An air-conditioning unit control device controls an air-conditioning unit system including one or more outdoor units and a plurality of indoor units. The air-conditioning unit control device includes an environment target value setting unit to set an environment target value for an environment intended to be achieved by air conditioning through each of the indoor units, a zone setting unit to form one or more groups of the indoor units and set a zone for each of the groups, a zone load calculating unit to calculate a heat load on the set zone, an air conditioning capacity allocation calculating unit to determine an allocation of operation capacity to each of the indoor units and the outdoor units based on power consumption of each of the indoor units and the outdoor units, and a control instructing unit to transmit a control signal based on each operation capacity.

Air-conditioning unit control device and air-conditioning unit control program for minimizing power consumption

A vehicle air conditioning control device calculates, through a thermal load calculating unit, a vehicle interior thermal load Q on the basis of, for example, a vehicle interior temperature Tin, a vehicle interior humidity Hin, a vehicle exterior temperature Tout, a passenger load factor &#x3b8;, and a vehicle-interior-temperature set value Tset. Through an air conditioning output calculating unit, the vehicle air conditioning control device calculates an output command value for an air conditioner on the basis of a vehicle-interior-temperature upper-limit value Tmax, a vehicle-interior-temperature lower-limit value Tmin, the thermal load Q, power-running/regenerative electric power P, and then, corrects the calculated output command value for the air conditioner on the basis of power-running/regenerative electric power Pf at or after a prediction time point and of a passenger load factor &#x3b8;f at or after the prediction time point.
