Abstract

PURPOSE: To eliminate electric wiring of a domestic hot water system, by interlocking a pump with a liquid level meter for using the volumetric expansion of a heat carrying medium caused by the solar energy as a switching device of the pump.
CONSTITUTION: The solar energy collected by a solar collector 10 raises the temperature of a heat carrying medium while expanding its volume. As the heat medium reaches at around 60°C, the water level rises up to a point b and a float 17 of a liquid level switch 12 also rises up to the point to close an electric circuit. Then a pump 13 gets started and the heat medium circulates. The heat carrying medium heated by the solar collector 10 enters an indirect heat exchanger 15 to transfer its energy to water in a hot water storage tank 14 and returns to the collector 10 after being cooled. As the water temperature in the storage tank 14 reaches the level of 60°C, a thermo switch 16 is turned off to interrupt the motor operation.
