Abstract

PURPOSE:To prevent the heat medium from boiling by a method wherein when the temperature of the heat medium is higher than a predetermined temperature, thermo- responsive valves branched off from a heat medium circulation circuit between the input and output side of a heat collector are opened to thereby stop a heat medium circulation pump and a heat medium supply device. CONSTITUTION:The thermo-responsive valves 4 and 6 which form bypass circuits are provided in the heat medium circulation circuit including a heat collector 1, a heat medium circulation pump 2 and a heat exchanger 3 and the output side of the valves 4 and 6 are connected to a heat medium tank 7. Further, the heat sensitive section 4a of the thermo-responsive valve 4 and the heat sensitive section 6a for the thermo-responsive valve 6 are provided in the heat medium circulation circuit and a heat medium supply tank 8 is connected to the lower part of the heat medium tank 7. With the above arrangement, when the temperature of the heat medium comes close to its boiling point, the heat sensitive sections 4a and 6a for the valves 4 and 6 detect it to open the valves 4 and 6 so that the heat medium in the heat collector 1 is taken out due to its head and the operations of the circulation pump 2 and an auxiliary pump 11 are stopped throgh contacts 4a and 6b.

In the above configuration, when setting the temperature of each heat-responsive valve (4-(6)), set the temperature on the inlet side of the heat collector (1) to be lower than the temperature on the outlet side in anticipation of a rise in the heat medium. (For example, 9O-C on the inlet side and 97-C on the outlet side) Also, each heat-responsive valve (41 (61) Ir1s heat section (4S (6a) is installed below the branch point. This is because if the heat collector (11) is installed higher, after the heat medium in the heat collector (11) is removed, it will become a hole to measure the air knitting in the circulation circuit, causing an inconvenience. (6λ) above the bifurcation point, provide a tower or heat medium tank (
It is necessary to raise the position of 7) and constantly measure the heat medium.If the temperature of the heat medium becomes lower than the set value due to an abnormality on the load side of the heat exchanger (31), The heat-sensitive fjAs (4a) (6a) of a-responsive valves (41 (61) detect this, and each heat-responsive valve (4' (61) becomes "open", so the heat medium in the collector <11 At the same time, the heat-responsive valve (41 (installed in the main body of 61) and the f contacts (4b) and (6b) become 0), and the circulation pump (2) and replenishment pump 00 are turned off. Stop operation.
