<P>PROBLEM TO BE SOLVED: To achieve further energy saving by suppressing energy consumed by an air conditioning device when there is a small number of people in a space. <P>SOLUTION: According to the number of visitors in a shop obtained by a visitor number calculating device 9, a control device 10 determines a preset temperature of the air conditioning device 1. The control device 10 defines a range of the preset temperature of the air conditioning device 1 according to cooling or heating. When the number of visitors obtained by the visitor number calculating device 9 is smaller than a predetermined number, the control device 10 uses an upper-limit temperature in the range of a preset temperature as the preset temperature upon cooling and uses a lower-limit temperature in the range of the preset temperature as the preset temperature upon heating. <P>COPYRIGHT: (C)2012,JPO&INPIT |
