PROBLEM TO BE SOLVED: To provide a cooling system which can continue service even during defrosting. SOLUTION: A cooling cycle 80 is provided with first and second evaporators 11 and 12 connected in series while sandwiching a pressure reduction mechanism 13 therebetween, and a cooling unit 10 provided with a change-over valve 14 which switches a supply direction of a refrigerant with respect to these evaporators. There can be provided a cooling system which can alternately bring the evaporators 11 and 12 in a service state as being capable of bringing the one evaporator in a cooling service state and the other evaporator in a defrosting state only by changing the flow of the refrigerant, and is compact and can supply cool air continuously using an evaporator having a narrow fin pitch since it is unnecessary to prevent the reduction in abilities caused by ice accretion.
