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

An air-conditioning unit control device that controls an air-conditioning unit system including one or more outdoor units and a plurality of indoor units connected to the outdoor units by pipes, the indoor units being configured to condition air in a space, the air-conditioning unit control device comprising:

• an environment target value setting unit configured 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 configured to form one or more groups of the indoor units and set a zone for each of the groups or change the zone based on a difference between the environment target value and an environment-condition-related value detected by indoor environment condition detecting unit in an installation position for each of the indoor units, the zone serving as a subspace;
• a zone load calculating unit configured to calculate a heat load on the zone set or changed by the zone setting unit;
• an air conditioning capacity allocation calculating unit configured to calculate and 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 so as to minimize the total power consumption;
• a control instructing unit configured to transmit a control signal based on the operation capacity of each of the indoor units and the outdoor units calculated by the air conditioning capacity allocation calculating unit to each of the indoor units and the outdoor units;
• and
• an environment status input unit configured to input data representing qualitative information which is an environment-status-related value,
• wherein the environment target value setting unit changes the environment target value based on each environment-condition-related value and the environment-status-related value.
