US Patent 9383736 Air-conditioning controlling device and method

An air-conditioning controlling device includes an indicator calculating portion that calculates one or more indicators for evaluating, for each individual Pareto solution, similarity of the detail of air-conditioning control based on the operating volumes and/or the state distributions for the Pareto solution, a similarity calculating portion that calculates, for each Pareto solution, similarity of the Pareto solution to a reference Pareto solution, based on the indicators for the Pareto solution and the indicators for the reference Pareto solution, which is selected as a reference from the Pareto solutions, and an air-conditioning instructing portion that sends, to the air-conditioning system, the operating volumes of the Pareto solution with the least similarity to the reference Pareto solution from among the Pareto solutions belonging to the new air-conditioning controlling mode when there is a change, to a new air-conditioning controlling mode, of the air-conditioning controlling mode that is applied to the air-conditioned space.
