Vehicle Thermal Management_Refrigerant loop_1_Low.jpgWith LMS Imagine.Lab Refrigerant Loop the design of AC loops can be studied and performed. The climate control system has become one of the most important features in automotive comfort, and the refrigerant loop significantly influences fuel consumption and pollutant emissions. LMS Imagine.Lab Refrigerant Loop comes with a dedicated set of tools and libraries for pressures, temperatures, flow rates, prediction, heat exchangers characterizations, component performance optimization, Coefficient of Performance calculation, and drive cycle analysis.


A new step in the understanding of the transient behavior of refrigerant loops has been achieved, by making it possible to efficiently size components (heat exchangers, compressor, thermal expansion value), test alternative fluids (e.g. CO2) and optimize/evaluate new architectures (several stage compressors, multi-evaporator systems, heat pump systems).

Moreover, engineers can further investigate more global thermal issues associated with refrigerant loop behavior, such as developing and testing control strategies and studying the impact of the system on the engine thermal management.

LMS Imagine.Lab Refrigerant Loop gives engineers the ability to ascertain that the system performs to the highest standards for optimal passenger comfort regardless of operating conditions.
