Air conditioning operating device and air conditioning operating method

An air conditioning operating device in an air conditioning system using both a heat exchange type air conditioner and an outdoor air cooler, the air conditioning operating device comprising:

• an outdoor air temperature information acquisition device acquiring outdoor air temperature measurement values;
• a room temperature information acquisition device acquiring room temperature measurement values;
• an air conditioner state information acquisition device acquiring information about a state of a heat exchange type air conditioner and a state of the outdoor air cooler;
• calculator calculating an estimated value for room temperature during outdoor air cooling and calculating the estimated value for room temperature after switching to a complete outdoor air cooling mode that stops the heat exchange type air conditioner, from a cooling mode mainly using the heat exchange type air conditioner that carries out room temperature control mainly by increasing or decreasing an effect of the heat exchange type air conditioner, and carries out the room temperature control only by increasing or decreasing an effect of the outdoor air cooler, based on a measured value for outdoor air temperature, a measured value for room temperature, information about the state of the heat exchange type air conditioner and information about the state of the outdoor air cooler;
• a display displaying the estimated value for room temperature during outdoor air cooling such that an occupant may recognize the estimated value for room temperature;
• and
• a switch switching to the complete outdoor air cooling mode according to results of a determination of whether switching is possible or not based on one or more conditions the occupant has set or switching indicating input by the occupant.
