Document Type and Number:
WIPO Patent Application WO/2023/024327
Kind Code:
A1
Abstract:
The present invention relates to the technical field of solar heating and gas heating, and provides a solar and gas complementary heating system. The system comprises a solar water heater (1), a water softener (2), a softened water tank (3), a circulating water pump (4) and a gas water heater pipe network (5), wherein the water softener (2) is arranged on a tap water input pipeline and is used for softening water; an automatic water supplement pressure regulation valve is provided on a pipeline between the water softener (2) and the softened water tank (3); the solar water heater (1) is connected to the softened water tank (3); and the softened water tank (3) is connected to the gas water heater pipe network (5) by means of the circulating water pump (4). The automatic water supplement pressure regulation valve regulates the water supplement pressure depending on the duration of sunshine, and a water level indicator is provided in the softened water tank (3). Water in the solar water heater (1) flows back to the softened water tank (3), and the circulating water pump (4) pumps hot water to a water supplement device of the gas water heater. The system can reduce the energy consumption of a gas-fired boiler, achieves mutual complementation of solar energy and gas, and is energy-saving and environmentally-friendly.
