  • Publication number: 20210222905
    Abstract: In an air-conditioning device, an air-conditioning unit for air-conditioning a target space includes a compressor to compress a refrigerant and circulates the refrigerant through a refrigerant pipe, a heat exchanger to cause heat exchange between air in the target space and the refrigerant circulating through the refrigerant pipe, and a blower to feed air in the target space to the heat exchanger. An acquirer acquires a temperature and a humidity in the target space. An air-conditioning controller switches an operation mode in accordance with the temperature and the humidity acquired by the acquirer between a cooling mode in which the air-conditioning unit cools the target space, a dehumidification mode in which the air-conditioning unit dehumidifies the target space, and an air-blowing mode in which the compressor is stopped without the blower stopping air blowing.

  • Publication number: 20200412570
    Abstract: 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.

  • Patent number: 10208976
    Abstract: 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.

  • Patent number: 10060643
    Abstract: 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.
