Air-conditioning management device and air-conditioning system using the same

An air-conditioning management device configured to manage power consumption amounts of one or a plurality of air-conditioning apparatuses performing air-conditioning in a plurality of air-conditioned areas, the air-conditioning management device comprising:

• a power consumption obtaining unit configured to obtain an overall power consumption amount of the one or plurality of air-conditioning apparatuses in their entirety in one day and individual power consumption amounts of the respective plurality of air-conditioned areas;
• an overall excess coefficient calculation unit configured to calculate an overall excess coefficient from the overall power consumption amount in one day obtained by the power consumption obtaining unit and an overall target value set on a monthly basis, the overall excess coefficient indicating a degree of excess from the overall target value on the monthly basis;
• an individual excess coefficient calculation unit configured to calculate individual excess coefficients from the individual power consumption amounts in one day obtained by the power consumption obtaining unit and individual target values set on a monthly basis, the individual excess coefficients each indicating a degree of excess from the individual target value on the monthly basis;
• an excess determination unit configured to determine whether or not the overall excess coefficient calculated in the overall excess coefficient calculation unit is larger than a set threshold value;
• an energy saving control setting unit configured to set energy saving control conditions for the respective plurality of air-conditioned areas to provide increased energy saving effects in descending order of the individual excess coefficients calculated in the individual excess coefficient calculation unit when the overall excess coefficient is determined, in the excess determination unit, to be larger than the set threshold value;
• and
• an operation control unit configured to perform energy saving operation of the air-conditioning apparatuses based on the energy saving control conditions set in the energy saving control setting unit.
