寒冷的气候热泵
有人对MRCOOL逆变器有任何运气吗？可以更换管道的燃气炉吗？https://mrcool.com/mrcool-dc-inverter-heat-pump-air-conditioner-split-condenser/
华盛顿州斯波坎的鳕鱼角风格。现有的燃气炉<80％的效率（我相信80年代末）。没有交流。大约1600平方英尺，有一些改进。地下室是R25，刚性绝缘，新窗户等。当前的炉子升起，然后循环很多。单速。公用事业成本不是疯狂的。与我见过的某些速度相比，水电和NAT气体价格便宜。
Did a Mr Cool minisplit with a neighbor in a 800sqft garage (remodeled into an art studio with some insulation, drywall, etc) and it worked great. Super easy and seems to work just fine year round.
大个子是在房子里得到一些交流电，以降低夏天的炎热。我们拖出窗户摇动者，刮擦旧的窗户壁架，每年做整个事情，永远不要期待它。
或者，查看Daikin的VRV双燃料设置，但这不包括我自己做。
Putting in the MrCool doesn’t look too daunting. I have prepped a sleeve for the lines, added power, pad, etc some time ago during the basement remodel.
大恐惧（最近）（最近）进入了0/5度，然后被巨大的电费击中，否则气体将会持续下去。

To right size it with a reasonable but not crazy oversize factor first one has to get a handle on the design heat load at the 99% outside design temp (which for Spokane is +1F- +13F, yes, I know it gets a lot colder than that sometimes:https://higherlogicdownload.s3.amazonaws.com/acca/c6b38bda-2e04-4f93-bd51-7a80525ad936/uploadedimages/outdooror-dooror-designimages/outdoore-design-conditions-1.pdf
Since there is a heating history on this place, run a fuel-use based heat load calculation:

SFAIK Mr.Cool doesn't have a ducted "hyper heating" vapor-injection scroll compressor unit (though they have some wall-coil type cold climate mini-splits) and without that technology even an inverter driven unit is likely to suffer capacity efficiency issues at temps below +10F. Daikin doesn't seem to either. A right sized Fujitsu ducted minisplit unit won't crap out at sub zero temps, nor will several Midea/Carrier ducted mini-splits with "hyper heating" compressors.
有管道的小型热泵可以处理此泵。但是提出负载号是重要的第一步。
三菱还设有一些导管单元，设计为替换传统炉的替换。
谢谢你们俩。我需要执行手册J/D（无论我作为房主做什么）。
I have access to all the gas and electric consumption for at least 10 years.
MRCOOL选项的一个有趣的方面是DIY，包括各种线路设置长度，以优化室内室内单元的距离。
达娜（Dana），我所引用的单位似乎与MITS Hyper Heath和其他有关冷性能的人都不相当。
I am sort of envisioning a ducted system that ramps up and down smoothly on a set point from a thermostat. How a mini split might work (but I don’t have a layout for that)
DIY系列的寒冷天气表现糟糕。看起来快速连接系统与蒸气注入压缩机无效。他们完全停止在5度下加热。我从MIDEA/先驱者身上绘制了一张绩效图表，该图表交叉引用了DIY模型。如果您搜索它们的广泛报道，它们具有可怕的供暖能力。他们开始在48度下失去加热能力。我的Midea Hyper热量在-13时为100％的容量作为比较。
Cool单位先生被重新审核。与实际上仅从MIDEA购买该单位的人相比，它们的价格过高，MIDEA的大部分名称品牌。
Do some research and you will see these units are actually quite simple to install. They are installed all over the world for dirt cheap compared to America. Costco and Walmart stock them on the shelves in Mexico for a couple hundred dollars. Going rate in Mexico is $50-100 to install one. They are cheap disposable appliances in most of the world. I self installed my $950 Midea Hyperheat unit. I could still buy 3 more for what a professionally installed Mitsubishi would have cost me. Worth the risk to me for the huge savings.
我读到DIY系列使用的快速连接系统实际上非常可靠。美国军方在伊拉克和阿富汗广泛部署了同一制度。可以迅速安装迷你拆分，而无需处理任何开放的制冷剂线或吸尘。沙污染也是一个大问题，该系统完全消除了它。
您处于部署热泵的最佳状态之一。据EIA称，西澳州的气候非常温和，在路易斯安那州之后，美国第二便宜的电力。你们有很多便宜的水力。我认为与天然气相比，它可能会更便宜。热泵的另一个巨大好处是，它们可以从太阳能电池板上电动。我有带净计量的面板，并用2 12k的迷你拆分加热我的房子。当您使用零化石燃料时，这种组合无疑是最干净，最有效的加热方法。看到我的电气监视器看到的微型拆分直接从太阳上供电，并将大部分电源发送回电网，真是太棒了。我以昨天数据的快照为例。
BFW，您可以澄清您与MIDEA的体验吗？您是说有一个产品线为DIY“插头和播放”设置，其性能数字较差，但可靠，然后有标准产品线需要熟练的线路工作组工作但性能很好？我花了一些时间冲浪在线商店，他们的文档可能有些模糊。
几乎。Cool先生制作一个带有快速连接配件的DIY的单位。该单元不是寒冷的气候单位。据报道，它是可靠的，并获得了不错的评论。一名军事HVAC人在一个有一个的HVAC论坛上发表了评论。他说，它们在阿富汗使用的完全相同的设置和相同的阀门。据称，快速连接配件是由美国公司制造的。甚至Costco都以1099美元的价格出售了Cool DIY单位，并获得了良好的评价。同一MIDEA单元与无需快速连接配件使用的MR COO DIYL使用的在线约为600-700美元。因此，您为快速连接拟合设置支付溢价。
Just remember though that these units would probably only work good heating in a place with a really mild climate. At 25 degrees the capacity is cut in half. So a 12k unit is only putting out 6k btus at 25 running full speed at poor efficiency. These would be terribly inefficient here in New England and a good chunk of the Northern US that experiences decent cold. If you just want one for cooling they are fine and have great performance.
MIDEA是世界上最大的空调和设备制造商。他们在这里与运营商合作，但市场份额很小。MIDEA几乎所有这些都不是Cool，Senville，Pioneer等人的品牌。我的中层控制台单元与Daikin，Fujitsu和其他品牌相同。看来他们都可能来自同一工厂。MIDEA正在获得DIY安装的人的日益普及。他们的主要高温系列12K单元的价格为950美元，运到您的房屋中。它的价格接近大人物，例如三菱，而且表现相似，而且表现更好。希腊第二大中国制造商目前正在根据AHRI数据生产最有效的迷你拆分。
Interesting... I wonder if Midea is the OEM for the Alize heat pumps bundled with Dettson Chinook furnaces? One of the many reasons the Dettson Chinook furnace is appealing is that it comes with a heat pump system instead of just an air conditioner. The downside to their heat pumps is they don't have great low temp performance; the 24KBtu unit only heats to about 20F and is down to 55% capacity at that temp.
如果MIDEA是OEM，我想知道是否可以将其超级室外单元之一代替标准Alize模型？以下是系统和技术信息的链接：

https://www.dettson.com/wp-content/uploads/2015/01/X40228M_COND-09-12-18-24_EN.pdf
I'd love to have a system that allowed electric heat most of the year, even if it meant relying on gas during really cold temps. I'm in Ottawa with a design temp of -13F, so a hyper heat pump is about the only thing that would work here.
多数民众赞成在一个受重新的Gree Terra。这是Thr Gree Terra服务手册。它与您链接的Dettson服务手册相同。您还可以视觉上看到它们是相同的。
China is notorious for one or 2 big companies producing most of the same products with different brands slapped on them. I have a 50cc chinese scooter. They are all built in 2 huge factories by the same company then a dozen or so companies put some stickers on them and export them.

回复BFW，发布＃9
太好了，感谢您提供的信息！
Funny, the heating performance chart looks very similar, but the Gree manual actually specifies reasonable low temp heating performance (70% capacity at 0F).
我想知道Dettson手册中的信息是否不正确？如果这是因为热泵的性能是令人沮丧的，尤其是一个被销售并出售给加拿大人，这不会令我感到惊讶。
>“您是部署热泵的最佳州之一。WA具有相当温和的气候，是在路易斯安那州之后的美国第二便宜的电力。”
Spokane is on the cool edge of US climate zone 5, not a super cold climate but hardly "mild".
It's nowhere near as temperate as the western half of the state. It still calls for a cold-climate type compressor, not one of the Mr. Cool DIY types. I don't believe Mr. Cool has a DIY-ducted version either (not that I check their lineup very often.)
But electricity IS pretty cheap there (relative to most of the US.)
如果您可以找到具有工具体验的交流承包商，可以正确地泵下/清除系统并安装适当的制冷剂费用，则可以作为“主要是DIY”的安装来做一个正确的高加热管道调节管道调节或Fujitsu。
我有一个 - 但不是快速连接版本。Ama。在我将其从地面寒冷的天气中进行6英寸左右，NJ -99％= 15摄氏度很棒。性能似乎比规格好一些，但更重要的是：
1）青少年的能力很好 - 最小的除霜周期。
2）让我的家庭房和厨房比以前的水力系统温暖约10度，当时它的价格在数十个中时，价格也不略低。
3）在温暖的日子里，当40多岁时，它的其余部分也使房屋的其余部分保持温暖，费用最低。
总的来说，我对此感到满意 - 但是说我现在知道的是，我会得到更高的先知/HPSR单位Midea敲门 - 就像Senville，Pioneer或Blue Ridge一样。它们都是相同的 - 但是，您肯定可以以与Cool先生相同的价格获得更好的性能。
例如先锋有21个预言家,HPSR 12单元for around 800 at Highseer.com. Plus it has some subzero performance as well in case you need it.
Some good info everyone, thanks.
听起来像是快速连接DIY功能将一些冷性能功能从桌子上推开。
杰伊，你是安装了安装，然后有人做线路的部分吗？
亚马逊安装服务。他们从纽约（约30英里外）派出人们。他们非常专业，如果您在该地区，我可以直接推荐该小组。
我想我可以self but the price wasn't bad. And they came within a week and did the job with 3 people in half a day. They were originally from outside the US so they had a lot of experience with mini splits.
另外 - 他们确实必须在预付的线路上排名第一，因此请注意，它们并不总是准确地填充。（当然很难说你是否DIY）
Only problem was they kept the pump on the ground, so first freeze I had the "igloo effect" - but once I got it off the ground it's been running great.
因此，您从亚马逊购买了该装置并订购了安装？
请记住这一点很有趣。我一直在minisplits中听到的问题之一是找到当地人安装它的问题。
Yes - logistically it was very helpful since we had a 100 degree heat wave and Prime got it to me in a couple days and the installation within a week.
But if you have time, buy from highseer or another distributor online. (Each "brand" has it's own distributor, but they are all Midea's - they use the same apps, USB interfaces, connect to Alexa the same way, etc.)
这些事情是有效的。昨晚的温度处于20年代的低位，因此您可以看到今天早上25岁左右的临时温度从65-75 f升高。它使用大约1.5 kW的功率来做到这一点。
Never thought of amazon. And your point about the precharge not being full was something I had thought about and something you wouldn’t know if you diy.
Wait, so you guys are talking about ordering a minisplit AND the installation AND the commissioning (lineset charging) on Amazon? Like, Amazon.com the website??? And that's a thing??
我想知道这是如何在我的脖子上放在树林（俄亥俄州乡村）的。它比在线价格高30％，但我认为保修值得。我完成了整个安装，包括运行线路和进行所有电气连接。然后，他们的技术收取了近600美元的费用，以连接线条并进行加压。（他一直在喃喃地说，我用12 kbtu minisplit代替80 kbtu炉的可怕错误，但这是另一个故事）。
我只是对听到替代方案非常感兴趣！

This proclaims to not need supplemental down 0 degrees. If does have an optional heating element.
我知道1：1室内到室内单元是首选的，但这看起来好像可以使用现有系统来运行管道部分，如果我们选择添加一个小型添加，我们可以添加一个小型的Minisplit，并给3张床/喂食3张床/1浴在二楼。
We have two 6” runs from the furnace to the .5 second story (essentially two small bedrooms). Those runs would be pointed down through the ceiling on the first floor and the second indoor unit could run the second floor (with addition) exclusively. Seems like it might work.
Daikin单元不是寒冷的气候版本，并且很快就会以低于0f的容量来垃圾。Daikin容量曲线的膝盖，其能力开始在 +10F以北的更好的东西上开始更加陡峭的七个，而使用蒸气注入冷气候型压缩机，它仍然很好 +5F，并且通常具有75-80％或更多的“额定”容量为-10F。
西澳大利亚州的大部分地区都对三菱（至少在喀斯喀特的西部，我的亲戚都活着的亲戚）都有很好的分配和支持，对斯波坎不确定。重要的是要有至少一定数量的本地安装程序知识（分销商支持更好），如果Daikin在西澳东部有足够的市场份额以获得足够的支持方式，我会感到惊讶。运营商出售重新标记的MIDEA单元，如果它们是重新标记的型号，则承运人支撑链可能能够为MIDEA提供服务。
但是，在更好地理解负载编号之前，所有这些都有点愚蠢。缺少手动J，您是否愿意运行基于燃料的热负载计算？

What's the story on these? Seriously, they claim 100% heating capacity at -5F. 78% capacity at -22F.
2吨的20先知和11HSPF。它具有将其设置为3顿的倾角开关。通过此设置，这是替换1亿座房屋的替代品的上升。我要再订购2吨富士通，我认真考虑这样做。How are they doing this?
https://mrcool.com/mrcool-universal-series-dc-inverter-heat-pump-air-conditioner-split-system/
also, they seem to be better at marketing than everyone else I've seen.https://www.youtube.com/watch?v=_v8vizQXwss

其中的一部分是“能力”的定义。他们指的是AHRI的“额定值”能力，而不是在室内70F的AHRI测试温度下的最大容量。
为了获得-22F的合理能力，他们必须使用类似于Fujitsu＆Mitsubishi等的蒸气注入类型压缩机技术学。
2吨富士通和2吨酷先生的通用先生之间的一个区别是，富士通通过负载调节了空中速度和压缩机速度，而Cool Mr.Cool Air处理程序是单速度（在某些方面与三菱MVZ系列空气处理程序相当。）我没有在空气处理程序的手册中找到CFM或静态压力规格。2吨和3吨压缩机都使用相同的空气处理程序，控制板上的DIP开关设置为空气处理程序，以适当地设置其参数。
根据我在线阅读的内容（对于MR Cool），在2吨和3吨的1000 cfm上为900 cfm。
We have Carrier around here. Commercial and residential. Perhaps I can dig into the Midea units a bit. I need to redo my numbers though since we have fully insulated walls in the basement now.
What I found though is that when I got some local quotes they basically all charged same $6-7k and the proposals were all the same - gas furnace, conventional AC compressor outside.
The 2 to 3 Ton MrCool Universal Air Handler is variable. Which is the only thing that makes sense for AC with a variable compressor.
I haven’t seen anything about an ECM motor in the handler for the Mr Cool solution. Some literature suggests that the units are ‘non communicating’ - so the outdoor unit doesn’t speak with the indoor at an advanced level?
Maybe "variable" only refers to the 2 vs 3 ton selection done at installation and then it is a single speed? It's poorly documented - needs to disclose modulation range on both parts.
因此，在这里的此网站上，他们有更多细节，它们的视频或两个视频显示了一些令人印象深刻的寒冷天气表现。https://iwae.com/shop/2-to-3-ton-18-seer-variable-speed-mrcool-universal-central-heat-pump-split-system-upflow-horizontal-ha20919.html
它意味着处理程序上的变量输出。因此，我想有可变的压缩机输出，可变空气处理程序CFM，然后可能会变制冷剂流量吗？我想这与压缩机调制有关吗？
在-24F视频中，性能图看起来只是以全功率打开和关闭，似乎并没有调节。
I think there was another post here recently where the person called Mr Cool and they confirmed it was made by Midea.
冷性能规格似乎与Midea Premier单元相同，并且可能具有东芝蒸气注入压缩机。
I have a Midea Premier floor console and it came in a Midea Carrier North America box from Georgia. There were both Carrier and Midea Midea stickers in the box.
Lance-我注意到了这一点，但是我正在浸入这些浸入时，就像它进入除霜模式时一样吗？他们处理的天气比我们在这里的天气更寒冷（华盛顿州斯波坎 - 冷却96，加热10）。
IIRC he made reference to a defrost event just before the unit turned on and stayed on for the night. My impression was the defrost event looked different than the pulses before that, but I’d have to watch again to be sure.
如果该视频是对其性能的准确描述，它似乎肯定会很好。话虽如此，我们不知道房屋的实际热量是多少，或者HP的性能有效。
有某种“营销”感觉...谁在乎寄存器是否温暖？这是我们关心的房子。绝对针对房主，而不是HVAC专业人员。
