Solar heat system
Patent
·
OSTI ID:6277344
A valve module is provided which finds particular utility in a domestic solar water heater system. The solar water heater system includes a collector, a storage tank, and a circulating pump. The system also includes a solid state electronic control module which automatically stops the circulating pump when the temperature of the water in the collector drops below the temperature of the water in the storage system, so that water is circulated through the system only when solar heat is available to heat the water to a temperature above the temperature of the water already stored in the storage tank. The valve module, upon a signal from the control module, causes the water to drain out of the collector when the temperature of the water in the collector falls to freezing temperatures so as to prevent damage to the collector. The control module also serves to stop the pump , to close the valve module, and to drain the collector when the temperature of the water in the storage tank reaches a predetermined maximum temperature.
