Product features:

1. variable air volume terminal device can automatically change the air supply volume according to the change of cabin load and personal comfort requirements, so the air conditioning comfort is good, can meet the personalized needs of users;

2. Air volume can be adjusted preferentially according to load changes. Except the peak period of heat load, the air conditioning and ventilation system operates under low air volume, which can effectively reduce the noise of the air conditioning system;

3. The air volume can be adjusted timely according to the load changes to effectively reduce the energy consumption of the blower, and achieve the dual purpose of comfort and energy saving;

4. The cooling or heating amount can be adjusted automatically with the change of the actual load by adjusting the air supply volume and air supply temperature, with a high degree of automation control;

5. The cost of vAV air conditioning system equipment will be increased due to the increase of monitoring links such as static pressure of the system, indoor temperature and air volume, and outdoor fresh air volume.
