Description

A solar water heater pipeline cold water removal device

technical field

The utility model relates to a cold water removal device for solar water heater pipelines, in particular to a cold water removal device for residential solar water heater pipelines, which belongs to the technical field of energy saving.

Background technique

At present, with the continuous reduction of global resources, the development of some new renewable energy sources has become more and more important. Solar energy, as a relatively safe, easy-to-develop, and potential non-polluting clean energy, has received many attentions. The solar hot water pipeline is more than ten meters long, and the cold water in the pipeline needs to be drained before each use, which wastes a lot of water. The utility model adopts a pipeline cold water removal device. The pipeline is empty when not in use at ordinary times. When in use, hot water will flow out directly from the solar heat preservation box. After use, there will be hot water in the solar pipeline. No one uses the hot water until it drops to the set temperature, and the residual hot water in the pipeline returns to the solar incubator through another pipeline, thus ensuring that water resources are not wasted. Since the solar pipeline is empty for a long time when hot water is not used, this device simultaneously solves the freezing problem of the solar pipeline in winter, thereby reducing some expenses on antifreezing devices.

Utility model content

The purpose of the utility model is to provide a device for removing cold water in solar pipelines. The device solves the problem of removing cold water in solar pipelines. The device is installed on the original solar water heater, so that the solar water heater saves water and prevents freezing, and is more convenient to use. A device that is energy-saving and convenient.

The technical scheme of the utility model is:

A solar water heater pipeline cold water removal device, comprising a cold water return pump, a solar heat preservation box, an exhaust pipe, a hot water outlet valve, a hot water outlet pipe, a water outlet valve and a return pipe, and a hot water outlet is provided at the outlet below the solar heat preservation box The valve is connected to the hot water outlet pipe through the hot water outlet valve. The water outlet valve is connected under the hot water outlet pipe. One end of the cold water return pump is connected to the solar incubator, and the other end is connected to the return pipe. The outlet pipe is connected, the lower end of the exhaust pipe is connected to the hot water outlet pipe, and the upper end is directly communicated with the atmosphere.

Beneficial effects of the utility model: the utility model solves the problem of removing cold water in the solar pipeline, has a simple structure, is economical and practical, not only solves the freezing problem of the solar pipeline in winter, but also saves water resources.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Accompanying drawing is the overall installation figure of the utility model.

In the figure: 1. Cold water return pump, 2. Solar thermal insulation box, 3. Exhaust pipe, 4. Hot water outlet valve, 5. Hot water outlet pipe, 6. Water outlet valve, 7. Return pipe.

Detailed ways

A solar water heater pipe cold water removal device, comprising a cold water return pump 1, a solar heat preservation box 2, an exhaust pipe 3, a hot water outlet valve 4, a hot water outlet pipe 5, a water outlet valve 6 and a return pipe 7, and a solar heat preservation box 2 The outlet below is provided with a hot water outlet valve 4, and is connected with the hot water outlet pipe 5 through the hot water outlet valve 4, the water outlet valve 6 is connected below the hot water outlet pipe 5, and one end of the cold water return pump 1 is connected to the solar insulation box 2, and the other is connected to the hot water outlet pipe 5. One end is connected to the return pipe 7, the return pipe 7 is connected to the hot water outlet pipe 5 at the water outlet valve 6, the lower end of the exhaust pipe 3 is connected to the hot water outlet pipe 5, and the upper end is directly communicated with the atmosphere.

When using hot water, open the hot water outlet valve 4, hot water flows out from the solar thermal insulation box 2, open the water outlet valve 6, and the hot water flows out through the water outlet valve 6. When the hot water is stopped, close the water outlet valve 6 and the hot water outlet valve 4. At this time, a tube of hot water remains in the hot water outlet pipe 5 and the return pipe 7 and cannot be discharged normally. When the hot water in the pipeline is lower than the set temperature , the cold water return pump 1 starts to work, the cold water flows back to the solar incubator 2 through the return pipe 7, and the cold water return pump 1 is closed. When using hot water again, repeat the above operations, and another working cycle begins.
