Abstract

본 발명은 냉장고의 초기 기동시 냉장실의 풍량을 가변시켜서 냉동실의 냉각속도를 신속하게 상승시킬 수 있으므로써 냉각 효율을 증대시킬 수 있으며, 압축기에서의 불필요한 일량을 줄여 압축계수를 증가시킬 수 있으므로 인해 사용 소비전력을 감소시킬 수 있는 등의 많은 장점이 구비된 것이다.The present invention can increase the cooling efficiency by varying the air volume of the refrigerator compartment at the initial startup of the refrigerator to increase the cooling speed of the freezer compartment quickly, and can be used because it can increase the compression coefficient by reducing unnecessary work in the compressor Many advantages, such as the power consumption can be reduced.

이를 위해, 본 발명은 냉동실과 냉장실에 각각 냉동실과 냉장실의 온도 제어를 흡열로서 이루어지도록 하기 위해 장착되는 제1, 2증발기(1) (2)와, 상기 냉동실과 냉장실에 각각 설치되어 압축기(3)의 운전시 연동되어 회전하는 냉동 및 냉장실 팬(4) (5)과, 상기 제1, 2증발기(1) (2)와 압축기(3)의 사이에 설치되어 냉매의 상을 분리하기 위한 기액 분리기(5)와, 상기 기액 분리기(5)와 압축기(3)의 사이에 설치되어 냉동 및 냉장실의 운전을 제어하여 냉장실의 제2증발기(2)로 흐르는 냉매의 압력을 측정하기 위한 압력 스위치(7)와, 상기 압력 스위치(7)에서 측정된 압력을 제어하기 위한 개폐수단으로 구성된 냉장고의 풍량 가변장치이다.To this end, the present invention is the first and second evaporators (1) and (2) are mounted in the freezer compartment and the refrigerating compartment, respectively, so as to achieve temperature control of the freezer compartment and the refrigerating compartment as endothermic, respectively, and the compressor (3) Gas-liquid installed between the freezing and refrigerating compartment fans (4) (5) and the first and second evaporators (1) (2) and the compressor (3) which rotate in synchronization with the operation of A pressure switch installed between the separator 5 and the gas-liquid separator 5 and the compressor 3 to control the operation of the refrigerating and refrigerating chamber to measure the pressure of the refrigerant flowing to the second evaporator 2 of the refrigerating chamber ( 7) and a flow rate variable device of the refrigerator composed of opening and closing means for controlling the pressure measured by the pressure switch (7).
