PURPOSE:To decrease a power loss and to improve comfortableness by accumulating a deviation between a cooling capacity control output and a set point, determining a goal adjustment quantity from the accumulated value and a dynamic model decided based on a control output and an air blasting quantity, and thereby controlling a refrigerating capacity. CONSTITUTION:A dynamic model is set by an air blasting quantity from an air blasting quantity detecting means M6 and is inputted into a control quantity operation means M9 in a model setting means M7. Concurrently, a physical quantity relating to a refrigerating capacity is inputted into the means M9 and a deviation accumulation means M8 from a detection means M4. A deviation with a target physical quantity inputted from a target setting means M5 is accumulated and is outputted into the means M9 in the means M8. A control quantity is decided from these input data and is outputted into a refrigerating capacity control device M3 in the means 9, and a refrigerator M2 is controlled. This constitution enables a control output variation in a transition period of a refrigerating cycle operation condition to be controlled and the control to be improved. |
