1. A controller configured to control operations ofa humidity control apparatus arranged and configured to perform humidity control processing of a predetermined space, the humidity control apparatus including a humidity controlling refrigerant circuit having a humidity controlling compressor, a first adsorption heat exchanger, a second adsorption heat exchanger, a humidity controlling expansion mechanism, and a switching mechanism interconnected to each other, the switching mechanism being switchable betweena first switched state allowing refrigerant discharged from the humidity controlling compressor to circulate in order through the first adsorption heat exchanger, the humidity controlling expansion mechanism, and the second adsorption heat exchanger anda second switched state allowing the refrigerant discharged from the humidity controlling compressor to circulate in order through the second adsorption heat exchanger, the humidity controlling expansion mechanism, and the first adsorption heat exchanger, andan air conditioner arranged and configured to perform air conditioning processing of the predetermined space, the air condition including an air conditioning refrigerant circuit having at least an air conditioning compressor, a heat source-side heat exchanger, a utilization-side heat exchanger, and an air conditioning expansion mechanism interconnected to each other,the controller comprising:

  • a power consumption detector arranged and configured to detect power consumption of the humidity control apparatus and the air conditioner;

    a target value setting processor configured to perform one ofa first processing lowering a target operating frequency of the humidity controlling compressor and lowering a target evaporation temperature in the utilization-side heat exchanger, anda second processing raising the target operating frequency and raising the target evaporation temperature,in order to perform optimal target value setting processing in which the target operating frequency and the target evaporation temperature are set so as to minimize the power consumption; and

    an operation control unit configured to controlthe humidity controlling compressor to achieve the target operating frequency andat least one of the air conditioning compressor and the air conditioning expansion mechanism to achieve the target evaporation temperature.
