The panel solar geyser collector consists of absorber electric circulating pump electric circulating pump, transparent cover plate, thermal barrier as well as shell. And the solar geysers that are equipped with the panel solar geyser collectors are panel solar geysers, which are mainly the non-pressure water heater. In the middle of the working of the panel solar geyser collector, the solar radiation passes through the transparent cover plate and projects on the absorber plate, absorbed and transformed into heat energy and then deliver to the heat transfer working medium inside of the absorber plate to warm the heat transfer working medium, and then export as the useful energy of the panel solar geyser collector. At the same time, the absorber plate with high temperature is bound to dissipate heat in the way of conducting, convecting as well as radiating, which is the heat loss of the collector.
The panel solar geyser collector is an ordinary style of the vacuum tubes solar geysersvacuum tubes solar geysers collector. It has the advantage of simple structure, reliable running, favorable cost, strong pressure bearing ability as well as large heat absorption area. It is the one of the ideal choice of the connection of the solar energy heater and the buildings.
According to the statistics, the panel vacuum tube solar geyservacuum tube solar geyser has the largest market share in advanced countries in Europe. And in China, the most popular collector is the evacuated tube collector. The popularity of the panel solar geyser collector in foreign countries is due to the different design idea. Generally, the foreign system of the panel solar geyser collector uses indirect system, split system as well as closed pressure bearing system. These systems has high initial cost, but it is reliable in system with low maintenance cost, long service life as well as environment protection. The most important is that the panel solar geyser collector is able to deal with the problem that the system is too hot in the non-heating seasons. The panel solar geyser collector has more advantages than the evacuated tube collector in service life and maintenance of the system.
However, the domestic panel solar geyser collector exists some certain gap compare with foreign advanced level. The intercept of the momentary efficiency of domestic panel solar geyser collector is lower than that of the foreign countries, and the domestic panel solar geyser collector has lager difference with the foreign panel solar geyser collector in heat loss coefficient, which shows the domestic panel solar geyser collector has larger gap compared with other products in glass transmittance, efficient selective coating as well as whole structure design. Therefore, the domestic manufacturers need to improve the performance of the panel solar geyser collector and develop the panel solar geyser collector with high efficiency. - See more about solar water heater products at: http://en.micoe.com/waterheater/Pressuri...pper-Coil.shtml
