Description

Technical Field

[0001] This utility model relates to the field of dual-source hot water systems using solar energy and air energy, specifically an automatic water replenishment device for dual-source hot water systems using solar energy and air energy. Background Technology

[0002] A dual-source hot water system combining solar and air energy technologies is a hot water supply system designed to provide an efficient, energy-saving, and stable hot water solution. This system requires automatic water replenishment.

[0003] In the prior art, such as in the publication number CN207815750U, an automatic water replenishment mechanism for a dual-source hot water system of solar energy and air energy is disclosed. It includes a water supply tank, a solar water tank, a heat pump hot water unit, a solar collector structure, a temperature detection module, and a cold water replenishment end. Each cold water replenishment end is equipped with a water replenishment solenoid valve. The temperature detection module is connected to a liquid level controller. A water level sensor is installed in the water supply tank and / or the solar water tank. The water level sensor is connected to the liquid level controller. The water supply tank is provided with a cold water upper limit water level line and a hot water upper limit water level line in sequence. The height of the cold water upper limit water level line is higher than the height of the hot water upper limit water level line.

[0004] While the aforementioned patent utilizes solar energy and air source heat as heating energy for hot water, combining the advantages of solar and heat pump water heaters—offering energy savings, environmental friendliness, and high efficiency—it can automatically replenish water according to system conditions without manual supervision, automatically controlling the water level in the tank and effectively saving energy. However, during automatic water replenishment using solar energy, the large size of the water tank means that water containing impurities and scale can be added, making subsequent tank cleaning difficult and affecting water quality. Furthermore, regular maintenance of the water replenishment device is required, but the disassembly and assembly process is complex, leading to inconvenience and increased maintenance time. Therefore, to address these issues, an automatic water replenishment device for a dual-source hot water system combining solar and air sources is proposed. Utility Model Content
