Abstract
The invention refers to a controller for controlling operation of a refrigerant circuit, which refrigerant circuit comprises a compressor arrangement, a heat releasing heat exchanger heating an external medium, for example ambient air, a heat absorbing heat exchanger cooling a flow of gaseous medium through said heat absorbing heat exchanger for cooling cargo arranged in a storage volume, in particular a refrigerant circuit for transport refrigeration.

Controller for controlling operation of a refrigerant circuit, which refrigerant circuit comprises a compressor arrangement, a heat releasing heat exchanger heating an external medium, a heat absorbing heat exchanger cooling a flow of gaseous medium through said heat absorbing heat exchanger for cooling cargo arranged in a storage volume, in particular a refrigerant circuit for transport refrigeration,
- said controller controlling at least one of
- a first actuator driving said compressor arrangement such that a first parameter detected by said controller meets a predefined first parameter setting associated with said compressor arrangement,
- a second actuator driving a blower arrangement associated with said heat releasing heat exchanger such that a second parameter detected by said controller meets a predefined second parameter setting associated with said heat releasing heat exchanger and
- a third actuator driving a blower arrangement associated with said heat absorbing heat exchanger such that a third parameter detected by said controller meets a predefined third parameter setting associated with said heat absorbing heat exchanger.
