PURPOSE:To provide a thermo-hygrostat capable of controlling the temperature and humidity in a container box in a short time. CONSTITUTION:The humidity and temperature in a container box 4a are detected by a humidity sensor 22 and a temperature sensor 20 attached to the inner wall of a container box 4a made of heat-transmission panels placed in a heat-insulation box 1 interposing a prescribed gap to form a cooling space S. The electric dampers 17, 18 placed at the exhaustion port 16 and the suction port 15 connecting the container box 4a and the cooling space S are opened by a controller 27 according to the detection signals transmitted from the humidity sensor 22 and the temperature sensor 20 and a suction fan 23 attached to the suction port 15 and an exhaustion fan 25 attached to the exhaustion port 16 are driven to circulate the chilled air in the cooling space S into the container box 4a. |
