Description

Technical Field

[0001] This application relates to the field of indoor air conditioning technology, and more specifically, to a jet-flow air supply air conditioning unit. Background Technology

[0002] In specialized indoor spaces such as industrial workshops, computer rooms, and enclosed office workstations, the hot air generated by cooling equipment cannot be exhausted outdoors due to building layout, pipeline laying limitations, and actual usage needs. In such scenarios, integrated indoor cooling equipment is typically used for localized cooling. While this type of equipment can reduce the temperature in areas where people are active to some extent, the problem of inconvenient condensate treatment is particularly prominent.

[0003] The condensate of existing indoor integrated cooling equipment is generated in the evaporator on the cold air side. Due to the limitations of equipment installation location and spatial layout, the traditional method of condensate drainage through external drain pipes is difficult to achieve. Some equipment is equipped with a water collection box for collecting condensate, which requires frequent manual cleaning. This not only increases the workload and maintenance cost, but the water collection box is also prone to water accumulation, overflow, and leakage, which can easily damage surrounding equipment and the ground.

[0004] Existing integrated indoor cooling equipment, when applied to indoor spaces with special structures, struggles to balance localized cooling effects with the convenience and safety of condensate treatment, failing to meet the long-term stable usage requirements of such special indoor spaces. The existing technology still has significant shortcomings and room for improvement. Summary of the Invention

The cooling air outlet area, located between the indoor unit and the outdoor unit of the air conditioning unit, has a cold air outlet for discharging the cold air blown in by the indoor unit's outlet into the room; wherein... The indoor unit of the air conditioning unit has a condensate tray, and the outdoor unit of the air conditioning unit is equipped with a condenser. The condensate tray and the condenser are connected by a first pipe. A pump body is installed on the first pipe. The pump body pumps the condensate in the condensate tray into the space above the condenser. The water drips onto the condenser through the first pipe.

[0008] In one possible implementation, the fan is a centrifugal fan.

[0009] In one possible implementation, the indoor unit air inlet is provided with an indoor unit filter screen, and the indoor unit filter screen is arranged at an angle.

[0010] In one possible implementation, the outdoor unit of the air conditioning unit includes: The outdoor unit's air inlet is located on the back panel of the top side of the main body of the air conditioning unit; A cooling fan is installed on top of the outdoor unit of the air conditioning unit; wherein, The cooling fan draws indoor air into the outdoor unit of the air conditioning unit through the outdoor unit's air inlet, and after passing through the condenser, exchanges heat with the condenser to remove the heat from the condenser. It also discharges water from the drain pan into the indoor ceiling through the outdoor unit's air outlet.

[0011] In one feasible embodiment, the outdoor unit air inlet is provided with an outdoor unit filter screen, which is arranged vertically.

[0012] In one possible implementation, the top of the condenser is open; the first pipe, located inside the outdoor unit of the air conditioning unit, is suspended above the condenser and has multiple through holes at its bottom; the bottom of the condenser is connected to the drip tray via a second pipe; wherein, The pump body pumps water into the first pipe above the condenser through the first pipe, and the water drips onto the condenser through the through hole at the bottom. If the water is not completely discharged, the remaining water is discharged into the water receiving tray through the second pipe.

[0013] In one possible implementation, the cooling air outlet area is composed of the top plate of the indoor unit of the air conditioning unit, the bottom plate of the outdoor unit of the air conditioning unit, the back plate and the front plate of the main body of the air conditioning unit, and at least one cold air outlet is provided on the front plate.

[0014] In one possible implementation, the cold air outlet is an angle-adjustable air outlet.

This eliminates the need for frequent manual cleaning of the water collection box, significantly reducing maintenance workload and costs. It completely avoids the hidden dangers of water overflow and leakage from traditional water collection boxes, protecting surrounding equipment and the ground from damage. At the same time, the condensate in the condenser is discharged from the outdoor unit's air outlet using the unit's own cooling fan, eliminating the need for a dedicated drainage pipe. This is suitable for use in indoor spaces with special structures where it is difficult to easily connect an external drainage pipe, effectively solving the problem of condensate treatment being limited by spatial layout.

[0024] like Figures 1 to 5 As shown, this application provides a jet-flow air supply air conditioning unit, including the air conditioning unit body, the air conditioning unit indoor unit 1, the air conditioning unit outdoor unit 2, and the cooling air outlet area 3.

[0025] The air conditioning unit includes an indoor unit 1 and an outdoor unit 2. The indoor unit 1 has an indoor air outlet 16 on its top. The outdoor unit 2 is located on top of the indoor unit 1 and is arranged vertically at intervals from the indoor unit 1. The outdoor unit 2 has an outdoor air outlet 28 on its top. The cooling air outlet area 3 is located between the indoor unit 1 and the outdoor unit 2 and has a cold air outlet 31 for discharging the cold air blown in by the indoor unit air outlet 16 into the room.

[0026] Specifically, the condensation area of ​​the indoor unit 1 of the air conditioning unit has a water collection tray 15, and the outdoor unit 2 of the air conditioning unit is equipped with a condenser 25. The water collection tray 15 and the condenser 25 are connected through a first pipe 26. A pump body 27 is installed on the first pipe 26. The pump body 27 is used to pump the condensate in the water collection tray 15 into the condenser 25, and then the cooling fan 24 of the outdoor unit 2 of the air conditioning unit discharges the water that has entered the condenser 25 through the air outlet 28 of the outdoor unit.

[0027] By stacking the outdoor unit 2 of the air conditioning unit on top of the indoor unit to form spaced cooling air outlet areas 3, cold air is precisely delivered to the indoor activity area through the dedicated cold air outlet 31, achieving targeted air supply and cooling for specific work areas. The cold air delivery is more concentrated, and the local cooling effect is better. At the same time, a water collection tray 15 is set in the condensate area of ​​the indoor unit, and a condenser 25 is installed in the outdoor unit. The condensate is automatically transported through the first pipeline 26 and the pump body 27, replacing the traditional manual cleaning of the water collection box. This completely eliminates the tedious operation of frequent manual maintenance, greatly reduces maintenance costs, and also avoids water overflow from the water collection box. The problem of water leakage damaging surrounding equipment and the ground is addressed by utilizing the outdoor unit's own cooling fan 24 to discharge condensate from the condenser 25 through the outdoor unit's air outlet 28, eliminating the need for an additional external drainage pipe 26. This perfectly adapts to the layout limitations of special indoor spaces where external drainage is not possible. Furthermore, the efficient discharge of condensate is achieved through the exhaust of the air conditioning unit's outdoor unit 2, combining condensate treatment with the equipment's exhaust function. The structure is more compact and easier to use, effectively balancing the localized cooling effect with the convenience and safety of condensate treatment, making it suitable for the use needs of special indoor spaces such as industrial workshops and computer rooms. In one embodiment, the indoor unit 1 of the air conditioning unit includes an indoor unit air inlet 11 and a fan.

[0028] The indoor unit air inlet 11 is located on the back panel of the bottom side of the air conditioning unit body, for indoor air to enter the indoor unit 1 of the air conditioning unit; the indoor unit air inlet 11 is provided with an indoor unit filter screen 12, which is arranged at an angle.

[0029] Specifically, the indoor unit air inlet 11 is located on the back panel of the bottom side of the air conditioning unit. It has a grille-type through-hole structure with the ventilation grilles arranged in a matrix. While ensuring an effective air intake area, it blocks large particles and lint from entering the indoor unit, preventing internal components from being contaminated or stuck. The indoor unit filter 12 is detachably installed on the inner side of the indoor unit air inlet 11. The filter is arranged at a 30°-60° angle along the back panel. This inclined design increases the contact area between the indoor air and the filter, improving the filtration effect of dust and impurities. It also allows the dust trapped by the filter to slide off naturally under gravity, reducing the probability of dust accumulation and clogging of the filter. The detachable structure facilitates later cleaning and replacement. The opening direction of the indoor unit air inlet 11 is adapted to the preset airflow direction inside the indoor unit. After entering through the air inlet, the indoor air can flow smoothly to the centrifugal fan 13 along a straight airflow path, minimizing air intake resistance and reducing air volume loss.

[0030] A fan is installed inside the indoor unit 1 of the air conditioning unit, and the air outlet of the fan is located at the top of the indoor unit 1, forming the indoor unit air outlet 16. Further, the fan is a centrifugal fan 13.

[0031] Centrifugal fan 13 is fixedly installed inside the indoor unit 1 of the air conditioning unit. Its installation position is above the indoor unit's air inlet 11 and on the side of the evaporator 14's air outlet. Its overall installation height matches the indoor unit's air outlet 16 at the top of the indoor unit 1, ensuring seamless connection between the centrifugal fan 13's air outlet and the indoor unit's air outlet 16. The centrifugal fan 13 consists of a volute, a centrifugal impeller, and a drive motor. The drive motor is coaxially connected to the centrifugal impeller, providing power for the centrifugal fan 13's operation. Its operation is based on the principle of centrifugal pressure boosting: the drive motor drives the centrifugal impeller to rotate at high speed inside the volute. The blades generate centrifugal force on the air entering the fan, causing the air to be accelerated and pressurized within the volute. Compared to conventional axial fans, centrifugal fans 13 have higher air pressure, which can effectively overcome the resistance of the evaporator 14 and air path inside the indoor unit, ensuring stable air intake efficiency and cold air delivery power. The air outlet of centrifugal fans 13 is set vertically upward and connected to the indoor unit air outlet 16 at the top of the indoor unit 1 of the air conditioning unit. The cold air pressurized by the fan can be directly blown into the cooling air outlet area 3 from the indoor unit air outlet 16, avoiding leakage or turbulence of cold air during the delivery process and ensuring the effectiveness of cold air delivery.

[0032] The fan draws indoor air into the indoor unit 1 of the air conditioning unit through the indoor unit air inlet 11, and after passing through the evaporator 14, forms cold air, which is then blown into the cooling air outlet area 3 through the indoor unit air outlet 16.

[0033] It should be noted that the evaporator 14 is fixedly installed in the condensation area of ​​the indoor unit 1 of the air conditioning unit, and is located in the air path between the indoor unit air inlet 11 and the air inlet of the centrifugal fan 13. It is a finned tube evaporator 14, which improves the heat exchange efficiency. A water receiving tray 15 is provided directly below the evaporator 14 to receive the condensate produced by the evaporator 14.

[0034] In this embodiment, the overall airflow process of the indoor unit 1 of the air conditioning unit is as follows: After the centrifugal fan 13 starts, it forms a negative pressure to draw indoor air through the indoor unit air inlet 11. The indoor air enters the indoor unit after being filtered through the indoor unit air inlet 11. It first flows through the evaporator 14. The indoor hot air exchanges heat fully with the low-temperature heat exchange copper tubes and heat dissipation fins of the evaporator 14. The heat of the hot air is absorbed by the refrigerant in the heat exchange copper tubes, and the air temperature drops rapidly to form cold air. At the same time, the water vapor in the air condenses into condensate on the surface of the evaporator 14 when it encounters the cold air. It drips naturally along the fins and copper tubes of the evaporator 14 into the water collection tray 15 below. The cold air that has completed the heat exchange is continuously pressurized and transported by the centrifugal fan 13. It is blown vertically upward into the cooling air outlet area 3 between the indoor unit 1 and the outdoor unit through the fan outlet and indoor unit air outlet 16 of the air conditioning unit indoor unit 1. Finally, it is directionally discharged into the room through the cold air outlet 31 of the cooling air outlet area 3 to achieve cooling of the indoor work area.

[0035] In one embodiment, the outdoor unit 2 of the air conditioning unit includes an outdoor unit air inlet 21 and a cooling fan 24.

[0036] The outdoor unit air inlet 21 is located on the back panel of the top side of the main body of the air conditioning unit; the outdoor unit air inlet 21 is equipped with an outdoor unit filter screen 22, which is arranged vertically.

[0037] Specifically, the outdoor unit air inlet 21 is located on the back panel of the top side of the air conditioning unit body and is connected to the internal cavity of the outdoor unit 2. It has a grille-type through-hole structure. The ventilation grille can be made of metal in one piece and arranged in a matrix. While ensuring the effective air intake area, it can directly block large particles and lint in the indoor air from entering the interior of the outdoor unit 2, avoiding contamination and blockage of internal components such as the condenser and cooling fan 24, which would affect heat exchange and ventilation efficiency. The location of the outdoor unit air inlet 21 corresponds to the air inlet end of the condenser inside the outdoor unit 2.

[0038] Furthermore, the outdoor unit filter 22 is a detachable structure, fixedly mounted on the inner side of the outdoor unit air inlet 21, and arranged vertically along the back panel of the air conditioning unit body, fitting snugly against the grille structure of the outdoor unit air inlet 21, thereby achieving secondary filtration of the air entering the air conditioning unit outdoor unit 2; the filter is made of polyester fiber material, which can effectively trap dust, fine particles and other impurities in the air, preventing impurities from adhering to the condenser fin surface and affecting heat exchange efficiency; the detachable structure facilitates later cleaning and replacement operations, and the vertical installation form does not require additional support structure, adapting to the compact internal layout of the air conditioning unit outdoor unit 2.

[0039] The cooling fan 24 is located on top of the outdoor unit 2 of the air conditioning unit.

[0040] Specifically, the cooling fan 24 is fixedly installed at the top center of the outdoor unit 2 of the air conditioning unit, corresponding to the air outlet 28 on the top of the outdoor unit 2. The exhaust end of the cooling fan 24 completely covers the airflow area of ​​the air outlet 28 to prevent air leakage during exhaust. The cooling fan 24 is an axial flow cooling fan, consisting of fan blades, a drive motor, and a protective mesh cover. The protective mesh cover is fixedly installed at the air outlet 28 of the outdoor unit 2, covering the outside of the cooling fan 24 to prevent foreign objects from entering the fan blade area and causing equipment damage. The drive motor adopts a shock-absorbing mounting structure. Vibration damping pads are added between the top casings of the outdoor unit 2 of the air conditioning unit to effectively reduce vibration and noise during motor operation. The cooling fan 24 works based on the axial flow principle. When the drive motor drives the fan blades to rotate at high speed, a directional negative pressure air field is formed inside the outdoor unit 2 of the air conditioning unit, realizing continuous intake and high-pressure exhaust of indoor air. The characteristics of the axial flow structure give it the advantage of large airflow, which can quickly remove the heat from the condenser and meet the high-efficiency heat dissipation requirements of the condenser. At the same time, the strong airflow generated by its high-speed rotation can form a carrying force, providing power for the discharge of condensate (the discharge of condensate relies on increasing the airflow on the surface).

[0041] The cooling fan 24 draws indoor air into the outdoor unit 2 of the air conditioning unit through the outdoor unit air inlet 21, and after passing through the condenser 25, it exchanges heat with the condenser 25 to remove the heat from the condenser 25, and discharges the water in the condenser 25 into the indoor ceiling through the outdoor unit air outlet 28.

[0042] It should be noted that the condenser 25 is fixedly installed in the core air duct inside the outdoor unit 2 of the air conditioning unit, located between the air inlet 21 of the outdoor unit and the air inlet end of the cooling fan 24. It is a finned tube condenser, which consists of multiple parallel heat exchange copper tubes and heat dissipation fins that are equally spaced and fitted on the outside of the copper tubes. The heat exchange copper tubes are filled with high-temperature and high-pressure refrigerant compressed by the compressor. The heat dissipation fins are made of aluminum, which greatly increases the contact area between the condenser and the air and improves the heat exchange efficiency.

[0043] In addition, the condenser 25 also serves as a drainage structure in this application. Specifically, the top of the condenser 25 is hollowed out; the first pipe 26, which is placed inside the outdoor unit 2 of the air conditioning unit, is suspended above the condenser 25 and has multiple through holes at the bottom; the bottom of the condenser 25 is connected to the water receiving tray 15 through the second pipe 29.

[0044] The pump body 17 pumps water into the first pipe 26 above the condenser 25 through the first pipe 26, and the water drips onto the condenser 25 through the bottom through hole. When the water is not completely discharged, the remaining water is discharged into the water receiving tray 15 through the second pipe 29.

[0045] It should be noted that the first pipe 26 is bent at the condenser 25 inside the outdoor unit 2 of the air conditioning unit, such as at a 90-degree angle, forming a part of the pipe suspended above the condenser 25. The side of the suspended pipe adjacent to the condenser 25 has a through hole, so that the water in the suspended pipe drips out through the through hole and falls onto the condenser 25. While the condenser 25 itself evaporates, the cooling fan 24 can further help increase the air flow on the surface of the water and evaporate the water.

[0046] The bottom of the condenser 25 has a guide channel 23. When water is not completely evaporated, it passes through the condenser 25 and enters the guide channel 23 at the bottom of the condenser 25. The guide channel 23 has a shape that is higher at one end and lower at the other end, so that the water entering the guide channel 23 flows to the lower side due to the potential difference. This side is connected to the second pipe 29, and the water enters the second pipe 29 and is discharged into the water receiving tray 15. This process is repeated to form a water discharge structure.

[0047] In summary, after the radiator fan 24 starts, it creates negative pressure inside the outdoor unit 2 of the air conditioning unit through the axial flow principle. Indoor air is first initially filtered through the grille of the outdoor unit's air inlet 21 (a grille can be installed as needed), then filtered a second time through the outdoor unit's filter screen 22, before entering the outdoor unit 2 and flowing towards the condenser 25. The room-temperature indoor air undergoes thorough heat exchange with the high-temperature, high-pressure refrigerant in the heat exchange copper tubes of the condenser 25. The heat from the refrigerant is absorbed by the air, achieving heat dissipation and cooling of the condenser 25. After heat exchange, the hot air, under the continuous negative pressure suction and pressurization of the radiator fan 24, flows towards the outdoor unit 2. The condensate collected in the drip tray 15 of the indoor unit 1 of the air conditioning unit is pumped quantitatively by the pump body 27 on the first pipe 26 into the condenser 25 of the outdoor unit 2 of the air conditioning unit. It drips onto the condenser 25 through the through hole. As the air intake 21 of the outdoor unit increases the air velocity on its surface, the condensate evaporates and mixes with the hot air flow before being discharged from the air outlet 28 of the outdoor unit into the indoor top area, thus realizing the discharge of condensate. During the whole process, the condensate that is not discharged will pass through the guide groove 23 below the condenser 25, and then through the second pipe 29 into the drip tray 15 to wait to be pumped into the first pipe 26 again.

[0048] Water droplets fall onto the condenser 25, where the water evaporates into water vapor and absorbs heat, thus improving heat exchange efficiency. The cooling fan 24 also aims to improve efficiency and maintain system operation. While improving heat exchange efficiency, it indirectly discharges water as water vapor into the upper indoor space.

[0049] In one embodiment, the cooling air outlet area 3 is composed of the top plate of the indoor unit 1 of the air conditioning unit, the bottom plate of the outdoor unit 2 of the air conditioning unit, the back plate and the front plate of the main body of the air conditioning unit, and at least one cold air outlet 31 is provided on the front plate.

[0050] Specifically, the top plate of the indoor unit 1 of the air conditioning unit serves as the lower boundary of the cooling air outlet area 3, and the bottom plate of the outdoor unit 2 serves as the upper boundary of the cooling air outlet area 3, arranged parallel to the top plate of the indoor unit 1. The back plate of the main body of the air conditioning unit serves as the rear boundary of the cooling air outlet area 3, and can be made of a single piece of sheet metal with the back plates of the indoor unit 1 and the outdoor unit 2. The front plate of the main body of the air conditioning unit serves as the front boundary of the cooling air outlet area 3.

[0051] The cold air delivered by the indoor unit 1 of the air conditioning unit enters the cooling air outlet area 3 through the air guide hood on the top plate of the indoor unit. Since this area is a relatively closed static pressure air cavity formed by the top plate of the indoor unit 1, the bottom plate of the outdoor unit, the main back plate and the front plate of the air conditioning unit, the cold air flows forward along the smooth back plate and the insulated top / bottom plate under the action of the static pressure air cavity. The cold air is then directionally discharged into the indoor activity area through the adjustable cold air outlet 31 on the front plate. The sealing design and insulation treatment of the entire area minimize the loss of cold air and the penetration of hot air, ensuring the accuracy and effectiveness of the cooling of the work area.

[0052] In one embodiment, the cold air outlet 31 is an angle-adjustable air outlet.

[0053] Specifically, there can be two cold air outlets 31, for example, two cold air outlets 31 are arranged horizontally, and each cold air outlet 31 has a cylindrical structure. This structure allows the air delivery distance to be longer. Specifically, the cold air outlet 31 is connected to the cooling air outlet area 3 through a rotating sleeve 32, and the rotating sleeve 32 is used to realize multiple angle adjustments of the cylindrical air outlet.

[0054] In addition, the cold air outlet 31 can also be a louvered air outlet or other adjustable air outlet.

[0055] In one embodiment, a jet-flow air-conditioning unit further includes casters 4, which are disposed on the bottom surface of the unit's main body. The casters 4 facilitate the movement of the jet-flow air-conditioning unit indoors.

[0056] It should be noted that while this application does not describe conventional structures related to air conditioning refrigeration and heat dissipation in the internal structures of the indoor unit 1 and the outdoor unit 2 of the air conditioning unit, these structures are present. Furthermore, the location of the drip tray 15 can be determined based on the location where condensate is generated. This application does not limit the specific location of the drip tray 15 within the indoor unit 1, as long as it can collect condensate. The pump body 27 can be positioned within the drip tray 15 of the indoor unit 1 as needed.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
