Integrated non-pressure solar water heater
Integrated compact pressurized solar water heater
Compact pressurized solar water heater with copper coil (pre-heated solar water heater)
pure and drinkable. 2) Insulation layer of water tanks adopts polyurethane foam, thickness in 55mm 3) The tubes and frame are adjustable, power bearing is average, and can assure the vacuum tubes to use long time.
Whole glass vacuum tubes adopt super hard borax and silica glass
4) Absorb rate: : 93% � thermal radiation rate: 6%.Resist 25mm hail, using life can last 15 years.
5) Temperature when exposed to sun without water can reach 250: ,2.5hours to boiling if using single tube lf you use electrical appliances to aid heating, to switch off the power supple before bathing. To test the water temperature before using, in order to avoid scalding.
Introduction: Thermo siphon solar collectors provides mains pressure pre-heating via a high efficiency copper coil heat exchanger located within the solar collector tank. The way in which the Mains Pressure solar collector heats water is the same as the Non pressure solar collector. Rather than using the water in the tank directly, as the Non pressure does, the type uses a 45-60 meter copper coil heat exchanger inside the tank which provides more than 1.2m2 of heat transfer area. When water flows though the coil it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore a thermal store. One advantage of this system is that almost no water is introduced into the tank (apart from occasional topping up),so corrosion and scale buildup are almost totally eliminated. Tanks are designed for low to medium pressure applications using gravity feed tank or pressure reduction valve. Direct connection to mains pressure water supply is not permitted. Please check your local building/plumbing regulations regarding the installation of water tanks.
Performance Data Conversion Factor: ho=0.717 Loss Coefficients:a1=1.52,a2=0.0085
Features:� �1. The collector and the water tank are separated, and the system runs under the forced pressure. 2. The controlling device is specialized, so the system runs automatically. 3. The water tank can be installed anywhere. 4. The heat pipe vacuum tube collector is two circuit system, free of freezing and could be used all year. 5. The metal super-- conducting vacuum heat collector is used, no water in the tube, no bursting and could be used as usual under minus 50 6. The water tank applies with the enamel internal bladder, runs under pressure. 7. Provide the water at the same temperature, set the highest temperature, heat the water at set point by electricity, protecting the data when power off, supply the hot water 24 hours a day. 8. The system is designed separately, in harmony with the structure. 9. The heat collector could be mounted on the balcony veranda, the southern wall, sloping roof or awning. 10. The system is designed as unit, convenient to transport.
FTSL-01 FTSL-02 FTSL-03 (NO COIL IN TANK) (SINGLE COIL IN TANK) (DOUBLE COILS IN TANK)
The system comprises of high pressure solar collectors, pressured water tank, heat exchanger or not, a controller, an expansion tank and pumps.
Working principle �
This split solar water heating system has solar collectors on roof and water tanks inside the house, and transfers heat energy collected by the collectors into the tank by natural or forced circulation of the working fluid between collector and the tank.
Functions �
1. Constant temperature circulation: adopt the auto. circulation system to realize constant temperature of the water inside the solar system; Ex-factory default is to ensure the constant temperature of water inside the system and pipelines.
2. Overheat protection: It includes protection of solar collector and electric booster. The former will be operated by the controller automatically to ensure the safety of the solar collector and the solar heat storage system; the later will be controlled by the temperature sensor automatically, to make sure the booster work in a safe condition. Take manual operation to resume to the working condition. 3. Pressure limitation: It functions by automatically sensing the pressure and temperature of the parts, so as to ensure the normal operation of the system. 4. Anti-freezing: It is realized through the circulation of the working fluid to make sure the safety of the operation at the limited temperature.
Features: 1. The solar collector is separated with the water tank, so the water tank can be located anywhere; 2. Solar collector can be mounted on buildings in different styles; 3. Heat pipe solar collector with anti-freezing fluid inside the tubes will achieve high anti freezing effect; 4. Intelligent control system is reliable and convenient; 5. Pressurized operation will guarantee sufficient water flow; 6. Solar water heating system can be connected with auxiliary heating system at the preset joint. This split solar water heating system is a desirable domestic hot water system.
This solar tube adopt international advanced interferometer coating technique. Absorbing layer is coated with Stainless Steel and Nitrided Aluminum. That effectively solved the problem such as performance attenuation of normal vacuum tube under high temperature for a long time
Three target vacuum tube Parameter Ф47 X 1500mm Ф58X1800mm
Features: 1) The tube structure is between all-glass evacuated tube and metal-glass evacuated tube with heat pipes 2) Suitable for frigid zones because there is no water in the tube 3) Designed for pressure system 4) Heat pipe material: TP2 copper 5) The heat collecting part is a vacuum glass tube that lowers heat loss
6) Stable solar conversion throughout the day, with the round shaped tube allowing solar Heat pipe tube
