Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a humidification system and a precision air conditioner. Background Art

[0002] The temperature and humidity control of precision air conditioners is crucial to ensure the normal operation of the equipment. Precision air conditioners monitor the air temperature and humidity in real time. When the humidity is too high, the precision air conditioner will start the dehumidification function. Usually, the air temperature is lowered by cooling coils, so that the water vapor in the air condenses into water droplets and is discharged, thereby reducing the humidity; if the humidity is too low, the computer room air conditioner will perform humidification. Common humidification methods include steam humidification and ultrasonic humidification. Most existing precision air conditioners use steam humidification.

[0003] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems:

[0004] In existing humidifiers, the overflow pipe and the drain pipe of the dehumidification coil are combined and discharged to the outside. When the overflow pipe in the humidifier does not need to be drained, the humidified steam will enter the room from the overflow pipe through the drain pipe of the dehumidification coil, resulting in the inability to accurately control the indoor humidification amount. Summary of the invention

[0005] In view of this, the present invention provides a humidification system, which solves the problem that the humidification steam enters the room through the overflow pipe and the drainage pipeline, resulting in the inability to accurately control the indoor humidification amount through the setting of a U-shaped overflow pipe.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The humidification system provided by the embodiment of the present invention is as follows: Figure 1-Figure 3 As shown, including:

[0042] The water tank assembly comprises a water tank 10, wherein a low water level line 11 and a high water level line 12 are preset in the water tank 10;

[0043] A humidifying component, comprising a humidifier 20 and a humidifying steam spray pipe 21, wherein the humidifier 20 is connected to the humidifying steam spray pipe 21, and the humidifier 20 is located in the water tank 10;

[0044] The overflow assembly includes an overflow pipe 40, which is a U-shaped structure. The overflow pipe 40 has an overflow straight pipe portion 41, a curved portion 42 and a drainage straight pipe portion 43 which are connected in sequence; the overflow port of the overflow straight pipe portion 41 is located below the low water level line 11, and the curved portion 42 is located above the high water level line 12;

[0045] The main drain pipe 50 , the drain outlet of the drain straight pipe portion 43 , and the drain outlet of the water receiving tray 31 are all connected to the main drain pipe 50 .

[0046] In the above technical solution, when the water level in the water tank 10 exceeds the high water level line 12, under the action of pressure, the overflow port of the overflow straight pipe part 41 will produce a drainage phenomenon, and the water flows into the overflow port of the overflow straight pipe part 41, passes through the curved part 42 and the drainage straight pipe part 43 in turn, and is discharged into the main drainage pipe 50 from the drainage port of the drainage straight pipe part 43; in the prior art, the drainage port of the existing overflow pipe and the drainage port of the water receiving pan 31 are both connected to the main drainage pipe 50, resulting in the existing overflow pipe and the water receiving pan 31 being connected, which will cause the existing overflow pipe to not overflow. The steam generated in the box will flow from the existing overflow pipe to the water receiving pan 31 and then enter the room, making it impossible to accurately control the humidification amount. In the present technical solution, the overflow pipe 40 is set to a U-shaped structure, and the overflow port of the overflow straight pipe portion 41 is located below the low water level line 11, thereby preventing steam from flowing from the overflow port of the overflow straight pipe portion 41 to the water receiving pan 31, and the curved portion is located above the high water level line 12. When the water level in the water tank 10 exceeds the high water level line 12, the overflow port of the overflow straight pipe portion 41 will produce drainage under the action of pressure, thereby realizing the drainage function of the overflow pipe 40.

[0047] Compared with the prior art solutions, the present technical solution, through the setting of the U-shaped overflow pipe 40, can achieve the overflow and drainage function while preventing the steam in the water tank 10 from entering the room through the overflow pipe 40 and the water receiving tray 31, so that the indoor humidification amount can be accurately controlled.

[0048] In one technical solution, the humidification system is applied to precision air conditioning and has a dehumidification component. The dehumidification component includes a dehumidification coil 30 and the above-mentioned water receiving pan 31. The water receiving pan 31 is used to receive condensed water dripping from the bottom of the dehumidification coil 30.

[0049] Optimize the above technical solutions, such as Figure 2-Figure 3 As shown, the overflow assembly further includes: a bypass pipe 44;

[0050] A first end of the bypass pipe 44 is communicated with the bent portion 42 , and a second end of the bypass pipe 44 is communicated with the water receiving pan 31 .

[0051] In the above technical solution, a bypass pipe 44 is connected to the curved portion 42 of the overflow pipe 40 so that the top position of the overflow pipe 40 and the internal air pressure of the water tank 1 are kept balanced, thereby eliminating the problem of siphon phenomenon in the overflow pipe 4 after the water level is too high (if the bypass pipe 44 is not provided, a siphon phenomenon will occur during drainage, and the overflow pipe 40 will continue to drain water to the overflow port, resulting in excessive drainage, which will lead to more water added to the humidifier); of course, it should also be noted that the bypass pipe 44 is led to the water receiving tray 31 under the front of the dehumidification coil to prevent the overflow pipe 40 from leaking outside the equipment during drainage).

[0052] Further optimization of the above technical solution, such as Figure 2As shown, the curved portion 42 is connected to the first end of the bypass pipe 44 at one side near the top thereof, and the water receiving tray 31 is connected to the second end of the bypass pipe 44 at one side near the overflow pipe 40;

[0053] The connection point between the side of the water receiving pan 31 close to the overflow pipe 40 and the second end of the bypass pipe 44 is a first connection point.

[0054] In the above technical solution, the first end of the bypass pipe 44 is connected to the top side of the curved portion 42, which can better balance the top position of the overflow port and the air pressure inside the water tank 1, thereby eliminating the siphon problem of the overflow pipe 4 after the water level is too high.

[0055] The above technical solution is further optimized, and also includes a dehumidification coil 30. The projection of the dehumidification coil 30 in the vertical direction is staggered with the first connecting point, and the overall projection of the dehumidification coil 30 in the vertical direction is staggered with the first connecting point, so that the pressure in the bend 42 is basically consistent with the atmospheric pressure, and the water level in the water tank 10 can be adjusted according to the air pressure in the bend 42.

[0056] In this technical solution, if Figure 3 As shown, it also includes a dehumidification coil 30, a curved portion 42 near the top thereof is connected to the first end of a bypass pipe 44, and a water receiving pan 31 away from the overflow pipe 40 is connected to the second end of the bypass pipe 44;

[0057] The connection point of the water receiving pan 31 away from the overflow pipe 40 and connected to the second end of the bypass pipe 44 is the second connection point;

[0058] The projection of the dehumidification coil 30 in the vertical direction at least partially overlaps with the second connection point; it should be noted that Figure 1-Figure 3 The portion of the dehumidification coil 30 protruding to the right (i.e., the portion overlapping with the second connection point) is shown in FIG. Figure 1-Figure 3 is hidden in Figure 1-Figure 3 not displayed).

[0059] In the above technical solution, the first end of the bypass pipe 44 is connected to the top side of the bend 42, which can make the top position of the overflow port and the internal air pressure of the water tank 1 maintain balance, and can eliminate the problem of siphon phenomenon after the overflow pipe 4 is over-high water level. As a preferred embodiment, the dehumidification coil 30 is fin-type, with copper tubes and aluminum foil in the middle, forming a small gap. The projection of the dehumidification coil 30 in the vertical direction at least partially overlaps with the second connection. In the process of airflow flowing from the small gap to the second connection, the airflow is blocked, so that the air pressure in the bend 42 is less than the atmospheric pressure. The water level in the water tank 10 can be adjusted according to the air pressure in the bend 42; it should be noted that when the second end of the bypass pipe 44 is connected to the first connection, the air pressure in the bend 42 is greater than the air pressure in the bend 42 when the second end of the bypass pipe 44 is connected to the second connection. Of course, the second end of the bypass pipe 44 can be connected to the first connection or the second connection according to actual needs.

[0060] In this technical solution, if Figure 1-Figure 3 As shown, the drain outlet of the water tank 10 is connected to the main drain pipe 50. The drain outlet of the water tank 10 can drain the water in the water tank 1 during maintenance. In one embodiment, it also includes a manifold 60. The water tank 10 is provided with a water tank drain pipe 13. The water receiving pan 31 is connected to a water receiving pan drain pipe 32. The drain pipe 13, the drain outlet of the drain straight pipe portion 43, and the water receiving pan drain pipe 32 are all connected to the main drain pipe 50 through the manifold 60. Further, the manifold 60 is provided with a drain solenoid valve 14 (such as Figure 2 As shown), it is used to control the opening and closing of the drain pipe 13.

[0061] In the present technical solution, the water receiving tray 31 is located above the humidifier 20. This arrangement prevents the water in the overflow pipe 40 from flowing into the water receiving tray 31 through the bend 42 and the bypass pipe 44, which is beneficial to the precise control of the humidification system. Of course, for the convenience of display, Figure 1-Figure 3 In the embodiment, the water tank assembly, the humidification assembly, the dehumidification assembly and the overflow assembly are arranged side by side.

[0062] In this technical solution, if Figure 2 As shown, the humidification assembly further includes: a cylinder 22 located in the water tank 10;

[0063] The humidifier 20 is located in the cylinder 22, and a heating space 23 is formed between the humidifier 20 and the inner wall of the cylinder 22. The heating space 23 is communicated with the water storage space 15 in the water tank 10, so that the humidifier 20 heats the water source entering the heating space 23 from the water storage space 15 to form steam.

[0064] In the above technical solution, when the humidifier 20 is used for heating, the water in the cylinder 22 can reach the temperature of steam generation first, which can shorten the entire humidification process compared to heating the entire water tank 10; preferably, the humidifier is an electric heating humidifier, and the cylinder 22 is arranged so that when the water source is replenished, the water source that flows into the water tank 10 (that is, the water storage space 15) later has little effect on the temperature of the heating space 23 in the cylinder 22, and will not interrupt or shorten the humidification speed.

[0065] Optimize the above technical solutions, such as Figure 2 and Figure 3 As shown, the top end of the cylinder 22 is fixed to the top wall of the water tank 10 , and the gap between the bottom end of the cylinder 22 and the bottom wall of the water tank 10 forms a communication channel, which connects the heating space 23 with the water storage space 15 .

[0066] In the above technical solution, the water source enters the heating space 23 from the water storage space 15 through the connecting channel; the preferred vertical length of the connecting channel is about 3 mm (that is, the distance between the bottom end of the cylinder 22 and the bottom wall of the water tank 10 is 3 mm).

[0067] In one technical solution, a water level switch 16 for controlling the water level of the water tank 10 is provided in the water tank 10 .

[0068] In the present technical solution, a water level switch 16 is used to control the water level of the water tank 10 between high and low water levels. When the water level of the water tank 10 is lower than the low water level line 11, the water level switch 16 controls the water inlet pipe 17 to add water. When the water level of the water tank 10 is higher than the high water level line 12, the water level switch 16 controls the water inlet pipe 17 to stop adding water.

[0069] In this technical solution, if Figure 2 As shown, a manual ball valve 18 and / or a water inlet solenoid valve 19 is provided on the water inlet pipe 17 of the water tank 10. Such a configuration can control the water inlet pipe 17 manually or automatically to allow water to flow into or stop the water inlet to the water tank 10.

[0070] In one embodiment, the indoor air is converted into dry air (i.e., dehumidified air) by the dehumidification coil 30. Figure 3 The first arrow A in the figure points to the direction of the indoor incoming air being converted into dry air.

[0071] In another embodiment, the unhumidified air is converted into humidified air through the humidified steam nozzle 21. Figure 3 The first arrow B in the figure points to the flow direction of the non-humidified air being converted into the humidified air; it should also be noted that the first arrow C points to the flow direction of the humidified steam.

[0072] The present invention also provides a precision air conditioner, including: the humidification system as described above. Since the present solution adopts the humidification system as described above, it also has corresponding beneficial effects, which can be specifically referred to the above description and will not be repeated here.
