1. A refrigerant control system for controlling a refrigerant flowing through a circulation passage connected to a compression section and circulating the refrigerant so as to exchange heat between a cooling target and the refrigerant compressed by the compression section, comprising:
a storing section which stores the refrigerant;
a first pipe which is connected to an outlet side pipe constituting the circulation passage and located on the side of an outlet of the compression section and flows the refrigerant in the outlet side pipe to the storing section through the first pipe;
a second pipe which is connected to an inlet side pipe constituting the circulation passage and located on the side of an inlet of the compression section and flows the refrigerant in the storing section to the inlet side pipe through the second pipe;
a first opening/closing valve which is provided in the first pipe and is capable of switching whether to flow the refrigerant in the outlet side pipe to the storing section;
a second opening/closing valve which is provided in the second pipe and is capable of switching whether to flow the refrigerant in the storing section to the inlet side pipe; and
an opening/closing control section which controls an opening/closing state of the first opening/closing valve and the second opening/closing valve on the basis of a setting temperature of the cooling target set according to a predetermined method.
