A refrigerator comprising: a main body including a first storage chamber, a second storage chamber and a third storage chamber; a compressor connected with a compressor suction path and a compressor discharge path; a condenser connected with the compressor discharge path and a condenser outlet path; a first evaporator to cool the first storage chamber and connected with a first evaporator inlet path and a first evaporator outlet path; a first storage chamber fan; a second evaporator to cool the second storage chamber and connected with a second evaporator inlet path and a second evaporator outlet path; a second storage chamber fan; a third evaporator to cool the third storage chamber and connected with a third evaporator inlet path and a third evaporator outlet path; a third storage chamber fan; a path switching device connected with the condenser outlet path and the first evaporator inlet path, the second evaporator inlet path and the third evaporator inlet path, wherein the first evaporator outlet path and the third evaporator outlet path are connected to the compressor suction path and the second evaporator outlet path is connected to the first evaporator inlet path such that the first and the second evaporators (6, 7) are connected in series, and wherein the serially connected first and the second evaporators (6, 7) and the third evaporator are connected in parallel; and a controller configured to control the path switching device based on at least one mode from a first mode, a second mode and a third mode; characterized in that the controller is configured to selectively perform: the first mode to control the path switching device in a second evaporator supply mode such that refrigerant is supplied to both the first evaporator and the second evaporator and to operate the first storage chamber fan and the second storage fan; the second mode to control the path switching device in a first evaporator supply mode such that the refrigerant is supplied to the first evaporator and to operate the first storage chamber fan; and the third mode to control the path switching device in a third evaporator supply mode such that refrigerant is supplied to the third evaporator and to operate the third storage chamber fan. a main body including a first storage chamber, a second storage chamber and a third storage chamber;
