PROBLEM TO BE SOLVED: To provide a minimum flow recirculation system of a scroll compressor arranged not only to prevent the heating of the high-temperature portion of the compressor above a set temperature but also to allow the reduction of manufacturing cost. SOLUTION: The minimum flow recirculation system of this scroll compressor is composed of the 1st connection route 100, designed to link a high-pressure space H and a low-pressure space L in a casing 10; the 2nd connection route 200, including a portion for linking the 1st connection route 100 and the low-pressure space L of the casing 10; a liquid coolant inflow guide tube 300, designed to guide the liquid-state coolant of the frozen cycle system to the low-pressure space L through the 2nd connection route 200; the 2nd connection route opening/closing means 400, arranged in the 1st connection route 100 and designed to open or close the 2nd connection route 200, based on the pressure difference between the low-pressure space L and the high-pressure space H; and a temperature detecting-type opening/closing means 500, installed within the 1st connection route 100 and designed to open or close the 1st connection route 100, based on the temperature of the high-pressure space H.
