PURPOSE:To raise the feeding performance of heat as well as the reliability of valve mechanism by providing a liquid level sensor in a subtank whose side is closely joined with a liquid trap tank and the lower part is provided with a communication hole. CONSTITUTION:A subtank 14 is partly joined with a liquid trap tank 7 at its side and provided with a communication hole in its lower part. A liquid level sensor 6 is housed in the tank 14 whose upper part is enclosed in such a way that the variation in the liquid level of a working liquid 12 in the tank 7 is delayed from the variation in the liquid level in the tank 14 and the difference between the upper stop liquid level and the lower stop liquid level of the liquid 12 in the tank 7 is made greater. The opening and closing frequency of the valve 10 is reduced according to the amount of heat to be fed, the performance of the heat exchanger is raised, and the disorder of the valve 10 is avoided. |
