嘈杂的Minisplit
之前我叫三菱保证我只是想运行这个由你们,看看你们有类似的经验,知道发生了什么…我有2三菱超迷你热将安装在我新建的“不错”使用一mini-split楼例行公事。这对我来说效果很好。楼下是12K，楼上是9k。墙上挂载。楼上的单元从第一天起就完美无缺。这不是一个多头系统。他们都是单独的头在自己的户外单位。楼下的单位工作得很好，但有个问题，它很少(但确切的时间很难确定，因为我并不总是在家)。但是我想说我注意到大约每周两次)(我从来没有注意到楼上头)楼下头会做奇怪的水或制冷剂沸腾的声音有些奇怪的吱吱作响,发出嘶嘶声不是真实的声但如果你坐在沙发上看电影会使你回头看看发生了什么。我第一次注意到这种噪音的时候绝对是最糟糕的时候。 The first time it was slightly louder than when it does it now and the head stopped producing heat until I flipped the breaker and “reset” it. This resolved both issues. This first time I immediately called the contractor I had install them and he came right over and checked them out and verified everything was fine with them as far as refrigerant amounts, line pressure etc. Of course there’s a possibility those things are not actually correct because as we know contractors aren’t always the most honest especially when it comes to warranty repair work. However after he left it’s never been as bad as the first time again….??? So I don’t know if he actually changed something and just didn’t tell me. Anyways since then I’ve called him and even send him a video recording of the noise with his response being there’s nothing more he can do and it’s on me to call Mitsubishi factory warranty hotline. I just haven’t had the time to deal with what I know is going to be a long ordeal so I have not made the move to call Mitsubishi yet but I figured on the off chance that if this is some kind of a normal defrost routine or something like that I should probably ask those who have been living with them longer than me. Also as a side note the downstairs unit line set runs in an “open” space under the stairs which allows me to listen to the lines directly unlike if they were in a wall. When it does this noise situation I can go under the stairs and hear fluid moving/bubbling in the lines. Any ideas?

听起来像是正常的解冻周期。我不会重启断路器，让它完成循环。热总是会回来的，对吧?
这就是融霜周期。室外机上结了冰，所以它会逆转制冷剂流动，实际上加热了外部盘管，融化霜。这也意味着，在这10分钟左右的周期内，它实际上将处于非常温和的“冷却模式”。这是完全正常的，当天气非常恶劣(雪从侧面落下)时，我的车有时会每小时运行一次左右。
谢谢你们的回复…解冻周期应该有多大?我楼下的单位大约等于炉子上烧开的一锅水。楼上那个我从来没听过，就在我卧室外面....??
室外机应该是这样的:

室内应保持安静，直到循环结束。当它重新启动时，你会听到制冷剂的声音。在冬天，楼上的设备不像楼下的设备那样辛苦工作，所以它不会经常解冻。
解冻应该不是一件罕见的事情。我的热泵在14个月里运行了3050小时，共融霜265次。我第一次注意到的时候，管道工就在那里，我们都在寻找破裂的水管，因为它听起来像流水，后来变成了沸水的声音。我的解冻周期大约持续3分钟左右。

遗憾的是，热泵还没有达到除霜周期的峰值声音级别。我们的标准分体机组在除霜周期中偶尔会在压缩机上发出明显的短啸声，尽管它不会像在旧管道(以前的电炉)中在1000 CFM+的15千瓦热条喷砂那样让我醒来。
我一直听到这样的噪音，听起来是我的三菱内墙装置的一个良好的除霜周期，它开着空调模式。我以前从来没有看过，我还没有看过，只是好奇而已
