Abstract

The invention relates to a method for detecting a leak in a thermodynamic cycle device with a condenser for condensing vaporous working medium, comprising the following steps: determining sub-cooling of the working medium in the condenser, wherein sub-cooling is determined as a difference between a condensation temperature in the condenser and a temperature of a liquid working medium exiting the condenser; detecting a leak in the event that the sub-cooling determined differs from a setpoint value for the sub-cooling or in the event that a filling quantity of the working medium in the thermodynamic cycle device, being determined from the determined sub-cooling, differs from a setpoint value for the filling quantity. The invention further relates to a corresponding computer program product and to a corresponding device.
