l 高壓側容易造成壓力過高,增加壓縮機負荷,增加耗電。冷媒流速一旦過快,在毛細管入口可能反而阻塞,造成高壓側壓力持續增高,壓縮機負荷更大,電流太高,造成跳機。

簡單的講就是把冷媒從低壓壓力打到高壓,就跟水泵浦一樣, ... 所以即使因為冷卻水溫過高或是趨近溫度過高,主機在還沒達到高壓壓力跳脫之前是不會停止 ...

高壓過高有可能膨脹閥阻塞可開冷氣看防火牆邊的低壓管是否結冰,出風不冷出 ... 冷氣系統都沒漏的狀況下試試管路清洗,更換冷媒及冷凍油應該就能改善

低壓過高.壓縮機控制流量計更換.清洗更換壓縮機潤滑油及冷媒換新.又冷又有冷房效率冷氣不冷.冷媒表接上.高壓正常..低壓40幾PSI 當然不冷..低壓要10-30PS.

至於水是怎麼進去的我沒研究過,我猜可能是管路接口或壓縮機動力輸入軸工作時緩慢滲入。
