Detailed Description
The present invention will be described in further detail with reference to the following examples:
an energy-saving heat supplementing device for a ground source heat pump system is shown in fig. 1 and comprises a buried pipe 1 arranged underground, a solar heat collecting pipe 5 arranged on the ground and a water tank 6 connected with the solar heat collecting pipe 5 through a water pipe, wherein the water tank 6 is connected with one end of the buried pipe 1 through a first water pipe 8, and the other end of the buried pipe 1 is connected with the solar heat collecting pipe 5 through a second water pipe 2. In this way, automatic heat circulation is formed among the solar heat collecting pipe 5, the water tank 6, the first water pipe 8, the buried pipe 1 and the second water pipe 2 to supplement heat to the soil near the buried pipe 1.
The buried pipe 1 is buried under the ground by 100 meters deeply, the soil heat pump unit 12 is used for collecting the soil heat under the ground by 100 meters in winter to supply heat for users, and in order to ensure that the heating system continuously operates normally all the year round, the heat of the soil near the buried pipe 1 needs to be supplemented in summer, so that the reduction of the working efficiency of the soil source heat pump unit 12 caused by the reduction of the ground temperature is prevented. In summer, water in the solar heat collecting pipe 5 absorbs heat of the sun, the water temperature rises, the water flows in the direction with small resistance due to thermal expansion and flows into the water tank 6, the water in the solar heat collecting pipe 5 is lack of water, the water in the buried pipe 1 automatically supplements the heat of the sun in the solar heat collecting pipe 5 through the second water pipe 2 due to the siphon principle, after the water in the buried pipe 1 flows into the solar heat collecting pipe 5, the water in the buried pipe 1 temporarily lacks water under the action of gravity, the water with the increased temperature in the high-position water tank 6 automatically flows into the buried pipe 1 through the first water pipe 8 to supplement the lack of water in the buried pipe 1, in the process that the water flows into the buried pipe 1 from the water tank 6, the high-temperature water continuously emits heat, the soil around the buried pipe 1 continuously absorbs the heat in the high-temperature water to supplement the heat absorbed by the soil around the heating buried pipe 1 in the previous year, and the process is circulated, the hot water in the water tank 6 is continuously sent to the buried pipe 1 to supplement heat for the underground soil. The automatic heat circulation makes up the heat absorbed from the ground in the last year of heating in summer in non-heating seasons, and ensures that the soil source heat pump unit 12 can normally heat in the winter heating seasons.
In order to ensure that the device can be normally used in winter and summer, a first valve 7, a second valve 3, a third valve 11, a fourth valve 10, a fifth valve 13 and a third water pipe 4 are additionally arranged.
