Introduction of Non-Pressure Solar Water Heater:
Non-pressure Solar Heater is one of the most economical solar water heating device with pretty high efficiency at the same time. It consists of hot water storage tank, solar vacuum tubes with mouth plug in storage tank, and bracket supporting tank and tubes.When cold water in evacuated tubes is heated with solar irradiation, as the specific gravities of hot water and cold water are different, hotter water goes upward to storage tank and colder water goes downward to glass tubes. through this continuous circulation, the cold water in storage tank will be gradually heated till sunset.
Solar water heaters working principle
1. The solar collector absorbs solar energy and transmits it to the solar water heater tank through circulation
2. When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically
3. The circulation pump makes heat-conducting liquid circulate automatically
4. The heat-conducting liquid transfers heat to water by lower heat exchanger in the water tank.
5. When the temperature difference between solar collector and heat pipe solar water heaters tank doesn't reach the set value, the circulation pump will be shut automatically
6. In case the temperature of the water tank does not reach Tmax, Electric Heating Element will start to work automatically
Solar water heaters working station component:
1. Operating screen
3. Pump speed adjust switches
4. Temperature difference circulation pump
5. Flow rate indicator
6. Return circuit connector
7. Safety valve

5.Reduce your water heating costs
- Q:Vacuum tube for solar collectors
- Good insulation: heat pipe has a one-way heat transfer characteristics, so that hot water at night will not heat down the heat pipe to the surrounding environment.
- Q:What is a trough solar collector?
- As a high-temperature collector, can get a higher collector temperature, can be used for power generation, refrigeration and air conditioning, heating, desalination and other production and living areas.
- Q:Where is the solar collector installed in the building?
- Different local requirements and horizontal angle is not the same, in the north and the horizontal angle needs a little bigger.
- Q:What is the solar collector
- Because of the different use, the collector and its matching system type is divided into many kinds, the name is also different, such as cooking for the solar cooker, used to generate hot water solar water heater, dry items for the solar dryer, for Melting metal solar furnace, as well as solar houses, solar thermal power plants, solar desalination and so on.
- Q:Is solar collector directly using solar energy?
- Most of the solar water heaters are equipped with electric auxiliary heating function, when the rainy weather will automatically start when the electric heating function.
- Q:Flat solar collector how, flat solar collector working principle introduced
- Non-structural force components such as lightweight fill walls shall not be provided with heaters. 2) in the need to do waterproof parts, shall not damage the waterproof layer. 3) The use of bracket installation, should be in accordance with the requirements of the design drawings to check the strength, durability, and the building of the fixed way.
- Q:Flat solar collector is a good blue film, or good black chrome? It is best to specify.
- Black chromium coating thermal stability and high temperature performance is also very good, suitable for high temperature conditions, at 300 ℃ long-term stable operation. In addition, the black chrome coating also has good weather resistance and corrosion resistance.
- Q:What is the working principle of flat solar collectors?
- Flat plate solar collector heat plate is flat shape, hence the name. It consists of transparent cover, heat sink, and jacket composed of four parts. The solar radiation passes through the transparent cover of the collector, is projected on the heat absorbing plate, the heat absorbing plate absorbs and converts it into heat energy, and then the heat is transferred to the heat transfer medium in the heat absorbing plate to raise the temperature Useful energy output.
- Q:What is the classification of solar collectors?
- According to the collector heat transfer type: liquid collector, air collector. According to whether the solar radiation into the lighting port to change the direction of points: condenser type collector, non-concentrating type collector.
- Q:With the tonnage of solar collectors and air to hot water which power consumption
- work efficiently, like the four seasons Mu song launched ultra-low temperature air, at -25 ℃ efficiency will be able to work; the north of the Yellow River, solar collectors hot water project power consumption The amount is smaller.
