[0010] Further improvement measures are: the sprayer is arranged in the annular air duct between the cylindrical honeycomb structure and the wind wheel, or the sprayer is arranged in the inner cavity of the wind wheel, or the sprayer is arranged at the air inlet.

[0011] Further improvement measures are as follows: the wind wheel is a multi-blade centrifugal impeller, the shaft of the wind wheel is driven to rotate by a motor, the wind wheel is connected to the motor by shaft connection or transmission belt connection, and a small gap is left between the wind wheel and the housing and the bottom plate.

[0028] The present invention is described in detail below with reference to specific embodiments.

[0029] Example 1: Figure 1 , Figure 2 and Figure 7 As shown, a water vaporization refrigeration air conditioner with multi-sided air outlet includes a shell 1 and its bottom plate 13, an air inlet 11, an air outlet 12, a honeycomb body 2, a wind wheel 3, a sprayer 4 and a water inlet 41. The air inlet 11 is arranged at the upper position of the shell 1, and the air outlet 12 is arranged at the four side positions of the shell 1. The honeycomb body 2 is located in the shell, and the honeycomb body 2 is surrounded by a polygonal cylindrical honeycomb structure and stands upright on the bottom plate 13. The wind wheel 3 is located in the inner cavity of the cylindrical honeycomb structure. The air entering from the air inlet 11 first enters the inner cavity 5 of the wind wheel 3 and then passes through the honeycomb pores of the honeycomb body 2 and then flows out from the air outlet 12. The sprayer 4 is arranged on the air flow channel in front of the air inlet surface of the honeycomb body 2, and the sprayer 4 is connected to the water inlet 41.

[0030] In this example, the housing 1 is a quadrilateral when viewed from above, and air outlets 12 are arranged on all sides of the housing 1 in all directions.

[0031] In this example: the honeycomb body 2 is made of sintered zeolite molecular sieve material, has a developed pore structure and a huge specific surface area, and has good water absorption.

[0032] In this example, the air inlet 11 is connected to the inner cavity 5 of the fan wheel 3.

[0033] In this example: the sprayer 4 is arranged in the annular air duct 6 between the cylindrical honeycomb structure and the wind wheel 3 on the air flow channel in front of the air inlet surface of the honeycomb body 2.

[0034] In this example: the wind wheel 3 is a multi-blade centrifugal impeller, whose shaft is driven to rotate by a motor 31 , and the connection between the wind wheel 3 and the motor 31 is an axial connection, and a small gap 7 is left between the wind wheel 3 and the housing 1 and the bottom plate 13 .

[0035] In this example: the sprayer 4 is connected to the water inlet 41, and the water supply device connected to the water inlet 41 is an external water pump.

[0036] In this example: a temperature and humidity sensor 71 is provided near the air outlet 11 .

[0037] In this example: the bottom plate 13 is provided with a drainage port 44 .

[0038] Working principle: Figure 1 , Figure 2 and Figure 7 As shown, the working process of the present invention is as follows: the motor 31 is started to drive the wind wheel 3 to rotate, and the external water pump is started at the same time to supply water to the sprayer 4, and the sprayer arranged on the air inlet surface of the honeycomb body 2 sprays water mist to the honeycomb body, and the water mist enters the honeycomb body with the help of the wind force of the wind wheel and is absorbed, and the excess or splashed water of the spray will flow down and be discharged through the drainage port 44 arranged on the bottom plate 13. Driven by the wind wheel, the external air is sucked into the inner cavity 5 of the wind wheel from the air inlet 11, and then enters the annular air duct 6 by the centrifugal force and further disperses the water mist, and then the water mist is converted from liquid to gas after passing through the honeycomb pores with the wind and absorbs the heat of the honeycomb body, and the air is cooled by the honeycomb body in this process and discharged from the air outlet.

[0039] This example does not use traditional axial flow fans and centrifugal fans, but uses multi-blade centrifugal impellers. The advantage is that when the multi-blade centrifugal impeller rotates, the air entering its inner cavity is evenly diffused 360° from top to bottom to the horizontal plane through the centrifugal force, avoiding the use of fans to send air at the air inlet, resulting in wind force concentrated at the bottom of the inner cavity, resulting in weak wind force at the top and strong wind at the bottom. After leaving the wind wheel, the air is fully mixed and dispersed with the water mist sprayed by the sprayer, making the water mist entering each honeycomb more uniform, ensuring that the humidity of the honeycomb in each area is relatively consistent, and the air is cooled after passing through the honeycomb, and finally flows out from the air outlets in all directions.

[0040] The sprayer 4 and the motor 31 in this example are both arranged at the air inlet 11. The design of the air inlet is shown in the attached figure. Figure 7 A structural member 14 with a smaller windshield area is installed at the air inlet. An axial hole 16 and a bolt hole 15 for fixing the motor 31 or the bearing seat are provided in the middle of the structural member. External air can enter the inner cavity 5 of the wind wheel 3 through the air inlet 11.

[0041] The air cooling process in this example is carried out in the honeycomb body. The water mist sprayed by the sprayer is absorbed by the honeycomb body, and the internal airflow desorbs the water in the moist zeolite molecular sieve material. During desorption, the volatilization of water vapor absorbs heat. Since the honeycomb body has a large wind-through expansion area and the dense capillaries formed by the countless open microporous structures inside it accelerate the penetration of internal water to the outside, and the molecular sieve material has an extremely high specific surface area, the water in the molecular sieve can quickly penetrate and vaporize after the superposition of these factors, forming efficient heat exchange conditions. The water vapor vaporization phase change absorbs heat to cool the honeycomb body, so that the air flowing through the honeycomb body can be cooled.

[0042] In this example, a temperature and humidity sensor 71 is provided near the air outlet 12. The sensor monitors and controls the outlet air temperature in cooperation with an external controller. The external controller controls the outlet air temperature and humidity by controlling the water spray volume of the sprayer.

[0043] This embodiment adopts four-sided air outlet to greatly increase the diffusion area of ​​cold air. The wind force at the air outlet is relatively gentle, and a single wind wheel is used to drive the air, and its operating noise is very low, which is suitable for indoor installation model design.

[0044] Example 2: Figure 3 , Figure 4 and Figure 7 As shown, a water vaporization refrigeration air conditioner with multi-sided air outlet includes a housing 1 and its bottom plate 13, an air inlet 11, an air outlet 12, a honeycomb body 2, a wind wheel 3, a sprayer 4 and a water inlet 41; the air inlet 11 is arranged at the upper position of the housing 1, and the air outlet 12 is arranged at the side position of the housing 1; the honeycomb body 2 is located in the housing, and the honeycomb body 2 forms a polygonal cylindrical honeycomb structure standing on the bottom plate 13. The wind wheel 3 is located in the inner cavity of the cylindrical honeycomb structure, and the air entering from the air inlet 11 first enters the inner cavity 5 of the wind wheel 3 and then passes through the honeycomb pores of the honeycomb body 2 and flows out from the air outlet 12, and the sprayer 4 is arranged on the air flow channel in front of the air inlet surface of the honeycomb body 2, and the sprayer 4 is connected with the water inlet 41.

[0045] In this example, the shell 1 is a quadrilateral when viewed from above, and air outlets 12 are arranged on the sides of the shell 1 in two directions.

[0046] In this example: the honeycomb body 2 is made of sintered microporous ceramic material, has a developed pore structure and a huge specific surface area, and has good water absorption.

[0047] In this example, the air inlet 11 is connected to the inner cavity 5 of the fan wheel 3.

[0048] In this example: the sprayer 4 is disposed at the air inlet 11 on the air flow channel in front of the air inlet surface of the honeycomb body 2 .

[0049] In this example: the wind wheel 3 is a multi-blade centrifugal impeller, whose shaft is driven to rotate by a motor 31. The wind wheel 3 and the motor 31 are connected by a transmission belt. A small gap 7 is left between the wind wheel 3 and the housing 1 and the bottom plate 13.

[0050] In this example: the sprayer 4 is connected to a water inlet 41 , and the water supply device connected to the water inlet 41 is a tap water pipe and is provided with a solenoid valve 42 .

[0051] In this example: a temperature and humidity sensor 71 is provided near the air outlet 11 .

[0052] In this example: the bottom plate 13 is provided with a drainage port 44 .

[0053] In this embodiment, the sprayer is arranged at the air inlet, so that the space occupied by the sprayer in the annular air duct 6 of embodiment 1 can be reduced, so that the diameter of the wind wheel can be increased to provide a larger air volume, and the air outlet is only arranged on two sides of the shell, so that the wind force is more concentrated and the wind force of the air outlet can be further improved. The cold air from the two air outlets can be introduced into the room respectively through pipes. The sprayer is arranged at the air inlet and uses tap water for water supply. The structure is simpler and maintenance is more convenient, which is suitable for large air volume model design installed outdoors.
