The use of the above device is not convenient for improving the heating efficiency of the water storage tank, which leads to low heat exchange efficiency of the device. For this reason, we propose a dual-source heat pump heat exchanger with heat energy recovery function. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The dual-source heat pump heat exchanger with heat recovery function uses the device body and PV / T panel assembly in combination, so that the PV / T panel assembly absorbs the heat generated by solar energy and serves as the source side of the water source heat pump. When the heat pump is running, it can absorb the heat generated by the PV / T panel assembly to cool the PV / T panel assembly while heating the water storage tank, thereby improving the operating energy efficiency of the heat pump and the power generation efficiency of the PV / T assembly.

[0014] 2.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4A dual-source heat pump heat exchanger with heat energy recovery function includes a device body 1, a PV / T panel assembly 2 is arranged on the top of the device body 1, a mounting groove 3 is opened on the front of the device body 1, a fan 4 is installed on the inner wall of the device body 1, a first dustproof net 5 is installed on the inner wall of the mounting groove 3, a rectangular groove 6 is opened on the side of the device body 1, and a second dustproof net 7 is installed on the inner wall of the rectangular groove 6, a hot water storage tank 8 is installed on the inner wall of the device body 1, a connecting pipe 9 is installed on the side of the hot water storage tank 8, a circulating pump 10 is installed on the other side of the connecting pipe 9, a water inlet pipe 11 is installed on the other side of the circulating pump 10, and a sewage pipe 12 is installed on the other side of the connecting pipe 9. Since the PV / T panel assembly 2 is installed on the top of the device body 1, the PV / T panel assembly 2 can generate electricity by sunlight, and then when the PV / T panel assembly 2 is in use, the PV / T assembly absorbs the heat generated by solar energy as the source side of the water source heat pump. When the heat pump is running, it can absorb PV / T while heating the hot water storage tank 8. The heat generated by the components is used to cool the PV / T component panels, thereby improving the energy efficiency of the heat pump. At the same time, the installed fan 4 allows the heat pump's air source mode to operate at the same time when solar energy is insufficient. When there is no heat from the solar energy at all, it can automatically switch to the air source mode to ensure that the solar energy is fully utilized while ensuring the stable operation of the system and the continuous supply of hot water. The installed first dustproof net 5 and second dustproof net 7 can isolate the dust outside the device, thereby preventing dust from entering the inside of the device.

[0022] A heat exchange channel 14 is installed at the bottom of the PV / T panel assembly 2 to facilitate the organic combination of the solar photovoltaic assembly and the solar heat collection channel, and the heat exchange channel 14 is a serpentine channel design. Due to the shape of the heat exchange channel 14, it is not easy to leak and has a long service life. Since the PV / T panel assembly 2 is a photovoltaic and thermal integrated panel, it can generate electricity and heat, greatly improving the utilization rate of solar energy. At the same time, the PV / T panel assembly 2 has an annual power generation efficiency that is about 10% higher than that of ordinary photovoltaic panels, and the heat pump has an operating efficiency that is about 30% to 70% higher than that of ordinary air source heat pumps.

[0023] The bottom of the PV / T panel assembly 2 is installed with an insulation backboard 13, and the insulation backboard 13 fits the bottom of the PV / T panel assembly 2. Since the insulation backboard 13 is adhered to the bottom of the PV / T panel assembly 2, the device is both fit-fitting and beautiful.

[0024] The outer walls of the water inlet pipe 11 and the sewage pipe 12 both pass through the side of the device body 1, and control valves are installed on the outer walls of the water inlet pipe 11 and the sewage pipe 12. The control valves are installed on the outer walls of the water inlet pipe 11 and the sewage pipe 12 so that the control valves can control the entry and discharge of water, thereby facilitating the use of the device.

[0025] The first dustproof net 5 and the second dustproof net 7 are detachable structures, and the first dustproof net 5 and the second dustproof net 7 are installed on the inner walls of the mounting groove 3 and the rectangular groove 6 by elastic buckles. Since the first dustproof net 5 and the second dustproof net 7 are detachable, it is convenient to clean the dust attached to the surface of the first dustproof net 5 and the second dustproof net 7.

[0026] The device body 1 is controlled by an intelligent management platform. A dual-source heat pump is arranged inside the device body 1, and the dual-source heat pump is controlled by a heat station system. The heat station system is a composite system of a PV / T-coupled dual-source heat pump. Since the heat station system is a composite system of a PV / T-coupled dual-source heat pump, the system heats the hot water storage tank 8 through a dual-source (water source and air source) heat pump.

[0027] Working principle: during operation, when the PV / T panel assembly 2 is used, the PV / T panel assembly 2 absorbs the heat generated by the solar energy and serves as the source side of the water source heat pump. When the heat pump is running, it can absorb the heat generated by the PV / T panel assembly 2 to cool the PV / T panel assembly 2 while heating the hot water storage tank 8, thereby improving the operating energy efficiency of the heat pump and the power generation efficiency of the PV / T panel assembly 2. When the fan 4 is used, when the solar energy is insufficient, the air source mode of the heat pump will intervene at the same time. When there is no heat available from the solar energy, it can automatically switch to the air source mode to ensure that the solar energy is fully utilized while ensuring the stable operation of the system and the continuous supply of hot water. The installation of the dustproof net 5 and the second dustproof net 7 makes the first dustproof net 5 and the second dustproof net 7 fixedly connected to the inner walls of the installation groove 3 and the rectangular groove 6 by elastic buckles. At the same time, the elastic buckles make it convenient to disassemble the first dustproof net 5 and the second dustproof net 7, so as to clean the dust attached to the surface of the first dustproof net 5 and the second dustproof net 7. Since the PV / T panel assembly 2 adds the innovative technology of the heat exchange flow channel 14 on the basis of the PV / S photovoltaic assembly, the solar photovoltaic assembly and the solar energy collection flow channel are organically combined together, the heat exchange area is large, the heat exchange is fast and uniform, and the heat on the photovoltaic panel is taken away by the circulation of the flow channel working medium, the remaining heat can be effectively used to produce domestic hot water and heating, and the power generation efficiency is improved by lowering the temperature of the photovoltaic assembly.
