In a fast-paced and ever-changing world, HVAC product design must also be fast, accurate and complete from concept to commissioning. The Software in the Loop (SIL) process emerges as critical in enabling seamless collaboration between software developers, lab technicians and field engineers through the use of a unified toolset.

This paper explores application development through STone, CAREL's new software development ecosystem. The powerful features of the new environment make it possible to approach the development of a new thermodynamic machine, from function to commissioning, in a fast, efficient, collaborative manner. Starting with the thermodynamic design of the units and devices in MATLAB, passing through the implementation of the software logic conforming to IEC 6113 ...
