Variable air volume distribution fan is applied to low-noise air conditioning systems, which aims to miniaturize, modularize, and improve the design of marine air distribution fans to achieve low noise. At the same time, the adjustment performance and reliability of the air distribution fan are improved, and the noise inside the air conditioning cabin is reduced to meet the comfort and low-noise control requirements of ship air conditioning systems.

The variable air volume distribution fan receives temperature setting instructions from the cabin temperature controller and automatically adjusts the air volume sent into the cabin based on the indoor temperature, achieving independent temperature control for each cabin; Equipped with electric heating auxiliary heating function, it can automatically shut down and turn on the electric heater in the air distributor according to the cabin temperature to meet the cabin temperature requirements while ensuring the minimum air supply volume in the cabin; It also has the function of measuring air volume, which can provide feedback on the required air volume and other parameters of the cabin to the variable air volume air conditioner.
