[0021] When the first control valve 610 connects the first outlet 220 with the first heat source 600, and the third control valve 620 connects the first control valve 610 with the first heat source 600, the heat medium returns to the first heat source 600 after passing through the first heating pipe 200 to complete the cycle.
