Claim:
1. A control apparatus for a cooling system having a low-temperature showcase and a refrigerating machine for supplying refrigerant to the low-temperature showcase, the control apparatus comprising a data base having environmental condition cells at which control values for the refrigerating machine are respectively registered in association with respective environmental conditions, wherein according to a present cooling state of the low-temperature showcase, the control apparatus outputs a control value suitable for the present cooling state to the refrigerating machine, registers the control value in an environmental condition cell conformed with the present environmental condition and changes the control value to thereby construct the data base, and when the environmental condition varies, the controller refers to an environmental condition cell conformed with the environmental condition, corrects a control value registered at the environmental condition cell in accordance with a tendency that the control value has been hitherto changed, and outputs the corrected control value to the refrigerating machine, wherein a control value at a new environmental condition cell to be newly referred to is corrected in accordance with the relationship between a control value at a previous environmental condition cell that has been hitherto referred to and the control value at the new environmental condition cell to be newly referred to and a tendency of change of the control value at the previous environmental condition cell.
