On-site testing equipment for kitchen and bathroom exhaust duct system performance
This equipment automatically controls pressure, air flow, accurate data, beautiful appearance, light weight and easy to carry, etc., and is suitable for on-site testing.
Detailed Introduction
■On-site testing equipment for kitchen and bathroom exhaust duct system performance. This equipment is developed by Beijing Zhongke Tianhao Technology Co., Ltd. in accordance with the current standard GBJ33T1289-2022, "Technical Regulations for the Application of Residential Kitchen Mixed Gas Exhaust Duct Systems".
The on-site testing equipment for kitchen and bathroom exhaust ducts can be used for the smoke prevention and backflow prevention method inspection (equipped with a smoke generator), tightness inspection for smoke prevention and backflow prevention (equipped with a roof exhaust port sealing device), and system imbalance rate inspection specified in Appendix A of DBJ33/T1289-2022.

■This equipment automatically controls pressure and air flow, ensures accurate data, boasts an aesthetically pleasing appearance, is lightweight and easy to carry, and is suitable for on-site testing.
Main performance parameters：
1. Equipment power: AC 220V, power 500W.
2. Fan outlet diameter: DN150mm.
3. Piezometer tube length: L=1100mm.
4. Motor power: 200W (energy-saving motor).
5. The weight of a single set of equipment is approximately 5kg.
6. Loading method for the entire machine: closed-loop feedback control.
7. Wind pressure: greater than 400 pa.
8. Exhaust air volume: greater than 780 cubic meters per hour.
9. Standard configuration quantity: 11 sets. Capable of testing 11 floors (non-standard floor numbers can be customized).
10. Control mode: Multi-machine wireless stepless speed regulation fan.
11. Collection method: Transmission via wireless LoRa module, ad hoc network, fast speed, and stable data.
12. Control host: tablet computer, on-site inspection, convenient and fast.
Equipment features：
1. The detection of exhaust ducts requires the measurement of wind speed and volume based on controlled wind pressure, in order to calculate the sealing performance of the exhaust ducts.
2. The detection of exhaust ducts needs to be conducted from multiple floors, requiring personnel to make multiple trips to each floor for setting up and measurement, which is both time-consuming and laborious. This system can achieve the function of controlling multiple sets of fans with one handheld computer, improving measurement efficiency.
3. This system allows for independent adjustment of the speed of each fan, and the wind pressure, wind speed, and air volume of each fan are displayed both locally and remotely.
4. This system is easy to operate, requiring only power supply on site, with no additional wiring necessary.
5. It features portability, ease of carrying, and an aesthetically pleasing and durable design suitable for on-site use.
6. Adopt wireless remote control to adjust fan flow and collect flow and pressure data in real time.
7. The air volume meter adopts a wireless transmission module to send data in real-time to a remote control box, laptop, or tablet for control。
