Description

Technical Field

[0001] This application relates to the field of air source heat pump water heater technology, and in particular to a cold air recovery system for air source heat pump water heaters. Background Technology

[0002] Air source heat pump water heaters are energy-saving and environmentally friendly hot water supply devices that can replace boilers and are not limited by resources. They use green, pollution-free refrigerant to absorb heat from the air, and through the work of a compressor, produce domestic hot water at temperatures above 50 degrees Celsius, with an annual COP value exceeding 3.0. Air source heat pump water heaters are suitable for indoor swimming pools, hotels, villas, hair salons, bathhouses, factories, schools, farms, and other places requiring centralized hot water heating. Air source heat pump water heaters can also be used for cooling during the heating process, and can also be installed in places that require cooling capacity but whose requirements are not high.

[0003] When an air source heat pump water heater is in use, it recovers the cooled air. When the cooled air recovery device is in use, if the temperature of the cooled air after heat dissipation is higher than the ambient temperature, the cooled air cannot be used. If the temperature of the cooled air after heat dissipation is lower than the ambient temperature, the cooled air can be recovered and reused. However, ordinary cooled air recovery devices cannot easily change the transmission path of the cooled air according to the temperature. Therefore, we propose a cooled air recovery system for air source heat pump water heaters. Utility Model Content

[0004] This application provides a cold air recovery system for air source heat pump water heaters to solve the problems mentioned above.

[0005] This application provides a cold air recovery system for an air source heat pump water heater, comprising:

[0006] The system includes a cold air source mechanism and an air source heat pump water heater unit, wherein multiple air source heat pump water heater units are provided and are arranged opposite to the cold air source mechanism.

[0007] The recycling shell has a recycling fan fixedly connected to the middle of its right end. The outlet of the recycling fan is connected to a recycling pipe. An inner pipe is movably and sealed inside the recycling pipe. A ventilation hose is fixedly connected to the outer side of the right end of the inner pipe in a ring array. A connecting frame is fixedly connected to the upper and lower sides of the right end of the recycling pipe. An electric telescopic rod is fixedly connected to the middle of the right end of the connecting frame. The left end of the transmission rod of the electric telescopic rod is fixedly connected to the middle of the right end of the inner pipe.

[0008] The lower end of the recycling tube has multiple connecting holes at equal intervals, and each connecting hole has a connecting tube fixedly installed at its lower end. The lower end of the inner tube has multiple switch holes at equal intervals. The inner wall of the recycling tube is fixedly connected to the front and rear sides of the right side. The front and rear sides of the right end of the connecting rod are fixedly connected to a connecting ring by a fixing rod. The front and rear sides of the right end of the connecting ring are fixedly connected to multiple plug-in sealing rods at equal intervals.

[0009] Preferably, the plurality of plug-in sealing rods and the plurality of ventilation hoses are arranged opposite each other on the left and right sides of the opening on the right end face of the inner tube, and the plug-in sealing rods are plugged into the opening on the right end face of the inner tube to seal the air inlet of the ventilation hoses.

[0010] Preferably, the inner tube has a rectangular opening at the connecting rod, and the front and rear ends of the connecting rod pass through the rectangular opening and are fixedly connected to the inner wall of the recovery tube.

[0011] Preferably, a first temperature sensor is fixedly connected to the outside of the recycling shell, and a second temperature sensor is fixedly connected to the inside of the recycling shell.

[0012] Preferably, the first temperature sensor, the second temperature sensor, and the electric telescopic rod are all connected to the controller mechanism via transmission wires.

[0013] Preferably, the front end of the recovery shell is open, and the recovery shell is located on the rear side of each air source heat pump water heater unit.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] The structure provided in this application embodiment has a first temperature sensor and a second temperature sensor that detect the air temperature outside the recovery housing and the temperature inside the recovery housing, respectively. If the external temperature is greater than the internal air temperature, the electric telescopic rod drives the inner tube to move backward, so that the connection hole and the switch hole do not coincide, and the connection hole is blocked, so that the ventilation hose connects to the inner cavity of the inner tube, thereby transmitting cold air to the set position through the ventilation hose, and using the cold air to cool the external equipment again, and then recovering and using the cold air again.

[0016] Conversely, if the external temperature is lower than the internal air temperature, the electric telescopic rod drives the inner tube to move forward, causing the connection hole and the switch hole to coincide, and the plug-in sealing rod is plugged into the air inlet of the ventilation hose to seal the ventilation hose. This allows the hot air to be transferred to the outside through the connection pipe, preventing the hot air from affecting the heat dissipation of the air source heat pump water heater unit.

[0026] like Figures 1-3 As shown in the figure, this application provides a cold air recovery system for an air source heat pump water heater, comprising:

[0027] The system includes a cold air source mechanism 1 and an air source heat pump water heater unit 2, wherein multiple air source heat pump water heater units 2 are provided and are arranged opposite to the cold air source mechanism 1.

[0028] The recycling housing 4 has a recycling fan 5 fixedly connected to the middle of its right end. The outlet of the recycling fan 5 is connected to a recycling pipe 6. An inner pipe 8 is movably and sealed inside the recycling pipe 6. A ventilation hose 10 is fixedly connected to the outer side of the right end of the inner pipe 8 in a ring array. A connecting frame 9 is fixedly connected to the upper and lower sides of the right end of the recycling pipe 6. An electric telescopic rod 11 is fixedly connected to the middle of the right end of the connecting frame 9. The electric telescopic rod 11 adopts an existing telescopic rod on the market and is existing technology. The left end of the transmission rod of the electric telescopic rod 11 is fixedly connected to the middle of the right end of the inner pipe 8.

[0029] The lower end of the recycling tube 6 has multiple connecting holes 12 at equal intervals, and each connecting hole 12 is fixedly provided with a connecting tube 7. The lower end of the inner tube 8 has multiple switch holes 13 at equal intervals. The front and rear sides of the right side of the inner wall of the recycling tube 6 are fixedly connected to a connecting rod 17. The front and rear sides of the right end of the connecting rod 17 are fixedly connected to a connecting ring 19 by a fixing rod 18. The front and rear sides of the right end of the connecting ring 19 are fixedly connected to multiple plug-in sealing rods 3 at equal intervals.

[0030] like Figure 2 and Figure 3 As shown, multiple plug-in sealing rods 3 and multiple ventilation hoses 10 are arranged opposite each other on the left and right sides of the opening on the right end face of the inner tube 8, and the plug-in sealing rods 3 are plugged into the opening on the right end face of the inner tube 8 to seal the air inlet of the ventilation hoses 10.

[0031] Specifically, the air outlet of the ventilation hose 10 can be installed at the equipment that needs heat dissipation to provide heat dissipation for the external equipment.

[0032] like Figure 3 As shown, the inner tube 8 has a rectangular opening 16 at the connecting rod 17, and the front and rear ends of the connecting rod 17 pass through the rectangular opening 16 and are fixedly connected to the inner wall of the recovery tube 6.

[0033] Specifically: Rectangular opening 16 is the path of displacement of connecting rod 17 when it moves left and right in inner tube 8.

[0034] like Figure 1 and Figure 2 As shown, a first temperature sensor 14 is fixedly connected to the outside of the recycling shell 4, and a second temperature sensor 15 is fixedly connected to the inside of the recycling shell 4.

[0035] The first temperature sensor 14, the second temperature sensor 15, and the electric telescopic rod 11 are all connected to the controller mechanism via transmission wires.

[0036] Specifically: the first temperature sensor 14, the second temperature sensor 15 and the electric telescopic rod 11 all use existing equipment on the market and are all existing technologies. The first temperature sensor 14 and the second temperature sensor 15 respectively detect the air temperature outside and inside the recovery housing 4.

[0037] like Figure 1 As shown, the front end of the recovery housing 4 is open, and the recovery housing 4 is located on the rear side of each air source heat pump water heater unit 2.

[0038] Specifically: the recovery housing 4 can collect the air after it has been cooled, and when the temperature of the cooled air is lower than the external temperature, it can be recycled and reused.

[0039] Principle: Both the cold air source mechanism 1 and the air source heat pump water heater unit 2 are existing equipment on the market and are existing technologies, so they will not be described in detail here;

[0040] The cold air source mechanism 1 blows out cold air to dissipate heat from the air source heat pump water heater unit 2. The dissipated air enters the interior of the recovery shell 4, and the recovery fan 5 is started to draw out the dissipated air from the interior of the recovery shell 4.

[0041] Furthermore, the first temperature sensor 14 and the second temperature sensor 15 respectively detect the air temperature outside the recovery housing 4 and the temperature inside the recovery housing 4. If the external temperature is greater than the internal air temperature, the electric telescopic rod 11 drives the inner tube 8 to move backward, so that the connection hole 12 and the switch hole 13 do not coincide, and the connection hole 12 is blocked, so that the ventilation hose 10 connects to the inner cavity of the inner tube 8, thereby transmitting cold air to the set position through the ventilation hose 10, using the cold air to cool the external equipment again, and then recycling the cold air again.

[0042] Conversely, if the external temperature is lower than the internal air temperature, the electric telescopic rod 11 drives the inner tube 8 to move forward, so that the connecting hole 12 and the switch hole 13 coincide, and the plug-in sealing rod 3 is plugged into the air inlet of the ventilation hose 10 to seal the ventilation hose 10, thereby transmitting hot air to the outside through the connecting pipe 7, and preventing the hot air from affecting the heat dissipation of the air source heat pump water heater unit 2.

[0043] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
