Abstract
PURPOSE: To save power by separating water-lifting pump from water circulation pump whereby water could be circulated by a water circulation pump of small capacity.
CONSTITUTION: Water circulation pump 5a starts operation by the openings for an amount of the prescribed temp. at the upper 16a and the lower 16b temp. difference sensors, and because at that time, water surface switch 11 is closed, solenoid valve 8 is opened which closes the pressure switch 7. By this action, hot water pump 4 starts operation which makes water pour into the water bowl 10 thru return pipe 13 after filling the solar heat collector 1. When the water bowl 10 is fully filled, its water surface reaches the tip of the return pipe 13 and the solenoid valve 8 is closed. This action increases the pressure within the hot water pipe 17 and stops operation of the hot water supply pump 4. Water circulation to be performed afterward is regulated by the water head difference between the surface of the water bowl 10 and the hot water tank 2a, and the water circulation is performed by the operation of the pump 5a whose capacity is only larger than the aggregated sum of the resistances of water passages concerned, and the required electric power is saved to a great degree.
