A solar layered water storage tank and its system

Abstract

The invention relates to a solar layered water storage tank and its system, including a solar energy system, a layered water storage tank, and a heating system; Independent, high heat exchange efficiency, the medium in the heat collection part is antifreeze, which can effectively prevent the solar collector and heat collection circulation pipe from freezing caused by the temperature difference between day and night, with strong practicability and good antifreeze effect. When the heat collection cycle is stopped, the heat storage tank can also be used as a return water tank, and part or all of the medium in the solar collector and pipeline returns to the heat storage tank, which can effectively prevent freezing and prevent the solar collector from overheating. In the solar system using the hot water storage tank, the heat enters the hot storage tank through circulation, recirculates or transfers to the heating system for heating, and the heat is circulated for heating. The good stratification of the heat storage tank reduces the inlet temperature of the heat collection cycle and increases the heating temperature, which can not only effectively improve the efficiency of the heat collector, but also make full use of the heat.

Description

technical field [0001] The invention relates to the technical field of solar heat storage, in particular to a solar layered heat storage tank and a system thereof. Background technique [0002] The heat storage tank in the existing solar energy system is not equipped with a layering device, the medium in the heat storage tank is easy to stir and mix the water, and the medium in the water tank is basically at the same temperature, resulting in high inlet temperature of the solar collector. The efficiency is reduced; at the same time, it affects the heating temperature, resulting in low heating temperature and poor heating effect. [0003] The solar collectors and most of the pipes are exposed to the outdoor space. The weather is cold, especially at night when the ambient temperature is low. When the circulation speed slows down or does not circulate during the heat collection cycle, the liquid in the pipes is easy to freeze, which is not conducive to the heating and cooling o...
