環(huán)泵也在工頻滿負(fù)荷運(yùn)轉(zhuǎn)，而不能根據(jù)室內(nèi)溫度的要求自動(dòng)調(diào)節(jié)流量，而通過(guò)變頻改造后冷凍泵能根據(jù)室外溫度及室內(nèi)溫度要求能自動(dòng)調(diào)節(jié)流量，提高效率，達(dá)到節(jié)能目地。
（3）減小空調(diào)開(kāi)機(jī)、停機(jī)時(shí)對(duì)供電和系統(tǒng)的沖擊
減小空調(diào)開(kāi)/停機(jī)對(duì)電網(wǎng)的沖擊，由于循環(huán)水泵的功率較大，工頻起/停泵時(shí)，對(duì)電網(wǎng)的沖擊較大，影響其他設(shè)備的運(yùn)行。采用變頻控制后，水泵實(shí)現(xiàn)軟起動(dòng)、軟停止，其電流均小于額定電流，對(duì)電網(wǎng)不再產(chǎn)生沖擊。
減小停泵時(shí)循環(huán)水的水垂效應(yīng)，由于是變頻軟停止，且停泵過(guò)程可控制，可以完全消除停泵時(shí)的水垂效應(yīng)，消除水垂對(duì)空調(diào)系統(tǒng)管網(wǎng)的沖擊。
（4）降低設(shè)備的故障率
采用變頻控制后，循環(huán)水泵大部分時(shí)間工作在額定功率以下，這將有力的降低設(shè)備的故障率，減少設(shè)備維修和維護(hù)。
（5）提高設(shè)備的自動(dòng)化程度
實(shí)現(xiàn)對(duì)循環(huán)泵的過(guò)載、過(guò)流保護(hù)
對(duì)冷水機(jī)組的冷卻水、冷凍水的溫度進(jìn)行自動(dòng)控制，保證機(jī)組的安全高效運(yùn)行。
綜上，中央空調(diào)的循環(huán)水泵采用變頻控制具有明顯的經(jīng)濟(jì)效益，對(duì)系統(tǒng)進(jìn)行變頻改造非常必要。
