REFRIGERATOR ENABLE TO CONTROL REFRIGERANT CIRCULATION QUANTITY AND CONTROL METHOD FOR CONTROLING REFRIGERANT CIRCULATION QUANTITY

摘要

PURPOSE: A refrigerator for controlling a refrigerant circulation quantity and a controlling method a refrigerant circulation quantity of a refrigerator is provided to control a refrigerant quantity which is injected to the difference between the outside of the temperature of a refrigerator and an inside temperature, to effectively control the circulation quantity of the refrigerant. CONSTITUTION: A refrigerator for controlling a refrigerant circulation quantity comprises a compressor(10), a condenser(20), a capillary tube(30), and an evaporator(40). The compressor inhales a refrigerant vapor of the low temperature and low pressure and makes vapor of the high temperature and high pressure. The condenser releases heat of the refrigerant of high temperature and high pressure which is discharged from the compressor to water or air. The capillary tube expands a high pressure saturated liquid which is discharged from the condenser to the refrigerant of the low temperature and low pressure. The capillary tube comprises a plurality of the capillary tubes which is the reciprocal length. The evaporator discharges a cold air into storage of the refrigerator by a heat exchange with the refrigerant.
