HVAC engineering refers to the engineering that utilizes the characteristics of indoor and outdoor air to maintain a suitable indoor environment through heating, ventilation, air conditioning, ventilation and other technologies. HVAC engineering belongs to building equipment engineering.

[0003] A Chinese patent application CN211384372U discloses a construction site dust removal device for HVAC engineering. The key points of its technical solution are: water enters the interior of the frame through the water exchange pipe, and air enters the frame through the air intake pipe. The dust mixed in the air will melt in the water to achieve dust removal operation on the air. At the same time, a first activated carbon filter layer is provided to purify the air, and the air quality sensor is used for detection. If the cleanliness level does not meet the requirements, the air will be purified and discharged through the second activated carbon filter layer to achieve secondary filtration.
