Vehicle Thermal Management

Heat Exchangers & Climate Control

By Dr. Gursaran D. Mathur

Operating thermal systems typically requires

a significant amount of energy, which could

adversely affect vehicle performance. To

provide customers the level of comfort that

they demand in an energy-efficient manner,

innovative approaches must be developed.

This book is an essential resource for engineers

and designers working on thermal systems,

presenting 45 of the most relevant technical

papers focusing on this important vehicle

SAE 2008 Alternate Refrigerant

Systems Symposium



Symposium Overview

As the need to control man-made greenhouse gasses (GHG) increases, the mobile air conditioning industry is taking

an active role in developing solutions. The 2008 SAE Alternate Refrigerant Systems Symposium will gather

industry leaders from around the world to address this important topic. SAE has been actively involved in this

important issue, and has supported related projects on an international level, including the Alternate Refrigerant

Cooperative Research Program, the Improved Mobile Air Conditioning Cooperative Research Program, and the

CRP 150 Cooperative Research for Refrigerants with GWP

Dear Symposium Participant,

As the symposium organizer, I would like to welcome you to the 9th Alternate

Refrigerant Systems Symposium. It’s been over a decade since the first

meeting was held to discuss a replacement refrigerant.

As we said last year there is not much time remaining for the world auto

industry to choose a new mobile A/C refrigerant to meet the 2011 European

Community (EC) F gas regulations. Currently there are still alternate refrigerant

choices, and raise the question if we will have a global or regional

replacement. The 2008 SAE Alternate Refrigerant Systems Symposium will

again gather industry leaders from around the world to address this important


The search for a global replacement refrigerant for HFC- 134a is complex and

mistakes could be costly. One replacement refrigerant may not answer the

world needs and multiple refrigerant systems may soon exist in the world

marketplace. It should be remembered that the early-1990’s changeover

from R-12 to R-134a cost the industry an estimated $8.5 billion and this

change could cost significantly more. After 15 years, considering a 3% inflation

rate, and not additional equipment technology costs, the global industry

expenditures are estimated to be in the range of $40 billion for a single

replacement refrigerant.

Ward Atkinson


Sun Test Engineering

SAE has been actively involved in this important issue, and has supported

related replacement refrigerant projects on an international level, including

the latest HFO1234yf Alternate Refrigerant Cooperative Research Programs,

I hope that you are more informed on the issues at hand once the symposium

Convergence 2008 is your connection to

emerging technologies, leading experts

and innovative organizations guiding

transportation electronics.

“Convergence 2008 will pose the question to the Vehicle

Electronics Industry, ‘Does this meet real customer

needs?’ It is no longer sufficient to simply add to the

extensive list of features available on today’s vehicle. As

witnessed with the revolution created by the iPod ® , the

magic lies in how effectively features are implemented,

creating the least amount of distraction with maximum

intuitiveness. The focus now moves from ‘what’ to ‘how’.”
