Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and humidification, and particularly relates to a humidifying device for heating ventilation and air conditioning engineering. Background Art

[0002] HVAC is an air conditioner with heating, ventilation and air conditioning functions. Generally, in places where centralized heating is required, such as factory dormitories, hospitals or factory buildings, central air conditioners are used as HVAC to ensure heating or cooling in the room. When HVAC is in use, a humidifying device is often needed to moisten the air to prevent the air discharged from the air conditioner from being too dry. At present, most of the humidifying devices used are wet film humidifiers. For example, a humidifying device for heating ventilation and air conditioning engineering disclosed in the patent application No. CN202322454149.4 includes a humidifying box with openings on both the left and right sides. The bottom of the humidifying box is fixedly installed with several support legs. A filter screen is fixedly installed on the left side of the humidifying box. Two vertical plates are respectively fixedly installed on both sides of the humidifying box. A wet curtain is arranged between the two vertical plates close to each other. Second through slots are respectively opened on the vertical plates. Third through slots are opened at the bottom sides of the two inner vertical plates. A rotating shaft is rotatably installed between the two inner vertical plates. One end of the rotating shaft is fixedly installed with a fan impeller. Short tubes are fixedly installed on the outer periphery of the fan impeller. Several water ladles are respectively fixedly installed on both sides of the short tubes. A water pool is arranged between the two inner vertical plates.

[0003] When the above structure humidifies the air, it can drive the fan impeller to rotate, so that the short tube drives the water ladles to rotate, thereby completing the water circulation and reducing additional mechanisms to realize the water circulation.

[0004] However, the above technical solutions still have some technical problems. For example, the wet curtain is actually in direct contact with the water pool all the time. When the ventilation system is not working, the wet curtain that always maintains humidity is prone to becoming a breeding ground for bacteria. At the same time, this will cause the wet curtain to always have humidity, but the wet curtain is in a state of being dry at the top and wet at the bottom. Excessive humidity will hinder the airflow from passing through the wet curtain, while insufficient humidity will lead to insufficient water vapor carried by the airflow, resulting in poor humidifying effect. Moreover, the rotation of the entire short tube is supported only by the rotating shaft, and the overall structural stability is not good. Especially after driving the short tube by a motor, the whole will shake during operation, resulting in the vibration of the overall structure and thus generating serious noise. Summary of the Utility Model

[0005] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides a humidifying device for heating ventilation and air conditioning engineering, which can make the wet curtain have uniform humidity and improve the overall stability at the same time.

[0030] Refer to Figure 1 、 Figure 2 and Figure 4As shown in the figure, a humidifying device for heating, ventilation and air conditioning engineering according to an embodiment of the present utility model includes a humidifying box body 100 and a humidifying mechanism. The humidifying box body 100 is sequentially provided with an air inlet area 110, a humidifying area 120 and a air supply area 130 along the air flow direction. Cushion blocks 140 are connected to the joints between the air inlet area 110 and the humidifying area 120 and between the air supply area 130 and the humidifying area 120. A wet curtain 300 is connected to the cushion blocks 140, and fixing plates 400 are respectively connected to both sides of the wet curtain 300; a lower fixing seat 150 is connected to the inner wall of the humidifying area 120 between the two cushion blocks 140, and an upper fixing seat 160 is connected to the inner wall of the humidifying area 120 opposite to the lower fixing seat 150. The humidifying mechanism includes a motor 210 and a fan connected to the motor 210.
