Abstract: An air-conditioning apparatus includes an indoor unit. The indoor unit includes a first panel provided in a front surface where an air outlet is provided in the indoor unit, a second panel to which a filter for an air inlet is attached, the second panel being provided in the front surface of the indoor unit, and a third panel provided in a side surface of the indoor unit. At least one of the first panel, the second panel, and the third panel is formed from a translucent member.

Abstract: Each of plurality of personal terminals is configured to acquire first data indicating a result of inputting whether a possessor is comfortable, second data indicating a terminal location, and third data indicating a temperature at the terminal location. An information processing device includes a first learning unit to classify the plurality of personal terminals into a plurality of classes based on the first to third data transmitted from the plurality of personal terminals, a storage unit to store a plurality of control details each associated with a corresponding one of the plurality of classes into which the first learning unit classifies the plurality of personal terminals, and a control unit to read, from the storage unit, a control detail associated with a class into which a personal terminal detected in an air conditioning target space is classified among the plurality of classes and control an air conditioning device.

Abstract: A model generation unit converts each of a first model, a second model, and a third model into a trained model. First training data includes a first parameter representing the degree of clogging of an air filter, a second parameter pertaining to the air-conditioning power of an air-conditioning system, and a third parameter representing an increased amount of electric power cost of the air-conditioning system due to the first parameter during operation of the second parameter. Second training data includes a fourth parameter representing a first date and time and a fifth parameter pertaining to air-conditioning power of the air-conditioning system assumed on the first date and time. Third training data includes a sixth parameter representing a second date and time and a seventh parameter representing a maintenance cost of the air filter on the second date and time.
