Building energy-saving thermal series
THFDI type wind tunnel
For calibration and verification. This wind tunnel is suitable for the qualification test of wind measuring instruments and wind sensors and other wind tunnel simulation tests.
Its characteristics are: small size, wide wind speed measurement range, uniform and stable flow field, and low noise.

Detailed Introduction
Carry out calibration and verification standards:
a. Verification Regulations for Lightweight Magnetic Induction Wind Direction Anemometer JJG515;
b. Verification Regulations for Electric Wind Direction Anemometer JJG613;
c. Verification Regulations for Thermal Ball Anemometer JJG (Construction) 0001;
d. DEM6 portable three-cup wind direction and anemometer verification regulations JJG431;
The air is inhaled from the air inlet, rectified by 8 and 9, and accelerated to the required wind speed by the contraction section 14 for the test section 3, and then decelerated and discharged through the diffusion section 2. The locking nut of the pit tube and the observation windows 4 and 7 are installed on the test section, and the meter bracket 13 can be replaced to prepare for fixing different forms of meters.

Structure and principle:
The main material of this wind tunnel is glass fiber reinforced plastic, and it adopts the form of closed and open circuit with circular section. In addition to the test section 5, the stable section 6 also has a window for low wind speed tests.The air is inhaled from the air inlet, rectified by 8 and 9, and accelerated to the required wind speed by the contraction section 14 for the test section 3, and then decelerated and discharged through the diffusion section 2. The locking nut of the pit tube and the observation windows 4 and 7 are installed on the test section, and the meter bracket 13 can be replaced to prepare for fixing different forms of meters.
