Abstract: An operation data acquisition unit acquires from an air conditioning system, operation data of the air conditioning system. A model application determination unit determines whether or not the operation data satisfies an application condition for applying the operation data to an inference model for inferring status of the air conditioning system. Further, the model application determination unit stores the operation data into an operation data holding unit as pending operation data, when the operation data does not satisfy the application condition. A model updating unit determines whether or not the pending operation data is operation data suitable for an update of the inference model, and updates the inference model using the pending operation data, when it is determined that the pending operation data is the operation data suitable for the update of the inference model.

Abstract: A ventilation information display apparatus includes functions of a ventilation information acquisition unit and a display unit. The ventilation information acquisition unit acquires required ventilation information indicating a required amount of ventilation, which is an amount of ventilation required in a target space and actual ventilation information indicating an actual amount of ventilation, which is an amount of ventilation of a ventilator installed in the target space. The display unit displays the required amount of ventilation indicated in the required ventilation information and the actual amount of ventilation indicated in the actual ventilation information that are acquired by the ventilation information acquisition unit.

Abstract: The learning device includes: a first data acquisition unit; and a model generation unit. The first data acquisition unit is configured to acquire operation data of an air conditioning system. The model generation unit is configured to convert a specific model into a trained model using the operation data. The operation data includes a specific parameter and at least one of a temperature of air passing through the second heat exchanger, a temperature and a pressure of refrigerant, and a temperature outside a space where each of at least one indoor unit is arranged. The specific model estimates the specific parameter from the operation data other than the specific parameter. The specific parameter includes at least one of an operating frequency of the compressor, a degree of opening of the expansion valve, and an amount of air blown per unit time by the blower.

Abstract: A first power consumption estimation unit estimates as a first power consumption, a power consumption generated in a first operation mode in which operation of an air conditioner is suspended at a timing when a room equipped with the air conditioner turns not to be used and the operation of the air conditioner is resumed so that a temperature of the room reaches a preset temperature at a timing when the room turns to be used. A second power consumption estimation unit estimates as a second power consumption, a power consumption generated in a second operation mode in which the operation of the air conditioner is continued even while the room is not being used. A determination unit compares the first power consumption with the second to determine whether to suspend or continue the operation of the air conditioner at the timing when the room turns not to be used.

Abstract: An information processing apparatus includes a memory storing equipment information, an equipment characteristics table, and an energy saving control menu, a receiver configured to receive energy saving control and a condition and acquire operation data and measurement data from a controller of equipment, a processor, and a display outputting a result. The processor obtains an actual load factor based on the operation data and the measurement data, obtains a control characteristics correction parameter regarding control characteristics of the equipment, estimates a load factor distribution for an estimation target period according to the actual load factor.

Abstract: A control apparatus (40) controls an air conditioning system including: an internal conditioning machine which takes in air from inside of a target space, adjusts temperature of the air, and then outputs the air to the target space; and an external conditioning machine which takes in air from outside of the target space, adjusts temperature of the air, and then outputs the air to the target space. A setting unit (411) receives input of information regarding comfortability in the target space, and sets a target value for the comfortability. A controlling unit (413) controls both the internal conditioning machine and the external conditioning machine based on the target value set by the setting unit (411).
