中央(yang)空(kong)調循環水(shui)(shui)(shui)泵(beng)(beng)變頻柜廠(chang)家(jia)：空(kong)調水(shui)(shui)(shui)系(xi)統設(she)計時，中央(yang)空(kong)調循環水(shui)(shui)(shui)泵(beng)(beng)選型是根據(ju)制冷機的(de)最(zui)大(da)制冷量所需水(shui)(shui)(shui)量以(yi)及管系(xi)的(de)具體情況，再乘以(yi)一(yi)定(ding)的(de)安全系(xi)數確定(ding)水(shui)(shui)(shui)泵(beng)(beng)的(de)功率、流量及揚程。所以(yi)循環水(shui)(shui)(shui)泵(beng)(beng)在(zai)(zai)設(she)計上存在(zai)(zai)著一(yi)塊設(she)計余量。制冷機絕大(da)部(bu)分(fen)時間運轉在(zai)(zai)部(bu)分(fen)負(fu)荷(he)的(de)狀(zhuang)態(tai)，而循環水(shui)(shui)(shui)泵(beng)(beng)卻是以(yi)制冷機最(zui)大(da)負(fu)荷(he)時的(de)工況運轉，并且造成了循環水(shui)(shui)(shui)泵(beng)(beng)大(da)量電能的(de)浪費。
中央空(kong)調循環水泵變頻(pin)柜廠家變頻(pin)供(gong)水系統(tong)的(de)優點和特(te)點
1、從電(dian)源取用的(de)能量最小，節電(dian)效果最為明顯，比傳統供(gong)水方式節電(dian)25~50%。
2、用(yong)水壓力(li)是根據用(yong)戶的(de)實際(ji)需要設定的(de)，節水效果也很明顯。
3、供水(shui)壓(ya)力(li)恒定(ding)，調節精(jing)度高，供水(shui)質量好，系統(tong)在設(she)(she)定(ding)壓(ya)力(li)下長(chang)期工(gong)作(zuo)的誤差僅為5%，對(dui)延長(chang)設(she)(she)備(bei)及管(guan)網的壽命極為有益。
4、全(quan)自(zi)動運行，無(wu)需人工值守，管理(li)簡單(dan)，節省人力。
