Display of Thermodynamic Data and Informative State Charts for Online and Offline Analysis

During the development and testing of all types of air conditioning and cooling systems, physical variables such as pressure and temperature are recorded at the test bench or test vehicle – usually together with other measured signals and internal controller values. To evaluate the system configuration and the employed components and coolants, engineers working in the field of air conditioning technology need specific ways of visualizing thermodynamic data.

With the option Thermodynamic State Charts for CANape, you can now also display thermodynamic data synchronized with other measured data and generate highly informative state charts for online and offline analysis.

Functions

The option Thermodynamic State Charts makes it possible to generate individually designed thermodynamic state charts in just a few clicks. These simplify the online analysis of automotive cooling cycles, for example. You can choose between the following types of chart

• Pressure-enthalpy (ph),
• Pressure-specific volumes (pv),
• Pressure-temperature (pT),
• Temperature-enthalpy (Th)  
• Temperature-entropy (Ts)

When configuring your chart, you can choose from a wide range of materials and even mixed materials are possible. The variables that are relevant for the displayed state chart are calculated from the measured signals, for example for temperature and pressure, on the basis of the material data. It is possible to determine missing cycle reference points.
