Multi-storey solar water heater

Abstract

The invention discloses a multi-compartment solar water heater, which comprises a water tank, a first water compartment, a second water compartment, a third water compartment and a fourth water compartment, and a controller. A first circulating pump is used for pumping water in the first water compartment into the second water compartment; a second circulating pump is used for pumping water in the second water compartment into the first water compartment; a third circulating pump is used for pumping water in the second water compartment into the third water compartment; a fourth circulating pump is used for pumping water in the third water compartment into the second water compartment; a fifth circulating pump is used for pumping water in the third water compartment into the fourth water compartment; a sixth circulating pump is used for pumping water in the fourth water compartment into the third water compartment. The controller regulates the flows of the first circulating pump, the second circulating pump, the third circulating pump, the fourth circulating pump, the fifth circulating pump and the sixth circulating pump according to a first temperature difference, a second temperature difference and a third temperature difference. The multi-compartment solar water heater has four water compartments; when water is fed, the mixing speed of cold water and original hot water is slow, so hot water shock cooling is avoided, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of solar water heaters. More specifically, the present invention relates to a multi-chamber solar water heater. Background technique [0002] Solar water heater is a device that converts sunlight energy into heat energy, heats water from low temperature to high temperature, and provides sufficient hot water for people's life and production. However, at present, many solar water heaters are a water tank, and this kind of solar water heater cannot be used even after absorbing solar energy for a long time, and after the water is supplied, the cold water is directly mixed with the hot water, which neutralizes the original hot water temperature, causing A lot of energy wasted. Some solar water heaters have an electric heating function, but because the heating range is too large, the heating speed is slow and the power loss is large. Therefore, it is urgent to design a novel solar water heater with low energy consumption...

However, at present, many solar water heaters are a water tank, and this kind of solar water heater cannot be used even after absorbing solar energy for a long time, and after the water is supplied, the cold water and the hot water are directly mixed to neutralize the original hot water temperature, resulting in waste of energy

Some solar water heaters have electric heating function, but because the heating range is too large, the heating speed is slow and the power loss is large.
