Large-scale solar water heater

Abstract

The invention provides a large-scale solar water heater which comprises heat collectors and a heat preservation water tank, wherein a water inlet pipe is arranged at the water inlet of each heat collector, a first stop valve and a first filter gate are arranged on the water inlet pipe, the water outlet of each heat collector is connected with the water inlet of a heat preservation water tank through a second stop valve and a second filter gate, the water outlet of the heat preservation water tank is connected with a user end through a third stop valve and a pump, and a temperature sensor is arranged on the heat preservation water tank. In the solar water heating system provided by the invention, a plurality of heat collectors are connected in parallel for heating, the heating effect is good, well heated hot water is placed into the heat preservation water tank for heat preservation, when being required for use by the user end, the heat water can be extracted; moreover, an electric heater is arranged in the heat preservation water tank so as to play an auxiliary effect and prevent the temperature of water inside the heat preservation water tank from being lowered after long time; the solar water heating system provided by the invention can sufficiently heat water, the heating quantity is high, the availability of solar energy is high, and requirements of users for water using can be met.

Description

technical field [0001] The invention relates to a water heater, in particular to a large solar water heater. 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 present invention is to provide a large-scale solar water heater with large water supply and high utilization rate of solar energy. [0005] 【2】Technical solution to solve the p...
