1 Working principle of wall-mounted solar water heater

The working principle of wall-mounted solar water heater uses a flat plate collector. The flat plate collector can convert solar radiation into heat to increase the temperature in the collector. Taking advantage of the characteristics of low density of warm water and high density of cold water, an underwater heat cycle is formed by circulation. Wall-mounted solar water heaters heat this way. The working fluid in flat headers is usually a low temperature resistant liquid that can generally maintain temperatures below minus 40 degrees Celsius without freezing, so there are not many restrictions on the operating temperature.

2. Is the wall-mounted solar water heater easy to use?

As a sort of newer products have not yet been widely accepted. But the heatersWall-mounted solar water heaters overcome the shortcomings of traditional water heaters and are more competitive in some regions.

1. Advantages

Wall-mounted solar water heaters are anti-freeze, anti-explosion, anti-leakage and anti- limestone. These are things that traditional water heaters cannot do.

1) Antifreeze: Due to the special properties of the liquid contained in the flat collector of the wall-mounted solar water heater, it can operate normally at low temperatures. there is no need to fear being frozen;

2) Anti-explosion: Traditional water heaters may risk bursting at high temperatures, while wall-mounted solar water heaters can withstand high temperatures thanks to to their patented technology;

 3) Leakage prevention: The traditional water heater is connected to the water tank and the vacuum tube. If the tube leaks, all water. The water heater will collapse, while the flat plate heat exchanger allows the water heater to operate in a fully closed manner, so there is no need to worry about water leakage. 4) Anti-scale: if the ice scale on the vacuum tube is very thick; , it will prevent heat from being transferred, but the new solar water heater can realize flat plate heat exchange, that is, waterless operation.

5) In addition, wall-mounted solar water heaters are not limited by the height of the ground, as long as the balcony is exposed to light, installation on the balcony also saves space indoors; .

2. Disadvantages

1) Few manufacturers. The wall-mounted solar water heater is a new product. People don't know much about it and there are very few manufacturers. Purchasing a high-quality wall-mounted solar water heater is not as convenient as purchasing a traditional water heater.

2) The price is high. Because it uses patented technology, the production cost is high and there are few manufacturers, which naturally leads to high prices.

3) The temperature is low. The maximum temperature is lower than traditional solar water heaters.

4) Largely influenced by the outside world. For example, on rainy days or in winter when there is less sunshine, wall-mounted solar power does not have a heat source and often needs to be turned on.

5) There are requirements for the size of the water tank. Because it is hung on the outdoor balcony, considering the load-bearing problem, according to national standards, the water tank volume of the wall-mounted solar water heater cannot exceed 80L.

3. Which brand of wall-mounted solar water heater is the best

Is wall mounted solar water heater easy to use? of life

The principle of wall-mounted solar energy: the solar panel sensor absorbs thermal energy and the conduit circulates hot water in the water storage tank thanks to the hot and cold cycle method

The hot water system uses the fins inside the flat sensor to convert the radiantSolar energy absorbed into thermal energy, causing the temperature of the working fluid in the heat exchange tube of the collector to increase continuously. Hot liquid has low density and cold liquid. Due to its high density, a natural circulation of cold water from top to bottom and hot water from bottom to top is formed between the collector and the water tank. the circulation pipeline.

Thanks to this cycle, the water in the water tank gradually heats up. Since the working fluid in the flat collector is a low temperature resistant liquid, it can be maintained at minus 40 degrees without freezing. So even in alpine and cold areas it can operate normally all year round.

Detailed information

Advantages

1. Save space, the collector is separated from the water storage tank, solving the installation problems of high-rise users;

2.The collector Itcan be hung on the balcony or exterior wall to reduce wind resistance and look beautiful;

3. The collector does not directly contact the water in the pipe, but conducts thermal energy to the condensing end. through the conductive liquid, thermal energy is transferred from the condensing end to the scale-free conduit;

4. The transfer fluid is a professional antifreeze agent and can be used normally in low temperature conditions. heat in two minutes under the sun;

Let's talk about its advantages first

1. Split Installation: The collector portion of the hot water system is completely separate from the water tank. The collector is installed outside (or inside) the balcony. The water tank makes full use of the outdoor space. from the balcony, solving the problem of high-rise buildings.The problem that users cannot install solar water heating systems has been solved, and the perfect combination between solar energy and buildings has been achieved.

2. Operation under pressure: the circula systemWater system is a pressurized system, the water outlet pressure is stable, can reach constant temperature and pressure, and has a strong flushing feeling, making bathing more comfortable. .

3. System energy saving: The working fluid circulation system is natural circulation, so when there is enough sunshine, it can provide hot water to users, but the whole system does not consume any energy.

4. One-way heat exchange: There is no water circulating in the heat exchange tube of the flat plate collector, and the collector and water tank work in a heat exchange manner. And the heat exchange is a one-way heat exchange. Therefore, the heat present in the water tank will not be lost to the outside via the collector.

Secondly, let's talk about its shortcomings

1 The average capacity of wall-mounted solar water heaters cannots be known

Generally, when wall-mounted solar water heaters are installed. Water heaters on balconies work at high temperatures for a long time, the fluid gradually evaporates, the biggest problem for users is that they do not know the fluid capacity and when they need to add or replenish fluid. fluid. Future maintenance of the product will cause a lot of trouble to users.

2. The installation location of the water tank of the wall-mounted solar water heater is limited.

Wall-mounted solar water heaters on the market now generally use natural circulation due to their large size. circulation resistance of natural circulation solar pipeline, the heat and cold exchange speed is slow, and the installation conditions of the pipeline are difficult, so the water tank should be higher than 50cm. If the collector is installed on the balustrade of the ballcon, the water tank must be greater than 50 cm. being hung high on the wall, with a small height difference, etc., resulting in slow and inefficient heat exchange.

3. It is difficult to add antifreeze to wall-mounted solar water heaters

Generally, wall-mounted solar water heaters on balconies use indirect heat exchange, and medium circulation is required for operation for prevent pipes from freezing in cold areas and directly The problem of scale forming easily in the circulation manifold. However, a special filling pump is required to add the fluid. Unscheduled addition and rehydration require professionals to perform a tedious operation.

In today's situation where air and water pollution are common, environmental protection has become a hot topic. What methods can be used to make the mountains green et green waters? As ordinary people, we can only start with the ? little things around us and do our best to live a low carbon life.
