PURPOSE:To improve the operation efficiency and stabilize the operation in response to fluctuations in a heat source for drive by changing over between a heat cycle operation which uses three types of hydrogen occluded alloys and a heat cycle operation which uses two types of hydrogen occluded alloys out of said hydrogen occluded alloys responding with a temperature level of a drive heat source in said heat cycle operation. CONSTITUTION:Three types of hydrogen occluded alloys MH1, MH2, and MH3 execute a heat cycle operation which uses total alloy when the supply heat of a drive heat source is relatively low, say, 90 deg.C. When the supply heat of a drive heat source is relatively high, say, 130 deg.C and over, the alloy MH2 is eliminated and MH1 and MH3-based heat cycle operation is executed. A control device in which a measured temperature value of the supply heat of a drive heat source 18 is input, compares with 130 deg.C or equivalent intensity of solar radiation. The contrl device, if it exceeds this standard, indicates a heat cycle operation which uses two types of alloy MH1 and MH3, or if it fails to exceed the standard, the control device indicates a heat cycle operation which uses a total of three types alloy and opens and closes on/off valves 19 to 16 and a change over valve 20 so that they may conform to each operation. |
