Description

Technical Field

[0001] This utility model belongs to the field of solar thermal and photovoltaic utilization, and relates to a solar CPV / T heat pump energy storage integrated energy supply system. Background Technology

[0002] In practical engineering applications, commercial PV / T heat pump systems often involve long connecting pipes between the main unit and the PV / T modules. In northern regions during winter, this can easily lead to excessively high compression ratios in heating mode, resulting in increased compressor load, reduced efficiency, and increased power consumption. Furthermore, the elevated internal temperature on the high-pressure side affects refrigerant performance and may cause a decrease in lubricating oil viscosity, reducing its lubricating effect and increasing the likelihood of compressor wear. As operating time increases, lubricating oil accumulates in the system, potentially damaging the compressor due to insufficient lubrication. Direct expansion PV / T heat pump systems connect the air source heat exchanger and PVT modules in series, making the system more susceptible to environmental influences.

[0003] Non-direct expansion concentrating CPV / T systems can achieve high hot water temperatures after the components are in operation, but the system is limited to heating and power generation in extremely cold regions and cannot well meet cooling needs, thus limiting its application in diversified and comprehensive energy supply.

[0055] Please see Figure 1 This is a solar CPV / T heat pump energy storage integrated energy supply system, comprising the following five subsystems:

[0056] The CPV / T solar collector system consists of CPV / T photovoltaic modules 1, ethylene glycol circulation pump 6, replenishment pump 7, solar thermal heat exchanger 10, piping, valves, etc. The CPV / T photovoltaic modules 1 not only generate electricity but also absorb solar energy and convert it into heat energy through their hot surfaces. Ethylene glycol, as the heat exchange medium, circulates between the CPV / T photovoltaic modules 1 and the solar thermal heat exchanger 10, driven by the ethylene glycol circulation pump 6, transferring heat energy to the domestic hot water supply system. The replenishment pump 7 is used to replenish the medium loss in the ethylene glycol circulation loop or to periodically adjust the concentration of the circulating coolant in the CPV / T solar collector system. Two sets of ethylene glycol circulation pump 6 are provided as backups. Furthermore, the CPV / T solar collector system is coupled to the CPV / T power system through the CPV / T modules 1 and to the domestic hot water supply system through the solar thermal heat exchanger 10.

[0057] The CPV / T power system consists of an inverter (2), a grid-connected box (3), an electrochemical energy storage device (4), a distribution box (5), and power cable equipment. The inverter (2) converts the direct current (DC) generated by the CPV / T photovoltaic modules (1) into alternating current (AC), which is then connected to the power grid via the grid-connected box (3) or supplied to local loads. The electrochemical energy storage device (4) stores off-peak electricity from the grid or excess electrical energy generated by the CPV / T photovoltaic modules (1).

[0058] The domestic hot water supply system consists of a domestic water tank 8, a domestic cold water pump 9, a solar thermal heat exchanger 10, a heat pump heat exchanger 11, an energy storage tank 12, a domestic hot water pump 13, piping, valves, etc. The domestic water tank 8, domestic cold water pump 9, energy storage tank 12, and domestic hot water pump 13 are connected sequentially. The outlet of the domestic hot water pump 13 is connected to the outlet of the domestic cold water pump 9. The domestic cold water pump 9 delivers cold water from the domestic water tank 8 to the solar thermal heat exchanger 10 for initial heating, then further heats it through the heat pump heat exchanger 11, and finally stores it in the energy storage tank 12. The energy storage tank 12 is equipped with an electric heater for heating the water in it. When hot water is needed, the domestic hot water pump 13 delivers hot water to the user. Furthermore, the domestic hot water supply system is coupled to the heat pump supply system through the heat pump heat exchanger 11.

[0059] The heat pump energy supply system comprises a heat exchanger 14, a heat pump heat exchanger 11, an indoor heat exchanger 19, a first throttling element 15, a second throttling element 16, a compressor 17, and a four-way valve 18. This system uses heat pump circulation to raise the temperature of heat energy from the domestic hot water supply system or the external environment to a higher level for heating or cooling on the user side. The four-way valve 18 is used to switch between the system's heating and cooling modes. Two solenoid valves are installed on the connecting pipe between the heat pump heat exchanger 11 and the heat exchanger 14. One end of the second throttling element 16 is connected between the two solenoid valves, and the other end is connected to the outlet of the first throttling element 15. A solenoid valve is also installed on the connecting pipe between the second throttling element 16 and the inlet of the heat pump heat exchanger 11. The circulation path of the medium is switched by controlling the opening and closing of each solenoid valve. Furthermore, the heat pump energy supply system is coupled to the user-side energy supply system through the indoor heat exchanger 14, which can be an air-source, water-source, or geothermal heat exchanger.

[0060] The user-side energy supply system consists of an indoor heat exchanger 19, an indoor heat exchange circulation pump 20, heat dissipation terminals 21, piping, and valves. The indoor heat exchanger 19, indoor heat exchange circulation pump 20, and heat dissipation terminals 21 are connected by pipes to form a loop. The indoor heat exchange circulation pump 20 transfers the heat generated by the heat pump system to the heat dissipation terminals 21, such as underfloor heating and fan coil units, through the indoor heat exchanger 19, providing users with a comfortable indoor environment. Two sets of indoor heat exchange circulation pumps 20 serve as backups for each other.

[0061] In some optional implementations, the CPV / T photovoltaic module 1 is a concentrating PV / T module with an irradiance of 1000W / ㎡ and an ambient temperature of 25℃, and an overall photothermal and photovoltaic efficiency of not less than 70%.

[0062] In some alternative implementations, the solar thermal heat exchanger, the heat pump heat exchanger, and the energy storage tank are all equipped with bypass pipes, which are connected in parallel at both ends of the solar thermal heat exchanger, the heat pump heat exchanger, and the energy storage tank, respectively.

[0063] In some optional implementations, the heat exchange medium of the CPV / T heat collection system is ethylene glycol, the heat exchange medium of the domestic hot water supply system is domestic water, and the heat exchange medium of the heat pump supply system is one of Freon, R22, R410A, or other refrigerants.

[0064] This utility model provides a solar CPVT heat pump energy storage integrated energy supply system with the following multiple functions:

[0065] CPV / T Solar Collection and Power Generation: Under the irradiation of sunlight, the CPV / T photovoltaic module 1 generates both electrical and thermal energy. The electrical energy is converted into alternating current by the inverter 2 and supplied to the power grid or local load; the thermal energy is transferred to the solar thermal heat exchanger 10 via the glycol circulation pump 6.

[0066] Domestic hot water heating: Ethylene glycol releases heat energy in the photothermal heat exchanger 10 to heat the domestic water. The heated domestic water is selectively further heated by the heat pump heat exchanger 11 and finally stored in the energy storage tank 12.

[0067] Heat pump energy supply and user-side heating: In heating mode, the heat pump energy supply system raises the heat energy in domestic hot water or the heat energy in the external environment to a higher temperature through the regulation of compressor 17 and four-way valve 18, and provides heating services to users through indoor heat exchanger 19 and heat dissipation terminal 21.

[0068] System monitoring and maintenance: The system is equipped with monitoring equipment to monitor the working status and performance parameters of each component in real time. When a fault occurs or performance degrades, the monitoring equipment issues an alarm signal and prompts maintenance personnel to carry out inspection and maintenance.

[0069] The working principle of the solar CPV / T heat pump energy storage integrated energy supply system provided by this utility model is as follows:

[0070] Upon receiving the start-up signal, the solar CPV / T heat pump energy storage integrated energy supply system first performs an initialization operation. The replenishment pump 7 starts working to ensure that the ethylene glycol circulation loop between the ethylene glycol circulation pump 6 and the CPV / T photovoltaic module 1 is full of ethylene glycol.

[0071] (1) Operation of CPV / T solar collector system

[0072] The CPV / T photovoltaic module 1 begins to receive sunlight and convert it into electrical and thermal energy. The electrical energy is converted into alternating current by the inverter 2, and then connected to the power grid via the grid connection box 3 or stored in the electrochemical energy storage device 4. Ethylene glycol, as a heat exchange medium, absorbs thermal energy in the CPV / T photovoltaic module 1 and is transported to the solar thermal heat exchanger 10 by the ethylene glycol circulation pump 6.

[0073] (2) Operation of the domestic hot water supply system

[0074] The domestic cold water pump 9 delivers cold water from the domestic water tank 8 to the solar thermal heat exchanger 10, where ethylene glycol releases heat energy to heat the domestic water. The heated domestic water then passes through the heat pump heat exchanger 11, where it is further heated by the heat pump power supply system if necessary, before flowing into the energy storage tank 12 for storage. When domestic hot water is needed, the domestic hot water pump 13 delivers hot water from the energy storage tank 12 to the user.

[0075] (3) The heat pump power supply system is working

[0076] The heat pump energy supply system switches between cooling and heating modes through the regulation of compressor 17 and four-way valve 18. In heating mode, the refrigerant such as Freon in the heat pump heat exchanger 11 absorbs heat from the domestic water, releases heat energy after compression by compressor 17, and heats the indoor air through indoor heat exchanger 19. The first throttling element 15 and the second throttling element 16 are used to regulate the flow and pressure of the refrigerant to ensure stable system operation.

[0077] (4) Operation of the user-side energy supply system

[0078] The indoor heat exchange circulation pump 20 transfers heat energy from the indoor heat exchanger 19 to the heat dissipation terminal 21, such as underfloor heating and fan coil units, providing users with a comfortable indoor environment. The electrochemical energy storage device 4 stores electrical energy during off-peak electricity hours or when the CPV / T photovoltaic module 1 generates excess power, for unforeseen needs. The hot water in the energy storage tank 12 provides domestic hot water when needed, ensuring users have access to it at any time. The solar thermal heat exchanger 10, heat pump heat exchanger 11, and energy storage tank 12 are all equipped with bypass pipes. If a component fails, the bypass pipes can be used to bypass the faulty component, ensuring the system continues to operate. The energy storage tank 12 is also equipped with an electric heater as an emergency backup heat source, ensuring users still have access to hot water under extreme weather conditions.

[0079] Using a solar CPVT heat pump energy storage integrated energy supply system as described in this embodiment, the start-up and shutdown of various heat exchangers, electronic expansion valves, solenoid valves, and pumps are controlled according to different solar radiation and seasonal energy supply demands to achieve stable system operation under different operating conditions. Specifically, based on different solar radiation and seasonal demands, there are 30 types of energy supply demands (as shown in Table 1). Based on this, the solar CPVT heat pump energy storage integrated energy supply system in this embodiment has 21 operating modes (such as...). Figures 2-22 (As shown).
