<p>Space-heating system which has a fluid as the heat-transporting medium. The system comprises a heat store (9) with a heat-storing medium through which the fluid can flow. The heat store (9) is in communication with two pressure-equalizing chambers (10, 11) arranged on either side of the heat store, one of which (10) normally has a higher temperature than he other (11), due to the heat storing. Each of the chambers is connected by means of a heat-transporting fluid duct (12) to a heating arrangement (13, 14, 15). With the aid of a fan or pumping element the fluid is made to flow from the heating arrangement (13, 14, 15) to the hottest chamber (10), through the heat-storing medium in the heat store (9) and into the coldest chamber (11), and thereafter back to the heating arrangement (13, 14, 15). When the fluid flows through the heat store (9) in this direction, the heat-storing direction, the heat-storing medium takes up heat from the heat-transporting fluid. According to the invention the heating system comprises another heat-transporting fluid duct (19) which connects the two said chambers (10, 11) to the space (20) which is to be heated. With the aid of a fan or pumping element the heat-transporting fluid is made to flow from the hottest chamber (10) via the space (20) to the coldest chamber (11) and through the heat-storing medium in the heat store (9) in a direction, the heat-withdrawal direction, which is opposite to the heat-storing direction, the fluid taking up heat from the heat-storing medium. </p> |
