How to solve the problem that solar energy is not strong due to age

For vacuum tube solar water heaters, it is necessary to check the vacuum degree of the vacuum tube or whether the inner glass tube is broken, when the barium - titanium getter of the vacuum tube turns black, it indicates that the vacuum degree has decreased, and the collector tube needs to be replaced. Cleaning should be done early in the morning or late afternoon when the sun is not strong and the temperature is low to prevent damage to the parts. How to use vacuum tube cleaning descaler:

1. Open the water inlet of the solar water heater; It is safe and harmless to stainless steel, copper and glass, etc. 3. Automatic thermal cycle for 20-30 minutes, so that the descaler solution fully contacts all parts; 4. Open the drain and drain the cleaning liquid; Prepare scale, minerals and alkaline residues on the inside and its surface, 5. Fill the water tank with water and then circulate it for two minutes; 6. Drain the circulating water, and complete the cleaning and descaling work. Tips: 1. The structure of different solar water heaters is different, please adjust the use method according to the manual (it is recommended to be operated by a professional maintenance person).

2. Heat the water to about 40 degrees to descale, the effect is better.

I'm a professional. I don't know if you can accept it, dilute the hydrochloric acid with water, pour it in, wash the tube with water after ten minutes, apply the dish soap at the top of the tube and install it gently. If there is a dripping phenomenon around the tube, you have to just change the rubber band, and the solar shop has accessories.

It's simple.

Give your solar collector tube, clean it and it will have a good effect! Do him to check whether the insulation material has been sexual,。。

Replace the solar tube, because after a long time, there is limescale in it, which affects the heat collection.

What type of solar energy are you? What a brand!

Yours is solar or something!!

1. If the water pressure of tap water is unstable and the phenomenon of sudden cold and heat, if this situation is not very serious, you can buy a thermostatic water valve to solve it, if the tap water pressure is unstable or too low, you should consider buying a booster water pump to solve it;

2. The connecting hose on the sprinkler head is aging, expanding and twisting, and the internal water flow of the water pipe is blocked, so the connecting hose should be replaced with a new one.

What brand, is it that the solenoid valve has a manual water supply and is not turned off?

You're in too much of a hurry, and the range of adjustment is too large, so you have to adjust it a little less.

Add pipeline booster pump, hot water pump, but also depending on the distance between the two, how much the pump head will be, preferably more than four or five meters, the best imported German and other European pumps.

It could be that there is a problem with your mixing switch. Or mixed up from elsewhere.

You can use a hybrid type of solar and electric heat, and this problem is solved.

You can press the vacuum pump, and after using up, the water pipeline will be pumped into a vacuum, and there will be no residual water in the pipeline when you take a bath, and what will be released is hot water.

It is possible to connect a solar water heater in series with a gas water heater. The temperature of the water under solar energy is below 45 degrees. (This temperature can be customized) starts the gas water heater and raises the water temperature to a temperature that can be used for bathing.

The temperature of the water below reaches 50 degrees. The gas water heater will automatically turn off or not start. This process is carried out by an automatic temperature control switch.

With this change, it saves both water and time.

Simple, you can add a small pipe circulation pump between the hot water pipe and the water pipe (the power is very small and very cheap), and before you use the hot water, just turn on the circulation pump for a while.

The only way to completely solve the problem is to install another storage electric water heater, and use the solar water heater as a supplement. "But the roof is still 4 floors high from my floor" In this case, it is not suitable to install solar energy, so on the whole, do not choose solar energy.

The current design can be done in the style of a hotel, and there is hot water when it is turned on.

You have just started to decorate now, and the waterway arrangement should have one more circuit, remember!

As for the products, you can check them out.

In addition to the normal circulating system is basically unchanged, the pressure of the collector box and the collector tube is no problem, and the focus is on the bottom bracket of the collector box system to be fixed. With this little bit of pressure, almost any pipe can withstand.

If you install an exhaust port, it should be higher than the top of the water tank, and you can also install the exhaust port without it.

Hello, is this situation you are talking about a reality or do you imagine it! The temperature of the water tank is stable above the top of the collector, and the control system can be used to make a fuss and the system is circulated. It also depends on whether the water tank is heated by auxiliary heating, or whether it occurs early in the morning or in the evening, and you need to carefully analyze your water situation.

The water tank is no problem than the collector, the vacuum tube module is basically not pressurized, the first attention is paid to the equal range principle in pipeline design, and the second attention is paid to the selection of pipelines and circulating pumps; Third, pay attention to the installation of senior executives, etc. I wish you a speedy solution! FYI.

My technical solution to be sent to your inbox.

Yes, through the infrared, it can reflect visible light, but the heat collection effect will be worse.

Water heater reflector is installed around the vacuum heat pipe, the reflector is made of glass mirror, the reflective coating of the glass mirror has a layer of spraying plastic, to protect the reflective coating from moisture, sunlight is reflected to the vacuum heat pipe through the reflector, the vacuum heat pipe can absorb more sunlight, so that the water temperature is greatly increased, and the defect of low water temperature in cold weather is solved.

The answer is: "Yes"!!

We know that sunlight is composite light, and if we only absorb a few monochromatic lights in the composite light, such as absorbing red light, and all other lights are reflected, isn't it okay?

Roar

Solar water heaters are vacuum tubes and transparent.

Because the vacuum tube can lock in the heat very well. To reflect the light strongly, simply attach a mirror under the vacuum tube, because it is impossible for the light energy to be completely absorbed by the water. However, this does not seem to work, and only increases optical pollution.

The infrared part of the solar energy is heated, and the general water heater can absorb about 93% of the infrared light. The part of visible light with a wavelength of 380nm-780nm can be reflected by speculars. When you look at a water heater, it is particularly bright at a certain angle because of the specular reflection on the surface of the material.

One is light energy and the other is heat energy, which of course does not affect.

For example, a black mirror absorbs heat energy, but the mirror reflects light energy.

Think about it! Haha pure physics, no chemical stuff!

There is a reflector under the collector tube of the solar water heater, which can reflect light. The reflection is not strong,

There is no such possibility.

Solar energy is converted from the light energy of the sun's rays, and the more sunlight absorbs, the more it converts; If you reflect all the sunlight, there's nothing you can convert.

2+2=4, if you want one of them to become 3, then the other can only have 1, energy conservation.

This is not possible, according to the conservation of energy, when the energy of sunlight reaches the collector pipe of the solar water heater, part of the energy is reflected, and the rest is converted into heat energy to heat the water. The sum of these two parts of energy is equal to the total energy of sunlight reaching the collector tube of the water heater.

The black mirror is so funny, and the black color is precisely because it can't reflect light!

LZ's thinking is wrong, energy is conserved, light energy is also energy, and those that can reflect strongly cannot absorb much heat.

No, it's the same principle that the sun shines on you and you feel warm.
