During the construction quality acceptance process of ventilation and air conditioning engineering, the quality of air ducts must be inspected separately according to different material processing techniques, system categories, etc., which should include the material, specifications, strength, tightness, visual quality, and other contents of the air ducts; After the installation of the air duct system, a tightness inspection should be conducted, and only after passing the inspection can it be delivered to the next process; The insulation engineering construction of related equipment and components should be carried out after the tightness inspection of the air duct system is qualified.

Requirements for air duct tightness inspection in engineering acceptance

--Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering GB 50243-2016

Case 1: Dongguan People's Hospital Project

The TID project of Dongguan People's Hospital is a cooperative construction between the hospital and the Municipal Transportation Investment Group, aiming to create an integrated "transportation+medical" TID project in the city. It is a key provincial and municipal project and a pilot project for the reform of Dongguan's innovative investment and financing system and mechanism. The project is located in the Honglou Campus of Dongguan People's Hospital, adjacent to the People's Hospital Station of Dongguan Metro Line 1. The overall project includes the construction of one science and education comprehensive building, one emergency center, and a double layered underground space, including the People's Hospital bus terminal, civil air defense engineering, and seamless connection engineering between subway and bus.

Key points for purchasingUltra wide measurement range, more precise testing requirements.

·Both positive and negative pressure pipelines can be measured

By changing the connection of the corrugated pipe, the sealing performance of the pipeline under positive and negative pressure can be tested.

·Comprehensive built-in regulations that can be directly judged

EN1507:2006、EN12237:2002Eurovent 2/2、SMACNA StandardAABC Standard、DW/143GB50243—2016

According to the corresponding regulations, the sealing performance of the tested pipeline can be directly determined to be qualified.

·Increased measurement range

The range of measurable leakage has increased, and the measurable area has increased threefold.

·Accuracy performance guarantee

Wide air flow measurement range, two types of measuring nozzles ensure measurement accuracy, and the nozzle is easy to switch without the need to plug or unplug air pipes.

·Touch screen display and built-in storage

5-inch LCD touch screen, easy to operate, real-time display of leakage, test pressure, temperature, and atmospheric pressure, built-in 1000 sets of data storage for easy browsing and deletion, and can be connected to an external printer for real-time printing, making it easy to organize and record.

·Compact in size, convenient for transportation

Lightweight and smaller in size, it can be carried in the trunk of SUV family sedans for easy transportation.

Case 2: Guangdong CITIC Financial Center Project

The project is planned as a large-scale super high-rise urban complex that integrates office, commercial, hotel, and cultural functions. The core highlight of its design is undoubtedly the "twin tower" shape composed of two iconic towers. The main tower, reaching a height of 300 meters and consisting of 62 floors, is positioned as a super Grade A office building. And the other tower is 170 meters high, standing side by side with the main tower, together forming the image of "setting sail, the sail of Super Bay".
