更多Q＆A聚光灯
Levi Tofias是从他的波士顿地区家的肠道改造一年，他发现他的新MiniSPLIT HVAC系统是一个只有在天堂制造的比赛。
房屋位于5A的气候区，有2500平方英尺的条件空间，包括600平方英尺。在地下室。它的2×4墙已经用密集包装的纤维素隔热，内部有空气密封膜。新窗户是三釉，七农业单位提供全屋通风。
Now . . . to the root of Tofias’s unhappiness—the Mitsubishi multizone heat-pump system. As he explains in this最近的问答，它包括两个户外压缩机，额定30,000和42,000 BTU /小时，共有七个室内单位。（后来，在电子邮件中，TOFIAS将室外单位的容量纠正为24,000和36,000 BTU /小时。）
“My electric bills have been between $600-$700,” he writes. “We also had humidity issues this summer in cool mode. Basically, turning on the units would both cool and add humidity to the room, which meant adding between 5%-10% relative humidity.” This problem apparently affected units running on the larger of the compressors. (Tofias has attached both a floor plan of the house and the Manual J calculations for heating and cooling loads.)
“最后，”他补充说，“大型压缩机的室内振动和外部噪音变得无法忍受。听起来它是永久性的除霜模式。[我们]在市区，该单位是5英尺。来自物业线。邻居想杀了我。“
压缩机位于安装在房屋侧面的木框架上，但安装程序返回移动它。与此同时，TOFIAS关闭了大型压缩机，所以他可以睡个好觉。
What now? That’s the puzzle for this Q&A Spotlight.

对房主在这里有什么思考的任何想法？在这个过程中，事情会出错，可以提取哪些保障措施来帮助？例如，代码官方审查手册J？这些设计问题错过了什么？在该过程中的位置是检查点，以避免峰值加热系统设计的情况并不完全不适合冷却？设计软件是否突出显示此问题？如果我理解正确的MITSU的设计软件不会模拟多分裂上的最小容量，只有最大的容量，所以有很多猜测。
最后，鉴于设计可能已经完成了17°但没有超热量，在过程中可以/如果房主在常规和超热之间被告知房主的这种差异？想想贷款和利率的文件，似乎是必要的东西吗？
在我看来,HVAC许可作者ities should provide some assistance with such gross incompetence. Assuming the installer is properly licensed, there is more than sufficient evidence for discipline. Although each state is different, the licensing scheme exists to purportedly prevent stuff like this. It didn't work very well in this instance. But it's worth investigating the complaint process to determine if there may be a remedy to address the damage.
代码官员不审查手册J.手册J.手册J对可能或可能不准确的计算进行了大量的假设。我委托5手册J的工程公司，他们都越来越不同。归属主人始终卡在HVAC公司之间，这些公司将自动超大一切和不准确的手册J，这可能会让您留下。无论哪种方式都是赌博的。
This just makes me feel sick. I feel so bad for the homeowner
我也是。真是一团糟。
我最近有一个富士通龙眼安装在新的600平方英尺的APT中。它有一个压缩机和2头/墨盒（起居室和卧室）。
它有效地运行但有一个麻烦：如果同时运行，您必须在同一设置上运行2个头。例如，我不能在坐在风扇上加热客厅的卧室，反之亦然。
仍然很高兴我们选择了这种加热和冷却方法，只是烦人。
这是承包商严重无能的经典案例。对多区组合的练习核审查显然显示违反ACCA手册S.让我想知道承包商甚至是否知道手动S.
悲伤的部分是三菱可能会被归咎于失败。
When I read "What now?" the phrase "Gross Incompetence" was the second thing that came to mind, the first was "Sue 'em!"
I do not say that lightly and am seriously interested in GBAs opinion here. At what point does this constitute fraud? This case stands out to me in that Manual J documentation was provided and that is a clear implication that the ACCA design process was being followed. I can say with certainty the the Manual J above is incorrect and can guess with near certainty that the rest of the ACCA process was not followed. I am not a lawyer (and would really prefer not to involve one) but shouldn't the owner have some kind of recourse at this point? That system cost a lot of money. The installation may be impeccable but the design is completely wrong.
I know this is a rocky road and I'm not sure it's the right one to go down, but after seeing so little progress in the very troubled residential HVAC community over the years, the question should probably be asked. We're going to need all the good HVAC techs we can find the the coming years, but we also need good design of heat pump systems. Maybe a little sting to weed out those not willing is needed? Of course, there aren't nearly enough that are willing as it it is.
Thoughts?
Andy, the word for the day is incompetence. In the lawyer (truth twister) scheme, recall the quote from Chief Justice Warren Burger, “75% to 90% of American trial lawyers are incompetent, dishonest or both”.
我已经完成了专家见证40多年，并且可以说我只达到了一个主管的律师。大多数也是懒惰而不是很聪明。但他们没有任何问题收取50到100倍，而不是他们实际价值。
Litigation is obscenely expensive with no guarantee of an equitable outcome. At the end of the day, a plaintiff’s case is decided by 12 people who didn’t have enough on the ball to get out of jury duty. Or the judge reflecting the riddle - what do you call a lawyer with an IQ of 75? “Your honor”
The law doesn’t have a remedy for every wrong. And in most cases, the only winners are the lawyers.
