<P>PROBLEM TO BE SOLVED: To prevent a cooling capacity from being decreased, which is caused by the decrease of the amount of heat exchange between fins and air, when the amount of air flowing through the cooler is decreased by that a water vapor in the air passing the cooler (heat exchanger) becomes frost and deposits on the surface of the fins. <P>SOLUTION: A refrigerator includes: a heat exchanger 15 with the fins 23 for exchanging heat between the fins and the inflow air; a bypass air passage 81 connected with the vicinity of a heat exchanger outlet while an inlet is disposed in the vicinity of a heat exchanger inlet; and a bypass opening and closing unit 82 for continuously opening and closing the bypass air passage according to a differential pressure, which is caused between the inlet vicinity and the outlet vicinity of the heat exchanger, by the frost generated in the fin of a heat exchanger windward. <P>COPYRIGHT: (C)2013,JPO&INPIT |
