| 摘要 |
The present invention relates to a system (1) or a method for heating of an enclosed space (2) comprising a solar collector (11), adapted to use air as heat-carrying medium, placed on the outside of the space (2), as well as a fan (13) adapted to, upon a heating of the space (2), generate an inward flow (31) of heated air from the solar collector (11) to the space (2). The present invention teaches particularly that the system (1) is adapted for a cooling down and simultaneously maintained ventilation of the space (2), that the fan (13) is adapted to generate an outward flow (32) of air from the space (2) to the solar collector (11), and that the outward air flow (32) is adapted to cool down the solar collector (11) and thereby decrease the stagnation temperature of the solar collector (11).
