Description

Technical Field

[0001] This utility model applies to the field of air conditioning equipment technology and provides a constant temperature, constant humidity and high cleanliness air conditioning unit. Background Technology

[0002] Due to the limitations of their working principle, common industrial air conditioning units must be placed outdoors for heat exchange. However, in northern or desert regions, extreme weather events such as sandstorms are frequent. If industrial air conditioning units are used in these areas and are directly exposed to the outdoor environment, a large amount of sand and dust will enter the air conditioning unit with the air, greatly reducing the service life and performance of the unit. Therefore, air conditioning units used in these areas must be equipped with filtration devices at the air inlet to filter sand and dust from the air before it enters the air conditioning unit. However, traditional filter screens are easily clogged by sand and dust, which affects the air intake of the air conditioning unit. This means that the filter screen replacement and cleaning cycle is too frequent, making it inconvenient to use and costly. Utility Model Content

[0003] Therefore, this utility model provides a constant temperature and humidity high cleanliness air conditioning unit. The air conditioning unit is placed in the hollow cavity of a sealed outdoor cabinet. The air entering the outdoor cabinet is first desanded by a sand remover before entering the hollow cavity for use by the air conditioning unit. The sand and dust filter unit of the sand remover can not only quickly separate the sand and dust, but also quickly discharge the sand and dust using a sand and dust exhaust fan, so as not to cause the sand and dust filter unit to become clogged.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature and humidity high-cleanliness air conditioning unit, including an outdoor cabinet, a hollow cavity being provided inside the outdoor cabinet, a main air intake duct being provided at the front end of the outdoor cabinet, the main air intake duct being connected to the hollow cavity, and the following components being arranged sequentially from front to back inside the hollow cavity:

[0005] A sand removal machine includes a sand and dust separation chamber that runs through the front and rear. The front port of the sand and dust separation chamber is sealed and connected to the main air inlet duct. Several sand and dust filter units are arranged sequentially inside the sand and dust separation chamber. Each sand and dust filter unit includes two sand and dust separation plates arranged in a V-shape. A V-shaped air duct that is wider at the front and narrower at the rear is formed between the two sand and dust separation plates. The wide port at the front end of the V-shaped air duct is the mixing air inlet end, and the narrow port at the rear end of the V-shaped air duct is the sand and dust outlet end. The sand and dust outlet end is connected to a sand and dust collection duct. Several ventilation holes and several sand-blocking fins are provided on the sand and dust separation plates. The sand-blocking fins are located on the inner side of the filter plate facing the V-shaped air duct and are inclined towards the sand and dust outlet end. The several ventilation holes and several sand-blocking fins are adapted to each other.

[0006] An air conditioning intake filter, including at least one intake filter screen;

[0007] An air conditioning unit, which is equipped with an air conditioning intake fan and an air conditioning outlet duct.

[0008] Furthermore, it also includes an air conditioning return air duct, which is connected to the hollow cavity, and the connection point between the air conditioning return air duct and the hollow cavity is located between the sand remover and the air conditioning inlet filter.

[0009] Furthermore, the air conditioning return air duct is connected to the main air intake duct via an auxiliary air intake duct. An auxiliary air intake valve is installed on the auxiliary air intake duct, and a main air intake valve is installed on the main air intake duct. The connection point between the auxiliary air intake duct and the main air intake duct is located on the side of the main air intake valve away from the hollow cavity.

[0010] Furthermore, the dust filtration unit also includes a filter guide plate disposed between the two dust separation plates.

[0011] Furthermore, a dust collection chamber is provided below the dust separation chamber, the lower end of the dust collection pipe is connected to the dust collection chamber, the dust collection chamber is connected to a dust discharge pipe, and a dust exhaust fan is provided between the dust discharge pipe and the dust collection chamber.

[0012] Furthermore, the number of air intake filters is preferably two, including a primary coarse screen air intake filter and a secondary fine screen air intake filter arranged sequentially from the sand remover to the air conditioning unit. The outer walls of the primary coarse screen air intake filter and the secondary fine screen air intake filter are sealed and fitted to the inner wall of the hollow cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In the solution of this utility model, a clean and stable air intake is provided for the air conditioning unit working outdoors through a dual filtration method of sand removal machine and air intake filter. The sand removal machine, through the sand separation plate set in a V shape and the sand exhaust fan, can efficiently separate and discharge most of the sand in the air while maintaining a large air volume ventilation performance.

[0015] 2. By connecting the main air intake duct and the air conditioning return air duct through the auxiliary air intake duct, outdoor air can be directly introduced into the hollow cavity through the air conditioning return air duct when there is no sandstorm and the air quality is good. This air intake route can turn off the sand remover to achieve direct air intake, which reduces the energy consumption of the sand remover and increases the air intake volume.

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] Example, see attached document Figure 1 ~Appendix Figure 2 The present invention provides a constant temperature and humidity high cleanliness air conditioning unit 700, including an outdoor cabinet 100, a hollow cavity 110 inside the outdoor cabinet 100, a main air inlet duct 200 at the front end of the outdoor cabinet 100, the main air inlet duct 200 being connected to the hollow cavity 110, and a sand remover 500, an air conditioning air inlet filter 600, and an air conditioning unit 700 being arranged sequentially from front to back inside the hollow cavity 110.

[0034] The 500 sand remover is used to separate solid particles such as sand and dust from the air. Figure 3 ~Appendix Figure 5 As shown, it includes a sand and dust separation chamber 510 that runs through the front and back. The front port of the sand and dust separation chamber 510 is sealed and connected to the main air inlet duct 200. Several sand and dust filter units 520 are arranged sequentially inside the sand and dust separation chamber 510, as shown in the attached figure. Figure 6 ~Appendix Figure 8 As shown, the dust filtration unit 520 includes two V-shaped dust separation plates 521. A V-shaped air duct 522, wider at the front and narrower at the back, is formed between the two dust separation plates 521. The wide end of the V-shaped air duct 522 is the mixing air inlet, and the narrow end is the dust outlet. The dust outlet is connected to a dust collection pipe 524. A dust collection chamber 530 is located below the dust separation chamber 510. The lower end of the dust collection pipe 524 is connected to the dust collection chamber 530, and the dust collection chamber 530 is connected to a dust emission point. A dust extraction fan 540 is installed between the dust emission pipe 550 and the dust collection chamber 530. A filter guide plate 523 is also installed between the two dust separation plates 521. The filter guide plate 523 is generally located in the middle of the two dust separation plates 521. When outside air enters the V-shaped air duct 522, the dust separation plates 521 can evenly distribute the airflow on both sides and guide the movement direction of dust particles, thereby increasing the air circulation speed. The dust separation plates 521 are provided with several ventilation holes and several sand-blocking fins, as shown in the attached figure. Figure 8As shown, the sand-blocking fins are located on the inner side of the filter plate facing the V-shaped air duct 522 and are inclined towards the sand and dust outlet end. Several ventilation holes are matched with several sand-blocking fins. In this structure, the sand-blocking fins will cover the ventilation holes. When the air mixed with sand and dust enters the V-shaped air duct 522, due to the blocking of the sand-blocking fins, sand and dust particles will hit the sand-blocking fins and the filter guide plate 523 and pass through the gradually narrowing V-shaped air duct 522. Finally, they will enter the sand and dust collection pipe 524 from the sand and dust outlet end and be finally extracted from the sand and dust collection chamber 530 to the outside by the sand and dust exhaust fan 540. The relatively clean air will be discharged from the ventilation holes into the hollow cavity 110 for use by the air conditioning unit 700.

[0035] The air conditioning intake filter 600 can further filter the air after dust removal. In this embodiment, the air conditioning intake filter 600 includes two intake filters, including a primary coarse screen intake filter 610 and a secondary fine screen intake filter 620 arranged sequentially from the sand remover 500 to the air conditioning unit 700. The outer walls of the primary coarse screen intake filter 610 and the secondary fine screen intake filter 620 are sealed and fitted to the inner wall of the hollow chamber 110 to ensure the filtration effect. The two-stage filter improves the filtration effect.

[0036] The air conditioning unit 700 is equipped with an air conditioning intake fan and an air conditioning outlet duct 710. It is also equipped with an air conditioning return air duct 300. The air conditioning return air duct 300 is used to circulate indoor air into the hollow cavity 110. The air conditioning return air duct 300 is connected to the hollow cavity 110. The connection between the air conditioning return air duct 300 and the hollow cavity 110 is located between the sand remover 500 and the air conditioning intake air filter 600. This is because the air conditioning return air is already sand-removed and relatively clean, so it does not need to be sand-removed again by the sand remover 500.

[0037] In one embodiment, the air conditioning return air duct 300 and the main air intake duct 200 are also connected by an auxiliary air intake duct 400. An auxiliary air intake valve 410 is installed on the auxiliary air intake duct 400, and a main air intake valve 210 is installed on the main air intake duct 200. The connection point between the auxiliary air intake duct 400 and the main air intake duct 200 is located on the side of the main air intake valve 210 away from the hollow cavity 110. The auxiliary air intake duct 400 is mainly used to provide an air intake channel that bypasses the sand remover 500. It is used in conjunction with the sand remover 500. In weather conditions such as sandstorms, when the amount of sand and dust in the air is large, the sand remover 500 and the main air intake are turned on. Valve 210 is closed, and the auxiliary air intake valve 410 is closed. At this time, the outdoor air needs to be desanded by the sand remover 500 before entering the hollow chamber 110. However, in climates where the air quality meets the standards, the amount of sand and dust in the air is very small. At this time, the sand remover 500 and the main air intake valve 210 are closed, and the auxiliary air intake valve 410 is opened. At this time, the outdoor air does not need to pass through the sand remover 500, but enters the hollow chamber 110 directly through the air conditioning return air duct 300. In this case, the air intake volume is larger, and the sand remover 500 is closed, reducing the energy consumption of the entire equipment. This structure can improve the economic efficiency of the air conditioning unit 700.
