PHNIX flat plate solar thermal collectors with Germany absorber

 

 

It consists of

  • Flat-plate copper absorber of solar energy :  Germany eta plus-Cu

  • Absorber coating :  Highly selective vacuum coating 

  • Heat transfer medium :  Polypropylene glycol/water mixture

  • Insulating layer : Glass wool with great thermostability 

  • Heat transfer medium tube :  Copper tube

  • Outer casing :  Aluminum alloy

How does flat plate solar thermal collectors work?

Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing solar energy into heat energy. The heat is transferred to liquid passing through pipes attached to the absorber plate.

 

Absorber plates are commonly painted with "selective coatings," which absorb and retain heat better than ordinary black paint. Absorber plates are usually made of metal—typically copper or aluminum—because the metal is a good heat conductor. Copper is more expensive, but is a better conductor and less prone to corrosion than aluminum. And our flat plate solar thermal collectors are made of high performance copper absorber.

 

In locations with average available solar energy, flat plate collectors are sized approximately one-half- to one-square foot per gallon of one-day's hot water use.

 

Applications

The main use of this technology is in residential buildings where the demand for hot water has a large impact on energy bills. This generally means a situation with a large family, or a situation in which the hot water demand is excessive due to frequent laundry washing. Commercial applications include laundromats, car washes, military laundry facilities and eating establishments. The technology can also be used for space heating if the building is located off-grid or if utility power is subject to frequent outages. Solar water heating systems are most likely to be cost effective for facilities with water heating systems that are expensive to operate, or with operations such as laundries or kitchens that require large quantities of hot water.

 

Unglazed liquid collectors are commonly used to heat water for swimming pools. Because these collectors need not withstand high temperatures, they can use less expensive materials such as plastic or rubber. They also do not require freeze-proofing because swimming pools are generally used only in warm weather or can be drained easily during cold weather.

 

While solar collectors are most cost-effective in sunny, temperate areas, they can be cost effective virtually anywhere in the country so should be considered.

Q:Superconducting heat pipe solar collector temperature ok
By the heat pipe itself, the quality and life of the impact of some heat pipe quality degradation and attenuation problems, not easy to be found, and the cost is high, superconducting heat pipe.
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:The characteristics of flat solar collectors
Flat solar water heater advantages: First, particularly suitable for integration with the building requirements. Flat solar water heater because of its structural characteristics of the plane, in the integration of solar energy applications, the shape of flexible structure, the design is not subject to the shape or size of the constraints,
Q:Solar collectors and tank water can not cycle what is the reason
Pipe clogged. If the exclusion of the other two cases, then the possibility of a large pipe block, including the pipeline frozen, debris blockage are possible, if the pump is easier to burn the pump, need special attention.
Q:With the tonnage of solar collectors and air to hot water which power consumption
resulting in no hot water in the rain and snow weather; and air to hot water works relative It is not affected by the sunshine, theoretically can be used throughout the year.
Q:About centralized solar water heater
The solar tube in the solar collector absorbs the solar radiation energy, converts the solar radiation energy into heat energy to heat the water in the collector, the heated high temperature water
Q:Condensation type solar collectors and non-concentrating heaters
solar collectors can be divided into two types. Condenser collector A condenser is a solar collector that uses a reflector, a lens, or other optics to change the direction of solar radiation entering the lighting port and converge to the heat absorber
Q:What is the solar collector
different substances and different colors for different wavelengths of light absorption and reflection ability is not the same. Black color absorbs the sun the strongest, so the cotton is generally used dark or black cloth. White sunshine the strongest ability, so the summer shirt is mostly light or white.
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: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.
