PROBLEM TO BE SOLVED: To provide a refrigeration unit that enables a refrigerant circuit to promptly return to a normal state when a control parameter excessively fluctuates to largely deviate from a control target value and that can maintain stable control at normal time of the refrigerant circuit.SOLUTION: An outdoor side control device 37 or indoor side control devices 47, 57, 67 are configured to detect excessive fluctuation that causes a control parameter to deviate from a target control value by a predetermined value or larger and to enable switching between a first operation amount change operation and a second operation amount change operation that are different operations for changing an operation amount. When the excessive fluctuation is not detected, the first operation amount change operation is used, and when the excessive fluctuation is detected, the first operation amount change operation is switched to the second operation amount change operation that enables the control parameter to come close to the control target value more promptly compared to the first operation amount change operation. |
