A forward feed conduit (43) conducts the heat-carrying fluid (2) from the first heat exchanger (10) to the receiver (20). The forward feed conduit incorporates an upper connection conduit (41) provided with an expansion chamber (52) and which establishes the heat-carrying fluid in the system in a first fluid column (3) and a second fluid column (4). The two fluid columns communicate with each other via the upper connection conduit. The first heat exchanger heats fluid in the first fluid column. A third heat exchanger (30) is arranged in the system and evaporates fluid in a partial flow from the first and/or second fluid columns, feeding the thus formed gas bubbles (5) to the first fluid column (3). The gas bubbles flow up through the first fluid column and produce a flow of fluid from the first fluid column to the second fluid column via the upper connection conduit and further to the receiver (20). |
