*Solar Keymark , EN****5 , CE, , SRCC *Quality Assurance: European Standard *We are Manufactory, OEM project are welcomed Flat Plate Collectors In thermal processes, flat plate collectors intercept solar radiation on an absorber plate in which passages for so-called carrier fluid are integral or to which they are attached. The carrier fluid (liquid or air) passing through these flow channels has its temperature increased by heat transfer from the absorber plate. The energy transferred to the carrier fluid, when divided by the solar energy incident on the collector and expressed as a percentage, is called the instantaneous collector efficiency. Flat plate collectors generally have one or more optically transparent cover plates intended to minimize heat losses from the absorber plate, in an effort to achieve maximum efficiency. Typically, they are capable of heating carrier fluids up to *2° C (**0° F) with efficiencies between *0 and *0 percent. Solar Heating Flate plate collectors utilize the sun&#**9;s energy to warm a carrier fluid, which in turn provides usable heat to a household. The carrier fluid, which in this case is water, flows through copper tubing in the solar collector, and in the process absorbs some of the sun&#**9;s energy. Next, the carrier fluid moves to the heat exchange, where the carrier fluid warms water that is used by the household. Finally, a pump moves the carrier fluid back to the solar collector to repeat the cycle. Flat plate collectors have been used efficiently for water and comfort heating. Typical residential applications employ roof-mounted, fixed collectors. In the northern hemisphere, they are oriented in a southerly direction; in the southern hemisphere, they are oriented to face north. The optimum angle at which to mount collectors relative to the horizontal plane depends on the latitude of the installation. Generally, for year-round applications such as providing hot water, collectors are tilted (relative to the horizontal plane) at an angle equal to the latitude angle ± *5°, and are oriented to face true south (or north) within ± *0°. In addition to the flat plate collectors, typical hot-water and comfort heating systems include circulating pumps, temperature sensors, automatic controllers to activate the circulating pump, and a storage device. Either air or a liquid (water or a water-antifreeze mixture) can be used as the fluid in the solar heating system, and a rock bed or a well-insulated water storage tank typically serves as an energy storage medium.
