    While discussing the use of CO2 as a refrigerant: The technician with correct approach.

    Explanation

    Given information:

    Technician A says that it is non-toxic and presents little threat to the environment.

    Technician B says that only slight changes from conventional system are required because CO2 systems operate at low temperature and pressure.

    In an automobile, the air conditioning system is used to remove heat from the passenger compartment and moved to outside of the vehicle. To remove this heat, the substance used by an air-conditioner system is termed as refrigerant. As the refrigerant is used to cool the interior of the vehicle, it absorbs and releases heat with the help of different system components. Today almost all vehicles used R-134 refrigerant that causes less damage to the ozone layer when released into the atmosphere...
