1. An air conditioning system, comprising:
an outdoor unit including a compressor;
at least one distributor connected to the outdoor unit and including a condenser and an evaporator that exchange heat between refrigerant and water;
a plurality of heating pipes in communication with the condenser;
a plurality of cooling pipes in communication with the evaporator;
a plurality of fan coil units connected to the plurality of heating pipes or the plurality of cooling pipes; and
a controller configured to perform a heating pipe search operation for respectively matching a portion of the plurality of fan coil units with the plurality of heating pipes, and a cooling pipe search operation for respectively matching another portion of the plurality of fan coil units with the plurality of cooling pipes;
a plurality of temperature sensors respectively provided in the plurality of fan coil units;
a plurality of heating flow valves respectively installed in the plurality of heating pipes;
a plurality of cooling flow valves respectively installed in the plurality of cooling pipes, wherein the controller is configured to, after any one of the plurality of heating flow valves is opened, match a fan coil unit provided with a temperature sensor a sensed temperature of which rises by a set temperature or more among the plurality of temperature sensors with a heating pipe provided with the any one heating flow valve, and after any one of the plurality of cooling flow valves is opened, match a fan coil unit provided with a temperature sensor a sensed temperature of which drops by a set temperature or more among the plurality of temperature sensors with a cooling pipe provided with the any one cooling flow valve;
a first timer configured to measure search times respectively required for matching of the plurality of heating pipes;
a second timer configured to measure search times respectively required for matching of the plurality of cooling pipes; and
a storage unit configured to store search times measured by the first timer and the second timer.
