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 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 warehouse is 24 meters, and 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 around 24 meters.

2. Power and performance of the air conditioner

Cooling capacity and sensible heat ratio: Grain storage-specific air conditioners typically have high 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.

Air circulation volume: The greater the air circulation 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 an air circulation 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, greater air supply volume and longer air supply distances are required to ensure uniform temperature and humidity throughout the warehouse.

Indoor layout: The indoor layout and obstacles (such as grain piles, equipment, etc.) can affect the propagation path and speed of 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 ventilation exit

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

Distance between the air supply outlet and ventilation exit: The farther the air supply outlet is from the ventilation exit, 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 reduced air velocity and diminished air supply effectiveness.
