PROBLEM TO BE SOLVED: To suppress a temperature rise even if the inside of a chiller installed outdoors is in an environment that a temperature rises, to avoid the lowering of a cooling capacity, and to avoid the deterioration of parts and an unintended operation stop of the chiller.SOLUTION: In a chiller M which is formed by arranging, in a cabinet 2, at least a heat exchanger, a cooling function part connected to the primary side of the heat exchanger, a cooling liquid circulation system which is connected to the secondary side of the heat exchanger and can make the cooling liquid circulate, and a control function part 6 for performing the temperature control of the cooling liquid by controlling the cooling function part, there is set a monitoring condition with respect to one or two or more monitoring elements for monitoring a change of the temperature of the inside of the chiller in advance when preventing an internal temperature rise, a change of the monitoring element is monitored at the operation of the chiller M, and when the change satisfies the monitoring condition, the surface of the cabinet 2 and/or the periphery of the cabinet 2 is cooled by water Lwm (containing cooling water Lw). |
