Technical Field

[0001] This utility model belongs to the technical field of heating devices, specifically, it relates to a PVT heat pump heating device. Background Technology

[0002] With the increasing prominence of the energy crisis and environmental problems, the demand for clean energy and efficient heating equipment is becoming more and more urgent. Traditional heating methods, such as boiler heating using coal and natural gas as fuels, suffer from low energy utilization and serious environmental pollution. Solar energy, as a clean energy source, is constantly evolving in its utilization methods; however, simple solar photovoltaic (PV) systems can only convert solar energy into electricity, and the temperature rise of photovoltaic cells during operation affects power generation efficiency. While traditional heat pump systems can increase heat output, they require the consumption of electricity to extract heat from the environment. PVT systems, which combine solar photovoltaic technology with heat pump technology, suffer from low heat exchange efficiency, complex structure, and insufficient overall heating stability. Therefore, an improved PVT heat pump heating device is needed to meet the demand for efficient and stable heating.

[0003] To address these issues and shortcomings, the inventors have proposed a PVT heat pump heating device. Utility Model Content

[0004] To address the technical problems of low heat exchange efficiency, complex structure, and insufficient overall heating stability in PVT systems that combine solar photovoltaic technology and heat pump technology, the basic concept of this utility model is as follows:

[0005] A PVT heat pump heating device includes an insulated shell, a heat pump, and an intelligent controller. The insulated shell has an internal receiving groove, and a photovoltaic cell is fixedly installed inside the receiving groove. A heat-absorbing plate is fixedly installed on the back of the photovoltaic cell. The heat-absorbing plate has an internal pipe groove, and a first heat pipe is fixedly sleeved inside the pipe groove. A first flow regulating valve is fixedly connected to the inlet and outlet of the lower end of the first heat pipe. A heat insulation sleeve is fixedly connected to the lower end of the insulated shell, and the heat insulation sleeve is fixedly sleeved to the lower end of the first heat pipe. An environmental detector is fixedly installed on the upper end of the insulated shell.

[0006] In a preferred embodiment of this utility model, a heat-absorbing fin is fixedly connected to the upper back of the heat-absorbing shell, a second heat pipe is fixedly sleeved inside the heat-absorbing fin, and a second flow regulating valve is fixedly connected to the lower inlet and outlet of the second heat pipe.

[0007] In a preferred embodiment of this utility model, the lower ends of the first flow regulating valve and the second flow regulating valve are respectively fixedly connected to an output pipe and an input pipe. The other end of each output pipe is fixedly connected to the bottom of the heat pump. A compressor is fixedly installed at the upper end of the heat pump, and the interior of the compressor is connected to the interior of the heat pump.

[0008] In a preferred embodiment of this utility model, a pumping pipe is fixedly connected to the upper output port of the compressor, and a third heat pipe and a fourth heat pipe are fixedly connected to the other end of the pumping pipe, and heat dissipation fins are fixedly sleeved on the outside of the third heat pipe and the fourth heat pipe.

[0009] In a preferred embodiment of this utility model, the other ends of the third heat pipe and the fourth heat pipe are respectively fixedly connected to the other end of the input pipe.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention, through the synergistic operation of improved photovoltaic and heat exchange components and a heat pump system, achieves a higher overall energy utilization efficiency compared to traditional PVT heat pump heating devices.

[0021] 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.

[0022] like Figures 1 to 5 As shown, a PVT heat pump heating device includes an insulated shell 1, a heat pump 12, and an intelligent controller 3. The insulated shell 1 has an internal receiving groove, and a photovoltaic cell 2 is fixedly installed inside the receiving groove. A heat-absorbing plate 9 is fixedly installed on the back of the photovoltaic cell 2. A pipe groove is opened inside the heat-absorbing plate 9, and a first heat pipe 10 is fixedly sleeved inside the pipe groove. A first flow regulating valve 7 is fixedly connected to the inlet and outlet of the lower end of the first heat pipe 10. A heat insulation sleeve 8 is fixedly connected to the lower end of the insulated shell 1, and the heat insulation sleeve 8 is fixedly sleeved on the lower end of the first heat pipe 10. An environmental detector 19 is fixedly installed on the upper end of the insulated shell 1.

[0023] In this setup, the photovoltaic and heat exchange components are installed in a sunny location, such as the roof or south facade of a building, ensuring that their installation angle and orientation can maximize the reception of sunlight; the pipes are all wrapped with thermal insulation cotton to prevent heat loss, and the environmental detector 19 includes a light sensing module and a temperature sensor.

[0024] like Figures 1 to 5As shown, in a specific embodiment, a heat-absorbing fin 5 is fixedly connected to the upper back of the heat-absorbing shell 1. A second heat pipe 11 is fixedly sleeved inside the heat-absorbing fin 5. A second flow regulating valve 6 is fixedly connected to the lower inlet and outlet of the second heat pipe 11. An output pipe 13 and an input pipe 17 are fixedly connected to the lower ends of the first flow regulating valve 7 and the second flow regulating valve 6, respectively. The other end of the output pipe 13 is fixedly connected to the bottom of the heat pump 12. A compressor 16 is fixedly installed at the upper end of the heat pump 12, and the interior of the compressor 16 is connected to the interior of the heat pump 12. A pumping pipe 18 is fixedly connected to the upper output port of the compressor 16. A third heat pipe 14 and a fourth heat pipe 15 are fixedly connected to the other end of the pumping pipe 18, respectively. Heat dissipation fins 4 are fixedly sleeved on the outside of the third heat pipe 14 and the fourth heat pipe 15.

[0025] In this setup, when there is sufficient sunlight, the light sensor module in the environmental detector 19 detects that the sunlight intensity has reached a certain threshold, and the photovoltaic cells begin to generate electricity efficiently. Simultaneously, the photovoltaic cells 2 absorb solar radiation, causing their temperature to rise. This heat is transferred to the evaporator of the heat pump system 12 via heat pipes. In the evaporator, the refrigerant absorbs heat and evaporates, becoming a gaseous state that enters the compressor 16. The compressor 16, according to instructions from the control system, compresses the gaseous refrigerant at an appropriate speed, increasing its temperature and pressure. The high-temperature, high-pressure refrigerant then enters the third and fourth heat pipes, releasing heat to the heat dissipation fins 4, thus providing heating. During this process, the control system (intelligent controller 3) adjusts the opening of the electronic expansion valve based on data from the temperature sensor to ensure the stable operation of the heat pump system. Simultaneously, it controls the amount of heat supplied through a flow regulating valve according to the needs of the heat dissipation fins 4.

[0026] like Figures 1 to 5 As shown, in a specific embodiment, the other ends of the third heat pipe 14 and the fourth heat pipe 15 are fixedly connected to the other end of the input pipe 17, respectively; the intelligent controller 3 is electrically connected to the photovoltaic cell 2, the compressor 16, the first flow regulating valve 7, the second flow regulating valve and the environmental detector 19, and the photovoltaic cell 2 is electrically connected to the compressor 16.

[0027] In this setup, when the light intensity decreases, the light sensor module transmits a signal to the control system (intelligent controller 3). Based on data from the temperature sensor, the control system adjusts the opening of the flow regulating valve, increasing the proportion of heat absorbed from the environment by the second-stage evaporator (second heat pipe 11). The compressor 16 automatically adjusts its speed according to the system's total heat demand and the heat source temperature, maintaining the heating capacity of the heat pump 12 system. This ensures a stable supply of heat to the heat dissipation fins 4 even when solar energy is insufficient. Through these steps, this PVT heat pump heating device can achieve efficient and stable heating under different environmental conditions.

[0028] The implementation principle of a PVT heat pump heating device in this embodiment is as follows:

[0029] When using this equipment, the photovoltaic and heat exchange components should be installed in a sunny location, such as the roof or south facade of a building, ensuring that their installation angle and orientation can receive sunlight to the maximum extent. The pipes are all wrapped with thermal insulation cotton to prevent heat loss, and the environmental detector 19 includes a light sensing module and a temperature sensor.

[0030] When there is sufficient sunlight, the light sensor module in the environmental detector 19 detects that the sunlight intensity has reached a certain threshold, and the photovoltaic cells begin to generate electricity efficiently. Simultaneously, the photovoltaic cells 2 absorb solar radiation and their temperature rises. This heat is transferred to the evaporator of the heat pump system 12 via heat pipes. In the evaporator, the refrigerant absorbs heat and evaporates, becoming a gaseous state that enters the compressor 16. According to the instructions of the control system, the compressor 16 compresses the gaseous refrigerant at an appropriate speed, increasing its temperature and pressure. The high-temperature, high-pressure refrigerant enters the third and fourth heat pipes, releasing heat to the heat dissipation fins 4, thus providing heating. During this process, the control system (intelligent controller 3) adjusts the opening of the electronic expansion valve based on data from the temperature sensor to ensure the stable operation of the heat pump system. At the same time, it controls the amount of heat supplied through the flow regulating valve according to the needs of the heat dissipation fins 4.

[0031] When the light intensity decreases, the light sensor module transmits a signal to the control system (intelligent controller 3). Based on the data from the temperature sensor, the control system adjusts the opening of the flow regulating valve, increasing the proportion of heat absorbed from the environment by the second-stage evaporator (second heat pipe 11). The compressor 16 automatically adjusts its speed according to the total heat demand of the system and the heat source temperature, maintaining the heating capacity of the heat pump 12 system. This ensures that heat can still be stably provided to the heat dissipation fins 4 even when solar energy is insufficient. Through these steps, this PVT heat pump heating device can achieve efficient and stable heating under different environmental conditions.
