The freezing chamber 10 and the refrigerating chamber 20 are divided and partitioned by the separating wall 16. Looking at the cold air supply structure, a part of the cold air cooled by heat exchange in the evaporator 3 through which the low temperature and low pressure refrigerant passes through Is forcedly blown by the blower fan 13 to be supplied to the freezing chamber 10 through a shroud 14, and a part of the remaining cold air is freely dropped through the shroud 14 so as to refrigerate the cold air guide flow path. It is guided to the refrigerating chamber 20 side through (15).
상기 냉장실(20)로의 냉기공급은 상기 본체(1)의 후방에 길이 방향으로 형성되며 상기 쉬라우드(14)와 상기 냉장실(20)을 연결하는 냉장실 냉기안내유로(15)를 통해 냉기가 자유낙하하고, 냉기안내유로(15)를 통해 자유 낙하된 냉기는 냉장실 냉기안내유로(15)에 접하는 냉장실 배면에 형성된 다수개의 냉장실 토출구(15a)를 통하여 상기 냉장실(20)로 공급되어 상기 냉장실(20) 내부를 냉각하도록 구성되어 있다.The cold air supply to the refrigerating chamber 20 is formed in the longitudinal direction at the rear of the main body 1, and the cold air is freely dropped through the refrigerating chamber cold air guide passage 15 connecting the shroud 14 and the refrigerating chamber 20.

상기와 같이 구성된 냉장고에 전원을 공급시키면 상기 냉장고의 내부에 장착되어 상기 냉동사이클을 구성하는 압축기가 구동되어 저온, 저압의 기체냉매를 고온, 고압의 기체냉매로 압축시키고 이 압축된 고온, 고압의 기체냉매는 응축기를 지나면서 고온, 고압의 액체냉매로 응축되어진다.When power is supplied to the refrigerator configured as described above, a compressor constituting the refrigeration cycle is driven inside the refrigerator to compress a low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant. Gas refrigerant is condensed into a high-temperature, high-pressure liquid refrigerant passing through the condenser.
상기 응축된 고온, 고압의 액체냉매는 팽창밸브를 거치면서 저온, 저압의 액체냉매로 변환되고, 상기 저온, 저압의 액체냉매는 상기 증발기(3)를 지나면서 저온, 저압의 기체냉매로 변환되면서 증발되고, 상기 증발기(3)의 증발작용에 의해 주위의 공기가 열 교환되어 주변의 공기를 냉각시키므로 냉기가 발생되는 것이다.The condensed high temperature and high pressure liquid refrigerant is converted into a low temperature and low pressure liquid refrigerant through an expansion valve, and the low temperature and low pressure liquid refrigerant is converted into a low temperature and low pressure gas refrigerant while passing through the evaporator (3).
