Abstract
In an air conditioning system, a cooling tower cools cooling water. A chiller generates cold water using the cooling water cooled by the cooling tower. A cooling water circulation passage circulates cooling water between the cooling tower and chiller. A first heat exchanger exchanges heat between air and the cold water generated by the chiller. A cold water circulation passage circulates the cold water between the chiller and first heat exchanger. A second heat exchanger exchanges heat between a portion of the cooling water cooled by the cooling tower and air heat-exchanged with the cold water. A cooling water branch passage, branching from the cooling water circulation passage, introduces to the second heat exchanger the portion of the cooling water introduced to the chiller from the cooling tower, and introduces to the cooling water circulation passage the portion of the cooling water heat-exchanged with air by the second heat exchanger.
