But maybe the amount of hot water needed at this time is not large. If the solar energy that can be gathered is used to heat a small part of the water, the water temperature can reach the set temperature. Therefore, the above solar water heating system cannot make full use of solar energy. Provide hot water, wasting more auxiliary energy

Embodiment Construction
[0036] The present invention replaces the large water tank in the solar water heater with a plurality of relatively independent and smaller water tanks, and heats the water in each water tank in turn, so that the water in each water tank can be warmed up quickly, and when the solar energy is not sufficient It can heat the water in some of the water tanks to the set temperature, and provide users with water at a suitable temperature without heating by the auxiliary heat source, so as to achieve the purpose of saving the auxiliary heat source.
[0037] The solar hot water supply system and its heating method of the present invention will be described in detail below with reference to the accompanying drawings.
[0038] Such as figure 2As shown, the solar hot water supply system of the present invention includes a solar heat collector 10 and a circulating water pump 19, and also includes at least two hot water storage tanks 11 (three hot water storage tanks are used in this embo...

The invention discloses a solar-energy hot water supplying system and its heating method, meanwhile, the invention solves the problem that the prior solar-energy water heater takes use of much assistant heat sources. The solar-energy hot water supplying system comprises a solar-energy collector and a water pump as well as at least two water tanks; a circling water outlet of each water tank is connected with an inlet of the water pump and an outlet of the water pump is connected with the inlet of the solar-energy collector, moreover, the outlet of the solar-energy collector is connected with the circling water returning port of each water tank. The heating method is as follows that each water tank is filled with cool water; water in each water tank is heated by the solar-energy collector to the objective temperature. As the invention is provided with a plurality of water tanks, when solar energy is not enough, water in some water tanks can be heated to the objective temperature by solar energy and water with appropriate temperature can be provided; assistant heat source can be saved. The invention can be used in the hot water concentration supplying system of various public buildings or in family to provide water for life.
Description
Technical field [0001] The present invention involves a system that provides hot water, and specially involves the use of solar energy to heat the water and provide hot water and the heating method of the system. Background technique [0002] In order to meet the needs of social sustainable development, new energy sources must be developed, such as: wind energy, water energy, solar energy, etc.Among them, the use of solar energy has begun to popularize among the general public, and solar water heaters are equipment that popularize and use. [0003] Most solar water heaters are generally used in a hot water tank or multiple connected hot water tanks. During the use process, it is usually that although the water storage water tank is equipped with a thermometer, the supply temperature of the hot water is not limited to limitAs long as there is a demand for hot water, the water tank is used to supply water out. At the same time, as the hot water in the hot water tank decreases, the ...
