Novel solar water heating system

Abstract

The invention discloses a novel solar water heating system comprising a solar water heater body and further comprising a water storage tank and a control system. The water storage tank is connected with a water tank of the solar water heater body through a water inlet pipe and a water outlet pipe. One ends of the water inlet pipe and the water outlet pipe are connected to the two sides of the water tank of the solar water heater body correspondingly, and the other ends of the water inlet pipe and the water outlet pipe are connected to the two sides of the water storage tank correspondingly. An electromagnetic valve A is arranged on the side, close to the water storage tank, of the water inlet pipe. An electromagnetic valve B is arranged on the side, close to the water storage tank, of the water outlet pipe. A water temperature and water level sensor is arranged inside the water storage tank. The water storage tank is sleeved with a detachable heat preservation layer. A water adding pipe and a water using pipe are further arranged on the water storage tank. An electromagnetic valve C is arranged on the water adding pipe. The control system is connected with a water temperature and water level sensor of the solar water heater body, the electromagnetic valve A, the electromagnetic valve B, the water temperature and water level sensor and the electromagnetic valve C independently, water scale and water boiling for a long time can be effectively prevented, and thus the vacuum heat collection pipe type solar water heating system is used more safely and conveniently.

Description

technical field [0001] The invention belongs to the technical field of solar energy equipment, and in particular relates to a novel solar water heating system. Background technique [0002] Solar energy is a very clean energy. Solar water heaters are devices that use solar energy to heat water. They are divided into vacuum tube solar water heaters and flat plate solar water heaters. part of the market share. [0003] The existing vacuum tube solar energy is composed of heat collecting tubes, water storage tanks and brackets and other related components. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required However, as long as the vacuum heat collecting tube is exposed to sunlight, the temperature of the water will increase, and no control measures have been taken to control the temperature increase of the water....

[0003] The existing vacuum tube solar energy is composed of heat collecting tubes, water storage tanks and brackets and other related components. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required However, as long as the vacuum heat collecting tube is exposed to sunlight, the temperature of the water will increase, and no control measures have been taken to control the temperature increase of the water. In summer when the sunlight is strong, the temperature of the water will often rise directly to its boiling point of 100 ℃, in some areas with relatively hard water quality, very serious scale will be produced. The harm of scale to vacuum heat collecting tubes is well known, and it will also block water pipes. Moreover, because the temperature of tap water is basically 20 to 30 degrees in summer, the temperature is very high. High solar energy water is used slowly in summer, so it will often boil in the water storage tank, forming "thousand boiling water", which will bring certain harm to human body during people's bathing and use, and the temperature is so high Solar water may also cause accidents such as burns, especially for children with poor self-protection awareness. At the same time, in the cold winter, the sunlight exposure time is short and weak, and there is a problem that the supply capacity of solar water heaters is obviously insufficient
