Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an energy-saving clean air conditioning unit. Background Technology

[0002] An air handling unit, also known as an air handling unit, is a centralized air handling system assembled from various air handling functional sections. It typically includes components such as a fan, heater, cooler, and filter. Through processes such as filtration, dehumidification, cooling, and heating, it processes the air to meet the requirements of constant temperature, constant humidity, and dust-free environments in special places such as laboratories and factory workshops.

[0003] In traditional air handling units, outdoor fresh air is often directly introduced for cooling, heating, humidification, or dehumidification during the fresh air processing, without effectively utilizing the significant energy contained in the exhaust air. This means that the cooling energy carried by the low-temperature air exhausted indoors in summer is wasted; and the heat in the exhaust air in winter is not recovered, causing the air conditioning unit to consume a large amount of extra energy to process fresh air, resulting in a huge waste of energy. In terms of air cleanliness, traditional air conditioning units mostly rely on simple pre-filters for air purification, which are relatively simple and inefficient, making it difficult to cope with increasingly complex air pollutants. For places with extremely high air quality requirements, the purification capacity of traditional air conditioning units is far from sufficient. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an energy-saving cleanroom air conditioning unit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An energy-saving clean air conditioning unit includes a unit casing, and a fresh air duct, an exhaust air duct and a supply air duct are respectively provided on the outside of the unit casing. The ends of the fresh air duct, the exhaust air duct and the supply air duct are all connected to the inside of the unit casing.

[0007] The unit casing has two fixed partitions inside, which sequentially divide the interior of the unit casing into a primary heat recovery chamber, a secondary heat recovery chamber, and a clean chamber. The inner wall of the primary heat recovery chamber is equipped with a drive motor, the output end of which is connected to a connecting shaft. The end of the connecting shaft is fixedly connected to a rotating blade, and the outer surface of the rotating blade is provided with a moisture-absorbing and heat-conducting layer.

[0008] Preferably, the inner walls of the secondary heat recovery chamber are respectively provided with an evaporation section and a condensation section, and a heat pipe bundle is fixedly connected between the evaporation section and the condensation section.

[0009] Preferably, a primary filtration layer is provided on one side of the inner wall of the cleanroom, a secondary filtration layer is fixedly connected to one side of the primary filtration layer, a higher filtration layer is fixedly connected to one side of the secondary filtration layer, an activated carbon adsorption layer is fixedly connected to one side of the higher filtration layer, a plasma purification layer is fixedly connected to one side of the activated carbon adsorption layer, and an ultraviolet sterilization layer is fixedly connected to one side of the plasma purification layer.

[0010] Preferably, a plurality of ultraviolet irradiation lamps are fixedly connected inside the ultraviolet sterilization layer.

[0011] Preferably, the primary filter layer is made of metal mesh material, the intermediate filter layer is made of glass fiber and polyester fiber material, and the advanced filter layer is made of ultrafine glass fiber filter paper material.

[0012] The beneficial effects of this utility model are:

[0013] This air conditioning unit combines a primary heat recovery chamber and a secondary heat recovery chamber. Outdoor fresh air enters the pre-cooling zone of the primary heat recovery chamber through a fresh air duct, while exhaust air mixes with the fresh air before entering this zone. A drive motor rotates the connecting shaft and impeller blades, allowing the moisture-absorbing and heat-conducting layer of the impeller blades to exchange heat and moisture between the exhaust and fresh air. In summer, the moisture-absorbing and heat-conducting layer of the impeller blades absorbs heat and moisture from the exhaust air and releases it to the fresh air on the fresh air side, achieving pre-cooling and dehumidification of the fresh air. In winter, it transfers the heat and moisture stored in the exhaust air to the fresh air, achieving preheating and humidification. Through heat conduction of the working fluid inside the heat pipe bundle in the secondary heat recovery chamber between the evaporation and condensation sections, efficient recovery of exhaust heat is achieved, significantly improving the energy efficiency of the air conditioning unit and achieving high energy savings.

[0014] This composite air purification module, consisting of a primary filtration layer, a secondary filtration layer, a high-level filtration layer, an activated carbon adsorption layer, a plasma purification layer, and an ultraviolet sterilization layer, effectively intercepts and captures particulate matter in the air. The activated carbon adsorption layer allows harmful gas molecules to adhere to the pore surface of the activated carbon for chemical adsorption. The plasma purification layer uses active particles in the plasma generated by high-voltage discharge to collide and chemically react with pollutants in the air, thereby purifying the air. The ultraviolet sterilization layer emits ultraviolet light that irradiates microorganisms in the air, killing them. Through the synergistic effect of multiple purification methods, it can comprehensively and efficiently remove various pollutants from the air, providing high-quality purified air for air conditioning units.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0023] Example:

[0024] Reference Figure 1-3 An energy-saving clean air conditioning unit includes a unit housing 1. A fresh air duct 2, an exhaust air duct 3, and an air supply duct 4 are respectively provided on the outside of the unit housing 1. The ends of the fresh air duct 2, the exhaust air duct 3, and the air supply duct 4 are all connected to the inside of the unit housing 1.

[0025] The unit casing 1 is internally fixedly connected to two partition plates 5, which sequentially divide the interior of the unit casing 1 into a primary heat recovery chamber 6, a secondary heat recovery chamber 7, and a clean room 8. The inner wall of the primary heat recovery chamber 6 is equipped with a drive motor 9, the output end of the drive motor 9 is connected to a connecting shaft 10, and the end of the connecting shaft 10 is fixedly connected to a rotating blade 11. The outer surface of the rotating blade 11 is provided with a moisture-absorbing and heat-conducting layer 12.

[0026] An evaporation section 13 and a condensation section 14 are respectively provided on both sides of the inner wall of the secondary heat recovery chamber 7, and a heat pipe bundle 15 is fixedly connected between the evaporation section 13 and the condensation section 14.

[0027] In this implementation scheme, when the air conditioning unit is running, outdoor fresh air first enters the primary heat recovery chamber 6 of the unit casing 1 through the fresh air duct 2 and indoor exhaust air enters through the exhaust air duct 3. Then, the drive motor 9 is started, and the drive motor 9 drives the connecting shaft 10 to rotate. When the connecting shaft 10 rotates, it drives the rotor blades 11 to rotate. Thus, the rotor blades 11 rotate slowly under the drive of the connecting shaft 10. At this time, the fresh air and exhaust air in the primary heat recovery chamber 6 pass through different parts of the rotor blades 11. In summer, when the exhaust air passes through the rotor blades 11, the moisture-absorbing and heat-conducting layer 12 on the rotor blades 11 absorbs the heat and moisture in the exhaust air. When the rotor blades 11 rotate to the fresh air side, the rotor blades 11 release the absorbed heat and moisture to the fresh air, so that the fresh air is pre-cooled and dehumidified before entering the subsequent processing stage. In winter, the heat and moisture in the exhaust air are transferred to the fresh air, realizing preheating and humidification.

[0028] Furthermore, when the fresh air and exhaust air processed by the primary heat recovery chamber 6 enter the secondary heat recovery chamber 7, since the heat pipe bundle 15 is a closed metal tube filled with working fluid, when the fresh air and exhaust air pass through the evaporation section 13 and condensation section 14 of the heat pipe bundle 15 respectively, the working fluid inside the heat pipe bundle 15 absorbs the heat of the exhaust air in the evaporation section 13 and releases the heat to the fresh air in the condensation section 14, thereby realizing heat transfer, maximizing the recovery and utilization of energy in the exhaust air, reducing the energy consumption of the air conditioning unit, and achieving the goal of energy saving.

[0029] Example 2:

[0030] Reference Figure 3Based on Embodiment 1, a technical solution is provided, including a primary filter layer 16 disposed on one side of the inner wall of the clean room 8, a secondary filter layer 17 fixedly connected to one side of the primary filter layer 16, a high-grade filter layer 18 fixedly connected to one side of the secondary filter layer 17, an activated carbon adsorption layer 19 fixedly connected to one side of the high-grade filter layer 18, a plasma purification layer 20 fixedly connected to one side of the activated carbon adsorption layer 19, and an ultraviolet sterilization layer 21 fixedly connected to one side of the plasma purification layer 20.

[0031] Several ultraviolet lamps 22 are fixedly connected inside the ultraviolet sterilization layer 21.

[0032] The primary filter layer 16 is made of metal mesh material, the intermediate filter layer 17 is made of glass fiber and polyester fiber material, and the advanced filter layer 18 is made of ultra-fine glass fiber filter paper material.

[0033] In this implementation scheme, when the treated fresh air and exhaust air enter the cleanroom 8, the air first passes through the primary filter layer 16, where large particles of dust and impurities are intercepted on the surface of the primary filter layer 16. The air then enters the intermediate filter layer 17, where smaller particulate pollutants are further intercepted. Next, the air passes through the advanced filter layer 18, thus intercepting almost all tiny particles, significantly improving air cleanliness. After physical filtration, the air then passes through the activated carbon adsorption layer 19, where harmful gas molecules in the air are adsorbed onto the active sites on the surface of the activated carbon in the adsorption layer 19. This causes the harmful gas molecules to adhere to the pore surface of the activated carbon, thus absorbing the pollutants. When the air filtered by the carbon adsorption layer 19 passes through the plasma purification layer 20, the active particles in the plasma generated by the high-voltage discharge collide and chemically react with the pollutants in the air, further enhancing the purification effect. Then, when the air purified by the plasma purification layer 20 passes through the ultraviolet sterilization layer 21, the ultraviolet irradiation lamp 22 emitted by the ultraviolet sterilization layer 21 irradiates the microorganisms in the air. The energy of the ultraviolet rays is absorbed by the DNA and RNA of the microorganisms, causing changes in their molecular structure, thereby destroying the genetic information and metabolic functions of the microorganisms, making them unable to reproduce and survive normally. This provides high-quality purified air for the air conditioning unit, meeting the strict air quality requirements of different places.
