Description

A smart control and energy-saving device for HVAC central air conditioning Technical Field

[0001] This utility model relates to the field of air conditioning energy-saving devices, and in particular to an intelligent control energy-saving device for HVAC central air conditioning. Background Technology

[0002] Central air conditioning (HVAC) is a centralized air conditioning system used in large buildings or building complexes. It is designed to provide a comfortable temperature and humidity environment indoors and to achieve air circulation and purification. Intelligent control energy-saving devices are equipment that use advanced technologies and algorithms to intelligently manage and control the central air conditioning system in order to achieve energy-saving operation.

[0003] Most existing intelligent control energy-saving devices are directly installed on the outside of air conditioning equipment. Due to the large amount of dust in the external environment, it may gradually accumulate on the ventilation openings and heat dissipation channels of the device, hindering air circulation and further aggravating heat dissipation difficulties. At the same time, dust may also enter the inside of the device, covering the surface of electronic components, affecting their heat dissipation effect, and may also cause sensor misjudgment or reduced accuracy, thereby affecting the normal operation and energy-saving effect of the air conditioning system.

[0004] Therefore, since most of the existing devices are directly installed on the outside of the air conditioning equipment, and there is a lot of dust in the external environment, which may accumulate on the vents and heat dissipation channels, exacerbating the heat dissipation difficulties and affecting the normal operation of the internal components of the device, an intelligent control and energy-saving device for HVAC central air conditioning can be designed, with a dustproof structure added to the outside of the device to maintain the normal operation of the device. Summary of the Invention

[0005] To overcome the problem that most existing devices are directly installed on the outside of air conditioning equipment, which may accumulate dust in the external environment, exacerbating heat dissipation difficulties and affecting the normal operation of internal components.

[0006] The technical solution of this utility model is as follows: an intelligent control and energy-saving device for HVAC central air conditioning, including a housing; an air inlet pipe for introducing airflow is fixedly connected to one side of the housing, and an air outlet pipe for discharging heat is fixedly connected to the side of the housing away from the air inlet pipe. A fan is fixedly connected to the inner side of the air inlet pipe. The air inlet pipe and the air outlet pipe are arranged in the same manner. A first threaded groove is opened on the outer wall of the end of the air inlet pipe away from the housing. A connecting ring is sleeved on the outer side of the end of the air inlet pipe away from the housing. A second threaded groove is opened on the inner wall of the connecting ring. A dustproof plate is fixedly connected to one side of the connecting ring. The connecting ring is threadedly connected to the air inlet pipe through the second threaded groove along the first threaded groove. Dustproof pads are fixedly connected to each corner of the outer side of the housing.

[0007] Furthermore, a cover plate is provided on the top of the housing, and multiple sets of plug-in posts are fixedly connected around the lower edge of the cover plate.

[0008] Furthermore, a plug-in hole is provided at the upper edge of the housing corresponding to the plug-in post, and the plug-in post is positioned and engaged with the housing through the plug-in hole.

[0009] Furthermore, a temperature sensor is provided on one side of the housing, penetrating deep into the housing, and a mounting plate is fixed to the side of the housing away from the temperature sensor.

[0010] Furthermore, three sets of placement grooves are horizontally spaced at the bottom of the inner side of the housing, and the sensor body, controller body and inverter body are arranged horizontally in sequence on the inner side of the housing. Two sets of limiting plates are arranged vertically above the sensor body, controller body and inverter body.

[0011] Furthermore, each end of the limiting plate is fixed with a fixing stud that passes through the housing, and a fixing nut is fitted on the outside of the fixing stud.

[0012] Furthermore, a telescopic valve is provided at the connection between the air inlet pipe and the housing, and an electromagnetic control valve is installed on the outside of the telescopic valve. The electromagnetic control valve is electrically connected to the temperature sensor.

[0013] The beneficial effects of this utility model are as follows: The dustproof plate fitted on the outside of one end of the air inlet pipe adopts a specially designed filter structure. Based on the principle of filtration and interception, it can efficiently intercept dust in the incoming airflow. At the same time, the dustproof pad installed on the outside of the housing, with its good elasticity and sealing performance, tightly fits the gaps in the housing, effectively preventing dust from entering the housing through the gaps. Through these dual dustproof measures, the accumulation of dust on electronic components can be significantly reduced, maintaining the cleanliness of the surface of electronic components. This not only reduces the risk of faults such as short circuits and poor contact caused by dust accumulation, but also ensures that the accuracy of the sensor is not affected by dust, enabling it to continuously and accurately sense various operating parameters and provide reliable data support for intelligent control energy-saving devices. In addition, reducing dust accumulation can also reduce the mechanical resistance during equipment operation, maintain the stable and efficient operation of the air conditioning system, and effectively improve the overall performance of the air conditioning system. In summary, this heat dissipation and dustproof structure can significantly extend the cleaning and maintenance cycle of the equipment, reduce maintenance costs, and significantly improve the operational stability and reliability of the equipment.

Multiple sets of plug-in posts 102 are fixedly connected around the lower edge of the cover plate 101. The plug-in posts 102 can position and connect the cover plate 101 to the housing 1.

[0023] Please refer to Figure 2. In this embodiment, a plug hole 103 is provided at the upper edge of the housing 1 corresponding to the plug post 102. The plug post 102 is positioned and engaged with the housing 1 through the plug hole 103. When the cover plate 101 is lifted, the plug post 102 is positioned and engaged with the housing 1 through the plug hole 103.

[0024] Please refer to Figure 2. In this embodiment, a temperature sensor 105 is provided on one side of the housing 1, extending through the housing 1 and into its interior. A mounting plate 106 is fixed to the side of the housing 1 away from the temperature sensor 105. The mounting plate 106 is fixed to the outside of the air conditioning equipment for use.

[0025] Please refer to Figures 2-3. In this embodiment, three sets of placement grooves 107 are horizontally spaced at the bottom of the inner side of the housing 1.

Next, lift the dustproof plate 205, allowing the connecting ring 204 to be threaded into the air inlet pipe 2 through the second thread groove 206 along the first thread groove 203. Finally, fix the mounting plate 106 to the outside of the air conditioning unit. It is then ready for use. Through the cooperation of the sensor body 108, controller body 109, and inverter body 110, it can monitor the air... The system operates to achieve energy-saving control.
