Abstract:
A chilling system comprising:a load; a chilling circuit for chilling the load with a refrigerant; a heat-dissipating mechanism for dissipating heat of the refrigerant in the chilling circuit to the outside; a refrigerant tank connected to said chilling circuit via a confluent valve; a chiller for maintaining the refrigerant stored in said refrigerant tank at a predetermined temperature; a controller for controlling the degree of valve opening of said confluent valve; and a temperature sensor for detecting a temperature of the refrigerant in said chilling circuit, wherein when said temperature sensor detects that a temperature of the refrigerant in said chilling circuit exceeds a predetermined temperature, said controller opens said confluent valve in order to mix the refrigerant in said refrigerant tank with that in said chilling circuit, and when the refrigerant stored in said refrigerant tank is maintained at a temperature within a predetermined range, said chiller stops its operation.
