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 
2. Manometer 
3. Pump speed adjust switches 
4. Temperature difference circulation pump 
5. Flow rate indicator 
6. Return circuit connector 
7. Safety valve

Q:What is the classification of solar collectors?
According to the use of hot plate materials are: copper collector plate, copper and aluminum composite collector plate, aluminum collector plate
Q:Vacuum tube for solar collectors
Heat pipe vacuum tube and other types of solar water heaters, compared with the following irreplaceable advantages:
Q:Flat solar collector how, flat solar collector working principle introduced
The installation of the system search should ensure safety and functionality while taking into account the combination with the building.
Q:Is solar collector directly using solar energy?
Solar collectors are directly using solar energy. A solar collector is a device that converts radiant energy from the sun into heat.
Q:The characteristics of flat solar collectors
easy to achieve with the combination of building components. Coupled with its collector plate for the metal material, can be easily used wire, welding and other connections, for the installation, maintenance and use to provide a convenient. Second, has a high thermal efficiency.
Q:Condensation type solar collectors and non-concentrating heaters
Solar collectors can be classified by a variety of methods, for example: according to the type of heat transfer refrigerant, according to enter the mouth of the solar radiation is to change the direction;
Q:How can solar collector system prevent wind?
The collector must be provided with proper wind protection, bolted or secure. Other components of the solar thermal water system are affected by the wind may cause damage or affect the normal operation of the system,
Q:Solar collectors and tank water can not cycle what is the reason
If the exhaust valve is not installed, theoretically through the collector outlet pipe directly discharged to the tank, the water part of the pipeline gas block the possibility is not large.
Q:Flat solar collector is a good blue film, or good black chrome? It is best to specify.
The absorption ratio α and the emission ratio ε of the black chromium coating are 0.93-0.97 and 0.07-0.15, respectively, and α / ε is 6 to 13, and has excellent spectral selectivity.
Q:With the tonnage of solar collectors and air to hot water which power consumption
This question relates to what assistance is to be used in the hot water project of the solar collector, as well as the location and duration of the project. If you do not use auxiliary heating equipment, there is no doubt that the solar collector hot water project power consumption is minimal, but due to the uncertainty of the sun
