A method and arrangement for the defrosting of solar collectors

摘要

It is a method for the defrosting of solar collectors (2 to 5) as well as a solar collector - arrangement, according to the invention by means of a solar energy in the heating mode, the solar collectors is heated heat carrier flowing through a heating. At the beginning of a defrosting process, produce a snow-free defrost heater for the collector (1) and a solar collector (2) to a defrost heater circle barrel (ak) connected together, wherein, after reaching a defrost heater for the limit value to the solar collector (2) is successively further solar collectors (3 to 5) of the solar collector - arrangement on the defrost heater circle barrel (ak) is switched on and in succession to be defrosted.
