Intelligent solar water heater system and control method based on single-chip microcomputer control

Abstract

The invention discloses an intelligent solar water heater system and a control method based on single chip microcomputer control. The intelligent solar water heater system comprises a water supply end, a user end and a single chip microcomputer control system. A hot water tank and a cold water tank are arranged on the water supply end, and one or a plurality of buffer water tanks which are in one-to-one correspondence to a water outlet end are arranged on the user end, so that on one hand, hot water in the hot water tank and cold water in the cold water tank can be mixed so as to adjust the temperature in the buffer water tanks first and then are supplied to the water outlet end, a user can quickly use hot water at the stable temperature, and severe water temperature fluctuation is effectively avoided when the user uses the hot water, and on the other hand, the requirements of multiple users on the hot water at different temperatures in different environments can be satisfied. In addition, the single chip microcomputer control system is arranged, so that the water temperature and water level of the hot water tank and the water temperature and water level of the buffer water tanks can be automatically monitored and adjusted, the intelligent control over a solar water heater is realized, the manual operation frequency is reduced, and the operation and the complexity in use are simplified.

Description

technical field [0001] The invention relates to a solar water heater, in particular to an intelligent solar water heater system based on single-chip microcomputer control and a control method thereof. Background technique [0002] A solar water heater is a heating device that converts solar energy into heat energy. It uses solar radiation to heat water from low temperature to high temperature, so as to meet the needs of hot water in people's life and production. It has the advantages of energy saving, environmental protection, no pollution, convenient use and low cost. [0003] But, also there are some defects in present solar water heater. For example, the use effect is greatly affected by weather and seasons. Although electric heating devices can be used to assist heating, the water temperature is still difficult to adjust. And it is also difficult to meet the needs of families for hot water at different temperatures. [0004] Aiming at the problems existing in solar wa...

Problems solved by technology

Among them, patent CN104864614A proposes a scheme for intelligently adjusting the hot water temperature of solar water heaters, which can reduce the waste of energy caused by electric heating, but it does not take into account the needs of different users and environments for different temperatures and different amounts of hot water

Patent CN103836819A proposes a solar water heater intelligent management system based on AT89C51 single-chip microcomputer. This invention uses a high-precision temperature sensor to accurately control the temperature, but the defect is that it also does not consider the requirement of hot water that can quickly reach the temperature required by the user.
