- Generally, a refrigerator comprises a cabinet forming a storage compartment, a door provided at the cabinet to open and close the storage compartment and a cooling system cooling the storage compartment to keep foods at proper temperature.
- As shown in
FIG. 1 , such a conventional cooling system comprises acompressor 101 compressing a gas refrigerant at low pressure and low temperature to a gas refrigerant at high pressure and high temperature, acondenser 102 condensing the refrigerant supplied from thecompressor 101 to a liquid refrigerant, acapillary tube 103 converting the refrigerant from thecondenser 102 into low pressure and mid temperature refrigerant, and anevaporator 104 cooling surrounding air while gasifying the refrigerant supplied from thecapillary tube 103. Also, the cooling system further comprises adryer 105 between thecondenser 102 and thecapillary tube 103, which accordingly forms a closed loop so that the refrigerant is supplied from thecondenser 102 in thedryer 105 to remove moisture, and introduced to theevaporator 104 and thecompressor 101, in regular sequence. - With this configuration, a storage compartment of a refrigerator is cooled and maintains freshness of foods.
- However, in such a conventional cooling system, the amount of the liquid refrigerant introduced to the
dryer 105 through thecondenser 102 is fluctuated according to conditions of cooling cycle. At this time, as shown inFIG. 2A , the liquid refrigerant introduced to thedryer 105 is filled up over an upper end of thecapillary tube 103 inserted to a lower side of thedryer 105. Next, as shown inFIG. 2B , the liquid refrigerant filled up over the upper end of thecapillary tube 103 flows to thecapillary tube 103. Then a water level of the liquid refrigerant falls again below the upper end of thecapillary tube 103. After this, repeating such a procedure, the liquid refrigerant flows periodically to thecapillary tube 103. Then, an outflow amount of the liquid refrigerant flowing to thecapillary tube 103 is fluctuated according to the amount of the liquid refrigerant introduced to thedryer 105.

- As shown in
FIGS. 3 and 4 , a refrigerator according to an embodiment of the present invention comprises acabinet 20 having a freezing compartment (not shown) and a refrigerating compartment (not shown) partitioned from side to side; a freezing compartment door (not shown) and a refrigerating compartment door (not shown) provided at thecabinet 20 to open and close the freezing compartment and the refrigerating compartment respectively; and a cooling system cooling the freezing compartment and the refrigerating compartment so as to keep foods of the freezing compartment and the refrigerating compartment in proper temperature. - The cooling system comprises a
compressor 1 compressing a gas refrigerant at low pressure and low temperature to be changed into high pressure and high temperature, acondenser 2 condensing the refrigerant supplied from thecompressor 1 to a liquid refrigerant, acapillary tube 15 converting the refrigerant from thecondenser 2 into low pressure and mid temperature, an evaporator 9 cooling surrounding air while evaporating the refrigerant supplied from thecapillary tube 15, adryer 5 provided on a refrigerant line connecting thecondenser 2 and thecapillary tube 15 to remove impurities included in the refrigerant from thecondenser 2, and amuffler 6 provided on a refrigerant line connecting thedryer 5 and thecapillary tube 15 to reduce a range of fluctuation of the amount of liquid refrigerant flowing from thedryer 5 to thecapillary tube 15. Also, the cooling system further comprises anaccumulator 10 provided at a refrigerant line from the evaporator 9 to thecompressor 1 to separate a gas-liquid mixed refrigerant from the evaporator 9. - The evaporator 9 is provided at a rear of the
cabinet 20, and comprises a refrigeratingcompartment evaporator 7 forming cool air in the refrigerating compartment and afreezing compartment evaporator 8 forming cool air in the freezing compartment. Also, at the rear of thecabinet 20, it is preferable to provide a refrigerating compartment fan 7 a and a freezing compartment fan 8 a forcibly ventilating cool air generated at the refrigeratingcompartment evaporator 7 and thefreezing compartment evaporator 8 into the refrigerating compartment and the freezing compartment respectively (refer toFIG. 5 ). - Generally, phase of a refrigerant is changed through the
compressor 1 and thecondenser 2, and then the refrigerant flows to the evaporator 9 through thedryer 5 and thecapillary tube 15. At this time, according to a condition of cooling cycle, the amount of liquid refrigerant introduced to thedryer 5 through thecondenser 2 is fluctuated. Also, according to the amount of liquid refrigerant flows in thedryer 5, the amount of liquid refrigerant flowing to thecapillary tube 15 is fluctuated. By such a fluctuation, the liquid refrigerant flowing intermittently to aninlet end 15 a of thecapillary tube 15 causes irregular refrigerant noise while passing through a connecting part of the evaporator 9, which diameter thereof is larger than that of an outlet end of thecapillary tube 15. That is, if both the refrigerating compartment fan 7 a and the freezing compartment fan 8 a operate, there is little refrigerant noise at a connecting part of the refrigeratingcompartment evaporator 7 because most of liquid refrigerant flows into thedryer 5. However, if either the refrigerating compartment fan 7 a or the freezing compartment fan 8 a operates, the relatively small amount of the liquid refrigerant and the gas refrigerant are mixed with each other, and introduced to thedryer 5. By such a fluctuation of the amount of liquid refrigerant, refrigerant noise occurs at the outlet end of thecapillary tube 15 and the connecting part of the refrigeratingcompartment evaporator 7. Themuffler 6 decreases fluctuation of the amount of liquid refrigerant flowing from thedryer 5 to thecapillary tube 15 to reduce refrigerating noise generating the connecting part of the evaporator 9. - The
compressor 1 and thecondenser 2 are arranged in a machine room provided at a lower rear of thecabinet 20. - The gas refrigerant not being liquefied at the
condenser 2 in time is phase changed into liquid refrigerant by acluster pipe 3 to flow into thedryer 5. At this time, a hot pipe 4 is connected to a refrigerant line between thecluster pipe 3 and thedryer 5 to prevent frost at an outer surface of a refrigerator. - An
outlet end 4 b of the hot pipe 4 is connected to aninlet 5 a of thedryer 5 to flow a refrigerant. Anoutlet end 5 b of thedryer 5 is coupled to aninlet 6 a of themuffler 6. It is preferable that anauxiliary capillary tube 12 is connected between theoutlet 5 b of thedryer 5 and theinlet 6 a of themuffler 6. Also, theauxiliary capillary tube 12 is the same as thecapillary tube 15 to save production costs. However, not being limited to this, theoutlet end 5 b of thedryer 5 and theinlet end 6 a of themuffler 6 may be connected in various ways. - The
dryer 5 removes impurities such as moisture included in the refrigerant which has passed through thecompressor 1, thecondenser 2, thecluster pipe 3 and the hot pipe 4. For example, Kaolin is provided in thedryer 5 to absorb moisture included in a refrigerant. - The
muffler 6 decreases refrigerant noise generated in the connecting part of therefrigerating compartment evaporator 7 by reducing fluctuation of the amount of liquid refrigerant flowing from thedryer 5 to thecapillary tube 15 thereby increasing indoor quietness. Here, it is preferable that themuffler 6 is provided as an accumulator. The accumulator used as themuffler 6 decreases refrigerant noise by reducing fluctuation of the amount of liquid refrigerant flowing to thecapillary tube 15, but anaccumulator 10 provided on a cooling line from the evaporator 9 to thecompressor 1 separates a gas-liquid mixed refrigerant from the evaporator 9. Here, themuffler 6 is arranged in a line with thedryer 5, but arrangement of the dryer and the muffler may change variously according to a structure of a refrigerator. - As shown in
FIG. 4A , the inlet end 15 a of thecapillary tube 15 is inserted into theoutlet end 6 b of themuffler 6, but as shown inFIG. 4B , aninlet end 115 a of acapillary tube 115 is coupled to theoutlet end 6 b of themuffler 6. Thus, a coupling structure of the inlet end 15 a, 115 a of thecapillary tube outlet end 6 b of themuffler 6 may change variously. - By such a configuration, the cooling system of the refrigerator according to an embodiment of the present invention is illustrated schematically by referring to
FIG. 5 as follows. - First, if gas refrigerant that has been compressed to be changed into high pressure and high temperature at the
compressor 1 flows into thecondenser 2, thecondenser 2 condenses a gas refrigerant at high pressure and high temperature to a liquid refrigerant at high pressure and low temperature. After that, gas refrigerant not being liquefied at thecondenser 2 is liquefied through thecluster pipe 3 and then flows in thedryer 5 through the hot pipe 4. The refrigerant flowed in thedryer 5 flows to themuffler 6 through theauxiliary capillary tube 12. Then, the liquid refrigerant jetted after flowing out of theauxiliary capillary tube 12 is received at a lower part of themuffler 6, slowing down speed. Therefore, although the liquid refrigerant flows irregularly from thedryer 5 to theauxiliary capillary tube 12, the range of fluctuation of the amount of liquid refrigerant may decrease because of slowing down speed by themuffler 6 and then flowing to thecapillary tube 15. Accordingly, at the outlet end of thecapillary tube 12, a regular amount of liquid refrigerant may flow in therefrigerating compartment evaporator 7 to reduce refrigerant noise generated at the connecting part of therefrigerating compartment evaporator 7. After that, the refrigerant flowed in therefrigerating compartment evaporator 7 flows in theaccumulator 10 through the freezingcompartment evaporator 8. Finally, the gas-liquid mixed refrigerant is separated at theaccumulator 10 to return the gas refrigerant alone to thecompressor 1 through a suction pipe 11 (FIG. 3 ). -
