Is the central air conditioner better with a branch pipe or a branch box?
27-12-2022
There are many opinions and reasons as to whether the central air conditioner is better in split pipes or split boxes. Let’s take a look at Zhu Guoqing’s article "Is the central air-conditioning better in split management or split box?" If you have any opinions, you can express your opinions at the end of the article.
I think our domestic decoration owners are a very difficult group. When choosing an air conditioner, they not only have to study whether the central air conditioner is better or the split air conditioner. , Japanese Daikin, Toshiba, Mitsubishi, Hitachi, domestic Gree, Midea, Hisense, there are more than N dealers under different manufacturers. There is a relatively common question-"Should the central air-conditioning be divided into separate boxes or divided into management", including the entire network, whether it is Zhihu, Tieba, Weibo or other platforms, there are many such questions.At present, the branch boxes on the market are mainly Mitsubishi Electric's Lingyao and some models of Shanghai Hitachi, and the branch pipes are mainly Mitsubishi Electric's Lingrui, Hitachi, Toshiba, Daikin and most domestic brand models.
1. What do branch boxes and branch pipes attack each other?There are also different opinions on the advantages and disadvantages of branch boxes and branch pipes, and there is no consensus. The points where the two attack each other are often:"The branching box is to eliminate outdated technology. Except for XX brand, no other brand is using it.""The welding of branch pipes depends entirely on the mood of the master. If the master welds well, it is okay, but if the weld is not good, it will be troublesome if it is leaked.""Branch boxes are available in European countries and Japan, and the cost of branch pipes is relatively high. In order to reduce costs in China, they are equipped with branch pipes."
There are actually quite a lot of such remarks. We have become accustomed to the mutual tearing of various brands. After all, the ass determines the head.For ordinary owners, those who are considering central air-conditioning, how to choose whether the central air-conditioning should use branch boxes or branch pipes?We would like to share with you what we saw and heard in Japan the year before last, so that you can judge for yourself. In 2018, Hitachi manufacturers organized some domestic dealers to study at Hitachi Shimizu factory in Japan. Many dealers prepared a lot of questions when they went, because Qingdao Hitachi does not make diversion boxes, and everyone hopes to hear about some Japanese factories. The reason for not making a branch box is that it is best to hear that the branch box is not as good as the branch pipe.When we arrived at the factory in Japan, we were received by a technical director of the Shimizu factory in Japan at that time, and asked us to ask some questions. I will briefly repeat them.First ask the Japanese: "Whether the branch box is better or the branch management?" At that time, there were translators. After translating this question for a long time, they were still quite surprised, probably because no one had asked them such a question before, and they understood it. Yes, the answer is "almost, almost the same", and then our dealers are not very happy, this answer obviously did not meet expectations, no.
Then they asked: "The branch box needs to be connected to the power separately, does it mean that it is not energy-saving?" Because the branch pipe does not need to stay in power, they replied: "It is almost the same, because the branch box has power, and the internal On the other hand, if you use a branch tube, the internal unit needs to save power, and the power consumption is very weak, and generally speaking it is about the same.” After saying this, I feel that this person is not very good. Knowing some situations in our country, the Japanese are more serious, what they say is what they say, there is nothing ambiguous, and our group is looking forward to having him give some absolute answers, but he just can’t reach ours expected.
Then someone asked again: "We know that the main engine with the branch box has a large liquid storage tank. Does this mean that more freon is needed, and the energy consumption is correspondingly higher, right?", this question is also After translating for a long time, they listened to it for a long time, showing expressions of sudden realization. We thought that the answer we wanted was about to come out, so we all listened with pricked ears. There are more freon, but less in other places, the branch pipe of the host with branch pipe has less freon, but more freon in other places, which is similar, and the energy consumption and electricity consumption are similar."This situation is more embarrassing, because we still haven't got the answer we want. We then started to ask: "Which branch box or branch pipe is used more in Japan?" The answer: "Almost, there are branch pipes and branch boxes in Japan."In this way, you can see that the final answers are almost the same. On the other hand, looking at our domestic central air-conditioning brands, basically the representative brands that use branch boxes are Mitsubishi Electric and Shanghai Hitachi, and the representative brands of branch pipes are Daikin, Toshiba, and Hitachi. Wait, the slight difference between branch pipes and branch boxes immediately rises to the difference between brands. In the current domestic market competition environment, the dealers' abilities are uneven, and dealers need the manufacturer's brand to provide trust and endorsement. Most of them are dealers who use product brands to compete with other brands. The phenomenon is still serious, and you can find out by searching the whole Internet.In the end, our group was quite disappointed. In the end, we still didn’t get the expected answer. In fact, the leaders who took us at the beginning also vaccinated us. Don’t ask them Japanese technicians Daikin Hao, Hitachi Hao or Mitsubishi Electric , Toshiba is good, there is no answer. The Japanese are relatively dull about these questions. For their philosophy, "the self today is better than the self yesterday". it is good.3. Personal views on branch boxes and branch pipesWhether it is a branch box or a branch pipe, it is just a way to transmit Freon. The central air conditioner has been developed for so many years, and it has been verified by the market for many years. If the branch box is better than the branch pipe, then there is a branch pipe. What's the matter? It would be nice for everyone to do the divergence box, and vice versa.
The market has been doing this for so many years. Although some people on the Internet will ask "is it better to split the box or the split tube?", it is basically a consultation without buying a central air conditioner. No owner will use it for a period of time and will say on the Internet, "" I use branch pipe air conditioner at home, the effect is better.” “I use branch box at home, and the air conditioner has never had any problems.” No one will say such a problem. In actual use, do you use branch pipe or branch box? It cannot be experienced. Even if there is a problem with a certain brand of air conditioner, they will still say that a certain brand is really garbage, not that a certain brand's branch box or branch tube is garbage.The branch boxes on the market are mainly Mitsubishi Electric's Lingyao, and Shanghai Hitachi's is relatively small, so it is difficult to find them. Taking Lingyao as an example, many Mitsubishi Electric salesmen will say that the branch box is a selling point, but Some people ask why Mitsubishi Electric's high-end model Lingrui uses branch pipes, and they will say that the main branch of Lingyao is used in villas, and branch boxes cannot cross floors. Is Xinglingrui not as good as Lingyao using a branch box? Is the imported ice flame using the branch box inferior to the Lingrui using the branch pipe? It's ridiculous to think about it with your heels.联系我们抬头
