Patent ID: 8468827

Claim:
A heating medium supply system comprising: a heating system configured to heat a liquid heating medium by sunlight; a heat exchanging device configured to heat water supplied thereto by means of the heating medium supplied thereto from said heating system; a heating medium supply passage for supplying the heating medium from said heating system to said heat exchanging device; and a heater for heating the heating medium and a temperature measuring device configured to measure a temperature of the heating medium, which are provided on said heating medium supply passage, wherein the heating medium supply passage is provided with a temperature fluctuation suppressing device for suppressing a temperature fluctuation of the heating medium, the temperature fluctuation suppressing device being provided in a flow path of the heating medium, downstream in a heating medium flow direction of the heater on the heating medium supply passage; wherein the temperature fluctuation suppressing device has plural heating medium passages allowing the heating medium to pass therethrough, and an inlet and an outlet for the heating medium; whereby the heating medium flowing into said temperature fluctuation suppressing device from said heating medium supply passage through said inlet is allowed to pass through said plural heating medium passages at time-lags to form respective streams, which are then joined together before flowing out of said temperature fluctuation suppressing device into said heating medium supply passage through said outlet.
