Abstract

The invention discloses an indirect type solar heating system for multiple groups of heat storage water tanks. The indirect type solar heating system comprises a heat collecting system, a heat exchanger, a heat storage switching system and a user terminal, wherein the heat collecting system comprises a solar heat collector and a heat-collecting circulating water pump; the heat storage switching system comprises at least two heat storage water tanks and a valve assembly; by controlling a corresponding control valve in the valve assembly, any heat storage water tank and the heat exchanger form a circulating path structure, and any heat storage water tank and the user terminal form the circulating path structure. According to the indirect type solar heating system, a plurality of three-way valves are correspondingly controlled, so that the heat collecting system and the two heat storage water tanks carry out alternative type heat-collection and heat-storage cycle; when the heat collecting efficiency of the solar heat collector is guaranteed, water temperatures in the two heat storage water tanks are kept relatively stable; and in case of guaranteeing a water supply temperature, startup time of an auxiliary heat source is reduced, energy-saving property of the system is improved and energy consumption efficiency of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization equipment, and in particular relates to an indirect solar heating system with multiple sets of heat storage tanks and a control method thereof. Background technique [0002] Solar energy is the main source of all energy on the earth. It is an endless, pollution-free and clean energy, and it is also the most promising energy that human beings can look forward to after the 21st century. my country has a vast territory, and the areas with more than 2,000 hours of sunshine per year account for about 2 / 3 of the country's area, which is in an area that is more favorable for utilizing solar energy. [0003] But solar energy is a thin energy source, and its energy density on the earth's surface is low. Moreover, the solar radiation heat has regular changes in seasons and day and night, and is also strongly affected by random factors such as cloudy, cloudy and rainy, so the solar radiatio...
