Abstract

The invention relates to a solar water heater with three water tanks. The solar water heater with the three water tanks comprises vacuum heat collection tubes, a support, the heat collection water tank, the heat preservation water tank and the heat storage water tank. The vacuum heat collection tubes are connected with the heat collection water tank. The heat preservation water tank is arranged above the heat collection water tank. At least one return pipe is arranged between the heat collection water tank and the heat preservation water tank. The heat storage water tank is arranged below the heat preservation water tank. At least one return pipe is arranged between the heat storage water tank and the heat preservation water tank. A water delivery channel delivering water from the heat preservation water tank to the heat storage water tank is further arranged between the heat storage water tank and the heat preservation water tank. A phase-change material bag is arranged inside the heat storage water tank. The water delivery channel comprises a connecting pipe arranged between the heat preservation water tank and the heat storage water tank and a water pump arranged on the connecting pipe. The water pump is a photovoltaic water pump, and is driven by a photovoltaic power generation system and controlled by an automatic temperature switch. The solar water heater is provided with the heat collection water tank, the heat preservation water tank and the heat storage water tank, the phase-change material bag is arranged inside the heat storage water tank, so that the heat storage function is achieved, hot water service time can be prolonged, and the requirement for using hot water can still be met on a rainy day after fine weather.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, in particular to a solar water heater with three water tanks. Background technique [0002] Solar energy is an inexhaustible and inexhaustible green energy, and solar energy utilization technology has been paid more and more attention. Solar water heaters convert sunlight energy into heat energy, heat water from low temperature to high temperature, and can meet people's hot water use in life and production. Therefore, in daily life, solar water heaters are more and more widely used. Solar water heaters usually include heat collecting components (vacuum heat collecting tubes or flat plate heat collectors), heat preservation water tanks and supports. Existing solar water heaters have a good heat collection effect in fine weather and are satisfactory in use. However, if it encounters rainy weather, it cannot achieve the ideal use state because it cannot collect heat normally. In ...
