<p>An air conditioning system that can perform stable temperature/humidity control and in which the capacity of a freezing machine and energy consumption can be reduced. A cold water supply line (11) and a return cold-water supply line (12) are connected to a cooling-cum-heating coil (3). A warm water supply line (14) is connected to a heating coil (5). The amount of water supplied from the cold water supply line (11) or the return cold-water supply line (12) to the cooling-cum-heating coil (3) is controlled so that the humidity of air to be treated is a desired set humidity. When the amount of humidification is insufficient, the amount of warm water supplied from the warm water supply line (14) to the heating coil (5) is controlled. Further, the amount of water supplied from the cold water supply line (11) to the cooling-cum-heating coil (3) and the amount of return cold-water supplied from a return cold-water supply line (18) to a reheating coil (6) are controlled so that the temperature of the air to be treated is a desired set temperature. When the amount of reheating heat is insufficient, the amount of warm water supplied from the warm water supply line (16) to a second reheating coil (7) is controlled.</p> |
