HVAC and Cabin Comfort Modeling for xEVs

Register for this event with our India GT Conference 2020.

Note that this is a paid event, and the cost in INR with payment instructions are mentioned below.

This class is intended for users with previous experience of GT-SUITE.

This two-day class will introduce the use of GT-SUITE software for modeling of air conditioning systems, including the refrigerant circuit and cabin.  The course is targeted towards engineers with responsibility for design and analysis of A/C systems, or for those who are responsible for overall vehicle energy management including an A/C system.

The class will consist primarily of interactive model building exercises.  The following are the primary topics to be covered:

Modeling the refrigerant flow network:  The participant will learn how to build a model of the refrigerant flow network by two methods.  First, the participant will learn how to build flow components manually to understand basic modeling and discretization concepts.  Second, the participant will learn how to quickly and easily transform a 3D CAD geometry file into a 1D flow network in GT-SUITE using the pre-processing tool GEM3D.

Modeling A/C system components:  The participant will learn how to build and calibrate the basic components of A/C systems, such as compressor, receiver/dryer, thermal expansion valve, and heat exchangers.  The participant will also learn how the COOL3D pre-processing tool can be used to build and automatically discretize more complex scenarios (for e.g. non-uniform inlet air flow, stack of heat exchangers, etc.).

Assembling the complete A/C system model for system level calculations:  The participant will learn how to assemble the refrigerant flow network and A/C components into a complete model of the A/C system. Steady state and transient analysis of this system will be discussed.  The participant will learn the basics of the GT-POST post-processing tool for all analysis of results.

Modeling the vehicle cabin:  The participant will learn about the different levels of modeling detail available for modeling the cabin within GT-SUITE.  The use of COOL3D to create a detailed 3-D cabin model will be discussed.

Modeling the Chiller refrigerant side circuit for xEVs: This is particularly important when it comes to xEVs where the refrigerant is divided into two parallel circuits one catering to the cabin comfort and other to battery cooling. And it is important to strike a balance between the two through controls. The participant will learn about modeling the above and the basic controls.

Integration with Cooling/Engine/Vehicle models:  The participant will understand the capabilities of GT-SUITE to integrate A/C system models into larger vehicle system level simulations that may include cooling circuits, driveline systems and others.  Cabin pulldown transient simulations will be discussed, as well as transient drive cycle analysis for energy management. Please note that the coolant loop will not be modeled in the training.

Introduction to detailed Cabin modeling using GT-TAITherm: A demonstration of our new capabilities to model detailed velocity and temperature distribution in the cabin.

Computers and GT licenses will be provided for this training. If there are any questions about the content of this training, please contact the instructor.
