(54) Refrigerator and method of controlling operation thereof


(57) A refrigerator in which an evaporator (32,34) is separately installed in each of a freezing chamber (12) and a refrigerating chamber (14) such that operations of the freezing chamber and the refrigerating chamber are independently controlled, and a method of controlling an operation thereof. An operation of the freezing chamber is performed first when the refrigerator starts to be operated in a parallel cycle to convert a flow of a refrigerant such that operations of the freezing chamber and the refrigerating chamber are independently performed using a 3-way valve (26), thereby achieving energy savings. Further, a check valve to prevent the refrigerant from flowing to a freezing chamber evaporator is omitted, thereby achieving production cost reduction.
