A load processing balance setting apparatus includes first and second air-conditioners for targeted first and second areas, a calculating unit, a determining unit and an adjusting unit. The first area is included within the second area. The calculating unit calculates a sum of an air-conditioning load for the first and second air-conditioners. Preferably, the determining unit determines a first and second processing throughputs for the first and second air-conditioners so that a COP (Coefficient of Performance) for the sum of the air-conditioning loads calculated by the calculating unit is maximized or is equal to or greater than a predetermined level, or so that a power consumption level for the sum of the air-conditioning loads calculated by the calculating unit is minimized or is equal to or less than a predetermined level. The adjusting unit controls the first and second air-conditioners based on the first and second processing throughputs.
