PURPOSE:To establish a great amount of energy saving by a method wherein the carrying system of water serving as heat source and the carrying system of air are properly controlled in an air conditioning system employing water as heat source. CONSTITUTION:A temperature detector 9 to detect the temperature of the water serving as heat source passing through the coil 3 of each system is mounted on the branch pipe 10 of a return pipe of the water serving as heat source. When cold water operation or hot water operation is intended, the coil, from which the water serving as heat source with the highest temperature or lowest temperature leaves, is detected out of the coils 3 of the respective air conditioners. If the temperature of the detected coil 3 exceeds the set value or is below the set value, the water feeding capacity of a pump 6 is increased so as to bring said temperature to the set value. In addition, an air passage 16, through which air is sucked in a fan 4 by by-passing the coil 3, is provided parallel to the coil 3 and a damper 17 is interposed in the passage 16. The damper 17 is open and closed so as to control the air temperature on the discharge side of the fan 4 to be brought to the set temperature. |
