600A制冷剂冰箱冰柜维修经验

600A制冷剂冰箱冰柜维修经验 看到好多论坛上关于R600a冰箱,柜,维修的问贴～大家对R600a也褒贬不一～或惧怕或谨慎或褒扬?????? 下面我就本人特约维修N台R600a冰箱,柜,为实践经验～和为维修献身的精神～亲自试验若干例“爆炸”威力后“幸存者”的角度来指导一下R600a的冰箱,柜,维修操作。 1.本贴适用于R600a的维修操作工艺。 2.R600a的制冷剂性质 R600a又名异丁烷,2-甲基丙烷,～属碳氢化合物～分子量为58～分子式结构为C4H10～R600a比空气重～很易聚积～无色气体～微溶于水～性能稳定～其臭氧消耗潜力=0～温室效应潜力=0。有别于以往的R12,R134a等制冷剂。它最大的特点是与空气能形成爆炸性混合物。爆炸极限为1.9-8.4%,体积比,～当达到或高于此比例时～如遇明火等即刻引起爆炸～所以安全是第一位的。 3.制冷系统的匹配要求 R600a压缩机 A异丁烷与传统的矿物油和烷基苯油完全相溶～故压缩机的制造工艺无须进行更改。 B.R600a压缩机的气缸容积在R12基础上增大65-70%～外形尺寸基本不变～对压缩机的泄露必须严格控制。 C.同R12相比～功率相同的电机所配压缩机的制冷量基本相同。 planning, and government financing, and whole village relocation, and first built Hou split" of principles, insisted big community planning, and large district transformation, break administrative divisions boundaries, optimization town spatial structure, speed up new Community construction, formed new community live building, and intensive with ground project, and enterprise tax insurance running, and Expand employment and improve people's livelihood shed changed economic chain.

Total demand is down to village, household, persons, County, town, and village books, card D.由于异丁烷的易燃性～必须对电器元件进行改动～R600a的压缩机的启动继电器应采用PTC元件且密封～绝对不能使用重锤式的启动继电器～R600a压缩机铭牌上有黄色火苗易燃标志。 系统热交换器 用于R12系统的冷凝器的蒸发器同样适用于R600a的系统～但需要作必要的匹配调整。 材料相容性 异丁烷与钢～紫铜～黄铜～铝～氯丁橡胶～尼龙和聚四氯乙烯相容～这些相容的材料均可用于R600a系统。硅和天然橡胶与R600a不容～故不能用于R600a系统。 毛细管 用于R12系统的毛细管同样适用于R600a系统～只是流量稍有区别。 过滤器 目前用于R12系统的干燥过滤器均可用于异丁烷系统中～生产维修中考虑到R600a的结构性质～要求使用专用干燥过滤器XH9。 充注量 异丁烷的冲入量相当于R12的40%左右～因此需要精度的制冷剂灌注设备～校准设备。 电磁阀 用于R12系统的电磁阀同样适用于R600a的系统。 planning, and government financing, and whole village relocation, and first built Hou split" of principles, insisted big community planning, and large district transformation, break administrative divisions boundaries, optimization town spatial structure, speed up new Community construction, formed new community live building, and intensive with ground project, and enterprise tax insurance running, and Expand employment and improve people's livelihood shed changed economic chain.
