[0029] Example 1

[0030] Reference Figures 1-4 As an embodiment of the present invention, a central air conditioning waste heat recovery device is provided, comprising: an installation unit 100 and a waste heat recovery unit 200.

[0031] The two symmetrical clamping plates 101 in the mounting unit 100 can initially position the device on both sides of the central air conditioning cooling outdoor unit, thus initially fixing the device's position. The fixing component 102 located between the two clamping plates 101, although not detailed, can assist in adjusting the relative position of the two clamping plates 101 to a certain extent to adapt to the outdoor unit.

[0032] Within the waste heat recovery unit 200, a support frame 201, fixedly installed on one side of the installation unit 100, provides a foundation and support for the heat exchanger 202 and the hot water tank 203. The heat exchanger 202 is fixed inside the support frame 201, and its inlet and outlet are connected to the hot water tank 203 via water pipes 204. The function of the heat exchanger 202 is to realize the heat exchange between hot air and water, transferring the waste heat generated by the central air conditioning to the water in the tank. The hot water tank 203 is used to store the hot water after heat exchange for subsequent use.

[0033] The fabric duct 300 installed between the installation unit 100 and the waste heat recovery unit 200 is used to guide the hot air discharged from the central air conditioning to the waste heat recovery unit 200, so that the hot air can smoothly enter the heat exchanger 202 for heat exchange.

[0034] First, place the two clamping plates 101 of the installation unit 100 roughly on both sides of the central air conditioning unit's outdoor unit. Use the fixing component 102 to make simple position adjustments so that the clamping plates 101 are initially attached to the outdoor unit. Next, fix the support frame 201 of the waste heat recovery unit 200 to one side of the installation unit 100, so that the air outlet end of the fabric duct 300 is initially aligned with one end of the support frame 201. Then, bring the air inlet end of the fabric duct 300 close to the air outlet of the outdoor unit to complete the initial installation.

[0035] Workflow: When the central air conditioning unit is running, the outdoor unit discharges hot air, which enters the heat exchanger 202 inside the support frame 201 through the fabric duct 300. In the heat exchanger 202, the hot air exchanges heat with water, the water absorbs heat and its temperature rises, and the hot water flows through the water pipe 204 into the heat energy water tank 203 for storage, which can be used for hot water supply, etc.

[0036] It should be noted that a circulation pump is installed at the connection between the water tank and water pipe 204 to ensure normal water circulation.

[0037] Example 2

[0038] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, the fixing assembly 102 includes a fixing frame 102a symmetrically arranged between two clamping plates 101, and guide rods 102b slidingly passing through both ends of the fixing frame 102a. The guide rods 102b at both ends of the fixing frame 102a are staggered. The function of the guide rods 102b is to provide guidance for the movement of the fixing frame 102a, ensuring the stability and accuracy of the movement of the fixing frame 102a.

[0039] The fixing assembly 102 also includes two protruding plates 102c symmetrically fixed on the fixing frame 102a, a slide rod 102d fixedly connected between the two protruding plates 102c, two sliding plates 102e symmetrically slidably sleeved on the slide rod 102d, and a spring 102f sleeved on the slide rod 102d and connected at both ends to the two sliding plates 102e respectively. The function of the spring 102f is to provide elastic force. When the sliding plate 102e is pushed or pulled, the spring 102f will compress or extend accordingly, thereby driving the sliding plate 102e to slide on the slide rod 102d. One side of the sliding plate 102e is in contact with the end face of the fixing frame 102a and can move under the action of the spring 102f, thereby adjusting the distance between the two clamping plates 101.

[0040] The two clamping plates 101 are arranged parallel to each other and the anti-slip pads 103 on one side can increase the friction with the surface of the outdoor unit, prevent the device from sliding during use, and improve the stability of the installation.

[0041] Multiple scissor structures 104 are provided between the slide plate 102e and the clamping plate 101, including a first connecting rod 104b and a second connecting rod 104c rotatably connected by a pivot 104a. The ends of the first connecting rod 104b and the second connecting rod 104c of adjacent scissor structures 104 are hinged. The ends of the first connecting rod 104b and the second connecting rod 104c of the scissor structure 104 near the slide plate 102e are hinged to different slide plates 102e. The function of the scissor structure 104 is to convert the linear motion of the slide plate 102e into a change in the distance between the two clamping plates 101, facilitating the adjustment device to adapt to outdoor units of different sizes. The T-shaped sliders fixedly connected to the ends of the first connecting rod 104b and the second connecting rod 104c of the scissor structure 104 near the clamping plate 101 slide with the T-shaped grooves provided on the clamping plate 101, further ensuring the stability of the movement of the scissor structure 104.

[0042] The bracket 206, which is fixedly connected between the fixed frame 102a and the support frame 201, serves to support the support frame 201, ensuring that the support frame 201 is stably installed on one side of the mounting unit 100. The heat exchanger 202 adopts a serpentine structure and is equipped with heat-absorbing fins 205 arranged in a rectangular array. The serpentine structure and heat-absorbing fins 205 greatly increase the heat exchange area and improve the heat exchange efficiency, allowing hot air and water to exchange heat more fully.

[0043] The air outlet of the fabric duct 300 is sealed to one end of the support frame 201 to prevent hot air leakage. Several connecting rings 301 are provided on the side of the air inlet near the scissor structure 104, corresponding one-to-one with each rotating shaft 104a and fixedly connected. When the scissor structure 104 moves and causes the rotating shaft 104a to move, the air inlet of the fabric duct 300 can be folded or unfolded synchronously to ensure smooth adjustment of the air inlet channel and ensure that the device can work normally under different outdoor unit sizes.

[0044] First, based on the dimensions of the central air conditioning outdoor unit, manually push or pull the sliding plate 102e to compress or extend the spring 102f, causing the scissor structure 104 to unfold or retract. During this process, the T-shaped slider slides within the T-shaped groove, ensuring stable movement of the scissor structure 104, thereby precisely adjusting the distance between the two clamping plates 101, allowing the clamping plates 101 to tightly clamp the outdoor unit. The anti-slip pad 103 enhances the stability of the clamping. Then, the support frame 201 is firmly fixed to one side of the installation unit 100 using the bracket 206, ensuring a sealed connection between the air outlet end of the fabric duct 300 and one end of the support frame 201. Finally, the connecting ring 301 at the air inlet end of the fabric duct 300 is fixedly connected to the rotating shaft 104a of the scissor structure 104 one-to-one.

[0045] When the central air conditioning system is running, the hot air exhausted from the outdoor unit enters the heat exchanger 202 inside the support frame 201 through the fabric duct 300. In the heat exchanger 202, the serpentine structure and heat-absorbing fins 205 ensure full contact between the hot air and water, achieving efficient heat exchange. Heat is transferred from the hot air to the water inside the heat exchanger 202. The hot water after heat exchange flows through the water pipe 204 into the thermal energy water tank 203 for storage, and can be used for hot water supply, etc. When the size of the outdoor unit changes, the scissor mechanism 104 is adjusted, causing the air inlet end of the fabric duct 300 to fold or unfold with the rotating shaft 104a, ensuring smooth airflow and continued normal operation of the system.

[0046] The design of the fixed component 102 allows the device to better adapt to outdoor units of different sizes, resulting in more stable installation. The structural design of the heat exchanger 202 improves waste heat recovery efficiency, and the connection between the air inlet end of the fabric duct 300 and the rotating shaft 104a ensures smooth airflow under different operating conditions, enhancing the adaptability and practicality of the device, effectively improving energy utilization, and reducing energy waste and thermal pollution.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
