提高氨制冷装置经济效益的重要方向是防止油进入蒸发系统。分析国内外资料表明,油氨分离效率最高的属洗涤式油分离器(热氨蒸汽通过液体制冷剂层,借助其冷却和洗涤作用实现油氨分离)。但这种油分离装置的主要缺点是使自动放油复杂化,不仅放油要手工操作,而且并不总是能作到及时放油。全苏制冷工艺设计科学研究所北高加索分部研制成功了带有自动放油的10-MO型油氨分离装置。该装置利用了洗涤机构的良好特
An important direction for improving the economic efficiency of ammonia refrigeration plants is to prevent oil from entering the evaporation system. Analysis of domestic and foreign data show that the highest efficiency of oil and ammonia separation is a washing oil separator (hot ammonia vapor through the liquid refrigerant layer, with its cooling and washing effect of separation of oil and ammonia). However, the main disadvantage of this oil separation device is that it complicates automatic oil drain, which not only requires manual operation but also does not always result in timely oil drain. All Su Institute of Refrigeration Design North Scientific Division successfully developed a 10-MO-type oil and ammonia separation device with automatic drain. This device makes use of the special features of the washing mechanism
