An air conditioning system for a communication equipment and a controlling method thereof are provided to prevent a component from being damaged and maintain the cooling state of a communication equipment stably by stopping the operation of an air conditioning system when there is a problem in the flow of coolants. An air conditioning system for a communication equipment includes: an indoor heat exchange(110); a circulation pipe line(130) through which coolants circulates; a circulation pump(132) which is installed at the circulation pipe line; an outdoor heat exchange(600) which is installed at an outdoor circulation pipe line; a bypass pipe line(140) which circulates coolants without using the outdoor heat exchange; bypass valves(152,154) which are installed at the circulation pipe line and the bypass pipe line; a first cooling unit(100) which consists of a first brown heat exchange shrouding a first heat exchange tube; a compressor(210) which changes the coolants into high temperature/pressure vapor; a condenser(220) by which heat exchange is enabled between the coolant passing the compressor and the outdoor air; an expansion valve(230) which changes the coolants from the condenser into low temperature/pressure liquid; and a second cooling unit(200).
