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:Vacuum tube for solar collectors
Heat pipe vacuum tube and other types of solar water heaters, compared with the following irreplaceable advantages:
Q:Solar collectors and tank water can not cycle what is the reason
pipeline loop problem. If there are other piping behind the pump, pay attention to other pipeline valve opening and closing situation
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: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:The introduction of flat solar water heater
In this paper, the use of some technical terms and parameters to cover the flat and heat pipe type solar water heater between the essential differences; unprovoked flat-type solar water heater advantage, malicious belittle and negative heat pump solar water heater.
Q:Superconducting heat pipe solar collector temperature ok
Heat pipe collector can be used under the conditions of minus 50 ℃, can withstand pressure operation, but the heat pipe condensation side (heating side) surface area is only one hundred percent of the vacuum tube, easy to scale, heat transfer effect as vacuum tube, and the use of direct effect By the heat pipe itself, the quality and life of the impact of some heat pipe quality decline and attenuation problems,
Q:Flat solar collector how, flat solar collector working principle introduced
Set up reliable lightning protection measures. 5) The storage tank base must be located on the load-bearing wall (beam) of the building and reserved for fixing parts. The gap between the embedded part and the base, the application of fine stone concrete filling dense. 6) storage tank application anchor bolts and foundation connection firmly.
Q:About centralized solar water heater
passes through the solenoid valve or the collecting system circulating water pump under the control of the control system to run automatically, The hot water in the collector will be transferred to the
Q:What is the classification of solar collectors?
According to the collector temperature range is divided into: low temperature collector, the temperature collector, high temperature 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.
