Description
Technical Field

Background
At present, a gas-type or electric heating-type hot water system is generally adopted for a hot water supply system of a building house, particularly a high-rise building house, and the conditions of relatively fixed time, relatively low stage water consumption, relatively high water consumption frequency (tap switching frequency) and the like are generally adopted for the hot water supply requirement of the house. In the case of a gas or electric heating type hot water system, frequent start-up, continuous operation, etc. are likely to occur, and power loss, frequent heating of hot water, etc. are likely to occur.
With the wide application of new energy and the continuous proposition of national energy conservation and emission reduction concepts, solar energy is widely applied and popularized in various aspects as a novel clean energy, a solar water heater is widely applied to low-rise buildings, solar power generation is effectively popularized at present, and related application technologies are gradually improved and mature.
The prior art mainly comprises corresponding detection and control technologies, and the detection technologies mainly apply corresponding sensors to carry out corresponding numerical values and parameters, which mainly comprise corresponding parameters such as water temperature, water level, water flow and the like. The control technology takes a corresponding controller as a core, and the system is analyzed, judged and controlled by programming to realize the supply of the controlled water supply quantity of the switch valve and the regulation and control of the water temperature.
Aiming at a new energy hot water supply system in the current market and a corresponding patent scheme, a solar water heater is mainly used, water is heated and controlled through a heat collecting pipe, and then the water temperature is adjusted and controlled through pipeline transportation.
The existing hot water energy-saving scheme mainly realizes the control of a water flow path and the circulating treatment of hot water by opening and closing a valve and conveying a water pump, and has relatively large demand on external new water quantity in the using process.
For the maintenance of the water temperature, a multi-stage water tank electric heating mode is adopted to realize constant temperature maintenance.
However, the solar water heater occupies a relatively large area, is basically abandoned in high-rise and super high-rise buildings at present, is limited by weather conditions in use time, and has poor hot water effect when used in rainy days or cold seasons. Meanwhile, the regulation and control of the water temperature are not easy to control, and the temperature is greatly influenced by the illumination intensity. The existing hot water circulation and water saving devices basically need to be added with a water pump to realize hot water circulation, have relatively high cost and are not suitable for household systems. But also virtually increases the energy consumption loss. While the time of use of a household hot water system is relatively constant, the temperature of the current hot water system needs to be kept stable throughout the day. It is relatively easy to cause loss of energy consumption. The existing solar water heater has relatively large dependence on the environment, needs to additionally add other hot water supply systems to maintain the stability and the continuity of water supply, and basically depends on the other hot water supply systems to realize the supply of hot water in night time.
