    • PURPOSE:To obtain the air conditioning system suitable for a building with small heat energy loss and the like by a method wherein the introduction of outside air is controlled in response to CO2 concentration in return air or, during pre-heating or pre- cooling operation, in response to the enthalpies of return air and outside air or the like. CONSTITUTION:The outside air taken in from an outside air intake port 8 by the action of a intake air blower 11 is introduced through an enthalpy exchanger 14, an intake damper 15, an intake air chamber 6, an air filter 9, a cold water coil 10 and an intake air duct 26 from respective blowoff slots 25 into a room 1. After that, the air in the room 1 is lead through exhaust slots 27, a return air duct 28, an air filter 12 and a return air blower 13 into a return air chamber 5. A part of the air in the return air chamber 5 is flowed through a return air damper 17 into the intake air chamber 6 in order to join to the outside air, while the remaining part of the air in the return air chamber 5 is discharged through an exhaust gas damper 16 and the enthalpy exchanger 14 into the atmosphere. Furthermore, during pre-cooling or pre-heating operation, the respective dampers 15-17 are controlled by opening and closing in response to the outputs of the respective enthalpy detectors 20 and 22 of return air and outside air.
