Solar water heating system

Abstract

The invention provides a solar water heating system. The solar water heating system comprises a solar heat collector, a circulating water tank and a heat preservation water tank, wherein a first water inlet of the circulating water tank is connected with a water inlet pipe; a first switching valve is arranged on the water inlet pipe; a first water outlet of the circulating water tank is connected with a circulating pump; a water outlet of the circulating pump is connected with a second water inlet of the circulating water tank through the solar heat collector (1); a second water outlet of the circulating water tank is communicated with the heat preservation water tank through a second switching valve; a water outlet of the heat preservation water tank is connected with a user side through a booster pump; exhaust overflow pipes are arranged at the top of the circulating water tank and the top of the heat preservation water tank; a blowoff valve is arranged at the bottom of the circulating water tank. The solar water heating system fully heats water, is large in heating amount and high in solar energy utilization rate, and can meet water demands of multiple users.

Description

technical field [0001] The invention relates to a water heater, in particular to a solar water heating system. Background technique [0002] With the shortage of energy, solar energy is becoming more and more widespread, and solar water heaters have become an indispensable electrical appliance in production and life. Traditional solar water heaters store water in a small volume, and cannot be reheated when the water is heated to the saturated temperature. The rate is low, and when replenishing while using, hot water mixes with cold water, causing the water temperature to drop, which brings inconvenience to water use, especially in places such as factories and apartment buildings. Contents of the invention [0003] 【1】Technical problems to be solved [0004] The technical problem to be solved by the invention is to provide a solar water heating system with large water supply and high utilization rate of solar energy. [0005] 【2】Technical solution to solve the problem ...
