Product Description:

Solar Water Heater

1.Warm place available

2.the most competive price

3.Beautiful design

4.Best service and high quality

 

Working principle:

High quality vacuum tubes absorb sunshine and heat cold water in the vacuum tubes. According to the density difference of cold and hot water, when absorbing sunshine, cold water in vacuum tubes turning to hot water rises to tank, meanwhile, cold water in tank sinks to vacuum tubes. That is the circulation in this type of solar water heater. The whole system is always circulating continuously.

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:The introduction of flat solar water heater
Flat solar collectors placed in the building bar inside the balcony, windows, roof, walls, make up for the traditional solar water heater due to lack of congenital can not achieve the perfect combination with the building and the environment regret.
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:What is a trough solar collector?
The traditional trough solar collector device adopts the vacuum glass tube structure, that is, the inner tube adopts the metal tube, the tube takes the heating medium, the metal tube is coated with the selective absorbing coating, and then the outside is the glass tube, the glass tube and the metal pipe Vacuum to suppress convection and conduction heat loss.
Q:The characteristics of flat solar collectors
Therefore, in the same lighting area and daylight intensity, flat solar water heater daily average efficiency is generally higher than the vacuum tube solar water heater daily average efficiency of more than 6%. Three is a good pressure performance.
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:How can solar collector system prevent wind?
should be added appropriate protective measures. Solar hot water engineering system installed in the outdoor part should be able to withstand not less than 10 wind load; if the local history of the maximum wind
Q:Solar collectors and tank water can not cycle what is the reason
air block, including the pump inside the air, and the pipeline part of the air two cases. The pump has a bleed screw, open the deflated and then screw on it, if the pipeline is air block, the general solar energy is installed during the pre-set the exhaust valve, check the exhaust valve is not blocked.
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: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
