ABSTRACT:
A refrigerant evaporator for an air conditioning and ventilating system for a motor vehicle has an evaporator with an air inlet face which receives a non-uniform air flow pattern from a radial air blower of the ventilating system and which evaporator further includes refrigerant passes with flow areas and volumes selected to contract the refrigerant flow at the outlet of the evaporator thereby to produce more refrigerant cooling in the portion of the evaporator core which receives higher air flow so as to produce a more uniform outlet air temperature from the evaporator.
