PROBLEM TO BE SOLVED: To effect control efficiently, precisely, and in a stable and energy- saving manner by slightly utilizing a control technology. SOLUTION: In the control device for refrigeration cycle of air conditioner the refrigeration cycle is divided into a high pressure side and a low pressure side by a compressor and an expansion member. And the control device comprises high pressure side control units 8-12 to control one or more high pressure side device constituent elements and low pressure side control units 1-7 to control one or more low pressure side device constituent elements. At least one influencing amount (ys) of the control units 1-7 constitutes a connecting amount, and the connecting amount is inputted and connected to the control units 8-12 so as to serve as an influencing amount, whereby both the control units are connected together. For example, the control units are used in a carbon dioxide gas air conditioner of automobile. |
