Variable Air Volume (VAV) air conditioning system
Variable Air Volume (VAV) air conditioning system is a type of centralized all air air conditioning system that can automatically adjust the supply air volume of the corresponding VAV terminal devices in the air conditioning system according to changes in load, temperature, or air quality (CO2) in the cabin, so that the indoor temperature, air quality, etc. meet the set requirements. When the air supply volume in the cabin decreases with the decrease of air conditioning load, the fan of the air conditioning system adjusts its speed through a variable frequency device to reduce the air supply volume of the air conditioning system, which has the advantages of energy saving, low noise, intelligent control, etc. It is widely used in various luxury passenger ships, scientific research ships, government ships, marine platforms and other fields.
