Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an evaporative cooling low-carbon energy-saving air conditioner. Background Technology

[0002] Existing air conditioners typically use a compressor to drive refrigerant, drawing indoor air into the air conditioner, cooling it, and then re-entering the room. However, the compressor consumes a significant amount of electricity, resulting in high operating costs. An existing application (CN202211003474.2) describes an evaporative cooling, low-carbon, energy-saving air conditioner, comprising an evaporator shell, evaporator plates, spray pipes, and a centrifugal drying fan. The evaporator shell forms an evaporation chamber… As water flows from a high point to a low point, it impacts the air flowing from a low point (air inlet) to a high point (air outlet). This opposing motion creates a high relative velocity, significantly increasing the amount of water vapor generated per unit volume of water, thus ensuring a large cooling capacity. However, this device requires two water pumps for water injection and drainage. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that require two water pumps for water injection and drainage, and to propose an evaporative cooling, low-carbon, and energy-saving air conditioner.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an evaporative cooling low-carbon energy-saving air conditioner, including an evaporator shell, a centrifugal drying fan, an air outlet, a spray pipe, an evaporator coil, an evaporator plate, and an air inlet. A water pump is fixedly installed on the outer wall of the evaporator shell, and the water outlet of the water pump is connected to the spray pipe located above the evaporator plate through a pipe. A square tube is fixedly installed at the bottom of the evaporator shell, and both ends of the square tube penetrate and extend into the evaporator shell. The water inlet of the water pump is connected to the square tube through a pipe, and the other end of the square tube is connected to a water inlet pipe connected to a water source. A receiving plate is provided above the square tube, and the outer wall of the receiving plate is fixedly connected to the evaporator shell. Both the upper end face of the square tube and the receiving plate are provided with through holes, and a recovery pipe is welded to the through holes. A float plate is raised and lowered above the receiving plate through a guide device, and the float plate is located directly above the recovery pipe. A one-way valve that only allows water to flow from top to bottom is fixedly installed inside the recovery pipe.

[0006] Preferably, the guiding device includes limiting posts and retaining rings. A plurality of limiting posts are fixedly provided on the top of the receiving plate, and the upper end of the limiting posts passes through and is slidably connected to the floating plate. The top of the limiting posts is threadedly connected to the retaining rings, and the retaining rings are located above the floating plate.

[0007] Preferably, a sealing ring is bonded to the lower end face of the float plate, a sealing ring groove that mates with the sealing ring is provided on the upper end face of the receiving plate, and an outer chamfer and an inner chamfer are provided at the lower end of the sealing ring to facilitate insertion into the sealing ring groove.

[0008] Preferably, the outer edge of the receiving plate is bent upward into a funnel-shaped section, and the uppermost end is located below the air inlet.

[0009] Preferably, a filter screen located above the float plate is fixed on the inner wall of the funnel section of the receiving plate.

[0010] Preferably, the float is made of foam board, and the outer wall of the foam board is covered with a lightweight protective shell.

[0011] Preferably, the foam board has an air bladder inside, and the air bladder is filled with hydrogen gas.

[0012] The present invention proposes an evaporative cooling low-carbon energy-saving air conditioner, the beneficial effects of which are: when in use, the device can collect the unevaporated water sprayed from the spray pipe through the receiving plate and the water falling through the evaporation plate and inject it into the square pipe so that the water pump can re-inject it into the spray pipe, thereby recycling some of the excess spray water in real time, requiring less water to be injected, and the injection of spray water and the discharge of excess water can be completed by only one water pump.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5 An evaporative cooling low-carbon energy-saving air conditioner includes an evaporator shell 1, a centrifugal drying fan 2, an air outlet 3, a spray pipe 5, an evaporator coil 8, an evaporator plate 9, and an air inlet 10. A water pump 6 is fixedly installed on the outer wall of the evaporator shell 1, and the outlet of the water pump 6 is connected to the spray pipe 5 located above the evaporator plate 9 through a pipe. A square pipe 7 is fixedly installed at the bottom of the evaporator shell 1, and both ends of the square pipe 7 penetrate and extend into the evaporator shell 1. The inlet of the water pump 6 is connected to the square pipe 7 through a pipe. The other end of the square tube 7 is connected to the water inlet pipe 12 connected to the water source. A receiving plate 11 is provided above the square tube 7, and the outer wall of the receiving plate 11 is fixedly connected to the evaporation shell 1. Both the square tube 7 and the receiving plate 11 have through holes on their upper surfaces, and a recovery pipe 17 is welded to the through holes. A float plate 14 is raised and lowered above the receiving plate 11 through a guide device, and the float plate 14 is located directly above the recovery pipe 17. A one-way valve 16 that only allows water to flow from top to bottom is fixedly installed inside the recovery pipe 17.

[0021] Reference Figure 3-4 In order to ensure that the float 14 can only move up and down in a straight line and will not detach, the guide device includes a limiting post 15 and a retaining ring. Several limiting posts 15 are fixedly provided on the top of the receiving plate 11, and the upper end of the limiting post 15 passes through and is slidably connected to the float 14. The top of the limiting post 15 is threadedly connected to the retaining ring, and the retaining ring is located above the float 14.

[0022] Reference Figure 3-4 To prevent water and air from seeping in after the float plate 14 descends and closes the recovery pipe 17, a sealing ring 19 is bonded to the lower end face of the float plate 14. A sealing ring groove 18 that matches the sealing ring 19 is provided on the upper end face of the receiving plate 11. The lower end of the sealing ring 19 is provided with an outer chamfer and an inner chamfer to facilitate insertion into the sealing ring groove 18.

[0023] Reference Figure 3-4 In order to collect water in a concentrated manner to increase the buoyancy of the float plate 14, the outer side of the receiving plate 11 is bent upward into a funnel-shaped section, and the uppermost end is located below the air inlet 10.

[0024] Reference Figure 3-4 In order to prevent impurities absorbed by the water in contact with the air from accumulating and affecting the sealing of the float plate 14 to the recovery pipe 17, a filter screen 13 located above the float plate 14 is fixed on the inner wall of the funnel section of the receiving plate 11.

[0025] Reference Figure 3-5 In order to improve the buoyancy of the float 14, the float 14 is made of foam board 21, and the outer wall of the foam board 21 is covered with a lightweight protective shell 20.

[0026] Reference Figure 3-5 In order to further improve the buoyancy of the float 14, the foam board 21 is provided with an air bladder 22, and the air bladder 22 is filled with hydrogen gas 23.

[0027] Working principle: Unevaporated water sprayed from the spray pipe 5 falls onto the receiving plate 11 through the evaporation plate 9. The water pump 6 draws in water from the receiving plate 11 that enters the square pipe 7 through the recovery pipe 17 and water that enters the square pipe 7 through the inlet pipe 12, and injects it into the spray pipe 5. When there is no water on the receiving plate 11, the float 14 loses buoyancy and descends under the action of gravity to close the recovery pipe 17, preventing air from entering and ensuring that only the inlet pipe 12 injects water into the square pipe 7. When the water on the receiving plate 11 accumulates to a certain level, the float 14 rises again under the action of buoyancy to open the recovery pipe 17, allowing water to enter the square pipe 7 for recycling.

[0028] When in use, the device can collect the unevaporated water sprayed from the spray pipe 5 through the receiving plate 11 and the water falling through the evaporation plate 9 and inject it into the square pipe 7 so that the water pump 6 can re-inject it into the spray pipe 5. This allows for the immediate recycling of some of the excess spray water, requiring less water to be injected. Moreover, the injection of spray water and the discharge of excess water can be completed with just one water pump 6.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
