PURPOSE:To control temperature excellently, by additionally heating a secondary fluid heat absorbing and radiating material by a main fluid light absorbing and heat radiating material having reversible isomerization reaction property in a circulating path, and suppressing the temperature fluctuation in the secondary material due to the sunshine variation. CONSTITUTION:In a compound type collector 1, the main light absorbing and heat radiating material 2 such as norbornadiene (2,5-bicycloheptadiene), which has reversible isomerization reaction property and which is made fluidic by a solvent, collects light energy. The secondary heat absorbing and radiating material 3 such as water directly collects heat energy in the collector 1. The secondary material 3 circulates through a storage tank 6, a heat exchanger 5, and heating radiators 7. The main material 2 enters the heat exchanger 5 through a storage tank 4. When the heat absorption of the secondary material is not sufficient and its temperature does not reach a desired temperature, the material 2 is additionally heated and returned to the collector 1. In this way, collection and storage of the solar light energy are performed in the form of heat energy and the chemically bonded energy. Therefore, the temperature fluctuation of the secondary material due to the sunshine variation can be suppressed, and the excellent temperature control can be performed.
