Abstract

The present invention discloses a two-way variable air volume ventilation temperature control and humidification system for granaries and a control method of the two-way variable air volume ventilation temperature control and humidification system. The system comprises an air mixing box, a two-way ventilator, a ventilation pipe, a humidifier, a temperature and humidity detection cable and a measurement and control device. By analyzing temperature and humidity values of inside and outside of the granaries and different depths of grain piles measured by sensors on the temperature and humidity detection cable, when temperature control conditions are met, the system selects an open type or circulating type ventilation method, besides, forward or reverse rotations of the ventilator are utilizedto implement upward type or downward type ventilation, when humidification conditions are met, the humidifier is started, and besides, a frequency converter adjusts rotation of the ventilator to change air volume and humidification volume. The system operation and control method can control space temperature and humidity in the granaries or temperature and humidity of the grain piles within a setsafe storage temperature range and an equilibrium relative humidity range corresponding to safe storage moisture, thereby reducing quality deterioration and water loss during a grain storage period,reducing storage loss and ensuring safe grain storage.

Description

technical field [0001] The invention relates to the technical field of grain storage. More specifically, it relates to a two-way variable air volume ventilation temperature control and humidification system and control method for granaries. Background technique [0002] A granary refers to a building that is used to store grain and can meet the basic functional requirements for safe grain storage. During grain storage, it is necessary to control the moisture content of the grain within the safe moisture content and control the grain temperature below the safe storage temperature to ensure the safe storage of grain. In order to ensure the safety of grain storage in the granary, a supporting grain condition detection system is usually required to detect the grain condition while building the granary, and the supporting mechanical ventilation system is used to implement "temperature control" and "water control" measures and when there is heat, condensation, etc. Emergency tre...
