Abstract: A heat pump heat exchanger includes a first manifold, a second manifold spaced from the first manifold, a plurality of refrigerant tubes hydraulically connecting the manifolds, and a distribution tube disposed in the first manifold. The distribution tube includes an inlet end, a distal end opposite the inlet end, a plurality of orifices between the inlet end and the distal end. The distribution tube also includes a terminal aperture immediately adjacent the distal end, wherein the terminal aperture includes an open aperture area greater than any one of the open orifice area.

Abstract: A cooling storage evaporator system employs a pivoting frost control door upstream from an evaporator that, when closed, inhibits air from passing through a lower portion of the evaporator. Closing the frost control door results in condensed water freezing on a lower portion of the evaporator when the AC is ON. When a vehicle engine is turned OFF when the vehicle stops in an idle condition, thereby turning the compressor OFF, the frost control door opens so that air passes over the evaporator, including the frozen portion thereof, melting the frozen condensed water to maintain the cool outlet air temperature at the vent.
