PURPOSE:To increase the heat collecting efficiency of a heat collector, by providing a pulsation generator or a pulsating pump. CONSTITUTION:A pump 2 for supplying water to a heat collector 3 is provided, and the heat collecting water leaving the pump 2 is passed via headers 5, 6 into the heat collector 3. In the heat collector 3, a water passage 7 is provided, and the water from the header flows into the water passage 7 where solar energy is collected. The streams absorb the solar energy to become hot water streams, are collected into the upper header 6, and merge with streams from other heat collectors, and the merged steram is passed via a return pipe into a heat accumulating tank 4 where it is stored. In this case, a pulsation generator 1 is attached to the pump 2 to feed water to the heat collector or instead of the pump 2, a reciprocal type pump is used to generate pulsation. |
