特點

文惠牌低溫冷水機組根據不同溫度要求大致分為H(高溫),M(中溫)，L(低溫)三個系列，其冷媒蒸發溫度分別為-10℃，-20℃，-50℃，不同系列機組所配置的壓縮機及其他零配件均有不同，同一壓縮機在不同工況下所產生的能力也不相同，因此選型時應找準相應工況所對的設備系列。為防止蒸發系統的凍水結冰，凍水系統必須添加乙二醇溶液，乙二醇的濃度不得低于20%（Ｈ系列），30%（Ｍ系列）或40%（Ｌ系列），以保障冷水機組的正常運轉。根據客戶的特殊要求，可定制于-60℃蒸發溫度的機組。

Wenhui series of low-temperature water chiller can be divided into three series: H(high temperature), M(medium temperature), L(low temperature) which evaporating temperature is -10℃/-20℃/-50℃. Different compressors and other parts make up different series of chillers. The same compressor in different conditions is not the same, so choose the proper chillers according to the detailed requirements. In order to prevent the frozen of water , ethylene glycol needs to be added to the cooling system. The concentration of ethylene glycol can not be less than 20%(H), 30%(M), 40%(L) in order to ensure the normal operation of chillers. According to customer’s specific requirements, chillers with evaporating temperature less than -60℃ can be made.
