Intelligent control solar water heater with heat collector with constant temperature

Abstract

The invention provides an intelligent control solar water heater with a heat collector with the constant temperature. The solar water heater comprises the heat collector and a water tank connected with the heat collector. An adjusting unit generates an adjusting signal controlling a first flow controller according to the measured values from a temperature sensor, an illumination sensor and a flow meter to change the flow of water flowing into the heat collector, and then the temperature of the fluid in the heat collector is kept constant. The temperature of the water in the heat collector can be automatically controlled to be constant.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to an intelligently controlled solar water heater with constant heat collector temperature. 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 ...

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.
