The present invention relates to a method for controlling a thermoregulated ventilation circuit (100) equipped with a control unit (40) and comprising an active humidifier (10). The active humidifier (10) further comprises, in turn, a cartridge (20) equipped with a humidification chamber (21) adapted to contain water to be heated for the humidification of the air through a heating element (30), and the thermoregulated circuit (100) further comprising at least one intake tube (120) for conveying the air exiting said cartridge and provided with heating means (123) for heating the air exiting said cartridge (20). The method according to the present invention is characterised in that said control unit (40) receives in input the patient's temperature data (Tp) detected by a patient's temperature probe (132) and regulates the operation of said heating element (30) of said cartridge (20) and the operation of said heating means (123) of the air exiting said cartridge (20) as a function of said patient's temperature (Tp).

Occupant thermal comfort may be inferred and improved using body shape information. Height, weight, and shoulder circumference of an occupant of a room may be obtained using a depth sensor. A model may be utilized that is trained on a dataset including information reflecting of occupant comfort within the room versus temperature, the model receiving, as inputs, the height, the weight, and the shoulder circumference of the occupant and environmental information and outputting a comfort class. A temperature set-point for is identified which the room occupant is identified by the model as having the comfort class being indicative of user comfort. Heating, ventilation, and air conditioning (HVAC) controls are adjusted for the room to the identified temperature set-point.

Methods for controlling temperature in a conditioned enclosure such as a dwelling are described that include an “auto-away” and/or “auto-arrival” feature for detecting unexpected absences which provide opportunities for significant energy savings through automatic adjustment of the setpoint temperature. According to some preferred embodiments, when no occupancy has been detected for a minimum time interval, an “auto-away” feature triggers a changes of the state of the enclosure, and the actual operating setpoint temperature is changed to a predetermined energy-saving away-state temperature, regardless of the setpoint temperature indicated by the normal thermostat schedule. The purpose of the “auto away” feature is to avoid unnecessary heating or cooling when there are no occupants present to actually experience or enjoy the comfort settings of the schedule, thereby saving energy.

A heating, ventilation, and air conditioning (HVAC) system may be zoned into one or more zone. The HVAC system may include HVAC components, sensors, and one or more register vents that may include vent dampers (e.g., electronically controllable vent dampers or manually operated vent dampers). Opening and closing of the vent dampers may facilitate creating zones or sub-zones in the HVAC system configuration. An HVAC control system may receive a request for conditioned air in one or more of the zones, determine a damper setting for at least one of the vent dampers, communicate the determined damper setting to a vent damper or user interface, determine which HVAC components should be active, if any, and/or provide controls signals to activate or keep active the HVAC components that are determined to be active.

The present disclosure provides an air conditioner and a control method thereof. The control method of the air conditioner is capable of acquiring a voice of a user including a state of the user, transmitting the voice of the user to an external server, receiving, from the external server, a control command acquired by using a cooling tendency of the user and the state of the user determined on the basis of a usage history of the air conditioner, and controlling the air conditioner on the basis of the control command. In particular, at least a part of a method of acquiring a control command on the basis of a cooling tendency of a user may use an artificial intelligence model trained according to at least one of machine learning, a neural network, and deep learning algorithms.

Indoor personnel information identifying apparatus and method for assisting an air conditioning system of on-demand air supply are provided, the apparatus includes a data acquisition device, an information processing device and an information display device, the data acquisition device is configured to acquire weight information and shoe image information of personnel in real time, the information processing device is configured to predict an total calorific value of indoor personnel according to a real-time number of indoor personnel and obtain recommended air supply parameter information for the air conditioning system according to the total calorific value, the information display device is configured to receive and display personnel information processed by the data acquisition device and the information processing device and the recommended air supply parameter information. The apparatus can achieve an effect of reducing energy consumption under conditions of ensuring good indoor air quality and high personnel comfort.

A system includes first and second acquisition units that acquire first and second biological information of a target, and an estimation unit. The first acquisition unit includes at least one first sensor. The second acquisition unit includes at least one second sensor different from the at least one first sensor. The estimation unit estimates a thermal comfort of the target based on the first and second biological information. The estimation unit further estimates a first thermal comfort of the target based on the first biological information, and the thermal comfort of the target based on the first and second biological information. When the second acquisition unit does not acquire the second biological information, the estimation unit sets, as the thermal comfort of the target, the first thermal comfort that is corrected using previous thermal comfort of the target estimated by the estimation unit based on at least the second biological information previously acquired by the second acquisition unit.

An adaptable climate control method for controlling a thermal climate within a confined space based on thermal and/or physiological features of one or more occupants of the confined space is provided. The method includes receiving thermal images of a plurality of target areas from the occupants, identifying a plurality of interesting points of the received thermal images, and isolating the interesting points to construct thermal maps of the target areas. Thermal features of the occupants are determined using the respective thermal maps and the thermal features are used to construct thermal feature vectors for the occupants. Physiological features from physiological sensors can also be added as elements of the thermal feature vectors to form integrated vectors. The thermal feature vectors and/or integrated vectors are classified using a classifiers and at least a portion of the thermal climate of the confined space is adjusted based on the classification of the vectors.

A comfort determination device (10) includes: an acquisition unit (11A) configured to acquire time series data on a blood flow of a target; a calculator (14A) configured to calculate an index of fluctuation indicating fluctuations in the blood flow of the target from the time series data on the blood flow acquired by the acquisition unit (11A); and a determiner (14B) configured to determine whether or not the target is comfortable, based on the index of fluctuation calculated by the calculator (14A).

A signal processing system includes an expiratory information acquisition unit and a nerve recognition uni. The expiratory information acquisition unit acquires expiratory information as a piece of biometric information about a person's expiratory volume. The nerve recognition unit recognizes, based on a dispersion in the expiratory information, a condition of the person's autonomic nervous system.
