In a refrigeration system, coolant is allowed to branch from a refrigeration circuit part between the midpoint of the condenser and the outlet of the pressure reducing pipe, and is subjected to pressure reduction by a pressure reducing unit to thereby obtain a cooling effect, the reduced temperature branched coolant being utilized to cool the remaining coolant in a refrigeration circuit part between the outlet of the condenser and the outlet of the pressure reducing pipe, whereby the amount of cooling at that time is controlled so that the flow rate of coolant in the refrigeration circuit is also controlled. The branched coolant is allowed to rejoin the refrigeration circuit part between the midpoint of the pressure reducing pipe and the midpoint of the evaporator, whereby the flow rate of coolant can be maintained suitable. Even if the branched coolant is not completely evaporated prior to recombining, no solution returns to the compressor, which contributes to stabilization of the system operation.
