A voice inputting device inputs a voice operation of a user, and transmits voice data based on the voice operation to a first cloud server. The first cloud server receives the voice data from the voice inputting device, analyzes the received voice data, and determines an operational skill level of the user and the details of the voice operation. A second cloud server generates a control command for an air conditioner based on the operational skill level and the details of the voice operation determined by the first cloud server, and transmits the generated control command to the air conditioner.

Apparatus control system and apparatus control method

An air conditioning system includes: an air conditioning device, a ventilator, a sensor group, an operation terminal, and a control device installed in a building. The control device performs controlling and monitoring of operation of the air conditioning device and the ventilator. The control device controls the ventilator so as to operate during the maintenance operation of the air conditioning device.

Air-conditioning system, controller, and program

An air-conditioning ventilation system of the present invention includes one or a plurality of air circulation devices configured to circulate air among a plurality of rooms, one or a plurality of air-conditioning apparatuses provided in at least one of the plurality of rooms, a human detector provided in each of the plurality of rooms and configured to detect a human present in a corresponding one of the rooms in which the human detector is provided, an optimal air-conditioning ventilation operation estimating unit configured to estimate presence or absence of any human in each of the plurality of rooms, or a human presence ratio representing a number of humans present per unit time in each of the plurality of rooms, on a basis of a past result of detection by the human detector, and a controller configured to control the air circulation device and the air-conditioning apparatus on a basis of a result of estimation by the optimal air-conditioning ventilation operation estimating unit.

Air-conditioning ventilation system

In an air-conditioning system, during precooling or preheating control, a setting temperature is controlled such that a first temperature difference between the setting temperature and an indoor temperature is not less than a temperature difference at which a compressor performs operation, and the setting temperature is controlled to be changed to a target temperature when a second temperature difference between the indoor temperature and the target temperature is less than the first temperature difference. Since the compressor can be operated in the range from a low capacity to a medium capacity, operation efficiency of the air-conditioning apparatus can be increased, and the energy-saving operation with less power consumption can be realized. Since the operation capacity of the compressor can be readily suppressed with adjustment of the setting temperature, control is facilitated and the precooling control can be incorporated in various types of air-conditioning apparatuses.
