Who can talk about the advantages and disadvantages of flat plate solar collector and vacuum tube solar collector?
The advantages and disadvantages of vacuum tube solar collector and flat plate solar collector:
5 different applications in different industries, in effect, all-weather supply of hotel apartment, the thermal efficiency is lower, because they require all-weather supply of hot water, which requires solar panels running in the premise of a relatively high temperature, heat dissipation caused by the larger, used in factories, schools and other places of the hot water supply timing at night will be better in the morning, because cold water can make solar system, low temperature, high temperature operation efficiency is relatively high, but no matter what kind of condition, the heat efficiency of the system is less than 36%.
Plate solar heat collector:Copper aluminum composite anode plate core collector; all red copper selective coating plate core collector; total copper nitrogen titanium oxide coated plate core collector three kinds.Two. Manufacturing method of flat plate solar collector:The heat collector plate core and its manufacturing method of flat plate solar collector, the plate core consists of two pieces of metal sheets stacked together around the seaming process together, made of flat type metal absorber, and insulation galvanized plate at the bottom, the upper glass plate covered with rubber seal around. The bottom of the groove on the light receiving panel is connected with the back plate by stamping to form a transverse and longitudinal mutually connected working fluid passage.
