Solar water heater intelligently controlled according to period of time

Abstract

The invention provides a solar water heater intelligently controlled according to a period of time. The solar water heater comprises a heat collector and a water tank connected with the heat collector, wherein the flow in the heat collector can be adjusted according to periods of time. By using the solar water heater, the flow in the heat collector can be adjusted according to the periods of time, so that the effluent temperature of the heat collector can be kept constant.

Description

Technical field [0001] The invention belongs to the field of computer control, and particularly relates to an intelligent control of a solar water heater according to a time period. Background technique [0002] As a clean and renewable energy, solar energy has the advantages of no environmental pollution and no safety hazards unmatched by other energy sources. With the increasing shortage of electricity and gas throughout the country, solar water heaters are becoming more and more popular. Traditional solar water heaters install heat collection tubes and water tanks on the roof of the building. The heat collection tubes absorb the heat of the sun to raise the water temperature, and the hot water is stored in the water tank. When needed, the hot water is introduced from the outdoor hot water pipe. Indoors, 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 cannot be used direct...

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.
