<p>The purpose of the present invention is to provide an outdoor-air treating air conditioner and a multi-air conditioning system using the outdoor-air treating air conditioner, which can prevent overcooling and overheating to improve the feeling of air conditioning and can also save energy by simply setting the room temperature in the same manner as with a conventional air conditioner. An outdoor-air treating air conditioner which controls a blowing-air temperature to be at a constant level by controlling pressure to be at a constant level and which treats outdoor air according to a set indoor enthalpy condition to supply the treated outdoor air to inside a room, wherein, if a measured room temperature value reaches a set value, a target pressure value and a target blowing-air temperature value are automatically changed to a preset target pressure value and a preset target blowing-air temperature value, respectively, the pressure and the blowing-air temperature are controlled to be at constant levels on the basis of the target pressure value and the target blowing-air temperature value, and in addition thermo-on/off control is performed according to whether or not the difference between the measured room temperature value and the set value has reached a set temperature difference.</p> |
