Description

a humidity control device

Technical field

The present application relates to the technical field of humidity control devices, and in particular to a humidity control device with high reliability.

Background technique

The data center is the core area of the control system in various fields, and it is extremely important to ensure its stable operation. The stable operation of the data center depends to a large extent on the temperature and humidity of the computer room environment in which it is located. Therefore, the data center is very important to the temperature and humidity of the computer room. Humidity has strict requirements, especially small fluctuations in temperature and humidity, high reliability requirements for environmental temperature and humidity control equipment, and high frequency of maintenance. The temperature of the computer room can be controlled by air conditioning, while the humidity control generally uses a constant humidity machine.

When the existing constant humidity machine is humidifying, the wet film fully absorbs water to form a water film, and the passing air is converted into humid air through the force of the air supply. If the air supply speed is too high or the air flow organization is uneven and the local wind speed is too high, the wet film will produce flying water. Since the water used for wet film humidification is circulating water, the calcium and magnesium ion content increases over time. Flying water will adhere to the heat exchanger installed downstream near the wet film and cause surface scaling, causing the performance of the heat exchanger to decrease and wind resistance to increase. As a result, the performance of the constant humidity machine is greatly reduced. Therefore, the existing constant humidity machine has problems such as water flying from the wet film and the heat exchanger behind the wet film being easily dirty. Maintenance is often required, otherwise the reliability of the equipment will be reduced.

In the humidification mode, the heat exchanger 16 does not work, and the external air enters the casing 12 through the air inlet. The fan 20 operates so that the area where the wet film 14 is located is in a negative pressure state, and the air is attracted to flow to the wet film 14 and becomes higher in humidity. In the moist air, the moisture that has not completely evaporated on the wet film 14 slides into the first water receiving pan 22, and then is discharged into the main water tank 38 through the first water outlet hole 50, so as to avoid water accumulation in the first water receiving pan 22 and causing insufficient drainage. Smoothly, the humid air is attracted by the fan 20 to flow to the air outlet and discharged to the external space to achieve the humidification effect.

During the humidification process, if the wind speed of the fan 20 is too high or the local wind speed is too high due to uneven airflow organization, flying water will appear on the wet film 14, and the flying water will be intercepted by the water blocking module 18, leaving the flying water in the water blocking module. 18, the moist air passes smoothly, preventing the heat exchanger 16 from being polluted by the circulating water on the wet membrane 14. When the water blocking module 18 becomes dirty and blocked after working for a long time, the unit can be replaced without stopping, which greatly improves the reliability of equipment operation.

In the dehumidification mode, the wet film 14 and its spray device do not work. The external air enters the casing 12 through the air inlet and then flows to the evaporator of the heat exchanger 16. The refrigerant medium in the evaporator encounters hot air and vaporizes. Absorb the heat of the air to dehumidify it. At this time, part of the wet steam will condense into water on the hydrophilic fins. After the water gathers, it will fall into the second water receiving tray 24 under the action of gravity. The second water receiving tray 24 The water inside is discharged from the second water outlet hole 52 to the main water tank 38, and the dehumidified air flows from the air outlet to the external space to achieve the dehumidification effect.

As shown in Figure 4, in some embodiments, the heat exchanger 16 can also be placed close to the air inlet. The arrow in the figure indicates the direction of the air inlet. The wet film 14 is placed on the side of the heat exchanger 16 away from the air inlet. This design can Without the water blocking module 18 , the air first passes through the heat exchanger 16 and then through the wet film 14 , which can effectively solve the problem that the flying water generated by the wet film 14 reaches the heat exchanger 16 and causes the heat exchanger 16 to be corroded and easily clogged.
