Solar hot water supply system and heating means thereof

Abstract

The invention discloses a solar hot water supply system and a heating method thereof, which solves the problem that the existing solar water heaters use many auxiliary heat sources. The solar hot water supply system includes a solar heat collector and a water pump, and also includes at least two water tanks, the circulating water outlet of each water tank is connected to the inlet of the water pump, and the outlet of the water pump is connected to the inlet of the solar heat collector, The outlet of the solar heat collector is connected to the water circulation return port of each water tank. The heating method is as follows: each water tank is poured into cold water; the water in each water tank is sequentially heated to the target temperature through the solar collector. Because a plurality of water tanks are arranged, when solar energy is not sufficient, solar energy can be used to heat the water in part of the water tanks to the target temperature, so as to provide water with a suitable temperature, and the auxiliary heat source is saved. The invention can be used in centralized hot water supply systems of various public buildings, and can also be used in households to provide domestic water.

Description

technical field [0001] The invention relates to a system for providing hot water, in particular to a system for heating water with solar energy to provide hot water, and a heating method for the system. Background technique [0002] In order to meet the needs of sustainable social development, it is necessary to develop new energy sources that can be used sustainably, such as wind energy, water energy, and solar energy. Wherein the utilization of solar energy has begun to popularize among the general public, and solar water heaters are exactly the equipment of popularizing utilization. [0003] Most solar water heaters now generally use one hot water storage tank or multiple connected hot water storage tanks. During use, it is usually the case that although the hot water storage tanks are equipped with thermometers, there is no limit to the supply temperature of hot water. , as long as there is a demand for hot water, the hot water storage tank will supply water to the outs...

Problems solved by technology

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
