Intelligent control solar water heater having auxiliary heating function

Abstract

The invention provides an intelligent control solar water heater having an auxiliary heating function. The intelligent control solar water heater comprises a heat collector and a water tank connected with the heat collector, wherein the water tank comprises an inner container of a multilayer structure, electric heaters are installed inside the inner container which comprises four side walls and a bottom wall, the bottom wall and each side wall are respectively provided with four electric heaters, and along with increase of the heating temperature, the electric heaters are continuously and successively started to conduct heating. According to the intelligent control solar water heater, heating power can be controlled according to the water temperature, so that the inner container is prevented from being heated rapidly to expand. Meanwhile, as the heaters are installed on the side walls and the bottom wall, uniformity of the heating temperature is guaranteed.

Description

technical field [0001] The invention belongs to the field of computer control, in particular to an intelligently controlled solar water heater with auxiliary heating function. Background technique [0002] As a clean and renewable energy, solar energy has the advantages of no environmental pollution and no safety hazards, which are unparalleled by other energy sources. With the increasing tension of electricity and gas consumption across the country, solar water heaters are becoming more and more popular. Traditional solar water heaters install heat collecting tubes and water tanks on the roof of the building. The heat collecting tubes absorb the heat of the sun to increase the temperature of the water. Hot water is stored in the water tanks. When needed, hot water is introduced from outdoor hot water pipes. Indoor, for people to use. In summer, due to the long time and high intensity of sunlight, the water temperature in the water tank is too high, and the hot water canno...

AI Technical Summary

Problems solved by technology

In summer, due to the long time and high intensity of sunlight, the water temperature in the water tank is too high, and the hot water cannot be used directly. It is necessary to rely on the hot water pipe to connect with the tap water pipe, and the water temperature is adjusted by the mixing valve, so that the temperature of the outlet water fluctuates greatly. It often needs to be adjusted repeatedly during use, which is not only troublesome, but also greatly reduces the comfort of bathing

In winter, especially in the north, due to the short light time and low intensity, the hot water in the water tank often cannot reach the temperature required by people. At this time, the heater in the water tank works to heat the hot water to the required temperature first. Therefore, it is very inconvenient for people to use it in winter, and it is easy to catch a cold. Not only is the comfort of bathing poor, but it also causes a waste of water resources.
