Split type solar water heaters have the characteristics of efficient heating, sufficient water volume, multi-point water supply, energy saving and safety. Compared to integrated solar water heaters, split-type solar water heaters are more comprehensive. functions, but their installation technology is also more technical.
Characteristics of split-type solar water heaters
Diversified installation methods. Split solar power can be installed on balconies, walls, sloping roofs, etc., which solves the problem that solar water heaters cannot be installed on high-rise buildings. It can also be used by users outside of the upper floors, which increases significantly. the extent of solar energy use.
The shape of the tablet is beautiful and elegant. Split solar energy usess flat sensors and its streamlined design is more beautiful, like a smart skylight, it becomes a beautiful landscape on the roof and achieves perfect building integration.
The water tank has a large capacity. The collector and water tank of the split water heater are separated, which greatly increases the capacity of the solar water heater. Rooftop split solar water tanks usually have various specifications such as 150 to 500 liters.
Automatic water supply and constant water temperature. The split solar water heater adopts pressurized design to realize automatic water supply and ensure that the water tank is always in a flooded state. The cold and hot water pressures are always balanced to meet the needs of the whole family at the same time and completely solve the problem of high and low water temperatures.
What about the water heaterpressure olar? What are the advantages and disadvantages of solar pressure water heater?
The differences between solar pressure water heaters? The solar water heater and non-pressure type are as follows：
The full name of the pressurized water heater is phase change thermal conductivity fully pressurized solar water heater. The phase change thermal conductivity collector tube it uses is. composed of vacuum tube, phase change heat pipe and aluminum heat transfer wing. Because there is a threaded connection between the phase change heat pipe and the water tank, and there is no liquid in the vacuum tube, it can withstand the pressure. Under sunlight, the selective absorption coating transfers the collected heat to the phase change heat pipe through the heat transfer aluminum wings. The heat transfer fluid in the heat pipePhase generation uses two phase change processes to transfer heat to the water in the water tank. , complete the heat exchange. Pressure water heaters are used to push water under pressure (the pressure is basically the same as the water pressure in the local pipe network), i.e. the hot water in the water tank is expelled according to the water pressure. When using, make sure the water supply tap is always open and the water is not turned off. Since the heat pipe and the water tank are connected by threads, there is a risk of water leakage. However, there is no water in the vacuum tube, so there is no possibility of one tube being damaged and the entire can of water leaking out.
Pressureless water heater is called direct plug-in all-glass vacuum tube solar water heater. Since the vacuum collector tube and e tankau are sealed by rubber sealing ring, they cannot withstand pressure. . Non-pressure water heaters are used when they fall into water without pressure, that is, relying on the fall to release the water into the water tank. The main pipelines in the lower part of the water tank are the inlet/outlet pipe and the overflow pipe: when the water tank is full, the overflow alarms from the overflow pipe and the valve water supply are turned off when in use, hot water is supplied; flows from the inlet/outlet pipe under the action of gravity depending on the height difference, the overflow pipe then plays the role of air supply. Since there is water in the vacuum tubes of non-pressurized water heaters, if a tube is damaged, the water in the tank will all flow out. However, “Shaile” brand all-glass vacuum collector tubes are made of glassre with high borosilicate content, so the risk of damage from natural disasters is extremely low.
Supplement: Pressure-bearing type is subdivided into two types: full-pressure-bearing type and full-pressure-bearing type means that the collector and water tank are fully closed and that the system works. under pressure. The pressure depends on the water supply pressure of the local municipality. Another type of collector is open to the atmosphere, while the water tank is pressurized.
When both types of solar water heaters use water, the cold water flows countercurrent to the hot water, which is similar to the water outlet of the heater electric water. The water supply flow rate is large and comfortable for washing. . But once the water temperature increases (the boiling point of water increases with pressure), the reducerpressure (safety valve) is the key! Because hot steam can push the train and it's so powerful! At present, in the solar thermal energy utilization industry, under the conditions of relying on the sky to collect heat, there is no fear of overheating or overheating. Many products lack humanistic design! Unpressurized means the entire system is open and connected to the atmosphere, and the water temperature will not exceed 100 degrees! (When the sun is good, you can boil the pot.) The hot water pressure depends on the height of the installation. It is only 0.98 kilograms at a height of 10 meters! My value is that the hot water pressure should reach 1 kg to be comfortable.
Of course, different people will have different feelings. In another aspect, this Chinese style solar water heater forms a water supply situation.dual-channel water once the pressure of municipal water supply changes (architectural water supply and drainage majors call it intensive water supply, because the fluctuation of water pressure causes bath water). becomes hot and cold), shit The basin is buckled on the head of the solar water heater! Especially in summer and autumn, when the sun is sufficient, the safety and comfort of the all-glass vacuum collector tube directly inserted into the falling water solar water heater is greatly reduced, so that the thermostatic valve or faucet corresponding thermostat reflects the level of humanism of the manufacturer. consumer concern. Of course, the correct assortment of thermostatic faucets has not yet become a trend among solar manufacturers.
When choosing a solar water heater, you should choose a heater water under pressure. BecauseThe pressurized water outlet is stable, it will not become hot or cold. Secondly, it is recommended to choose a hot plate water heater based on the pressure type. Since the heat collector plate water heater is split type, the pressure water tank can be placed inside. There is no need to install it on the roof as a whole like a vacuum tube water heater, which not only solves the problem of roof pressure, but also ensures the problem of tank insulation of water. Third, the pressurized water tank of the selected solar water heater must have an enamel inner tank. The enamel inner tank has good anti-corrosion effect, strong pressure and long service life. As long as it meets the above three points, it is basically a high thermal efficiency solar water heater. Of course, based on this, try to use platess heat collectors and imported anti-freeze media. Although its price is a little higher, it has high thermal efficiency and a long lifespan. Many foreign brands of domestic solar water heaters are counterfeit. They are assembled from parts purchased domestically and sold under the import name. Most genuine imported products come with English installation instructions, and each interface of the machine has English labels, which can be distinguished with a little attention.

2. What are the advantages and disadvantages of pressurized solar water heaters?
(1) Advantages of pressurized solar water heaters< /strong> p>
The superconducting heat pipe of the so water heaterThe pressurized air transfers heat in one direction. Due to its low thermal capacity, its starting temperature is relatively low, so the temperature rises quickly. resistance to low temperatures. It will not freeze even in a very low temperature environment.
The inner tank of the pressure water tank uses high-frequency welding, which can be directly connected to the tap water system and can work automatically.
Water will not leak inside the vacuum tube of the pressurized solar water heater, which greatly improves the thermal efficiency of the product, and the vacuum tube will not be frozen or cracked in cold weather.
Even if only one pipe of a pressurized solar water heater is broken, the water heater can still operate normally.
The solar pressure water heater is fully automatic pressure operation, which is conveniente.
(2) Disadvantages of solar pressure water heaters
Since the pressure water heater has a relatively large area when installed, it has a certain cooling effect. thermal insulation on the floor.
Since the hot water pipe of the pressure water heater is long, a lot of water is wasted with each use.
A pressurized water heater must be exposed to the sun all day to heat the water, so it cannot guarantee that hot water will be available at all times, and the comfort level at this regard is relatively weak.
The solar pressurized water heater lighting panel should be installed in the house. However, if it is installed on the roof, it will affect the overall aesthetics of the building. If it is in a relatively upscale residential area, this will be more obvious over time, it could damage the waterproof layer of the roof.
Concerning the nature ofe photoelectric complementarity, in fact, pressurized solar water heaters are not yet fully realized.
What are the advantages and disadvantages of pressurized solar water heaters and what are the advantages and disadvantages of pressurized solar water heaters Have you seen it? As the saying goes, there are pros and cons, so don't you do it? Don't be too careful when buying. Pressure is fine as long as you like it.
What is solar energy? Built-in type and split type
First of all, when choosing a solar water heater, you should choose a pressurized water heater. Because the pressurized water outlet is stable, it will not become hot or cold. Secondly, it is recommended to choose a hot plate water heater based on the pressure type. Since the heat collecting plate water heater is split type, the water tank underpressure can be placed inside. There is no need to install it on the roof as a whole like a vacuum tube water heater, which not only solves the problem of roof pressure, but also ensures the problem of tank insulation of water. Third, the pressurized water tank of the selected solar water heater must have an enamel inner tank. The enamel inner tank has good anti-corrosion effect, strong pressure and long service life. As long as it meets the above three points, it is basically a high thermal efficiency solar water heater. Of course, based on this, try to use imported heat collecting plates and anti-freeze media. Although its price is a little higher, it has high thermal efficiency and a long lifespan. Many foreign brands of domestic solar water heaters are counterfeit. They are assembled fromof parts purchased domestically and sold under the import name. Most genuine imported products come with English installation instructions, and each interface of the machine has English labels, which can be distinguished with a little attention. So there is no need to pay too much attention to the brand. Of course, it is best to have after-sales service commitments.
Integrated solar power is solar power in which the water tank and collector are connected together. Domestic integrated solar power is solar power integrated with multiple vacuum tubes. The vacuum tube is directly inserted into the water tank. . It does not support pressure and is relatively inexpensive.
Of course, there are also pressure-integrated and flat panel solar products, but they are relatively rare and are unconventional products.
Split solar means the water tank and collector are separate. Household split solar is generally divided into wall-mounted balcony and 80-120 liter wall-mounted balcony. smaller capacity. Rooftop split solar panels are generally available in sizes ranging from 150 to 500 liters. Split solar panels are primarily pressure resistant, with more flat panels and some manufacturers producing vacuum tubes. Split solar panels are more expensive, and the price of split solar panels with the same volume is 3-6 times that of integrated solar panels.
