[0029] The third connecting pipe 104 is fixedly installed with a valve 105. The valve 105 is located at the connecting position of the third connecting pipe 104 and the hot water supply pipe 103. The valve 105 mainly plays a role in controlling the hot water circulation path. By opening and closing the valve 105, whether the hot water enters the circulation can be adjusted.

Through the multi-layer structure, the heat loss of the entire pipe system during the transmission of hot water is greatly reduced, which helps to improve the overall energy-saving efficiency of the system.

[0034] Working principle:

[0035] Cold water enters the solar collector 2 through the cold water supply pipe 201, and the solar collector 2 heats the cold water using solar energy. In the case of sufficient sunlight, the absorption device in the collector converts solar radiation energy into heat energy, causing the temperature of the water to rise. The heated hot water flows into the pressure storage water tank 1 through the first connecting pipe 101 for storage. After the hot water enters the pressure storage water tank 1, it will gather at the upper part of the tank due to its lower density. As the hot water enters the pressure storage water tank 1, the cold water at the bottom of the tank is sucked into the solar collector 2 through the second connecting pipe 102 for re-heating. This is a natural circulation process that relies on the density difference between hot and cold water, without the need for additional power equipment, achieving energy saving and environmental protection.

[0036] Through the cooperation of the third connecting pipe 104 and the first circulating pump 106, a hot water circulation path is established, allowing hot water to circulate between the pressure storage water tank 1 and the hot water supply pipe 103, ensuring that the hot water maintains a suitable temperature in the pipeline, reducing the time users wait for hot water and the waste caused by cold water discharge.

[0037] When the light is insufficient, the temperature sensor 4 detects that the water temperature in the pressure storage water tank 1 is insufficient, and transmits a signal to the controller. The controller controls the air energy heat pump 3 to operate, and the fourth connecting pipe 301 connected to the air energy heat pump 3 draws water from the pressure storage water tank 1, heats it using the heat energy in the air, and then sends the hot water back to the tank through the fifth connecting pipe 302. The second circulating pump 303 is installed on the fourth connecting pipe 301 to provide power for the circulation of water between the air energy heat pump 3 and the tank, ensuring smooth heat transfer. When the solar heat is insufficient, the water in the pressure storage water tank 1 is further heated to ensure normal hot water supply.

[0038] During the hot water circulation and delivery process in the building's water supply and drainage system, the output pipe body 6 made of polyurethane insulation pipe can effectively reduce the heat loss of hot water during transmission in the pipeline. The ceramic-based thermal barrier coating on the outer wall of the polyurethane insulation pipe serves as the thermal barrier layer 7, further reducing the rate of heat conduction through the pipe wall to the outside, enhancing the thermal insulation effect of the pipeline. The outer layer of aerogel blanket serves as the insulation layer 8, which has a low thermal conductivity and can maximize the prevention of heat dissipation to the external environment. Through the multi-layer structure, the heat loss of the entire pipeline system during hot water transmission is greatly reduced, which helps to improve the overall energy efficiency of the system.
