Description

Temperature-controlled solar water heater

Technical Field

The application belongs to the technical field of solar water heaters, and particularly relates to a temperature-controlled solar water heater.

Background

The solar water heater is a heating device for converting solar energy into heat energy, and heats water from low temperature to high temperature so as to meet the requirement of hot water in life and production of people. The solar water heater is divided into a vacuum tube type solar water heater and a flat plate type solar water heater according to the structural form, mainly uses the vacuum tube type solar water heater as a main part, and occupies 95 percent of domestic market share. The vacuum tube type domestic solar water heater is composed of heat collecting tube, water storage tank and support, and can convert solar energy into heat energy, and mainly depends on the vacuum heat collecting tube, and the vacuum heat collecting tube can utilize the principle of that hot water floats upwards and cold water sinks to make water produce microcirculation to obtain the required hot water. Normally, hot water is used more in winter, and is rarely used in summer, particularly in high-temperature seasons, but the temperature of the water inside the solar water is easy to rise quickly in summer, and the water temperature is often as high as 98-100 ℃ in the high-temperature seasons. Water at such high temperatures can cause several disadvantages:

1) scalding is easy, and the body is easy to scald due to the fact that the mixing valve is not controlled in the daily bathing process;

2) the service life of the pipeline is easily influenced. The pipeline connected with the solar energy heat collector is mostly provided with plastic pipes, the upper limit of the high temperature bearing temperature of the normal plastic pipe is 95 ℃, and if the water temperature of the pipeline exceeds 95 ℃ for a long time (even reaches 98-100 ℃), the service life of the pipeline is influenced;

3) the water circulation is reduced, and the quality of the produced water is easy to change. Because less hot water is used in summer, high-temperature hot water stored in a water tank of the solar heat collector for a long time cannot be recycled in time, and the water quality change is influenced after a long time, so that the human body is injured;

4) the water in the water tank is always in an evaporated state at a boiling point temperature for a long time, i.e., water resources cause waste.
