The stronger the sunlight intensity is, the higher the temperature in the granary 1 can rise, and meanwhile, the stronger the sunlight intensity is, the more electric energy generated by the solar panel 14 is, so that the circulation grain cooling machine 7 can work in a high-power state, the better the cooling effect of the circulation grain cooling machine 7 is, the temperature rise caused by sunlight in the granary 1 can be just made up, and the temperature in the granary 1 is always kept in a lower state.
Example 5:
example 5 is the same as example 4 except that:
in seventy or eighty months, the ambient temperature outside the granary 1 continuously rises, even if the temperature is kept high at night, the industrial air conditioner 6 also enters a working state, the industrial air conditioner 6 is connected with the commercial power and the solar panel 14, and the circulation grain cooling machine 7 is only connected with the solar panel 14. The industrial air conditioner 6 keeps the temperature in the granary 1 in a low state, and when the temperature in the granary 1 rises due to strong sunshine, the circulation grain cooling machine 7 is started to compensate the temperature rise of the temperature in the granary 1 caused by the sunshine, and the temperature in the granary 1 is always kept in a low state.
Example 6:
example 6 is the same as example 1 except that:
the grain storage system further comprises a temperature monitoring system, the temperature monitoring system comprises a plurality of temperature sensors, the temperature sensors are arranged outside the grain bin 1, in the bin space 4 and in the grain pile space 5 respectively, the temperature sensors in the grain pile space 5 are arranged on the upper portion, the middle portion and the lower portion of the grain pile space 5 respectively, the grain storage system further comprises an industrial air conditioner 6, and the industrial air conditioner 6 is arranged in the bin space 4 of the grain bin 1.
