The utility model relates to the field of granary comprehensive management, and provides an inner circulation
temperature control system of a
bungalow granary and the
bungalow granary. Comprising a fan which is movably arranged on the wall in the
bungalow granary and located above the surface of a grain
pile; the ventilation ground cage is arranged on the ground of the bungalow granary and located on the bottom face of the grain
pile; the ventilation pipeline penetrates through the grain
pile, one end of the ventilation pipeline is connected to the fan, and the other end of the ventilation pipeline is connected to the ventilation ground cage; the control device comprises a box body, a control host, a temperature sensor and a
carbon dioxide sensor which are arranged in the box body, and a
humidity sensor arranged in the grain pile. According to the utility model, parameters of
carbon dioxide concentration,
humidity of grain piles and temperature are monitored to cooperatively control on and off of the fan, so that risks of heating,
insect attack or
mildew of grains can be foreseen,
cold air conveying is carried out in time to control the temperature, the real state of stored grains can be reflected more comprehensively, and supervision and management are facilitated.
