Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, specifically a low-temperature air conditioning unit with heat recovery function. Background Technology

[0002] An air conditioning unit is an integrated device that can regulate air temperature, humidity, cleanliness, and airflow speed. It uses refrigerant circulation to achieve cooling or heating through core components such as compressors, condensers, and evaporators. With the help of fans, it circulates air. Some units also have air filtration functions to remove dust and other impurities. Air conditioning units are widely used in shopping malls, office buildings, factories, and other places to create a comfortable and healthy indoor environment for people and meet the diverse air conditions required in different scenarios.

[0003] In low-temperature environments, traditional air conditioning units suffer from significant energy waste and defrosting problems during operation, making it difficult to meet the current demands for high efficiency, energy saving, and stable operation. On the one hand, the evaporator of the air conditioning unit is prone to frosting under low-temperature conditions. Conventional electric heating defrosting or shutdown defrosting methods not only consume a lot of electricity but also cause drastic fluctuations in indoor temperature, affecting environmental comfort and equipment operational stability. On the other hand, a large amount of waste heat generated during air conditioning operation is usually directly discharged to the outside without being effectively recovered and utilized, resulting in a huge waste of energy.

[0015] This utility model provides a low-temperature air conditioning unit with heat recovery function. It has the following beneficial effects:

[0016] (1) When the air conditioning unit is started, the hot air generated by the air conditioning unit will be discharged through the exhaust hole of the air outlet shell. When the air conditioning unit needs to be defrosted, the hot air can be recovered.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1

[0028] A preferred embodiment of the low-temperature air conditioning unit with heat recovery function provided by this utility model is, for example... Figure 1-4 As shown: A low-temperature air conditioning unit with heat recovery function includes an air conditioning unit body 1, a ventilation pipe 2 connected to one side of the air conditioning unit body 1, a control component 3 on the front of the air conditioning unit body 1, and a connecting component 4 on one side of the control component 3.

[0029] The control component 3 includes an air outlet shell 311, which is fixedly connected to the front of the air conditioning unit body 1. The front of the air conditioning unit body 1 is provided with an air outlet and an air inlet. The air outlet shell 311 is adapted to the air conditioning unit body 1. An exhaust hole is provided on one side of the air outlet shell 311, and a connecting pipe 312 is provided on the other side of the air outlet shell 311. The connecting pipe 312 is connected to the air outlet shell 311.

[0030] The connecting component 4 includes a connecting shell 412, which is fixedly connected to the front of the air conditioning unit body 1 and is adapted to the air conditioning unit body 1. A sliding hole is provided on the upper surface of the connecting shell 412, and a slide rail 413 is provided at the bottom of the connecting shell 412, which is fixedly connected to the bottom of the connecting shell 412. The control component 3 also includes a pad 317, which is fixedly connected to the upper surface of the air outlet shell 311. A limit groove is provided on the upper surface of the pad 317. A rotating hole is provided on the upper surface of the connecting pipe 312, and a fixing plate 313 is provided on the inner wall of the connecting pipe 312. The fixing plate 313 is fixedly connected to the inner wall of the connecting pipe 312, and a rotating plate 314 is provided on the inner wall of the fixing plate 313. The rotating plate 314 is connected to the inner wall of the connecting pipe 312 via an axis. The bearing is rotatably connected to the inner wall of the fixed plate 313. A connecting rod 315 is provided on the inner wall of the rotating hole. The connecting rod 315 is fixedly connected to the upper surface of the rotating plate 314. The connecting rod 315 is rotatably connected to the inner wall of the rotating hole. A rotating rod 316 is provided on the upper surface of the connecting rod 315. The rotating rod 316 is fixedly connected to the upper surface of the connecting rod 315. The rotating rod 316 is slidably connected to the inner wall of the limiting groove. A connecting groove is opened on the upper surface of the rotating rod 316. A fixing block 318 is provided on the upper surface of the air outlet shell 311. The fixing block 318 is fixedly connected to the upper surface of the air outlet shell 311. A rotating rod 319 is provided on one side of the fixing block 318. The rotating rod 319 is rotatably connected to the fixing block 318 through a bearing seat. The rotating rod 319 is slidably connected to the inner wall of the connecting groove.

[0031] Furthermore, in this embodiment, when the air conditioning unit 1 is started and running, the hot air generated by it will be discharged to the outside through the exhaust hole of the air outlet shell 311. When it is necessary to defrost the air conditioning unit 1 and recover this hot air, the following steps can be taken: First, rotate the rotating rod 2 319 so that it rotates around the fixed block 318. As the rotating rod 2 319 rotates, it will gradually move away from the state of blocking the rotating rod 1 316. At this time, the rotating rod 1 316 is in a movable state, and the operator can rotate the rotating rod 1 316 to make it move. The inner wall of the limiting groove rotates. Since the pad 317 is connected to the rotating rod 316, the rotation of the rotating rod 316 will drive the pad 317 to move, which in turn will cause the pad 317 to drive the connecting rod 315 to rotate on the inner wall of the rotating hole. The rotation of the connecting rod 315 will drive the rotating plate 314 to rotate until the rotating plate 314 completely blocks the exhaust hole. At this time, the hot air cannot be discharged through the exhaust hole and instead flows into the inner wall of the connecting pipe 312. Then the hot air will enter the air conditioning unit body 1 through the connecting component 4 to assist defrosting, thereby realizing the recycling of hot air.

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of the low-temperature air conditioning unit with heat recovery function provided by this utility model is as follows: Figure 1-4 As shown: The connecting component 4 also includes a second connecting pipe 411, which is connected to the first connecting pipe 312. A baffle 414 is provided on the inner wall of the slide rail 413, and the baffle 414 is slidably connected to the inner wall of the slide rail 413. The baffle 414 is slidably connected to the inner wall of the first sliding hole. A second sliding hole and a vent hole are respectively opened on one side of the baffle 414. A support plate 415 is provided on the upper surface of the connecting shell 412, and the support plate 415 is fixedly connected to one side of the baffle 414. A sliding groove is opened on the upper surface of the support plate 415, and a sliding rod 416 is provided on the inner wall of the sliding groove. The sliding rod 416 is slidably connected to the inner wall of the sliding groove and to the second sliding hole. A handle 417 is provided on the upper surface of the sliding rod 416, and the handle 417 is fixedly connected to the upper surface of the sliding rod 416.

[0034] Furthermore, in this embodiment, when hot air needs to enter the air conditioning unit body 1 for recycling, the air intake can be controlled by operating the baffle 414: pull the baffle 414 upwards so that it moves synchronously upwards along the slide rail 413 and the inner wall of the sliding hole one. As the baffle 414 slides, its air leakage hole is precisely aligned with the air intake hole of the air conditioning unit body 1. At this time, the air intake channel is opened, and the connecting shell 412 is connected to the air conditioning unit body 1. Hot air flows into the connecting pipe two 411 through the connecting pipe one 312, and then smoothly enters the air conditioning unit body 1 through the connecting shell 412. After the air intake channel is opened, push the handle 417 to drive the sliding rod 416 to slide along the sliding groove and the inner wall of the sliding hole two. When the sliding rod 416 slides to the upper surface of the air conditioning unit body 1, it precisely fixes the baffle 414, thereby achieving precise control of the air intake volume, ensuring that the hot air is stably delivered along the predetermined path, and meeting the defrosting and energy recovery requirements of the air conditioning unit.

[0035] During operation, when the air conditioning unit 1 is started, the hot air it generates is discharged outward through the exhaust port of the air outlet shell 311. When defrosting the air conditioning unit 1 and recycling this hot air is required, the following steps can be taken: First, rotate the rotating rod 319 so that it rotates around the fixed block 318. As the rotating rod 319 rotates, it gradually disengages from the state of blocking the rotating rod 316. At this time, the rotating rod 316 is in a movable state, and the operator can rotate the rotating rod 316 so that it rotates on the inner wall of the limiting groove. Since the pad 317 is connected to the rotating rod 316, the rotation of the rotating rod 316 will drive the pad 317 to move, which in turn will drive the connecting rod 315 to rotate on the inner wall of the rotating hole. The rotation of the connecting rod 315 will then drive the rotating plate 314 to rotate until the rotating plate 314 completely blocks the exhaust port. At this time, the hot air cannot be discharged through the exhaust hole and instead flows into the inner wall of the connecting pipe 312. Then, the air intake can be controlled by operating the baffle 414: pull the baffle 414 upward so that it moves upward synchronously along the slide rail 413 and the inner wall of the sliding hole 1. As the baffle 414 slides, the air leakage hole on it is precisely aligned with the air intake hole of the air conditioning unit body 1. At this time, the air intake channel is opened, and the connecting shell 412 is connected to the air conditioning unit body 1. The hot air flows into the connecting pipe 411 through the connecting pipe 312 and then smoothly enters the air conditioning unit body 1 through the connecting shell 412. After the air intake channel is opened, push the handle 417 to drive the sliding rod 416 to slide in the sliding groove and the inner wall of the sliding hole 2. When the sliding rod 416 slides to the upper surface of the air conditioning unit body 1, it just fixes the baffle 414 firmly, thereby achieving precise control of the air intake volume and ensuring that the hot air is stably delivered along the predetermined path to meet the defrosting and energy recovery requirements of the air conditioning unit.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
