Background Art

The shortcomings of the existing solar constant temperature intelligent water supply system are mainly as follows:

3. System complexity and maintenance issues: The solar constant temperature intelligent water supply system involves multiple components, such as collectors, water storage tanks, connection components, control components, etc., which increases the complexity of the system. In addition, since the system is located outdoors, regular maintenance and cleaning are required to ensure the normal operation of the system.

Example 1

As shown in FIG1 , a water circulation constant temperature device for a chemical process pipeline includes a heat preservation water tank 1 and a solar collector 16;

The insulated water tank 1 is connected to the inlet of the solar collector 16 through a low-temperature water pipe 13; a ball valve 14, a heat exchange pump 11 and a check valve 12 are sequentially installed on the low-temperature water pipe 13, and the low-temperature water pipe 13 and the inlet of the solar collector 16 are connected through the ball valve 14; the outlet of the solar collector 16 is connected to the upper position of the insulated water tank 1 through a hot water pipe 17; a breathable valve 15 is installed on the hot water pipe 17;

The low-temperature water pipe 13 and the hot water pipe 17 are both equipped with a temperature sensor 10;

The insulated water tank 1 is provided with a water level sensor 2, and the insulated water tank 1 is provided with a water inlet 4 at the upper position, and a solenoid valve 3 is installed on the water inlet 4;

The thermal insulation water tank 1 is also provided with an electric heater 5, and a sewage outlet 9 is also provided at the lower position of the thermal insulation water tank 1;

The upper and lower positions of the insulated water tank 1 are connected by a circulation pipe 6, on which a pipeline booster pump 7 is provided, and a check valve 12 is installed on the circulation pipe 6 near the bottom of the insulated water tank 1, and a plurality of water outlets for water supply floors are installed on the circulation pipe 6, and a breathable valve 15 is provided between the water outlet for the water supply floor and the pipeline booster pump 7, and a check valve 12 is also connected between the breathable valve 15 and the pipeline booster pump 7 on the circulation pipe 6.

Working principle:

The system uses solar photovoltaic panels to absorb the energy of solar photons and convert it into electrical energy to provide power for system operation. The excess electrical energy is stored in batteries, which provide power for operation when there is insufficient or no light.

Under daylight conditions, the solar energy system automatically circulates temperature differences through the controller. When the water temperature of the solar collector 16 is higher than the water temperature of the insulation water tank 1 by a certain value (generally 8°C, adjustable), the control system automatically starts the heat exchange pump 11, pumps the water with a lower temperature in the insulation water tank 1 into the solar collector 16 for heating, and pushes the hot water with a higher temperature in the solar collector out of the solar collector 16 and flows back to the insulation water tank 1. When the water temperature of the solar collector 16 is higher than the water temperature of the insulation water tank 1 by a certain value (generally 3°C, adjustable), the control system automatically stops the heat exchange pump 11, and the solar collector 16 continues to absorb heat. The heat absorbed by the collector is stored by raising the water temperature of the insulation water tank 1.

(1) Low liquid level protection of thermal insulation water tank 1. When the liquid level of thermal insulation water tank 1 h<H (1 H1 minimum protection liquid level, set to 10cm), the heat exchange pump 11 is started to automatically replenish water until the liquid level of thermal insulation water tank 1 h≥H1 stops.

(2) Temperature difference heat collection cycle. The system adopts a temperature difference heat collection cycle with high heat collection efficiency and low heat loss in the cycle. The solar collector 16 absorbs solar radiation and heats up. When the temperature difference with the water temperature in the insulation water tank 1 is Δt=T (1 T1 pump start temperature difference, set to 8°C), the pipeline booster pump 7 is started to lift the water in the insulation water tank 1 to the solar collector 16 for heating. During the process, the temperature of the solar collector 16 slowly decreases and the water tank temperature slowly increases; when the temperature difference Δt=T (2 T2 pump stop temperature difference, set to 3°C), or the water temperature of the water tank t≥T (3 T3 water tank maximum set temperature, set to 25°C), the pipeline booster pump 7 is stopped, and the solar collector 16 and the water in the water pipe all fall back into the water tank by their own weight.

(3) Constant temperature controlled water replenishment. As the heat collection cycle proceeds, when the temperature of the insulated water tank 1 rises to t≥T4+3 (T4 drinking water temperature, set to 15 °C), the heat exchange pump 11 is started to replenish the water tank until the water tank temperature t≤T4 °C or the water tank liquid level h≥H (2 H2 water tank maximum liquid level, set to 90 cm).

The device uses solar photovoltaic panels to absorb the energy of solar photons and convert it into electrical energy to provide power for system operation. The excess electrical energy is stored in batteries, which provide operating power when there is insufficient or no light.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
