<p>PURPOSE:To contrive to efficiently accumulate the hot water in a heat accumulator by a structure wherein the heat exchange section of a heat exchanger is arranged in a heat exchanger jacket, at the lower part of which a convection influx port is provided and at the upper part of which a convection efflux port is provided so as to flow heated water out through a hot water conduit connected to the efflux port into the upper portion of a heat accumulator equipped with the heat exchanger. CONSTITUTION:A heat exchanger 3, which is heat-exchanged and heated by means of a circulating pump 6, is installed in the interior of a heat accumulator 2, to which a solar heat collector 1 is connected with piping. The heat exchange section of the heat exchanger 3 is arranged in a heat exchanger jacket 4, at the lower part of which the convection influx port 4a of the water 7 in the heat accumulator 2 is provided and at the upper part of which the convection efflux port 4b of the hot water 7 in the heat accumulator 2. In addition, a hot water conduit 5 to flow the water heated in the jacket 4 out into the upper portion of the heat accumulator 2 is provided to connect to the convection efflux port 4b so as to be able to accumulate said heated water without mixing with the unheated water 7 in the heat accumulator 2. Consequently, hotter water can more efficiently be accumulated from the upper portion of the heat accumulator.</p> |
