Description

Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to a combined air conditioning unit. Background Art

[0002] As modern building environmental control systems have increasingly higher requirements for air quality, modular air conditioning units have been widely used in commercial buildings and industrial facilities due to their modular design, high efficiency and energy saving, and multifunctional integration. In order to improve human comfort and health in air-conditioned environments, more and more modular air conditioning units are equipped with air purification devices, such as photocatalyst technology and negative ion generators.

[0003] In actual application, different air-conditioning projects require different sizes of combined air-conditioning unit boxes, and are affected by factors such as space layout, air duct design, maintenance and repair, so they need to be flexible to adapt to various installation conditions. Existing photocatalyst negative ion generators lack versatility and flexibility, so they are difficult to be directly applied to combined air-conditioning unit boxes of various sizes and structures. This results in the inability to easily integrate air purification functions into various types of combined air-conditioning units in air-conditioning projects with strong customization requirements and complex diversified scenarios, which increases design costs, installation difficulties, and the complexity of later maintenance.

[0004] In addition, in the field of air purification, negative ion generators, as a common purification method, have unique advantages. Negative ion generators can generate a large number of negative ions, which combine with pollutants in the air through electric charge, thereby settling or removing them. However, in actual applications, the purification effect of negative ion generators is often affected by many factors, such as the type and concentration of pollutants in the air and the humidity of the environment. Therefore, how to improve the purification effect of negative ion generators has become an urgent problem to be solved.

[0064] like Figure 1-Figure 11 As shown, some embodiments of the present application provide a combined air-conditioning unit.

[0065] See also Figure 1 , which is a schematic diagram of the internal structure of a combined air-conditioning unit.

[0066] The combined air conditioning unit comprises a housing 1 , a primary filter device 2 arranged in the housing 1 , a fan 3 , a heat exchanger 4 and an air purification device 5 .

[0067] The housing 1 has an air inlet and an air outlet; the indoor air can circulate between the combined air conditioning unit and the indoor space through the air inlet and the air outlet.

[0068] The primary filter device 2 is arranged in the housing 1 near the air inlet; the primary filter device 2 is used for preliminarily filtering the air entering the combined air conditioning unit.

[0069] The fan 3 is disposed in the housing 1 and is used to drive the air flow from the air inlet to the air outlet.

[0070] The fan 3 can be a centrifugal fan or a cross-flow fan according to factors such as specific air conditioning needs, noise control requirements and installation space conditions.

[0071] The heat exchanger 4 is arranged in the housing 1 and is located between the air inlet and the air outlet along the air flow direction.

[0072] The heat exchanger 4 is used for heat exchange to heat or cool the air.

[0073] The air purification device 5 is disposed in the housing 1 , and can be disposed on the air inlet side or the air outlet side of the heat exchanger 4 , or on the air inlet side or the air outlet side of the fan 3 .

[0074] See also Fig.11 , is a schematic structural diagram of the air purification device 5.

[0075] The air purification device 5 is composed of a plurality of purification modules 100 , so that the overall size of the air purification device 5 is adapted to the inner cavity size of the housing 1 .

[0076] Specifically, Figure 2-Figure 10 As shown, the purification module 100 includes a module frame 110, an ultraviolet light source assembly 140, a photocatalyst assembly 150 and a negative ion generator 160 which are sequentially arranged in the module frame 110 along the air flow direction.

[0077] The housing 1 of the combined air conditioning unit has a rectangular cross-section along a direction perpendicular to the air flow direction.

[0078] To adapt to the internal shape of the shell 1, the outer contour of the module frame 110 is also rectangular. Multiple purification modules 100 can be arranged and stacked in sequence, so that the overall size of the air purification device 5 is compatible with the inner cavity size of the shell 1, and can adapt to combined air-conditioning unit shells 1 of different specifications.

[0079] In the purification module 100 , the negative ion generator 160 is used to ionize the air to generate negative ions.

[0080] Medical research shows that negatively charged particles in the air increase the oxygen content in the blood, which is beneficial to the transportation, absorption and utilization of blood oxygen. It has the effects of promoting human metabolism, improving human immunity, enhancing human muscle strength, and regulating the balance of body functions.

[0081] Since dust and bacteria in the air are easily adsorbed by negative charges, in order to improve the efficiency of negative ion generation and enable more negative ions to be sent into the room through the air outlet, in some embodiments of the present application, a filter assembly 120, an electrostatic adsorption assembly 130, an ultraviolet light source assembly 140, and a photocatalyst assembly 150 are sequentially arranged on the air inlet side of the negative ion generator 160.

[0082] The filter assembly 120 can perform preliminary filtration on the air entering the purification module 100 and effectively intercept large dust particles and particulate matter in the air.

[0083] The electrostatic adsorption component 130 uses the electrostatic field to adsorb tiny particles in the air onto the electrode, further improving the dust removal effect. The combination of the filter and the electrostatic adsorption technology can significantly reduce the dust content in the air, providing a better working environment for the negative ion generator.

[0084] Furthermore, the ultraviolet light source assembly 140 is used to generate ultraviolet rays, which can activate the surface of the photocatalyst of the photocatalyst assembly 150 and can effectively reduce the bacteria content in the air.

[0085] Finally, the air passes through the negative ion generator 160, where the air is ionized to generate negative ions. Since the dust, impurities, and bacteria content in the air is very low at this time, the efficiency of generating negative ions in the air is improved.

[0086] In the above-mentioned combined air-conditioning unit, the air purification device 5 is composed of a plurality of purification modules 100, and adopts a modular design, which can adapt to the combined air-conditioning unit casings 1 of different specifications; at the same time, the air purification device 5 is combined with the filter assembly 120 and the electrostatic adsorption assembly 130 to significantly reduce the dust in the air, and then through the photocatalytic technology, it can effectively reduce the bacterial content in the air, provide a better working environment for the negative ion generator, further improve the negative ion generation efficiency, and improve the purification effect.
