Solar rain solar 18 branch tubes, tube length 1 8 meters pipe diameter 58 frequency conversion tube

Our family sells sun and rain, and I don't know much about frequency conversion! I'm sorry, the Antarctic is 2900 yuan insulation wall (just the price of our family, but I don't know about other houses)!!

This should go into the professional ** inquiry, if you are in a hurry, it will be a waste of time!

Hope you can find it!

Listening to these names is a hype concept.

How to distinguish the authenticity:

The vacuum tube is the core component of solar energy, just like the "engine" of the car, the human heart, if the thermal performance index of the vacuum tube can not be reached, it will not take a year, and the solar energy bought back will become a "chiller", which is very painful. The ordinary vacuum tube you see is the same as the outside of the vacuum tube of Huangming, but I suggest that you identify the solar vacuum tube from the following four aspects: look at the color:

The inner tube of the ordinary vacuum tube is not black enough, and the inside can be seen very bright with the naked eye, which will cause the absorbed heat to be reflected back, and the thermal efficiency becomes lower. Three listen to the voice:

Knock it, the sound is very different, the sound of a good pipe is very brittle, and there is an aftersound, and the sound of an ordinary pipe is muddy and there is no echo. Four tests of solidity: Huangming's tube diameter is 30 meters of steel balls, if it falls vertically from a height of 50 centimeters, the vacuum tube will not break.

You can look at the anti-counterfeiting mark on the glass tube.

It must be the Antarctic tube is good, think about it, **are all a big difference, pay attention, the sun and rain are all expensive are equipped with the Antarctic tube, rainy days can get hot water, as for how big the water heater to choose, this depends on your water habits, some saving, with 18 tubes can get 4-5 people, waste 18 tubes are not enough for two people, generally speaking, a family of three to choose 18 tubes on the line, here to provide some parameters of the capacity of the solar rain heat wall series, 16 tubes of water tank net capacity of 123 liters, 18 tubes of water tank net capacity of 140 liters, 20 tubes of net capacity of 157 liters, vacuum tube each tube liter, it should be noted that I talk about the net capacity, now a lot of miscellaneous solar energy on the market say that most of the water tanks contain the water in the vacuum tube, in fact, you can't use those water, so most of the solar energy you may usually see has a large standard capacity, 18 tubes have more than 200 liters of water, in fact, that is misleading you, you should be careful to identify, the sun rain water tank has a standard capacity, that is the net capacity, It does not include water in the vacuum tube. As for the good purchase, I suggest that you buy the solar rain heat insulation wall or BID series, which are all used in the Antarctic tube, both have heat insulation walls, and they must be easy to use; As for the service life, it is almost the same, it is more than 15 years, but the effect is not the same, whether the vacuum tube is good or not, not only depends on his service life, but also depends on whether his heat gain rate is high, otherwise if it is the same, why should the brand-name products be divided into different price points such as three, six, nine, etc., and the cost performance is always proportional.

In the initial stage of solar water heaters, there are still many people who believe in the frying of vacuum tubes. It's like manufacturers frying thermal underwear many years ago. Sooner or later, this lie will be revealed.

It is still recommended that you buy a cheap one. Sun Rain also has a cheap series. You ask if the cheap ones can be used, and how much difference is there between the service life and the good ones.

If he says that the life span is the same, he is telling the truth, and if he says that it is different, he is lying to you. Because the longevity of the tube, regardless of the type of tube, is due to the fact that the inert gas in the air can penetrate the glass, an absorber must be placed in the vacuum layer in order to maintain a high vacuum. And the amount of placement is the same.

That's fifteen years. In terms of thermal efficiency, it is also similar. He will say that the small tube is not good, in fact, you can see that the number of small tubes is more, and the number of large tubes is less, and the ratio of heat collection area and water tank is the same.

That is to say, the tubule is as hot as it gets.

In fact, there is no difference, this is just the manufacturer's ** strategy, and it is enough for three people to use 18 tubes.

The vacuum tube is the heart of solar energy, just like the human heart, the engine of a car. So choosing a vacuum tube is key. Please refer to my previous one for how to choose a vacuum tube.

The most terrible thing is to only count the number of vacuum tubes when buying solar energy. Excuse me, do you know how many liters of hot water can be supplied by binhua001 18 tubes? So, the second key point you have to choose is how many liters of hot water the tank can provide and whether it can meet the needs of your home in winter.

When choosing the size of the solar energy, please refer to Huangming's advice.

Let's make a regional difference! It may not be the same, we have 100 yuan here.

Questioner. Despise those black-hearted advertisements that mislead consumption!

Solar power generation, power generation per square meter is about 120w, the cost per square meter is about 1500 yuan, and the larger the area, the lower.

In 2013, the photovoltaic industry was investigated by the anti-monopoly of Europe and the United States, and overcapacity led to the collapse of a large number of photovoltaic industries in Zhejiang. This can be checked online at any time.

It is recommended to buy solar water heaters** each priced at 150-180 yuan, including other costs such as materials and materials.

The Antarctic tube is dark black-purple (it looks black when it is not lit, and it looks purple when it is illuminated). It is usually dark blue. The Antarctic tube is mainly used to absorb heat and retain heat.

Solar water heaters, looking at the color of the tube is not of any use. The so-called Antarctic tube is just a matter of what would happen if it were in the South Pole. However, Huangming's winter crown machine has already "bubbled" hot water in Antarctica.

The really easy to use solar water heater is still Huangming's Dongguan original integrated series of solar water heaters, which is an expert in hot water in winter.

The current market for solar products is mixed. Consumers will fall into the ditch if they are not careful.

When shopping for a solar water heater, please note:

1. See whether the number of the vacuum tube and the water tank match. 58 Long vacuum tubes can heat 8-10 liters is preferred. After all, the purpose of buying solar energy is to use how many liters of hot water you need, not the number of vacuum tubes.

Nor is it that the higher the number of threads in the vacuum tube, the higher the water temperature. The number of threads of the vacuum tube is large and the capacity of the water tank is small, indicating that the heat collection capacity of the vacuum tube is very low. For example, an 18-meter vacuum tube can only collect heat to obtain 140 liters of hot water (the capacity of the water tank), while another 18-meter vacuum tube can collect heat to obtain 180 liters of hot water, indicating that the latter vacuum tube has a strong heat collection capacity.

Such a vacuum tube is a good vacuum tube.

2. Use a lighter to burn the bracket to see if the paint of the bracket is baked. Painted brackets will change color after two to three years outdoors. The scaffold resembles a human skeleton.

3. Three points of products, seven points of installation. Installation is key. The key to whether solar energy is good or not is the key. The installation should leave no room for thermal insulation and anti-corrosion measures. Especially in the north, the electric belt must be of high quality, otherwise it will cause a fire and cause endless troubles.

These are provided for reference only.

Don't listen to the blind flickering of these Antarctic tubes and Arctic water, most of the ordinary scattered tubes on the market have reached more than 92%, and the vacuum tube heat collection efficiency of big brands of solar energy has reached 93 95%, how to improve the efficiency? Is it worth paying a few hundred yuan for that 1% increase?

Besides, can the name of the Antarctic tube really increase this 1%? Three of the top four brands in the solar industry are Linuo tubes. Linuo started as a vacuum tube, although the quality of Linuo tube is high, but the quality is quite stable, and it has been tested by the market for nearly ten years (listed company, I heard that the technology is in cooperation with Germany, I don't know whether it is true or not, it is difficult to say anything).

The use environment of solar energy is very harsh, and a new pipe, which has not been tested by the market, can ensure that it will be exposed to the wind and sun on the roof for more than ten years, and the effect will be consistent?

The current water heater market is all about materials, processing technology, after-sales service and enterprise strength. The water heater itself is not too complicated technology.

The last sentence, now is not dozens of people, a dozen guns, can make a high-tech era, no strength support, no years of professional manufacturing experience accumulation, and then dazzle consumers with new technology and new terms, in the final analysis, it is two words: flicker!

The quality is not good, and the "thermal wall" is not effective at all on a rainy day, let alone in winter. Only when you turn on the "fully automatic" function, there may be hot water on rainy days, but turning on the "fully automatic" function means that solar energy is consuming electricity for heating on rainy days, so it is equivalent to an electric water heater. That is to say, only when you turn on the "fully automatic" function, can you achieve the "heat wall" effect advertised by the sun and rain, but on the other hand, if you have to turn on the "fully automatic" function for heating, does that mean that the temperature is very high on rainy days is not the so-called "heat wall" in heat retention?

Thermal walls are just hype.

Sun Rain Solar Appliances Go to the Countryside Sun Edge Series: 58 2000 24 **: 4800 yuan Subsidy amount: 520 yuan 4280 yuan after subsidy.

It depends on the weather, the summer is sunny more than 30 degrees, the water temperature is 99 degrees, and the winter is a little lower; The temperature is directly proportional to the temperature of the sun and the length of daylight, so it is difficult to determine how small a day can be.

18 tubes of solar rain antarctic solar energy currently**: the maximum is 2200, the minimum is 2050, and the average price of general merchants is 2100 yuan. I visited several stores the day before yesterday and was going to buy one myself.

What model? That series?

Thermal insulation wall, antarctic tube 180 20 = 3580 yuan. 180 18 = 3380 yuan. 180 16 = 2950 yuan. Nationally unified**.

The cheapest is also the Moon Rain series. Only 1061 yuan.

Xiayi Li set sun rain store.

More than 3,000 is very expensive, the quality is almost the same as the ordinary one, it is better to buy the imperial name or the brilliant one.

Definitely the Antarctic tube is better, the Antarctic tube refers to the series of tubes that produce hot water at -40 degrees in the Antarctic experiment, the film technology is better, and the heat absorption capacity is stronger.

If you look at the heat absorption effect, the Antarctic tube is as good as the heat retention effect.

Antarctic tube He absorbs heat very quickly.
