The heat and heat storage integrated device 12 has a function of heating and storing water by using a circulating medium of the solar heat collector 1 and assisting in heating. The heater for auxiliary heating adopts natural gas or electric heating mode to heat the water tank 3. When the water temperature of the user side pipeline is reduced, the user side circulating pump 203 is started, and low-temperature water enters the water tank 3 through the second input pipe 201 and is mixed with the water of the water tank 3, so that the water supply temperature is constant.
The solar water heating system for the assembled residential building has the following operation modes:
(1) And (5) heat storage operation. The system sets the water outlet temperature of the water tank 3 in the heating and heat storage integrated device 12 to a certain preset value, namely when the second temperature sensor 9 displays a certain temperature, such as 35 ℃, the electric two-way valve 8 arranged on the water inlet pipe 301 is opened, the water inlet end 200 supplements water for the water tank 3, the heat collection circulating pump 6 in the first pipeline assembly 10 is opened, and the solar heat collector 1 continuously and circularly heats the water of the water tank 3.

(2) The water storage tank is operated safely. When the hot water generated by heating of the heat collector 1 is continuously accumulated in the water tank 3 in the heating and heat storage integrated device 12, and when the liquid level meter 4 arranged on the water tank 3 shows that the water in the water tank 3 reaches the highest water level, the electric two-way valve 8 arranged on the water inlet pipe 301 in the third pipeline assembly 30 is closed, the water inlet end 200 stops supplementing water to the water tank 3, and the water in the water tank is continuously heated. Meanwhile, the safety valve 5 arranged on the water tank can prevent the pressure of the system from being too high after the water in the water tank is continuously heated, and the pressure of the system is relieved and protected through the safety valve 5.
(3) And water is quickly supplemented.

(4) Auxiliary heating and water mixing. A certain temperature value, such as 35 degrees celsius, of the second temperature sensor 9 in the second pipeline assembly 20 is set, and when the temperature value is low and the user terminal 100 takes water, the heater on the water tank 3 is turned on, that is, the water in the water tank 3 is heated by the auxiliary heating device, so that the water temperature reaches the preset set temperature of the second temperature sensor 9. When the temperature of the water entering the user side 100 is lower than 33 ℃, the user side circulating pump 203 is started, the water in the second output pipe 202 at the user side flows back to the water storage tank 3 along the second input pipe 201 to mix and heat, and the water supply temperature of the concentrated hot water is constant through the auxiliary heating and water mixing functions.
(5) And (3) freezing prevention. At extreme temperatures at night in winter, when the second temperature sensor 9 in the second line assembly 20 shows that the water temperature is below 5 ℃, the auxiliary heating means in the water tank 3 is turned on and heats the water in the water tank 3. When the second temperature sensor 9 shows that the water temperature is 8 ℃, the system is free from the risk of freezing, and the auxiliary heating device in the water tank 3 can be turned off.
In summary, the solar water heating system for the assembled residential building can effectively adapt to the structural characteristics of the assembled building, meets the requirement of building integration, and has positive energy saving significance and good popularization and application value on the basis of meeting the hot water requirement of a user. The solar water heating system for the assembled residential building realizes concentrated supply of domestic hot water by utilizing solar energy to the greatest extent, and has good energy-saving benefit by heating through the auxiliary heat source when the temperature is low.
