Document Type and Number:
Japanese Patent JP2012077976
Kind Code:
A
Abstract:
To provide a solar heat collector which is of high efficiency and enables a heating medium to get a sufficiently high temperature.
The solar heat collector includes a heat collection portion (41) which condenses sun light, a refrigerant piping (45) in which a refrigerant of supercritical state circulates, while being arrangedly provided in a focal point (44) of the heat collection portion (41). The heat collection portion (41) is configured so that the condensing ratio becomes large, as it goes toward an outlet side from an inlet side of refrigerant piping (45), and the refrigerant piping (45) is configured so that the flow passage cross section of the refrigerant becomes large, as it goes toward the outlet side from the inlet side.
