Abstract

본 발명은 이중 증발기를 사용하는 냉장고의 냉매 사이클에 관한 것이다. 종래 기술에 따른 냉장고에서는 증발기의 제상시에 히이터(heater)를 사용하고 있으므로 증발기의 제상시에는 필연적으로 냉장고의 온도가 상승하게 된다. 이에 따라, 냉장고 내에 냉장 중인 식품 등이 녹았다 얼었다하여 식품의 냉장보관상태에 악영향을 미치게 된다. 따라서, 본 발명의 목적은 증발기의 제상시에도 냉장고 내의 온도 상승을 일으킴이 없이 제상을 실행할 수 있는 이중 증발기를 사용하는 냉장고의 냉매 사이클을 제공하는 것이다. 이와 같은 목적은 달성하기 본 발명에서는, 압축기, 응축기, 모세관, 증발기, 및 액분리기를 포함하는 냉장고의 냉매 사이클에 있어서, 상기 응축기와 모세관 사이에 개재하는, 액체상태의 냉매와 기체상태의 냉매를 분리하는 수액기; 상기 액체상태의 냉매를 상기제1증발기에 공급하는 제1모세관을 우회하며, 상기 수액기로부터 기체 상태의 냉매를 상기 제1증발기에 공급하는 제1모세관을 우회하며, 상기 수액기로부터 기체상태의 냉매를 상기 제1증발기에 공급하도록 된 제1솔레노이드 밸브; 상기 제1증발기에 병렬연결되는 제2증발기; 상기 수액기로부터 상기 제2증발기에 액체상태의 냉매를 공급하는 제2모세관; 및 상기 제2모세관을 우화하며, 상기 수액기로부터 기체상태의 냉매를 상기 제2증발기에 공급하도록 된 제2솔레노이드 밸브를 더 포함하는 것을 특징으로 하는 이중 증발기를 사용하는 냉장고의 냉매 사이클을 제공한다.The present invention relates to a refrigerant cycle of a refrigerator using a double evaporator. In the refrigerator according to the related art, since a heater is used to defrost the evaporator, the temperature of the refrigerator inevitably increases during the defrost of the evaporator. Accordingly, the refrigerated food and the like in the refrigerator melts and freezes, which adversely affects the refrigerated state of the food. Accordingly, an object of the present invention is to provide a refrigerant cycle of a refrigerator using a double evaporator capable of performing defrosting without causing a temperature rise in the refrigerator even when defrosting the evaporator. In order to achieve the above object, in the present invention, in a refrigerant cycle of a refrigerator including a compressor, a condenser, a capillary tube, an evaporator, and a liquid separator, a liquid refrigerant and a gaseous refrigerant interposed between the condenser and the capillary tube are used. Separating receiver; Bypassing the first capillary for supplying the liquid refrigerant to the first evaporator, bypassing the first capillary for supplying the gaseous refrigerant to the first evaporator from the receiver, and from the receiver A first solenoid valve configured to supply a refrigerant to the first evaporator; A second evaporator connected in parallel to the first evaporator; A second capillary tube for supplying a liquid refrigerant from the receiver to the second evaporator; And a second solenoid valve configured to allegorize the second capillary tube and to supply a gaseous refrigerant from the receiver to the second evaporator. .
