I don't usually spend much time in Zhihu. I was surprised to receive so many favorable comments. The comments were so-so, some answered and some didn't. As can be seen from the comments, there are those who agree, those who question and those who spray directly. So I added a broken line at the beginning to point out to those who want to read this article in the future. The central air conditioning mentioned in my article is only a small part of air conditioning, and the air conditioning system is actually a huge course. What you see is only the tip of the iceberg of the air conditioning system. What I mentioned in the article is only the central air conditioning of household fluorine system, the small multi-connection, or VRV, as the insiders say. Because the topics we are discussing are all Fortune 500 brands, and their products are being used in the homes of hundreds of millions of consumers. Some people in the comment area say that a brand they use at home is very good, some people say that a brand they use at home regrets, and so on ... Some people say that the same brand is good, and some people say it is not good. This is normal. If everyone says that brand A is good and brand B is bad, how can brand B become a well-known brand and be discussed? We must understand that we are not talking about questions with objective answers, let alone questions with standard answers, so we must understand the meaning behind my sentence. Everyone should understand that what I wrote was not a soft article. Some people immediately comment that it is a soft article of a brand when they see the beginning. Actually, it is not. I have given positive and negative comments to every brand, but some people don't want to see me criticize some brands. How can there be a perfect product? My criticism is not nonsense, you can look at it with a normal heart. There are too many brands, so write them when you have time. The content and format are a bit messy. I can understand what I can stand. I also apologize for those who can't bear it. Because there is no manuscript, I can write wherever I want. I try not to make people feel too messy.
