Description

Technical Field

[0001] This utility model relates to the field of condensate recovery and humidification devices for outdoor air conditioning units, specifically an outdoor air conditioning unit condensate recovery and humidification device. Background Technology

[0002] An air conditioner outdoor unit is a key piece of equipment that integrates core components such as a refrigeration compressor, condenser, and cooling fan. It is usually installed on the outside of a building and is responsible for transferring heat from the indoor air to the outdoor environment through the circulation of refrigerant to achieve indoor temperature regulation and control. It is an indispensable and important component of the entire air conditioning system to achieve cooling or heating functions. However, current air conditioner outdoor units continuously produce condensate in cooling mode. This condensate is usually discharged directly to the outside through a drain pipe and is not fully utilized. In order to avoid wasting this condensate and effectively improve the operating efficiency and resource utilization of the air conditioning system, a condensate recovery and humidification device is used to cool the outdoor unit, allowing it to operate at a more suitable temperature and extending its service life.

[0003] However, existing air conditioner outdoor unit condensate recovery and humidification devices often only spray water at a single point on the outdoor unit. While this utilizes the condensate to cool the unit to some extent, its limited range of action means it can only cool a localized area. Since critical components like the heat sink fins are widely distributed, areas not covered by the spray remain at higher temperatures. This can lead to poor cooling performance and difficulty in effectively lowering the overall operating temperature of the outdoor unit. Especially during hot summer months, when the outdoor unit operates under high load for extended periods, localized cooling cannot meet its efficient heat dissipation needs, potentially impacting the cooling efficiency and lifespan of the air conditioning system. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide an air conditioner outdoor unit condensate recovery and humidification device to solve the technical problem that the existing air conditioner outdoor unit condensate recovery and humidification devices only use a single fixed-point water spraying method, which has a limited range of action and can only cool a local area of ​​the outdoor unit. As a result, key parts such as heat dissipation fins are not sufficiently cooled, the overall cooling effect is poor, and it cannot meet the high-efficiency heat dissipation requirements when operating under high temperature and high load in summer, thus affecting the cooling efficiency and service life of the air conditioning system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air conditioner outdoor unit condensate recovery and humidification device, including an air conditioner outdoor unit, the air conditioner outdoor unit including a body, a humidification mechanism provided at the top rear of the body, the humidification mechanism including a mounting bracket, the mounting bracket being arranged in a C-shape, and the two ends of the C-shaped mounting bracket being screwed to the top and back of the body respectively, a mounting seat being provided on the inner side of the mounting bracket, a sliding groove being opened on the inner side of the mounting seat, a lead screw being rotatably connected in the sliding groove, a motor being provided on the top of the mounting seat, and the output end of the motor passing through the mounting seat and being fixedly connected to the lead screw;

[0006] A mounting plate is fixedly connected to the lead screw via a lead screw seat. Multiple atomizing nozzles are mounted on the mounting plate, arranged equidistantly from left to right. The back of each atomizing nozzle is connected to a water outlet via a flexible hose.

[0007] By adopting the above technical solution, stable support is achieved through the C-shaped screw connection of the mounting bracket. In conjunction with the screw rod in the slide groove and the motor driving the vertical displacement of the mounting plate, the equidistantly arranged atomizing nozzles form a vertical dynamic scanning spray, breaking through the limitation of single-point spraying, significantly improving the uniformity of coverage of the heat dissipation port and fan port area, and enhancing the cooling effect of the heat dissipation fins.

[0008] Furthermore, the humidification mechanism is made entirely of stainless steel, and the motor is set to start on a timer via an external control terminal, which facilitates the timed up-and-down sliding of multiple atomizing nozzles.

[0009] By adopting the above technical solutions, the humidification mechanism is made of stainless steel, which is resistant to rust and aging and can be used for a long time in high-humidity outdoor environments. The motor is started and stopped at a time via an external control terminal, so that the atomizing nozzle slides up and down at a preset frequency, avoiding local over-humidification caused by continuous spraying, and taking into account both water conservation and uniform cooling requirements.

[0010] Furthermore, a throttling mechanism is bolted to the bottom of the mounting bracket. The throttling mechanism includes a leakage groove, which is fixedly connected to the mounting bracket by bolts via a connecting plate.

[0011] By adopting the above technical solution, the bottom of the mounting frame is fixed with bolts to the leakage groove of the throttling mechanism, forming a detachable condensate collection structure that accurately collects the condensate dripping from the machine body, avoiding the risk of leakage caused by loose installation and improving the reliability of the recycling system.

[0012] Furthermore, the inside of the drain groove is provided with a drainage slope, and a drain pipe interface is provided at the low point of the drainage slope.

[0013] By adopting the above technical solution, the inclined surface of the drainage slope inside the leakage groove guides the water flow to the drainage pipe interface in the low-lying area, forcing the condensate to flow in a specific direction, preventing accumulation, evaporation, or splashing, and improving the recovery rate.

[0014] Furthermore, a treatment water tank can be welded to the bottom of the machine body via a frame, and the treatment water tank includes a tank body.

[0015] By adopting the above technical solutions, the treatment water tank welded to the bottom of the machine body collects condensate nearby, shortens the transportation path and reduces energy loss; the integrated fixing of the tank body and the machine body enhances the anti-tipping resistance and ensures the safety of the equipment in strong wind outdoor environments.

[0016] Furthermore, the top of the box is provided with a box cover, and the top of the box cover is provided with two connecting ports, which are respectively connected to the cold water drain pipe and the drain pipe interface via flexible hoses.

[0017] By adopting the above technical solution, the double pipe ports on the top of the tank cover are connected to the cold energy water drain pipe and the drain pipe interface respectively, realizing multi-source compatible recycling; the sealed cover structure isolates external pollutants from entering and maintains water quality cleanliness.

[0018] Furthermore, a filter cotton plate is provided in the middle of the interior of the box, and filter cotton is placed on top of the filter cotton plate. A high-pressure water pump is provided at the bottom of the box, and the output end of the high-pressure water pump passes through one side of the box and is provided with a water outlet. The water outlet is connected to the atomizing nozzle through a hose. An overflow port is provided in the middle of the other side of the box.

[0019] By adopting the above technical solution, the filter cotton plate intercepts impurities in the water in layers, and the high-pressure water pump provides stable water pressure for the atomizing nozzle; the overflow port automatically discharges excess water to prevent the filter layer from being submerged and failing, and maintains the continuous operation of the system.

[0020] Furthermore, a fan vent is provided at the front end of the machine body, and a heat dissipation vent is provided at the back of the machine body.

[0021] By adopting the above technical solution, the atomizing nozzle dynamically covers the fan opening and heat dissipation opening area, so that the evaporated water mist acts on the heat dissipation airflow channel, enhances the heat exchange efficiency of the fins, and directly improves the air conditioning cooling efficiency.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention solves the technical problems of existing devices that use only a single fixed-point water spraying method, resulting in limited range of action, only local cooling while key parts such as heat dissipation fins are not sufficiently cooled, poor overall cooling effect, and inability to meet the high-efficiency heat dissipation requirements during high-temperature and high-load operation in summer, thus affecting the cooling efficiency and service life of the air conditioning system.

[0024] This invention, through the coordinated operation of a throttling mechanism and a treatment water tank, efficiently collects condensate water via a leak-proof groove and a drainage slope, and centrally directs it into the treatment water tank. The treatment water tank, through a layered filter cotton plate, filters dust and dirt and, in conjunction with a high-pressure water pump, provides purified water. This solves the problems of leakage and splashing during condensate water recovery, as well as the risk of atomizing nozzle blockage due to water pollution. It significantly improves the water resource recycling rate, ensures the purity of the spray water, maintains a stable cooling and humidifying effect, and enhances the heat dissipation reliability of the air conditioning system during long-term operation.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Example 1: A condensate recovery and humidification device for an outdoor air conditioning unit, such as... Figure 1-4As shown, the air conditioner includes an outdoor unit 1, which includes a body 101. A humidifying mechanism 2 is provided at the top rear of the body 101. The humidifying mechanism 2 includes a mounting bracket 201, which is C-shaped. Both ends of the C-shaped mounting bracket 201 are screwed to the top and back of the body 101, respectively. A mounting seat 202 is provided on the inner side of the mounting bracket 201. A sliding groove 203 is provided on the inner side of the mounting seat 202. A lead screw 204 is rotatably connected in the sliding groove 203. A motor 205 is provided on the top of the mounting seat 202, and the output end of the motor 205 passes through the mounting seat 202 and is fixedly connected to the lead screw 204.

[0032] A mounting plate 206 is fixedly connected to the lead screw 204 via a lead screw seat. Multiple atomizing nozzles 207 are installed on the mounting plate 206, arranged equidistantly from left to right. The back of the atomizing nozzles 207 is connected to the water outlet 406 via a flexible hose. The C-shaped structure of the mounting bracket 201 is fixed to the top and back of the body 101 by screws at both ends, providing rigid support against wind and vibration. The motor 205 drives the lead screw 204 to rotate in the slide groove 203 of the mounting base 202, causing the mounting plate 206 and the equidistantly arranged atomizing nozzles 207 on the lead screw seat to move vertically and reciprocally, forming a vertical linear scanning spray pattern. This allows the water mist to dynamically cover the core heat dissipation area between the heat dissipation port 103 and the fan port 102, eliminating the blind spots of traditional fixed-point spraying, ensuring that the heat dissipation fins are in full contact with the evaporative cooling airflow, and significantly improving the heat dissipation efficiency under high-temperature conditions.

[0033] See Figure 3 , Figure 4 The humidification mechanism 2 is made entirely of stainless steel. The motor 205 is set to start on a timer via an external control terminal, which facilitates the timed up-and-down sliding of multiple atomizing nozzles 207. The stainless steel humidification mechanism 2 is resistant to corrosion from condensate and aging from outdoor ultraviolet rays, ensuring the long-term smooth operation of the lead screw 204 within the slide groove 203. The motor 205 is timed and controlled by the external control terminal, periodically driving the atomizing nozzles 207 to slide vertically along the mounting plate 206. Through intermittent dynamic spraying, the water mist is evenly diffused to the heat dissipation port 103 area, avoiding local water accumulation or uneven heat dissipation caused by continuous single-point spraying. At the same time, it reduces the water pump load, achieving a balance between efficient water resource utilization and optimized heat dissipation performance.

[0034] Example 2: See Figure 1 , Figure 4The bottom of the mounting bracket 201 is bolted with a throttling mechanism 3, which includes a drain groove 301. The drain groove 301 is fixedly connected to the mounting bracket 201 by bolts through a connecting plate. The bolted drain groove 301 and the bottom of the mounting bracket 201 form a detachable rigid fixation, ensuring that the drain groove 301 is precisely aligned with the dripping water level at the bottom of the body 101, and efficiently collecting the falling condensate. The modular installation design facilitates disassembly, cleaning or replacement, avoiding leakage or incomplete collection problems caused by the displacement of the drain groove 301 after long-term use, and ensuring the stable operation of the condensate recovery system from the source.

[0035] See Figure 1 , Figure 2 The inside of the drain trough 301 is equipped with a drainage slope 302, and a drain pipe interface 303 is provided at the low point of the drainage slope 302. The sloping structure of the drainage slope 302 causes the condensate in the drain trough 301 to naturally converge to the drain pipe interface 303 at the low point under the action of gravity, forming a non-powered directional flow mechanism, avoiding evaporation loss or dust deposition caused by water stagnation in the trough; the centralized flow design eliminates the risk of water splashing, ensuring that all condensate is transported to the treatment water tank 4 through the hose, significantly improving the efficiency of water resource recycling.

[0036] See Figure 3 , Figure 4 The bottom of the unit 101 can be welded with a treatment water tank 4 via a frame. The treatment water tank 4 includes a housing 401. The treatment water tank 4 welded to the bottom frame forms an integral structure with the unit 101, which greatly shortens the flow distance of condensate from the throttling mechanism 3 to the housing 401, reducing the transport resistance and water pump energy consumption. The rigid connection design improves the overall center of gravity stability of the equipment, resists the risk of vibration or tipping caused by the high load of the mounting frame 201, and ensures the safety of the outdoor unit in strong wind conditions.

[0037] See Figure 1 The top of the housing 401 is provided with a cover 402, and the top of the cover 402 is provided with two connecting ports 403. The two connecting ports 403 are connected to the cold water drain pipe and the drain pipe interface 303 respectively through hoses. The two connecting ports 403 are simultaneously connected to the cold water drain pipe and the drain pipe interface 303 through hoses, allowing the air conditioning condensate and other cold source wastewater to be recycled in a unified manner. The closed design of the cover 402 prevents dust and insects in the air from entering the housing 401, prevents the water filter cotton 7 from clogging or secondary pollution of the water, ensures the cleanliness of the water supplied by the subsequent atomizing nozzle 207, and extends the service life of the core components.

[0038] See Figure 1 , Figure 2Inside the housing 401, a filter cotton plate 404 is installed in the middle, and filter cotton is placed on top of the filter cotton plate 404. A high-pressure water pump 405 is installed at the bottom of the housing 401, and the output end of the high-pressure water pump 405 passes through one side of the housing 401 and is provided with a water outlet 406. The water outlet 406 is connected to the atomizing nozzle 207 through a hose. An overflow port 407 is opened in the middle of the other side of the housing 401. The filter cotton on the filter cotton plate 404 performs gradient physical filtration on the introduced condensate, effectively adsorbing grease and particulate matter. The high-pressure water pump 405 draws purified water from the bottom of the housing 401, pressurizes it and delivers it to the water outlet 406 to ensure the jet pressure required by the atomizing nozzle 207. The overflow port 407 on the side wall automatically overflows when the water level exceeds the height of the filter cotton plate 404, avoiding filter layer immersion failure and water pump dry running damage, and ensuring that the system continuously and stably outputs purified spray under extreme rainfall.

[0039] See Figure 1 , Figure 4 The front of the unit 101 is provided with a fan vent 102, and the back of the unit 101 is provided with a heat dissipation vent 103. Through the convection of the air intake airflow of the fan vent 102 and the heat exhaust airflow of the heat dissipation vent 103, the water curtain sprayed by the atomizing nozzle 207 accurately covers the core heat dissipation area. Under the drive of the airflow, the water mist penetrates into the gap between the heat dissipation fins and quickly evaporates and absorbs heat, significantly reducing the fin temperature and the compressor return air temperature. The targeted humidification design maximizes the use of condensate cooling energy, breaks through the traditional high temperature heat dissipation bottleneck of outdoor units, and improves the energy efficiency ratio and service life of the air conditioning system.

[0040] The implementation principle of this embodiment is as follows: First, the condensate generated during the air conditioner's cooling operation drips naturally from the bottom of the unit 101 and is collected by the throttling mechanism 3 fixed to the bottom of the mounting bracket 201. Specifically:

[0041] The drain trough 301 is rigidly connected to the mounting bracket 201 by bolts. The drainage slope 302 inside it adopts a sloping structure to force the water flow to converge to the drainage pipe interface 303 in the low-lying area.

[0042] The drain pipe interface 303 is connected to the pipe inlet 403 on the top of the treatment water tank 4 via a flexible hose, forming a splash-proof directional drainage channel to prevent condensate from escaping.

[0043] Subsequently, the condensate enters the tank 401 of the treatment tank 4 through the inlet 403, where it undergoes a physical purification and pressurization process.

[0044] Water flows through the filter cotton laid on the 404 filter cotton plate, and intercepts impurities such as dust and oil through a gradient adsorption mechanism;

[0045] The purified water settles at the bottom of the tank 401. The high-pressure water pump 405 pressurizes the water to the set pressure value and outputs it through the outlet 406.

[0046] The overflow port 407 is located in the middle of the side wall of the box 401. When the water level exceeds the height of the filter cotton plate 404, it will automatically overflow to avoid clogging of the filter layer.

[0047] Finally, the high-pressure water flows through the hose to the atomizing nozzle 207 of the humidification unit 2, performing dynamic coverage humidification:

[0048] The motor 205 is started at regular intervals via an external control terminal, driving the lead screw 204 to rotate within the slide groove 203 of the mounting base 202;

[0049] The lead screw 204 drives the mounting plate 206 on the lead screw seat to move vertically, causing multiple atomizing nozzles 207 arranged at equal intervals from left to right to slide back and forth along the direction of the heat dissipation port 103.

[0050] The atomized water curtain evenly covers the heat dissipation vent 103 on the back of the body 101 and the fan vent 102 at the front, significantly reducing the temperature of the heat dissipation fins through evaporative heat absorption.
