<P>PROBLEM TO BE SOLVED: To obtain an outside air introducing type air conditioning system capable of improving comfortability by preventing the blowoff temperature from rising and falling largely even when being operated with the air conditioning capacity near the lower limit. <P>SOLUTION: The outside air introducing type air conditioning system includes an outside suction port 5, a return suction port 4 for sucking indoor air, a switching damper 3 capable of selecting and introducing outside air or indoor air and an air conditioner (indoor machine 1) for cooling air from the switching damper and supplying the cooled air into a room. Further, the outside air introducing type air conditioning system includes an outside air sensor 12 for obtaining enthalpy of the outside air and an indoor sensor 8 for obtaining enthalpy of the indoor air and, when an air conditioner is operated near the lower limit of capacity of the air conditioner, further, lowers the air conditioning capacity and, thereupon, the enthalpy of the outside air is higher than the enthalpy of the indoor air, introduces at least a part of the outside air, at the same time, operates a compressor 14, cools air introduced to the air conditioner and, thereafter, supplies the cooled air into the room. <P>COPYRIGHT: (C)2012,JPO&INPIT |
