PROBLEM TO BE SOLVED: To provide a heat medium discharge device and a heat medium discharge method capable of discharging a heat medium from a solar heat collector by gravity force without installing a tank at a position lower than the solar heat collector.SOLUTION: A heat medium discharge device includes a vent portion 15 disposed at the highest position of a heat medium flow channel 2 of a solar heat collector 1, an inclined pipe 5 connected to the heat medium flow channel 2, a drain container 16 connected to a position lower than a part connected with the heat medium flow channel 2, of the inclined pipe 5, and a pump 20 for sending the heat medium from the drain container 16 to a tank 6. In discharging the heat medium, as the heat medium is allowed to flow in the heat medium flow channel 2 and the inclined pipe 5, and then received in the drain container 16 by gravity force by opening the vent portion 15 and introducing the air, and further the heat medium is sent to the tank 6 by the pump 20, the heat medium can be discharged from the solar heat collector 1 by gravity force without installing the tank 6 at a position lower than the solar heat collector 1. |
