1. A chiller system comprising:
a plurality of chiller modules capable of performing a refrigeration cycle to supply cold water, the plurality of chiller modules including a first chiller module and a second chiller module, which are arranged in a row; a plurality of passages including a coolant inflow passage to allow coolant to be introduced into each of the first and the second chiller modules and a coolant discharge passage to allow the coolant to be discharged from the each of the first and the second chiller modules; a main control device that generates an operation signal to simultaneously or successively independently operate the first and the second chiller modules; a plurality of module control devices provided in each of the first and the second chiller modules that control an operation of each of the first and the second chiller modules, respectively, on the basis of the operation signal of the main control device; and a starting device communicably connected to the module control devices that selectively apply power to the first and the second chiller modules, wherein each of the first and the second chiller modules comprises:
a condenser and an evaporator;a support provided at both side of the condenser and the evaporator, the support comprising a condenser support that supports both sides of the condenser and an evaporator support that supports both sides of the evaporator;a coolant inlet that is disposed at the condenser support and connected with the coolant inflow passage; anda coolant outlet that is disposed at the condenser support and connected with the coolant discharge passage, wherein the condenser support of the first chiller module id coupled to the condenser support of the second chiller module.
