Homework Help: CO2 Gas cooler in Air conditioning

  1. Mar 14, 2012 #1
    1. The problem statement, all variables and given/known data

    Investigation on CO2 gas cooler for Automobile air conditioning system

    2. Relevant equations

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

    3. 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 any one could help me or point me in the right direction of some reading material I would be most grateful.
