There are now many options for installing water pipes for solar water heaters, such as water pipes
PPR
, copper pipes , copper-plastic pipes (aluminum-plastic pipes). , and PVC
Pipes, iron pipes, etc.
In fact, considering various factors, PPR water pipes are quite ideal.
The reason is also very simple. First of all, it's a good PPR. The quality of water pipes is very reliable and can be compared with copper pipes and the price is simpler; to accept and inferior to copper pipes; and the important thing is that it is healthy and free from any rust and patina.
Note that the water line must be
6
split.
PPR
Water pipes are divided into cold water pipes and hot water pipes. The key is the thickness of the pipe wall. It is recommended that everyone use water pipeswarm for drainage. at home. The pipe wall is thicker, the quality is better, and the price is not much more expensive.
What are the general specifications of Huangming solar tubes?
There are many types, including 47 tube, 58 tube and 70 tube. The lengths are 1.5 meters, 1.6 meters, 1.8 meters, 1.92 meters and 2 meters 2.1 meters. The process is divided into gradual color coating. and a multi-chamber layered coating. If you want, Maimai Solar recommends visiting the local Temple Solar store to take a look. Top brands of solar energy companies with more than 20 years of history are trustworthy. for you. If you don't know how to choose a product with excellent quality and precautions, please contact us Are there any types of solar water heaters that do not store water in the tubes absorbing heat?
Specificationsons of Huangming solar tubes:
Three tubes: ? The length is 1.8 meters, the outer diameter is 5.8 cm, and the inner diameter is 3.7 cm.
Super cold polar tube: length 1.9 meters, outer diameter 5.8 cm, inner diameter 4.7 cm.
Light cube tube: length 2.1 meters, outer diameter 8.4 cm, inner diameter 3.7 cm.
Advantages of solar energy:
(1) Universal: The sun shines on the earth and has no geographical restrictions. It can be found everywhere, regardless of land or sea, mountains or islands. , and can be directly The development and use is easy to collect and does not require mining and transportation.
(2) Harmless: The development and use of solar energy will not pollute the environment. It is one of the cleanest sources of energy, which is extremely valuable today as environmental pollutionment is becoming more and more serious.
(3) Huge: The energy of solar radiation that reaches the Earth's surface each year is approximately equivalent to 130,000 billion tons of coal, and its total amount constitutes the greatest energy that can be developed in the world today.
(4) Long term: Based on estimates of the rate of nuclear energy produced by the sun, hydrogen storage is sufficient to last tens of billions of years, and the duration life of the Earth is also about billions of years. In this sense, we can say that the energy of the sun is inexhaustible.
Disadvantages of solar energy:
(1) Dispersion: Although the total amount of solar radiation reaching the Earth's surface is large, it canThe flow density is very weak. On average, near the Tropic of Cancer, when the weather is relatively clear in summer, the irradiance of solar radiation is maximum atnoon, and the average solar energy received over an area of 1 square meter perpendicular to the direction of sunlight is about 1,000 W if the average day and night throughout the year is only about 200 W. In winter it is only about half, and on cloudy days it is usually only about 1/5. This energy flow density is very low. Therefore, when using solar energy, if we want to obtain a certain conversion power, we often need a set of collection and conversion equipment with a considerable area, which is expensive.
(2) Instability: due to the limitations of natural conditions such as day and night, season, geographic latitude and altitude, as well as the influence of random factors such as clear , cloudy, cloudy, rain, etc., reaching a certain ground Solar irradiation is both intermittent and extremely unstable, makingmore difficult the large-scale application of solar energy. In order to make solar energy a continuous and stable energy source and ultimately become an alternative energy source that can compete with conventional energy sources, the problem of energy storage must be well solved , that is, the energy of solar radiation during clear days should be stored as much as possible for use at night or when it rains. It is used for everyday use, but energy storage is also one of the weakest links in solar energy use.
(3) Low efficiency and high cost: The level of development of solar energy utilization is theoretically feasible in some aspects and technically mature. However, some solar energy utilization devices have low efficiency and high cost, and the current laboratory use efficiency only exceedsnot 30%. In general, the economy cannot compete with conventional energy. For a considerable period, the future development of the use of solar energy will be limited mainly by economic reasons.
(4) Solar panel pollution: At this stage, solar panels have a certain lifespan. Typically, they need to be replaced every 3 to 5 years at most, and replaced solar panels are very difficult to replace. polluted by nature decompose, causing considerable pollution.
Yes, solar heat absorbing tubes are generally divided into two types, namely single vacuum tubes and double vacuum tubes, but there is water in them. vacuum tubes, which are more commonly used in the south. and the price is relatively high. It will be lower. Double vacuum tubes are also called vacuum superducts. Heating is done by evaporation of the medium in the tubes.empty. vacuum tubes. The advantage is that this won't be the case. When the water freezes and expands, it will burst the pipe, but the price will be a little more expensive! I hope this helps you!
