Q:Is solar collector directly using solar energy?
As the solar light is more dispersed, we must try to put it together, so the collector is a key part of the use of solar energy devices.
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: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
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:Condensation type solar collectors and non-concentrating heaters
according to whether to track the sun, according to whether there is a vacuum space; According to the collector type of heat transfer, the solar collectors can be divided into two types. Liquid collector air collector according to enter the mouth of the solar radiation is to change the direction of classification According to the solar radiation into the lighting port to change direction,
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: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.
Q:Where is the solar collector installed in the building?
There are flat-plate collectors and vacuum tube collectors, as well as medium-high temperature trough collectors in different forms, the installation site requirements are not the same; but generally according to geographical location, towards the basic south.
Q:Flat solar collector is a good blue film, or good black chrome? It is best to specify.
Black chromium coating thermal stability and high temperature performance is also very good, suitable for high temperature conditions, at 300 ℃ long-term stable operation. In addition, the black chrome coating also has good weather resistance and corrosion resistance.
