What Is Variable Air Volume?
The Variable Air Volume System (VAV system) was born in the United States in the 1960s. It is an all-air air-conditioning system that automatically adjusts the air volume of the air-conditioning system based on changes in indoor loads or changes in indoor required parameters, so that the indoor parameters meet the requirements. .

- The Variable Air Volume System (VAV system) was born in the United States in the 1960s. It is an all-air air-conditioning system that automatically adjusts the air volume of the air-conditioning system based on changes in indoor loads or changes in indoor required parameters, so that the indoor parameters meet the requirements. .
- Since the air-conditioning system operates most of the time under partial load, the reduction in air volume has brought about a reduction in fan energy consumption. VAV system pursues to meet the requirements of indoor air environment with less energy consumption. After the advent of the VAV system, it was not quickly promoted. At that time, the United States still dominated the Constant Air Volume (CAV) system plus end reheating and dual air duct systems. The oil crisis that broke out in the West in the 1970s caused VAV systems to be widely used in the United States, and continued to develop in the next 20 years. It has become the mainstream of American air-conditioning systems and is also used in other countries.
- The application of variable air volume in the laboratory field has only begun in recent years. It is mainly used for ventilation speed control of mulberry noodles. With the attention of laboratory staff to the safety of the working environment, the use of variable air volume has become wider !! Source: Shenzhen Oracle Airflow Control System Co., Ltd.!
