Description

Technical Field

[0001] This utility model belongs to the field of heating technology, specifically, it relates to a heating system that combines non-powered solar energy and ground source heat pump. Background Technology

[0002] Ground source heat pump systems are widely used due to their cleanliness and efficiency. A typical system consists of outdoor buried pipe heat exchange, ground source heat pump heat energy conversion, and indoor terminal circulation, which can provide heating, cooling, and domestic hot water supply.

[0003] However, long-term heat extraction in northern regions has led to a decrease in geothermal temperature and a reduction in heat supply, resulting in significant differences in heat balance rates across different regions. Consequently, geothermal temperatures in northern regions are decreasing and heat supply is becoming increasingly scarce.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the technical problem that long-term heat extraction in northern regions leads to decreased geothermal temperatures and reduced heat supply, resulting in significant differences in heat balance rates across different regions and consequently, increasingly lower geothermal temperatures and less heat in northern areas, the basic concept of this utility model is as follows: A heating system combining non-powered solar energy and ground source heat pump includes a non-powered solar energy source, a buried pipe, a ground source heat pump host, a water heater, a smart interconnected control device, and heating terminal components. The non-powered solar energy source is connected to a solar thermal storage device through a pipeline, and the solar thermal storage device is connected to the ground source heat pump host. The buried pipe is connected to the ground source heat pump host and provides a heat source for the ground source heat pump host. The ground source heat pump host is connected to a heating terminal component. The intelligent interconnected control equipment is used to control the operation of the non-powered solar energy and ground source heat pump main unit and various system components.

[0006] In a preferred embodiment of this utility model, the heating terminal assembly includes heat sinks, fan coil units, and underfloor heating coils.

[0007] In a preferred embodiment of this utility model, the water heater is connected to a shower head to realize the terminal supply of domestic hot water.

[0008] In a preferred embodiment of this utility model, a cold water pipe is connected to the outside of the non-powered solar energy source, and the end of the cold water pipe away from the non-powered solar energy source is connected to a water heater to provide cold water to the system.

[0009] In a preferred embodiment of this utility model, the non-powered solar energy is a solar thermal collector device consisting of multiple sets connected in parallel.

[0010] As a preferred embodiment of this utility model, the intelligent interconnected control device can automatically adjust the operating mode of the non-powered solar and ground source heat pump units according to the ambient temperature, solar irradiance intensity and user needs.

[0011] In a preferred embodiment of this utility model, the smart interconnected control device is connected to a BIPV, which provides power for the system operation.

[0012] Compared with the prior art, the present invention has the following advantages: In this invention, solar energy directly participates in heating without the need for power, which can share the heat extraction load of the ground source heat pump from the buried pipe, reduce the excessive extraction of geothermal energy, effectively alleviate the problem of reduced geothermal temperature and reduced heat supply caused by the continuous extraction of geothermal energy when the ground source heat pump is used alone for a long time in northern regions, maintain the stability of the underground thermal environment, and ensure the long-term and efficient heating capacity of the ground source heat pump.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0017] like Figures 1 to 2As shown, a heating system combining non-powered solar energy and ground source heat pump includes a non-powered solar energy source 1, a buried pipe 6, a ground source heat pump host 7, a water heater 3, a smart interconnected control device 12, and heating terminal components. The non-powered solar energy source 1 is connected to a solar thermal storage device 5 through a pipeline. The solar thermal storage device 5 is connected to the ground source heat pump host 7. The buried pipe 6 is connected to the ground source heat pump host 7 to provide a heat source for heat exchange. The ground source heat pump host 7 is connected to the heating terminal components. The smart interconnected control device 12 is used to control the operation of the non-powered solar energy source 1, the ground source heat pump host 7, and the various components of the system.

[0018] Furthermore, the heating terminal components include radiator 8, fan coil unit 9, underfloor heating coil 10, and water heater 3 is connected to shower head 4 to realize the terminal supply of domestic hot water.

[0019] Furthermore, a cold water pipe 2 is connected to the outside of the non-powered solar cell 1. The end of the cold water pipe 2 away from the non-powered solar cell 1 is connected to the water heater 3 to provide cold water to the system. The non-powered solar cell 1 is a solar thermal collector device with multiple sets connected in parallel.

[0020] Furthermore, the intelligent interconnected control device 12 can automatically adjust the operating mode of the non-powered solar panel 1 and the ground source heat pump host 7 according to the ambient temperature, solar irradiance intensity and user needs. The intelligent interconnected control device 12 is connected to a BIPV 11, which provides power for the system operation.

[0021] The implementation principle of a heating system combining non-powered solar energy and ground source heat pump in this embodiment is as follows: First, the buried pipe 6, which is buried 100 to 150 meters underground, forms a circulation with the ground source heat pump host 7. The buried pipe 6 provides heat (in winter heating scenarios) or cooling (in summer cooling scenarios) to the ground source heat pump host 7 with the help of the stable thermal environment of the soil. The ground source heat pump host 7 extracts and converts this energy. At the same time, the non-powered solar energy 1 is used to collect solar energy and transfer the heat to the solar thermal storage device 5 for energy storage. Next, the ground source heat pump unit 7 and the solar energy storage device 5 work together to transport heat to various heat dissipation terminals through pipelines: heat can be dissipated through convection by the heat sink 8, or through air circulation driven by the fan coil unit 9 to complete heat exchange, or through the underfloor heating coil 10 to dissipate heat evenly into the room by radiation heat exchange, to meet the heating needs of different scenarios.

[0022] In terms of domestic hot water supply, cold water enters the water heater 3 through the cold water pipe 2 and is heated by the heat in the system (provided by solar energy or ground source heat pump). The heated water provides domestic hot water support for showering.

[0023] Furthermore, BIPV11 (Building Integrated Photovoltaics) converts solar energy into electrical energy to power the equipment within the system; the intelligent interconnected control device 12 intelligently regulates the entire system, covering the heat collection efficiency of the non-powered solar energy 1, the energy storage rhythm of the solar thermal storage device 5, the operating status of the ground source heat pump host 7, as well as the working modes of the radiator 8, fan coil unit 9, and underfloor heating coil 10, and the heating process of the water heater 3, thereby achieving efficient allocation and coordinated operation of the entire system's energy; in this way, the non-powered solar energy 1 can directly participate in heating, reducing excessive extraction of geothermal energy, effectively alleviating the problem of reduced geothermal temperature and reduced heat supply caused by continuous heat extraction when using the ground source heat pump 7 in northern regions for a long time, thereby maintaining the stability of the underground thermal environment and ensuring the long-term efficient heating capacity of the ground source heat pump.
