Abstract
The invention relates to a centrifuge, in particular a continuous flow centrifuge, a biotechnical centrifuge or a blood centrifuge. The centrifuge comprises a refrigerant circuit. According to the invention, the outlet side of a controllable compressor is connected to an inlet side of an evaporator via a bypass line with a valve arranged therein. In a normal operation mode, a centrifuge vessel is cooled exclusively via the control of the compressor and an expansion unit while the valve is closed. If, on the other hand, a tolerance range of the target temperature in the centrifuge vessel is left, the valve is opened in order to bring about heating and thus a return of the temperature in the centrifuge vessel to the tolerance range.
