Description

A new type of water circulation instant solar water heater system

technical field

The invention relates to a novel water circulation instant solar water heater system, which belongs to the field of solar energy utilization.

Background technique

Today, solar water heaters have entered thousands of households to provide people with domestic hot water. But when in use, the cold water in the pipeline connecting the faucet and the water heater storage tank is released from the faucet first. After the cold water is discharged, the hot water in the storage tank can be released. This is what people often say about solar water heaters. "question. Because the connecting pipe between the water heater and the indoor control valve is generally not insulated, so after the water valve is closed, the water in the pipe stops flowing, the heat of the water will be lost quickly, and the temperature will drop rapidly. Usually, the temperature in the pipe will be the same as the environment after ten minutes The temperature is the same, and the lower the ambient temperature, the faster the temperature of the water in the pipeline will drop. When using water again, it is still necessary to release the cold water in the pipeline to have hot water. This causes a great waste of water resources. For large-scale solar water heaters used in multiple rooms, the connecting pipes used are longer, and the amount of water stored therein is larger, resulting in more serious waste of water resources.

The use of solar water heaters has obvious seasonality. The hot water production effect is better in summer and autumn, but in winter, due to the low temperature, the pipes connecting the solar water heaters and indoor valves are easily frozen, making the solar water heaters unusable. Users often need to In addition, water heaters are purchased to ensure the use of hot water in winter, which increases additional expenses.

The methods for solving the above problems in the prior art mainly include the following types. One is to use thermal insulation material to wrap the pipeline, which has a certain effect but the thermal insulation effect is not good, and the heat of the water in the pipeline is still lost quickly; the second is to use electric heating cables to cover the entire outdoor pipeline, and energize the electric heating cables to achieve pipeline insulation , power consumption. These two methods are passive heat preservation, and as time prolongs, the above-mentioned heat preservation materials will all age in varying degrees, consume electric energy, and have poor heat preservation effect.

The third is to combine the above two methods and adopt the method of pipeline circulation at the same time, which is to install a circulating water pipe in the solar water heater, and install a circulating pump between the water pipes to make the water in the pipeline and the water in the storage tank circulate to achieve the heat preservation effect. The method can be used in places with large-scale water use such as hotels. Due to the relatively large demand for hot water, the relative cost of electric energy consumed by the circulating pump is acceptable, but it is still not environmentally friendly to simply consume electric energy to drive the cycle; this method is especially not It is suitable for household solar water heaters, because domestic solar water heaters use relatively little hot water and cannot form a large-scale use of hot water. The method of using electric energy to drive circulating pumps to drive hot water circulation is not cost-effective and does not have the universality of popularization and application. .

Contents of the invention

The purpose of the present invention is to solve the deficiencies in the prior art, and provide a new type of self-driven water circulation instant solar water heater system that does not require or requires a small amount of external power such as electric energy.

The first water pipe, the second water pipe and the water storage tank can form a circulation circuit. When the user does not use water, the hot water in the water storage tank circulates in the circuit driven by the impeller. When the user uses hot water, open the three-way valve to release it. hot water.

When working, the heat collecting tube bundle absorbs the radiant heat of the sun, produces hot water and stores it in the water storage bucket. The three-way valve of the regulating device can realize that the user releases hot water, supplies water to the solar water heater, and makes the first water pipe, the second water pipe and the water storage bucket form a communication circuit. The auxiliary heat collecting tube absorbs solar energy to produce hot water and store it in the auxiliary water storage tank. The hot water in the auxiliary water storage tank is the heating tube, the displacement piston, the first connecting rod, the crank, the connecting pipe, the cooling pipe, the power piston, the second The driving device composed of connecting rods provides the driving force, drives the impeller to rotate, and drives the hot water in the water storage tank to flow in the circuit, so as to provide hot water for users at any time.

Compared with the prior art, the present invention has outstanding substantive features and significant progress: the second water pipe is set separately from the first water pipe, and a closed circuit can be formed through the adjustment of the three-way valve, which increases the consumption of no electric energy or a small amount of The impeller that consumes electric energy drives the hot water circulation in the closed circuit, which can provide users with hot water at any time, which not only avoids the process of putting cold water before the existing solar water heater is used, saves water resources, but also realizes the full use of solar energy , to ensure the normal use of solar water heaters throughout the year, especially in winter. Lower operating costs than purely electric water pumps moving water. It can be seen that the novel water circulation instant solar water heater system proposed by the present invention, which requires no or less external power, has significant substantive features and beneficial effects.

Wherein, the gas in the sealed cavity of the heating pipe 11 and the cooling pipe 15 is air.

When the water heater system is in operation, the heat collecting tube bundle 2 absorbs the radiant heat of the sun to produce hot water and store it in the water storage tank 1 . Through the three-way valve 5 in the adjustment device, the first water pipe 4 can be connected with the hot water outlet pipe 6, the first water pipe 4 and the second water pipe 8, and the second water pipe 8 and the cold water inlet pipe 7 respectively, and respectively realize the following three Two functions: the user releases hot water; makes the first water pipe 4, the second water pipe 8 and the water storage bucket 1 form a circuit; supplies water to the solar water heater. When the user releases hot water, the three-way valve 5 in the adjustment device makes the first water pipe 4 communicate with the hot water outlet pipe 6, and hot water is released directly. Close the three-way valve 5, so that the first water pipe 4, the second water pipe 8 and the water storage tank 1 form a circuit. At this time, the auxiliary heat collecting pipe 9 absorbs the radiant heat of solar energy to prepare hot water and stores it in the auxiliary water storage tank 10. The hot water in the bucket 10 transmits heat to the heating tube 11, and the air in the left chamber of the heating tube 11 is heated and expands, pushing the displacement piston 12 to move to the right, pushing the first connecting rod 13 to drive the crank 14 to rotate; at the same time, the displacement piston 12 The air in the right cavity is compressed and flows along the connecting pipe 18 to the cooling pipe 15, pushing the power piston 16 to move to the right, pushing the second connecting rod 17 to drive the crank 14 to rotate; the power piston 16 in the cooling pipe 15 is moving to the right , the volume of the left chamber of the cooling pipe 15 increases.
