　　冰(bing)蓄冷(leng)技能(neng)選用制冷(leng)劑直接與水(shui)(shui)進行熱交換，使水(shui)(shui)結(jie)成絮狀冰(bing)晶;一同生成和溶化進程不(bu)需(xu)二次熱交換，由(you)此大大前進了空調的能(neng)效。冰(bing)漿的孔隙遠大于固(gu)態冰(bing)，且(qie)與 回水(shui)(shui)直接進行熱交換，負荷照應功(gong)能(neng)很好。

　　冰(bing)蓄(xu)冷空調(diao)系統(tong)內部的(de)主要設備，如制冷機組、板式換熱(re)器和蓄(xu)冰(bing)槽內的(de)蓄(xu)冰(bing)盤管，在出時都(dou)已(yi)經過(guo)試壓查驗，且內部已(yi)處理潔凈.放不(bu)宜在系統(tong)裝置后與(yu)管道一同進行試壓和清 洗。

　　按(an)照規劃要求的(de)管路系(xi)統(tong)所(suo)應承受的(de)工(gong)作(zuo)壓(ya)力(li)，依據(ju)有關(guan)規范進行(xing)水壓(ya)試驗，)對管路系(xi)統(tong)進行(xing)嚴厲(li)的(de)清(qing)洗，用(yong)清(qing)水在(zai)管路系(xi)統(tong)內(nei)循環工(gong)作(zuo)1~2h,然后(hou)在(zai)低位排空，清(qing) 水注人系(xi)統(tong)多次(ci)清(qing)洗，直至管道(dao)潔凈。

　　在(zai)(zai)初度蓄(xu)冷循環期。有(you)(you)必要添加載冷保持低液位或(huo)系統壓(ya)力(li)這(zhe)是由于(yu)在(zai)(zai)初度蓄(xu)冷3~4h內，載冷利溫度逐漸下降至低點，體積也變為小(xiao)。對管道的(de)保溫絕(jue)熱(re)狀況檢(jian)(jian)查 其嚴密(mi)性:管道支架(jia)絕(jue)熱(re)功能杰出，不得發(fa)外殼結露和冷橋現(xian)象(xiang)。應(ying)守時檢(jian)(jian)杳一(yi)次封(feng)裝冰球有(you)(you)無(wu)磨(mo)損(sun)決裂現(xian)象(xiang)。在(zai)(zai)初步蓄(xu)冷前，應(ying)使循環泵(beng)工作24h，使載冷合均勻封(feng)閉制冷機，檢(jian)(jian)乙二醇溶液 流過蓄(xu)冷槽的(de)狀況，檢(jian)(jian)查是否有(you)(you)斷(duan)路現(xian)象(xiang)發(fa)作。

　　由于制(zhi)(zhi)冷(leng)(leng)劑與水直接接觸(chu)，兩(liang)種工(gong)質間(jian)的(de)傳(chuan)(chuan)熱(re)(re)(re)進(jin)(jin)程，不(bu)存在傳(chuan)(chuan)熱(re)(re)(re)間(jian)壁的(de)熱(re)(re)(re)阻及冰層增加發(fa)作的(de)附加熱(re)(re)(re)阻，因此可大(da)大(da)前進(jin)(jin)傳(chuan)(chuan)熱(re)(re)(re)功(gong)率(lv)，可以(yi)下降制(zhi)(zhi)冷(leng)(leng)劑與水之間(jian)的(de)傳(chuan)(chuan)熱(re)(re)(re)溫(wen) 差(cha)，削減不(bu)可逆傳(chuan)(chuan)熱(re)(re)(re)溫(wen)差(cha)丟失，前進(jin)(jin)制(zhi)(zhi)冷(leng)(leng)機組的(de)功(gong)率(lv)。
