| 摘要 |
The invention relates to a method for providing heat for heating buildings and, optionally, for heating up process water by way of a solar collector (1), wherein the solar collector (1), during solar irradiation, is filled with a heat transfer medium flowing through said collector in order to heat the heat transfer medium, and wherein the solar collector (1) is otherwise emptied, wherein the heat transfer medium is collected in a storage container (2). A simple, robust and efficient system is attained by keeping the heat transfer medium in the storage container (2) and in the solar collector (1) under increased pressure, by the storage container (2) being filled in all operating states partially with heat transfer medium and partially with gas, and by the heat transfer medium being withdrawn directly for heating the building from the storage container (2). Further, the invention relates to a device for carrying out the method. |
