- Note: Whitmore's Ammonia Compressor Oil is not intended for use with freon refrigerants or in systems that operate at temperatures below their pour point. 注意:威特魔力氨压缩机油不可以用于用氟里昂制冷系统或工作温度低于本产品倾点范围的系统。
- Hydrocarbons such as propane (HC290), butane (HC600), isobutene (HC600a) etc. have zero ODP, small GWP, and excellent thermodynamic property, and they are natural substances. So they are good alternatives of Freon refrigerants. 碳氢化合物类制冷剂如丙烷(HC290)、丁烷(HC600)、异丁烷(HC600a)等ODP值为零,GWP值很小,具有很好的热力学特性,且为天然物质,因此是一种很好的氯氟烃制冷剂替代物。
