Abstract
The invention comprises an arrangement for controlling the flow of a coolant fluid in a compressor, in particular in a rotary compressor, in which a coolant-fluid inlet for coolant fluid discharged from the compressor and a coolant-fluid outlet for returning the coolant fluid into the compressor are provided. A fluid cooler is also provided through which, when necessary, part of the coolant fluid can be directed for cooling and a system-control actuator is used to control the magnitude of the proportion of the coolant fluid that is directed through the fluid cooler on the basis of system parameters, in particular on the basis of the temperature of the coolant fluid. In the invention a summer-/winter-operation actuator is provided, which can take priority over the system-control actuator so that in a summer position it completely or partially eliminates the action of the system-control actuator, in such a way that when the summer-/winter-operation actuator is activated, the proportion of the coolant flow that is directed through the fluid cooler is increased or reduced by a fluid-control device.
