  • Patent number: 11293655
    Abstract: An air-conditioning apparatus includes an air-to-air heat exchanger that transfers at least sensible heat between outdoor air and indoor air, an air-to-refrigerant heat exchanger provided in an air supply passage to transfer heat between the outdoor air and refrigerant, and a humidifier provided in part of the air supply passage that is located downstream of the air-to-refrigerant heat exchange. The humidifier humidifies the outdoor air. A communication passage causes part of the air exhaust passage that is located upstream of the air-to-air heat exchanger and part of the air supply passage that is located downstream of the air-to-air heat exchanger to communicate with each other. An opening/closing damper opens and closes the communication passage. A controller controls a refrigerant temperature in the air-to-refrigerant heat exchanger based on an indoor temperature, and controls operation of the opening/closing damper based on an indoor humidity.

  • Patent number: 11262092
    Abstract: When a humidity condition, including a humidity detected by a temperature and humidity sensor and a humidification load sensing unit falling below a threshold value, is met, an outside air conditioner supplies the heated and humidified air into the room. When the humidity condition is met during the indoor heating operation, the indoor heating operation is stopped or weakened. When the humidity condition is met, only the outside air conditioner is subjected to a heating and humidifying operation. Since the indoor air is not heated by the inside air conditioner more than necessary, when a heating load is low and a humidification load is present, a “conflicting state” can be prevented in which the inside air conditioner is subjected to a cooling and dehumidifying operation and the outside air conditioner is subjected to the heating and humidifying operation.

  • Publication number: 20210374309
    Abstract: A model generating part generates an analysis model for an airflow analysis of an indoor space. A temperature distribution estimating part performs the airflow analysis of the indoor space by using the analysis model and estimates a temperature distribution in the indoor space. A communication part acquires a temperature measured at a measurement point in the indoor space. A model correcting part collates the temperature distribution estimated by the temperature distribution estimating part with the temperature at the measurement point acquired by the communication part, and corrects the analysis model based on a collation result.

  • Patent number: 11181285
    Abstract: A control unit determines, on the basis of a temperature and humidity detected by sensors, whether outdoor air cooling that takes outdoor air into a room is effective. Upon determination that the outdoor air cooling is effective, the control unit opens a damper and causes stoppage of an air supply fan disposed in an air supply path. Due to such operation, indoor air passing through an air discharge path bypasses a total heat exchanger by passing through a bypass air path, and thereby is discharged to the outdoors as exhaust air. However, due to stoppage of the air supply fan, although the outdoor air does not flow through the air supply path, the outdoor air flows into a building from an opening of the building.

  • Patent number: 11131476
    Abstract: In an air conditioning system, a cooling tower cools cooling water. A chiller generates cold water using the cooling water cooled by the cooling tower. A cooling water circulation passage circulates cooling water between the cooling tower and chiller. A first heat exchanger exchanges heat between air and the cold water generated by the chiller. A cold water circulation passage circulates the cold water between the chiller and first heat exchanger. A second heat exchanger exchanges heat between a portion of the cooling water cooled by the cooling tower and air heat-exchanged with the cold water. A cooling water branch passage, branching from the cooling water circulation passage, introduces to the second heat exchanger the portion of the cooling water introduced to the chiller from the cooling tower, and introduces to the cooling water circulation passage the portion of the cooling water heat-exchanged with air by the second heat exchanger.
