Summary:PROBLEM TO BE SOLVED: To provide a temperature controlling system of an agricultural greenhouse, for always keeping a temperature in a double layer agricultural greenhouse at plant raising temperature and humidity even at a high-temperature time in summer. SOLUTION: The temperature controlling system of the double layer agricultural greenhouse where an inner cover body and an outer cover body are doubly tightly stretched in an arch-like state at an interval and has an inner cover switching device opening and closing part of the inner cover body, and an outer cover switching device opening and closing part of the outer cover body. Furthermore, the system has a direct exhaust means for directly exhausting, if necessary, air in the inner and outer cover bodies in a condition of penetrating a normal direction of inner and outer cover bodies while opening and closing part of each of the inner and outer cover bodies. The system solves warm temperature accumulation of a ceiling part of the double layer greenhouse in a short time, improves an air conditioning efficiency in the greenhouse, and protects raising plants at abnormally high temperature.
