What is the air supply distance of a grain storage air conditioner related to?

1. Air supply method and design of the air conditioner

Air supply method: For example, horizontal or vertical air supply. Different air supply methods affect the diffusion and propagation path of the airflow, thereby influencing the air supply distance.

Deflector nozzle design: Grain storage-specific air conditioners often use a deflector nozzle design, which can more effectively deliver cold air over longer distances. According to reference articles, the standard width of a grain storage facility is 24 meters. Grain storage-specific air conditioners with a deflector nozzle design can achieve an effective air supply distance of up to 16 meters, with a maximum air supply distance of approximately 24 meters.

2. Power and performance of the air conditioner

Cooling capacity and sensible heat ratio: Grain storage-specific air conditioners typically have a large cooling capacity and a high sensible heat ratio, meaning they can more effectively reduce air temperature while maintaining low humidity, thereby increasing the air supply distance.

Circulating air volume: The larger the circulating air volume, the more air passes through the air conditioner per unit of time, theoretically increasing the air supply distance. For example, a certain model of grain storage-specific air conditioner has a circulating air volume of 3200 m³/h, which helps achieve a longer air supply distance.

3. Indoor environment and layout of the grain storage

Grain storage size: The size of the grain storage directly affects the air supply distance. In larger grain storage facilities, a greater air supply volume and longer air supply distance are required to ensure uniform temperature and humidity throughout the entire space.

Indoor layout: The indoor layout and obstacles (such as grain piles, equipment, etc.) can affect the propagation path and speed of the airflow, thereby influencing the air supply distance. A reasonable layout and reduced obstacles can improve air supply efficiency.

4. Distance between the air supply outlet and the ventilation outlet

Location of air supply outlets: The position and number of air supply outlets affect the distribution of airflow and the air supply distance. Proper placement of air supply outlets ensures that cold air evenly covers the entire grain storage.

Distance between air supply outlets and ventilation outlets: The farther the air supply outlet is from the ventilation outlet, the greater the required air velocity to ensure that cold air can effectively reach and cover the entire grain storage. However, excessive distance may also lead to a decrease in air velocity and reduced air supply effectiveness.
