Abstract

PURPOSE:To make absorptivity of radiation heat of solar heat of a heat medium variable by providing a system which is capable of collecting heat receiving particles selectively within a heat medium circulating circuit, in the titled device in which a fluid wherein the heat receiving particles are suspended. CONSTITUTION:Under normal heat collecting operation, a valve 11 is kept closed, while a valve 12 is kept open, a pump 3 is driven, and a heat medium made up of mixing of heat receiving particles with a liquid, such as water is sent to the inside of a duct 4 in a solar heat collecting board 1 through a passage 10 and a valve 12 in a collector 6. Then, the heat medium heated by solar heat is discharged from the top of the duct 4 and is led to a heat exchanger 2 so that water and air are heated. On the other hand, valve 12 is closed and the valve 11 is opened when solar radiation heat is increased further and the heat medium is about to boil. With this, the heat receiving particles in the heat medium are collected on a filter film 8 of the collector 6, and absorptivity of solar radiation heat of the heat medium is reduced to prevent boiling.
