Intelligent hot water distribution multi-user solar water heating system

Abstract

The invention discloses an intelligent hot water distribution multi-user solar water heating system. The system comprises a solar heat collector, a water tank, user water-using terminals, a connecting water tank, a hot water output pipe of each user water-using terminal and a cold water input pipe of each user water-using terminal, wherein a first intelligent controller is arranged in front of each user water-using terminal; the water inlet end of the solar water collector is provided with a water level and water temperature sensor; the water tank is provided with a second intelligent controller; each intelligent controller comprises a microprocessor, a flow sensor, an electromagnetic valve, a temperature sensor, a display screen, a keyboard and a communication interface; the microprocessor is communicated with other components of the intelligent controller; and all intelligent controllers communicate with each other through a communication interface. The system has the advantages of remarkably enhancing solar energy utilization efficiency, reducing energy source consumption, meeting the requirement of most users in a user group on basic solar hot water amount to the maximum extent, allowing the users to set the hot water using mode and using amount of the system according to practical requirements, lowering system running difficulty and remarkably expanding the range of application.

Description

technical field [0001] The invention relates to a solar water heating system, in particular to an intelligent hot water distribution multi-user solar water heating system. Background technique [0002] The energy consumed by human beings is increasing day by day, most of which come from burning fossil fuels, which will not only cause the fossil fuels to be exhausted ahead of time, and human beings will fall into an energy crisis, but also the emission of greenhouse gases such as carbon dioxide will make the greenhouse effect more and more obvious, bringing serious consequences, such as pests and diseases Increased sea levels, climate anomalies, increased ocean storms, land drought, increased desertification, and decreased food production are endangering human survival. Energy conservation and emission reduction, and the use of clean energy are not only a matter of saving fuel, but also a key issue related to human life. [0003] Solar water heaters are the simplest and most...

Problems solved by technology

The household type means that each household is an independent system, which does not affect each other, and there is no problem of flow distribution and complicated control among households. However, due to the unbalanced use of hot water among households, resulting in The solar heat collection facilities cannot be fully utilized, the utilization rate of solar energy is not high, and there are many pipelines in the system, which makes the implementation difficult, making the cost relatively high, such as figure 1 shown

Centralized refers to centralized heat collection and central heating. The system is highly integrated, the pipeline is simple, and the energy utilization rate is high, but the cost calculation is complicated. For example, the density of hot water is not balanced due to the overall operation of the meter. Or adopting an unlimited water supply method with a fixed hot water usage fee will also cause energy waste, or some users cannot use hot water
