Description

Technical Field

[0001] This utility model relates to the field of warehouse air conditioning technology, specifically a water-cooled warehouse air conditioner equipped with a condensate recovery mechanism. Background Technology

[0002] Maintaining suitable temperature and humidity is crucial for the preservation of goods in warehousing. Therefore, air conditioning is usually installed in warehouses to maintain the temperature and humidity. However, in the process of traditional air conditioning systems, when hot air passes through the evaporator, the water vapor in the air condenses into water droplets due to heat exchange. These water droplets are called condensate. Air conditioning systems produce a large amount of condensate during operation, which is usually discharged directly to the outside, resulting in a waste of water resources and increased operating costs. Utility Model Content

[0003] The purpose of this invention is to provide a water-cooled warehouse air conditioner with a condensate recovery mechanism to solve the problem of waste caused by the direct discharge of condensate in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled warehouse air conditioner with a condensate recovery mechanism, comprising an inner casing, which is fixedly installed on the top of the warehouse, and a motor-driven air impeller is rotatably installed inside the inner casing. A water tank assembly is placed on the warehouse floor on one side of the inner casing, and a water-cooled unit is fixedly placed on the ground on one side of the water tank assembly. A condensation tower shell is fixedly installed on the ground outside the warehouse on one side of the water-cooled unit. An evaporative heat exchange fin is fixedly installed inside the inner casing, and the pipes of the evaporative heat exchange fin are connected to one side of the water-cooled unit. A collection mechanism is provided between the evaporative heat exchange fin and the water tank assembly, through which the condensate generated during heat exchange can be collected for subsequent use.

[0005] Preferably, the collection mechanism includes: a water collection tray, which is fixedly installed inside the inner casing, and the side surface of the inner casing is penetrated by the pipes of the evaporative heat exchange plate. The water collection tray is located below the evaporative heat exchange plate, and the evaporative heat exchange plate is on one side of the motor air impeller. The interior of the water collection tray is designed to be inclined, and a water outlet is opened at the lower end of the water collection tray. The water outlet of the water collection tray is connected to the water tank assembly. A first water level detector is fixedly installed on the outer surface of the water tank assembly, and the detection end of the first water level detector passes through the outer surface of the water tank assembly.

[0006] Using the above technical solution, when the water-cooled unit is running, the chilled water in the evaporative heat exchanger will circulate. When the motor blower impeller rotates to circulate the air in the storage chamber, it can circulate and exchange heat with the air passing through the inner casing. The large amount of condensate generated during heat exchange can drip into the inside of the water collection pan. The inclined design of the water collection pan allows the condensate to be guided and discharged into the water tank assembly. The water level detector can monitor the water level on one side of the water tank assembly in real time, so that the condensate can be collected and not discharged directly to the outside, reducing the waste of water resources.

[0007] Preferably, the interior of the water tank assembly is divided into two parts, and a water inlet is provided at one end of the water tank assembly near the first water level detector. The interior of the water tank assembly is equipped with an extraction and filtration mechanism to filter the injected water and condensate, so that bacteria and impurities will not enter the other side of the water tank assembly, reducing the chance of scale and blockage during use.

[0008] By adopting the above technical solution, water can be easily replenished into the water tank through the water inlet, allowing the water to be replenished. At the same time, the injected water and condensate can be filtered to remove impurities and microorganisms that may be present in the water, reducing the chance of pipe blockage and scale adhesion to the inner wall, and improving the efficiency of heat exchange during condenser heat exchange.

[0009] Preferably, the extraction and filtration mechanism includes: a filter screen assembly, which is snap-fitted into the interior of the water tank assembly, and the inner surface of the water tank assembly is in close contact with the outer surface of the filter screen assembly. A suction pump is fixedly installed inside the water tank assembly, and the suction pump is located on the side of the filter screen assembly away from the first water level detector.

[0010] By adopting the above technical solution, the water inside the water tank can be filtered in multiple layers through the filter screen group. This allows the water to pass through the filter screen group to remove impurities and bacteria. A portion of the filtered water can be pumped to the other side of the water tank group through a suction pump. This filtered water is then supplied to the evaporative heat exchange fins for use, and is used to replenish the cooling water for the condenser heat exchange fins. The heat exchange capacity can be increased by setting up the water tank group.

[0011] Preferably, a one-way valve and a water pump assembly are fixedly installed on the outer surface of one end of the water tank assembly, and the pipes of the one-way valve and the water pump assembly pass through the outer shell of the condensing tower. A second water level detector is fixedly installed on the end of the water tank assembly away from the first water level detector, and one end of the second water level detector passes through the outer surface of the water tank assembly. The outer surface of the water tank assembly near the second water level detector is connected to the other end of the water-cooled unit, and the end of the water tank assembly near the second water level detector is connected to the outer shell of the condensing tower.

[0012] By adopting the above technical solution, the water level on one side of the water tank group can be monitored by the second water level detector. After the water level drops below the set height, the suction pump is started to facilitate the replenishment of cooling water during evaporation. The cooling water can also be used for heat exchange and circulation through the water-cooled unit, allowing the cooling water that has absorbed heat to enter the interior of the condenser tower shell for cooling and heat dissipation.

[0013] Preferably, a fan motor is fixedly installed inside the condensing tower shell, and the fan motor and the condensing tower shell are designed concentrically. A condensing heat exchange plate is fixedly installed inside the condensing tower shell, and the condensing heat exchange plate is connected to the water-cooled unit and the water tank assembly respectively. A rotating engagement mechanism is provided between the condensing tower shell and the fan motor. The rotating engagement mechanism facilitates heat dissipation of the condensing heat exchange plate and accelerates the heat dissipation speed of the condensing heat exchange plate.

[0014] Using the above technical solution, the rotation of the fan motor can draw external air into the interior of the condensing tower shell, allowing the air to dissipate heat through the condensing heat exchange fins. At the same time, the rotation of the one-way valve and water pump assembly can extract water and condensate from the water tank and discharge it into the spray assembly. The water sprayed by the spray assembly can pass through the condensing heat exchange fins and wet them. Combined with the rotation of the fan motor, the heat dissipation speed of the condensing heat exchange fins is accelerated. When the interior of the condensing tower shell is short of water, water can be sprayed directly from the top to replenish the water, while simultaneously wetting the condensing heat exchange fins.

[0015] Preferably, the rotating meshing mechanism includes: a gear connecting shaft, which is rotatably installed inside the condensing tower shell, and the condensing tower shell and the gear connecting shaft are concentrically designed, and the gear connecting shaft is connected to a fan motor; a pump body is fixedly installed inside the condensing tower shell, and a connecting gear is fixedly installed on the outer surface of the pump body's rotating shaft, the connecting gear meshes with the gear connecting shaft, and the diameter of the gear connecting shaft is larger than the diameter of the connecting gear; a spray assembly is fixedly installed inside the condensing tower shell, and the spray assembly is connected to the pump body, and the pump body is connected to the spray assembly; the spray assembly is connected to a one-way valve and a water pump assembly.

[0016] Using the above technical solution, when the fan motor rotates, it will drive the gear connecting shaft to rotate as well, so that the connecting gear meshing with the gear connecting shaft can rotate along with it, and the connecting gear can drive the pump body to operate, drawing water from the bottom of the condenser tower shell and spraying it out again from the spray assembly. At the same time, through the diameter difference between the gear connecting shaft and the connecting gear, the rotation speed of the pump body is accelerated, allowing the spray assembly to spray out more water and improve the heat dissipation effect of the condenser heat exchanger.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the water-cooled warehouse air conditioner equipped with a condensate recovery mechanism:

[0018] 1. When the air conditioner is running, the chilled water in the evaporator heat exchanger will circulate through the water-cooled unit, so that the chilled water is at a low temperature when it enters the interior of the evaporator heat exchanger. At the same time, the rotation of the motor's blower impeller will draw air from the warehouse into the inner casing for circulation, so that the air is cooled as it passes through the evaporator heat exchanger. Meanwhile, the water vapor in the air will condense on the outer surface of the evaporator heat exchanger and fall into the water collection pan. The inclined design of the water collection pan will drain the water into the interior of the water tank assembly, so that the condensed water will not be discharged directly but will be collected directly into the water tank assembly. The condensate collected in the water tank assembly can be used in the outer shell of the condensation tower and the condensation heat exchanger, so that the condensate can be utilized and water resources can be wasted.

[0019] 2. After the condensate is injected into the water tank assembly, the water level in the tank assembly will rise. The water level can be monitored by the first water level detector. During the process of the water rising, the water will also be filtered through the filter screen assembly. When the second water level detector detects that the water level on the other side of the water tank assembly is lower than the set value, the filtered water can be injected into the other side of the water tank assembly by the suction pump. This allows the water and condensate to be filtered and injected into the other side of the water tank assembly, so that the condenser heat exchanger can be used. It also allows the impurities and bacteria in the condensate to be filtered, reducing the chance of scale and blockage during the use of the condenser heat exchanger, and preventing the condenser heat exchanger from being affected by scale.

[0020] 3. During heat dissipation, the fan motor rotates and draws outside air into the condenser tower shell. Simultaneously, the condenser heat exchange fins absorb heat from the water-cooled unit and dissipate it through water sprayed by the spray assembly. When the water level inside the condenser tower shell is low, the one-way valve and water pump assembly will activate to extract the water and condensate stored in the water tank and send the condensate into the spray assembly. This ensures that when replenishing water to the condenser tower shell, the water is sprayed from the top rather than injected from the bottom. Simultaneously, the rotation of the fan motor drives the gear connecting shaft to rotate, allowing the connecting gear meshing with the gear connecting shaft to rotate as well. Based on the diameter difference between the connecting gear and the gear connecting shaft, the pump body can rotate faster. This allows the fan motor to dissipate heat while simultaneously pumping water into the spray assembly, accelerating the pumping out of the water, increasing the pumped water volume, improving the heat dissipation speed of the condenser heat exchange fins, and enabling the condensate to be reused.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a water-cooled warehouse air conditioner with a condensate recovery mechanism, including an inner casing 1, which is fixedly installed on the top of the warehouse, and a motor-driven air impeller 2 is rotatably installed inside the inner casing 1. A water tank assembly 6 is placed on the warehouse floor on one side of the inner casing 1, and a water-cooled unit 5 is fixedly placed on the ground on one side of the water tank assembly 6. A condensation tower shell 12 is fixedly installed on the ground outside the warehouse on one side of the water-cooled unit 5. An evaporative heat exchange fin 4 is fixedly installed inside the inner casing 1, and the pipes of the evaporative heat exchange fin 4 are connected to one side of the water-cooled unit 5. A collection mechanism is provided between the evaporative heat exchange fin 4 and the water tank assembly 6. The condensate generated during heat exchange can be collected by the collection mechanism for subsequent use.

[0030] The inner casing 1 is fixed to the top of the warehouse, which allows the delivered air to be sent to a farther distance. At the same time, the rising hot air can be more easily drawn into the interior of the inner casing 1 by the motor-driven air impeller 2 for circulation.

[0031] The collection mechanism includes: a water collection tray 3, which is fixedly installed inside the inner casing 1, and the side surface of the inner casing 1 is penetrated by the pipes of the evaporative heat exchange plate 4. The water collection tray 3 is located below the evaporative heat exchange plate 4, and the evaporative heat exchange plate 4 is on one side of the motor air impeller 2. The interior of the water collection tray 3 is designed to be inclined, and a water outlet is opened at the lower end of the water collection tray 3. The water outlet of the water collection tray 3 is connected to the water tank assembly 6. A first water level detector 7 is fixedly installed on the outer surface of the water tank assembly 6, and the detection end of the first water level detector 7 passes through the outer surface of the water tank assembly 6.

[0032] When cooling is in operation, the chilled water in the water-cooled unit 5 circulates inside the evaporative heat exchange plate 4. With the rotation of the motor-driven air impeller 2, the air supplied to the inner casing 1 can exchange heat through the evaporative heat exchange plate 4. When the air passes through the evaporative heat exchange plate 4, the water vapor in the air will condense on the surface of the evaporative heat exchange plate 4 and fall into the water collection pan 3. The inclined design of the water collection pan 3 allows the water to be guided and completely discharged into the water tank assembly 6. At the same time, the first water level detector 7 on the outer surface of the water tank assembly 6 monitors the water and condensate stored inside one end of the water tank assembly 6, so that the condensate can be discharged into the water tank assembly 6 for recycling and can be used in the condensing heat exchange plate 17 and the condensing tower shell 12, so that the condensate can be recycled and reused to reduce the waste of water resources.

[0033] The interior of the water tank assembly 6 is divided into two parts, and a water inlet is provided at the end of the water tank assembly 6 near the first water level detector 7. The interior of the water tank assembly 6 is equipped with a suction and filtration mechanism, which filters the injected water and condensate water to prevent bacteria and impurities from entering the other side of the water tank assembly 6, thereby reducing the chance of scale and blockage during use.

[0034] The water level inside the water tank assembly 6 can be monitored by the first water level detector 7. When the water level inside the water tank assembly 6 is low, it can be replenished through the water inlet.

[0035] The extraction and filtration mechanism includes: a filter screen group 8, which is snapped into the inside of the water tank group 6, and the inner surface of the water tank group 6 is in close contact with the outer surface of the filter screen group 8. A suction pump 9 is fixedly installed inside the water tank group 6, and the suction pump 9 is located on the side of the filter screen group 8 away from the first water level detector 7.

[0036] As the water level on one side of the water tank assembly 6 rises, the water level on the other side of the filter assembly 8 also rises accordingly. This allows the filter assembly 8 to filter out the condensate and impurities and bacteria in the water. When the suction pump 9 replenishes water to the other side of the water tank assembly 6, impurities and bacteria cannot enter the other side of the water tank assembly 6. This also prevents scale buildup from forming on the condenser heat exchange plate 17 during heat exchange and circulation, thus avoiding blockage or reduced heat exchange efficiency.

[0037] A one-way valve and a water pump assembly 11 are fixedly installed on the outer surface of one end of the water tank assembly 6, and the pipes of the one-way valve and the water pump assembly 11 pass through the outer shell 12 of the condensing tower. A second water level detector 10 is fixedly installed on the end of the water tank assembly 6 away from the first water level detector 7, and one end of the second water level detector 10 passes through the outer surface of the water tank assembly 6. The outer surface of the water tank assembly 6 near the second water level detector 10 is connected to the other end of the water-cooled unit 5. The end of the water tank assembly 6 near the second water level detector 10 is connected to the outer shell 12 of the condensing tower.

[0038] The second water level detector 10 can monitor the water level on the other side of the water tank assembly 6. When the water level drops to the set height, the suction pump 9 will send the filtered water to the other side of the water tank assembly 6 to replenish the water, so as to eliminate the small amount of evaporation of the internal cooling water when the condenser heat exchange plate 17 is used.

[0039] A fan motor 13 is fixedly installed inside the condenser tower shell 12, and the fan motor 13 and the condenser tower shell 12 are designed concentrically. A condenser heat exchange plate 17 is fixedly installed inside the condenser tower shell 12, and the condenser heat exchange plate 17 is connected to the water-cooled unit 5 and the water tank group 6 respectively. A rotating engagement mechanism is provided between the condenser tower shell 12 and the fan motor 13. The rotating engagement mechanism facilitates the heat dissipation of the condenser heat exchange plate 17 and accelerates the heat dissipation speed of the condenser heat exchange plate 17.

[0040] As the heat inside the circulating water chiller unit 5 is circulated into the condenser heat exchanger 17, the fan motor 13 will rotate to draw cold air from outside into the condenser tower shell 12. Water sprayed by the spray assembly 18 will moisten the condenser heat exchanger 17. The rotation of the fan motor 13 will accelerate the heat dissipation of the condenser heat exchanger 17. At the same time, when the water level inside the condenser tower shell 12 is low, the one-way valve and water pump assembly 11 will be activated to pump the water collected inside the water tank assembly 6 and the condensate into the spray assembly 18 and spray it outward to replenish the water inside the condenser tower shell 12, instead of replenishing the water from the bottom. While replenishing the water inside the condenser tower shell 12, the condenser heat exchanger 17 will also be moistened to dissipate heat.

[0041] The rotating meshing mechanism includes: a gear connecting shaft 14, which is rotatably installed inside the condensing tower shell 12, and the condensing tower shell 12 and the gear connecting shaft 14 are concentrically designed. The gear connecting shaft 14 is connected to the fan motor 13. A pump body 15 is fixedly installed inside the condensing tower shell 12, and a connecting gear 16 is fixedly installed on the outer surface of the rotating shaft of the pump body 15. The connecting gear 16 meshes with the gear connecting shaft 14, and the diameter of the gear connecting shaft 14 is larger than the diameter of the connecting gear 16. A spray assembly 18 is fixedly installed inside the condensing tower shell 12, and the spray assembly 18 is connected to the pump body 15. The pump body 15 is connected to the spray assembly 18, and the spray assembly 18 is connected to the one-way valve and the water pump assembly 11.

[0042] When the fan motor 13 rotates, it drives the gear connecting shaft 14 to rotate as well, so that the connecting gear 16 meshing with the gear connecting shaft 14 can rotate along with it. Through the diameter difference between the connecting gear 16 and the gear connecting shaft 14, the pump body 15 can rotate more quickly, increasing the speed at which water is pumped into the spray assembly 18, allowing the spray assembly 18 to spray out more water, increasing the heat dissipation speed of the condenser heat exchange fins 17, and allowing the spray assembly 18 to spray water outward for cooling while the fan motor 13 is rotating to dissipate heat.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
