摘要： PURPOSE:To execute the control with high accuracy by fetching the optimum control value as an operating signal by a regulator having a deviation value calculated by a computer controller and having a PI or PID operation, and operating each valve by this signal. CONSTITUTION:When a program is stored in a computer controller 14 by a kind, quantity, etc. of goods contained in advance in a refrigerating chamber, the controller 14 inputs a deviation value calculated by calculating in a complicated high level each value of TA, TB and TS converted to an electric signal by an R/L converter 15, to temperature controllers 16-18, deviation between a set value of each controller 16-18 and this deviation value is controlled by a PI or PID operation, an output of each controller 16-18, being an optimum control value is inputted as an operating signal of electronic temperature expansion valves 5, 6 and an electronic evaporation pressure adjusting valve 7, each valve 5-7 is operated, and a blow-out temperature of air cooling chambers 1, 2 is controlled with high accuracy in accordance with a program prescribed in advance.
