Description

Technical Field

[0001] This utility model relates to the field of fresh air handling unit technology, and in particular to a wet curtain pre-cooling direct expansion fresh air handling unit. Background Technology

[0002] A direct expansion air handling unit is a high-efficiency fresh air treatment device that integrates a refrigerant direct evaporation cooling / heating system and a fan. It can directly draw in and process air from the outside and then send it indoors.

[0003] Its pre-cooling components mainly consist of a wet curtain, nozzles, and baffles. During use, when hot air flows through the wet curtain, the water evaporates and absorbs heat from the air, thus pre-cooling the air. Subsequently, the air passes through the baffles, which can block the water vapor carried in the air. However, the blocked water is prone to accumulate inside the unit's casing. Since the water level inside the casing cannot be directly observed, it is difficult to drain the water in a timely manner. Therefore, this solution proposes a wet curtain pre-cooling direct expansion fresh air unit to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wet curtain pre-cooling direct expansion fresh air handling unit to solve the problems mentioned in the background art.

[0023] 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.

[0024] This utility model provides, for example Figure 1-4 Shown:

[0025] Example 1: A wet curtain pre-cooling direct expansion fresh air handling unit, comprising:

[0026] Fresh air unit 1;

[0027] The precooling component 2 includes a frame 205 disposed on one side of the fresh air unit 1, a precooling component disposed inside the frame 205, and a water outlet pipe 206 disposed at the bottom of the frame 205.

[0028] The lifting assembly 3 includes a float 304 disposed inside the frame 205, a push rod 301 disposed on the top of the float 304, and a limiting member disposed inside the frame 205 to limit the movement direction of the push rod 301.

[0029] Display component 4 is located on top of push rod 301 and is used to limit water level.

[0030] It should be noted that the direct expansion fresh air unit 1 is a high-efficiency fresh air handling device that integrates a refrigerant direct evaporation cooling / heating system and a fan. It can directly extract and process air and then deliver it to the required location. The float 304 is made of high-density polyethylene, which has a lower density than water, allowing it to float in water. The float 304 drives the push rod 301 to move. A ball valve is installed in the middle of the outlet pipe 206. During use, the ball valve controls the outlet pipe 206 to control the drainage of water inside the frame 205. When water begins to accumulate inside the frame 205, the water will drive the float 304 upward, which in turn drives the push rod 301 to move. The movement of the push rod 301 and the float 304 is displayed by the display component 4, allowing users to observe the water level inside the frame 205 for timely drainage.

[0031] Specifically, the precooling component includes a wet curtain 203 installed inside the frame 205, a water spray section is provided on the top of the wet curtain 203, a baffle plate 204 is provided inside the frame 205, and the water spray section includes a water supply pipe 201 that is inserted and connected to the front of the frame 205, and a nozzle 202 is provided at the bottom of the water supply pipe 201.

[0032] It should be noted that the water supply pipe 201 is fixedly connected to the front of the frame 205 by welding. One end of the water supply pipe 201 is provided with a connecting flange, which is used to connect to the water supply pipe. This design allows water to enter the interior of the water supply pipe 201, and then the water supply pipe 201 is used to enter the interior of the nozzle 202, which sprays the water onto the wet curtain 203. During use, when hot air flows through the wet curtain 203, the water evaporates due to the heat and absorbs heat from the air, thus achieving air pre-cooling.

[0033] Specifically, the limiting components include a top frame 302 fitted onto the bottom of the push rod 301, and multiple uprights 303 are symmetrically fixedly connected to the bottom center of the top frame 302. The uprights 303 are fixedly connected to the inner wall of the bottom end of the frame 205.

[0034] It should be noted that at least two uprights 303 are provided. Multiple uprights 303 are used to fix the position of the top frame 302. A hole is provided in the middle of the top frame 302 for the uprights 303 to pass through, and the outer wall of the upright 303 fits against the inner wall of the hole in the middle of the top frame 302. The top frame 302 restricts the movement direction of the uprights 303.

[0035] Specifically, a sealing ring 5 is fitted on the top of the push rod 301, and the sealing ring 5 is inserted and connected to the top of the frame 205.

[0036] It should be noted that the sealing ring 5 is made of rubber. During use, it seals the connection between the frame 205 and the push rod 301 to prevent gas from leaking out from the connection between the frame 205 and the push rod 301.

[0037] Example 2: Display component 4 is applied to the direct expansion fresh air unit in Example 1;

[0038] Specifically, the display component 4 includes a fixing block 402 fixedly connected to the top of the frame 205. A through hole 401 is provided in the middle of the fixing block 402. A push rod 301 is inserted into the through hole 401. A top block 403 is fixedly connected to the top of the push rod 301. A connecting block 404 is fixedly connected to the top of the fixing block 402. A baffle 405 is fixedly connected to the top of the connecting block 404.

[0039] It should be noted that the through hole 401 in the middle of the fixed block 402 is adapted to the push rod 301, allowing the push rod 301 to pass through the fixed block 402 and connect with the top block 403. The diameter of the top block 403 is larger than the diameter of the through hole 401, preventing the top block 403 from passing through the fixed block 402. The top block 403, which limits the movement distance, restricts the movement distance of the push rod 301 and the float 304. The baffle 405 is used to limit the movement distance of the top block 403. In use, when the top block 403 is in contact with the baffle 405, it indicates that the water level has reached the preset height. At this time, the ball valve on the outlet pipe 206 needs to be opened to drain the water.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
