Abstract

본 발명은 냉장고용 냉동싸이클 및 그 냉동싸이클을 갖는 냉장고에 관한 것으로서, 증발기를 냉동실용과 냉장실용으로 각각 분할하여 상기 냉장실용 증발기와 냉동실용 증발기로 직렬로 연결 사용함에 따라 냉각효율이 향상되도록 하기 위해 압축기, 응축기, 팽창밸브, 증발기로 구성된 것에 있어서, 상기 증발기를 냉동실용 증발기와 냉장실용 증발기로 각각 양분하여 직렬 연결하여서 된 냉장고용 냉동싸이클을 제공함과 함께 상기 냉동싸이클에 의해 발생된 냉기의 흐름이 양방향으로 동시에 행하여 지도록 함에 따라 고내의 온도분포가 일정하게 유지되도록 하기 위해 냉동실의 상부에 냉동실용 증발기를 설치함과 함께 냉장실의 상부에는 냉장실용 증발기를 설치하고, 상기 냉동실용 증발기의 양측에는 냉동실용 팬을 설치함과 함께 냉장실용 증발기의 양측에는 냉장실용 팬을 설치하며, 상기 냉동실에는 냉동실 냉기순환통로를 형성함과 함께 냉장실에는 냉장실용 냉기순환통로를 형성하여 냉동실 및 냉장실용 증발기에서 발생된 냉기의 흐름이 각 냉동실용 팬 및 냉장실용 팬의 작동에 따라 전,후 양방향으로 행하여 지도록 한 냉장고를 제공한 것이다.The present invention relates to a refrigeration cycle for a refrigerator and a refrigerator having the refrigeration cycle. In order to improve the cooling efficiency by dividing the evaporator into a freezer compartment and a refrigerator compartment, and connecting the evaporator to the freezer compartment evaporator in series, A refrigeration cycle for a refrigerator comprising: a compressor, a condenser, an expansion valve, and an evaporator, wherein the evaporator is connected in series to a freezer chamber evaporator and a refrigerator chamber evaporator, respectively, and a flow of cold air generated by the freezing cycle In order to keep the temperature distribution in the hearth constant, the freezer chamber evaporator is installed at the upper part of the freezer compartment and the refrigerator compartment evaporator is installed at the upper part of the refrigerator compartment. In both sides of the freezer compartment evaporator, Install the fan and refrigerate And a cool air circulation passage for the refrigerator is formed in the refrigerator compartment so that the flow of cool air generated in the freezer compartment and the refrigerator compartment evaporator is transmitted to the freezer compartment fan and the freezer compartment fan, And the refrigerator is operated in both the forward and backward directions according to the operation of the refrigerator room fan.
