[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] Existing air conditioning units lack cold energy recovery functionality. This lack of function leads to numerous drawbacks. In terms of energy utilization, the low-temperature cooling generated during the refrigeration process is directly released to the outside, resulting in significant energy waste, increased unit energy consumption, and a substantial rise in operating costs. Regarding environmental control, the inability to utilize recovered cold energy to assist defrosting or pre-cool fresh air causes large fluctuations in indoor temperature and humidity during defrosting, affecting environmental stability and reducing comfort and compatibility with production processes. From an equipment performance perspective, the lack of cold energy recovery forces the unit to operate at high loads for extended periods, accelerating equipment aging, shortening its lifespan, and reducing equipment reliability through frequent start-ups and shutdowns, while increasing maintenance frequency and repair costs.

[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 defrosting energy-saving low-temperature constant temperature and humidity air conditioning unit provided by this utility model is, for example... Figure 1-4 As shown: A defrosting energy-saving low temperature and humidity air conditioning unit includes an air conditioning unit body 1, wherein there are two air conditioning unit bodies 1. A temperature and humidity detector 2 is fixedly installed on the front of the air conditioning unit body 1. A cold energy recovery component 3 is provided on the upper surface of the air conditioning unit body 1. Control components 4 are provided on both sides of the air conditioning unit body 1.

[0029] The cold energy recovery component 3 includes a connecting pipe 311. A connecting hole is provided on one side of the connecting pipe 311, and a sliding hole is provided on the other side of the connecting pipe 311. The connecting pipe 311 is connected to the upper surface of the air conditioning unit body 1 and is used to connect two air conditioning unit bodies 1. A blower 312 is provided on one side of the connecting pipe 311. The blower 312 is fixedly installed on the upper surface of the air conditioning unit body 1 and is connected to the connecting pipe 311. A baffle 314 is provided on the inner wall of the sliding hole.

[0030] Control component 4 includes a ventilation pipe 411, which is connected to one side of the air conditioning unit body 1. A sliding hole 2 is provided on the outer wall of the ventilation pipe 411, and a baffle 2 414 is provided on the inner wall of the sliding hole 2.

[0031] The cold energy recovery component 3 also includes a slide rail 313, which is fixedly connected to the other side of the connecting pipe 311. A heat exhaust hole is provided on the upper surface of the air conditioning unit body 1, and a vent hole is provided on one side of the air conditioning unit body 1. A baffle 314 is provided on the inner wall of the sliding hole, and the baffle 314 is slidably connected to the inner wall of the sliding hole, blocking the connecting pipe 311 and controlling its ventilation. The baffle 314 is slidably connected to the inner wall of the slide rail 313 to prevent it from tilting. A fixing plate 315 is provided on the upper surface of the baffle 314; the fixing plate 315 is fixedly connected to the upper surface of the baffle 314 to fix it. A second connection hole is provided on the upper surface of plate 315. A connecting plate 316 is provided on the upper surface of the air conditioning unit body 1. The connecting plate 316 is fixedly connected to the upper surface of the air conditioning unit body 1. A fixing block 317 is provided on one side of the connecting plate 316. The fixing block 317 is fixedly connected to one side of the connecting plate 316. A rotating plate 318 is provided on one side of the fixing block 317. The rotating plate 318 is rotatably connected to the fixing block 317 through a bearing seat. A first connecting block 319 is provided at the bottom of the rotating plate 318. The first connecting block 319 is fixedly connected to the bottom of the rotating plate 318. The first connecting block 319 is slidably connected to the inner wall of the second connection hole to limit the position of the fixing plate 315.

[0032] Furthermore, in this embodiment, while one air conditioning unit 1 is operating normally, the other is in standby mode. When frost forms inside the operating air conditioning unit 1, the temperature and humidity detector 2 detects the internal condition of the air conditioning unit 1. When defrosting is required, the control system of the air conditioning unit 1 automatically switches. At this time, the standby air conditioning unit 1 quickly starts cooling, while the frosted air conditioning unit 1 enters the defrosting process. When heat transfer and defrosting between the air conditioning units 1 need to be coordinated, this can be achieved through the following operation: The rotating plate 318 is manipulated to rotate around the fixed block 317. The connecting block 319 rotates synchronously, causing it to disengage from the inner wall of the connecting hole 2 of the fixing plate 315. At this time, the fixing plate 315 can be slidably operated. The fixing plate 315 will drive the baffle 314 to slide synchronously along the slide rail 313 and the sliding hole 1 of the connecting pipe 311, thereby opening the channel of the connecting pipe 311. Then, the blower 312 is started, which delivers the air in the defrosting air conditioning unit body 1 to the air conditioning unit body 1 that needs to be cooled. This process can not only speed up the speed at which the cooling unit reaches the working temperature, but also ensure that the air conditioning unit body 1 that needs to be defrosted can defrost normally without interference, realizing the coordinated operation of defrosting and cooling.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of the defrosting energy-saving low-temperature constant temperature and humidity air conditioning unit provided by this utility model is as follows: Figure 1-4As shown: Control component 4 also includes a second slide rail 412, which is fixedly connected to the outer wall of the ventilation duct 411. A second baffle 414 is slidably connected to the inner wall of the second slide rail 412. A fixing rod 413 is provided at the other end of the second slide rail 412, and the fixing rod 413 is fixedly connected to the other end of the second slide rail 412. A sliding hole 3 is opened on one side of the fixing rod 413, and the second baffle 414 is slidably connected to the inner wall of the sliding hole 2. The sliding baffle 414 can block the ventilation duct 411 to cut off the connection with the air conditioning unit body 1. A connecting block 415 is provided on one side, which is fixedly connected to one side of the baffle 414. The connecting block 415 is slidably connected to the inner wall of the sliding hole 3, and a connecting groove is provided on one side of the connecting block 415. A fixing frame 416 is provided on one side of the fixing rod 413, which is fixedly connected to one side of the fixing rod 413. A sliding block 417 is provided on the inner wall of the fixing frame 416, which is slidably connected to the inner wall of the fixing frame 416. The fixing frame 416 is slidably connected to the inner wall of the connecting groove for fixing the connecting block 415.

[0035] Furthermore, in this embodiment, when a certain air conditioning unit body 1 needs to defrost, the following procedure can be followed: slide the corresponding sliding block 417 upwards, so that it moves on the inner wall of the fixed frame 416 and simultaneously disengages from the connecting groove of the connecting block 2 415. At this time, push the baffle 2 414, and the baffle 2 414 slides along the inner wall of the slide rail 2 412 and the sliding hole 3, finally blocking the ventilation pipe 411 and preventing the air inside the defrosting unit from continuing to circulate; while for the air conditioning unit body 1 that needs to cool, the opposite operation is adopted, that is, the baffle 2 414 is released from blocking the ventilation pipe 411 through similar steps, so that the ventilation pipe 411 is unobstructed and the unit can ventilate and cool normally, thereby realizing independent control of the two units in different operating states.

[0036] During operation, while one air conditioning unit 1 is running normally, the other is in standby mode. When frost forms inside the operating air conditioning unit 1, the temperature and humidity detector 2 detects the internal condition and determines that defrosting is required. The control system of the air conditioning unit 1 automatically switches, and the standby unit 1 quickly begins cooling, while the frosted unit 1 enters the defrosting process. Simultaneously, the rotating plate 318 can be rotated, causing the connecting block 319 to rotate. The connecting block 319 slides out from the inner wall of the connecting hole 2 on the fixed plate 315. This allows the fixed plate 315 to slide, causing the baffle 314 to slide along the inner wall of the slide rail 313. Simultaneously, the baffle 314 slides along the inner wall of the sliding hole 1 on the other side of the connecting pipe 311, allowing the air conditioning unit 1 to cool. Air can be supplied through connecting pipe 311, and then blower 312 can be started to send the air inside the air conditioning unit body 1 that needs defrosting into the air conditioning unit body 1 that needs cooling. This allows the air conditioning unit body 1 that needs cooling to reach the working temperature as soon as possible without delaying the defrosting process. When defrosting an air conditioning unit body 1, the corresponding sliding block 417 can be slid upward. The sliding block 417 slides on the inner wall of the fixed frame 416, and at the same time, the sliding block 417 will slide out from the inner wall of the connecting groove of connecting block two 415. At this time, baffle two 414 can be pushed. Baffle two 414 slides on the inner wall of sliding rail two 412 and sliding hole three. At this time, baffle two 414 will block the ventilation pipe 411, preventing the air inside the air conditioning unit body 1 that needs defrosting from continuing to circulate. Similarly, the ventilation pipe 411 on the side of the air conditioning unit body 1 that needs cooling can be opened to allow the air conditioning unit body 1 that needs cooling to ventilate.

[0037] 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.
