Abstract: The indoor unit has an air passage formed therein to allow the indoor air drawn in the indoor unit to pass therethrough. The first indoor heat exchanger, the adsorption and desorption device, and the second indoor heat exchanger are arranged in the air passage. The second indoor heat exchanger is disposed downstream of the first indoor heat exchanger, and the adsorption and desorption device is disposed downstream of the first indoor heat exchanger and upstream of the second indoor heat exchanger. To perform dehumidifying control, the controller controls the opening degree of the first expansion valve and the second expansion valve to enable switching between cooling adsorption mode where the adsorption and desorption device adsorbs moisture in the indoor air and cooling desorption mode where the adsorption and desorption device desorbs the adsorbed moisture.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a network of wireless remote climate sensors to develop a complete heat map of an enclosed space. The remote climate sensor is configured to collect temperature and humidity data on a zone of the enclosed space. The HVAC system uses a network of these sensors to obtain data points across the enclosed space. The resulting heat map is used by the HVAC system to determine where to direct air in the enclosed space. By comparing the temperature and humidity at a specific remote climate sensor with the user's desired temperature and humidity, the HVAC system can decide whether to increase or decrease the air flow through a variable damper that is located near the remote climate sensor. By conducting this analysis throughout the enclosed space and making incremental adjustments to the air flow in hot and cold spots in the enclosed space, the disclosed HVAC system provides even comfort to the user along with reduced energy consumption.

Abstract: During a sleep session of a user of a display assistant device, the device records sound, movement, and ambient conditions in proximity to the device. The ambient conditions include a light level. The device analyzes the recorded sound and movement to identify throughout the sleep session of the user a time-varying sleep state of the user. The sleep state is characterized by a sleep quality and a sleep phase. The device also analyzes the recorded ambient conditions and the recorded sound throughout the sleep session to identify a plurality of time-varying sleep disturbances occurring during the sleep session of the user. After the sleep session of the user has concluded, the device presents on a screen of the device a sleep summary of the sleep session. The sleep summary includes visual indications of the sleep quality and disturbances identified throughout the sleep session.

Abstract: A network of wireless remote climate sensors in a heating, ventilation, and air conditioning (HVAC) system permits the creation of personalized microclimates within an enclosed space. In addition to collecting temperature and humidity data, the wireless remote climate sensors can detect whether the enclosed space is occupied by a human. Human detection is made possible by optional cameras, microphones, and gas sensors on the wireless remote climate sensors. As the human moves throughout the enclosed space, the HVAC system is able to track the human's movement using the wireless remote climate sensors. The HVAC system may adjust airflow to different portions of the enclosed space based on the human's location. The result is an efficient use of system resources to keep users at their ideal temperature.

Abstract: Controlling heating and cooling in a conditioned space utilizes a fluid circulating in a thermally conductive structure in fluid connection with a hydronic-to-air heat exchanger and a ground heat exchanger. Air is moved past the hydronic-to-air heat exchanger, the air having fresh air supply and stale air exhaust. Sensors located throughout the conditioned space send data to a controller. User input to the controller sets the desired set point temperature and humidity. Based upon the set point temperature and humidity and sensor data, the controller sends signals to various devices to manipulate the flow of the fluid and the air in order to achieve the desired set point temperature and humidity in the conditioned space. The temperature of the fluid is kept less than the dew point at the hydronic-to-air heat exchanger and the temperature of the fluid is kept greater than the dew point at the thermally conductive structure.

Abstract: A system and method for minimizing indoor infection risk and improving indoor air quality (IAQ) while maximizing energy savings. The system integrates occupancy detection and forecasting, outdoor weather conditions and forecasting, indoor infection risks and air quality modeling, any tunable air filtration, the clean air delivery rate, and any portable air cleaners. The system outputs the total amount of outdoor air intake, the air temperature of the supply air into the space, the supply air flow rate into the space, the operation mode of tunable air filtration/purification/disinfection, the operation mode of the in-room air cleaner, and space/room temperature set-points, and thus can serve as the central controller for an HVAC system.
