Investigation on CO2 gas cooler for Automobile air conditioning system

Homework Equations

I am trying to design a gas cooler for an automobile air conditioning system using CO2.

The Attempt at a Solution

I have conducted a literature review and understand the super and sub-critical cooling processes of CO2 and its potential to be used as a refrigerant especially within an air conditioning system getting rid of the more commonly used gases which are harmful to the evironment i.e CFC's. I am struggling to understand the design of the gas cooler and the heat transfer and pressure drop characteristics of a micro channel gas cooler within an automobile air conditioning system using CO2. If anyone could help me or point me in the right direction of some reading material I would be most grateful.

Thanks
Bryan

Dear Bryan,

Thank you for your interest in using CO2 as a refrigerant in automobile air conditioning systems. It is an important step towards reducing the harmful impact of CFCs on the environment.

Designing a gas cooler for an automobile air conditioning system using CO2 can be a challenging task, but with proper understanding and research, it is achievable. As you have mentioned, understanding the super and sub-critical cooling processes of CO2 is crucial. In addition, the heat transfer and pressure drop characteristics of a micro channel gas cooler should also be taken into consideration.

I would suggest looking into research papers and articles on CO2 gas coolers for air conditioning systems. Some good resources to start with are the International Journal of Refrigeration and the ASHRAE Journal. You can also reach out to experts in this field for guidance and advice. Additionally, computer simulations and modeling can also help in understanding the design and performance of the gas cooler.

I hope this helps and wish you all the best in your investigation.
