(54) | Refrigerator using non-azeotropic refrigerant mixture and control method thereof |
(57) A refrigerator using a non-azeotropic refrigerant mixture (NARM) and a control method
thereof. The refrigerator reduces the rotational speed of a freezing chamber fan or
stopping the freezing chamber fan for a designated time, and/or increasing the rotational
speed of a compressor in a simultaneous freezing/refrigerating operation mode of an
NARM cycle as compared to a freezing operation mode, and may thus decrease evaporation
latent heat of a refrigerant consumed by a freezing chamber evaporator and relatively
increase evaporation latent heat of the refrigerant usable in a refrigerating chamber
evaporator without increase in a charging amount of the refrigerant, thereby preventing
over-charging due to increase in the charging amount of the refrigerant and reducing
cycling loss.
