Hydrocarbon Zeotropic Refrigerant Application of Refrigerator

摘要

The present invention relates to a refrigerator using a saturated hydro-carbon non-azeotropic refrigerant mixture. The refrigerator using a saturated hydro-carbon non-azeotropic refrigerant mixture comprises: a refrigerant compressor compressing and discharging a non-azeotropic refrigerant mixture in a condensation pipe by a refrigerant compressor driving motor; a condensation pipe cooling blower releasing condensation heat to the condensation pipe; a fluid container installed in the lower part of the condensation pipe; and a capillary pipe transmitting non-azeotropic hydrocarbon mixture to a freezer chamber and a refrigerating chamber in the fluid container. The capillary pipe includes a control pipe connected to a freezer chamber cooling pipe and installed on an outer wall of the freezer chamber connected to the freezer chamber cooling pipe. The control pipe comprises a refrigerating chamber cooling pipe. The control pipe includes: the freezer chamber cooling pipe; the control pipe installed on the outer wall of the freezer chamber; the refrigerating chamber cooling pipe; and the capillary pipe. A mixing ratio, wherein saturated hydrocarbon which is two non-azeotropic matters in the condensation pipe is contained in a fluid state and a gas state of the saturated hydrocarbon in accordance with the temperature, is changed, so a component ratio of the two matters mixed in the liquid refrigerant mixture flowing into the evaporation pipe through the capillary pipe varies with a pressure change due to the change of the mixing ratio. Also, cooling efficiency is improved by varying a flow rate.
