特点
文惠牌低温冷水机组根据不同温度要求大致分为H(高温),M(中温)，L(低温)三个系列，其冷媒蒸发温度分别为-10℃，-20℃，-50℃，不同系列机组所配置的压缩机及其他零配件均有不同，同一压缩机在不同工况下所产生的能力也不相同，因此选型时应找准相应工况所对的设备系列。为防止蒸发系统的冻水结冰，冻水系统必须添加乙二醇溶液，乙二醇的浓度不得低于20%（Ｈ系列），30%（Ｍ系列）或40%（Ｌ系列），以保障冷水机组的正常运转。根据客户的特殊要求，可定制于-60℃蒸发温度的机组。
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.
