A refrigeration apparatus for chilling a storage chamber comprising air moving means for moving air through an air permeable refrigerant evaporator for chilling air flowing into the chamber and a duct air bypass exteriorly of the evaporator for flowing air around the evaporator in the region of the air entrance thereto and then back into the evaporator prior to the exit thereof in order to provide continuous flow and chilling of air through the exit portion of the evaporator in spite of frost accumulation on the evaporator. A method of chilling air in a storage space comprising directing the air from the space through a subfreezing chilling means having an entrance and an exit and bypassing the air around this entrance and back into the chilling means upon accumulation of frost at the entrance with the result that the chilling of the air is continued during the accumulation of the frost and prior to its eventual removal.
