A ventilation fan includes a body unit, which has a fan disposed in a body case and a fan controller operable to control an air volume of the fan. The ventilation fan also includes a sensor module having an indoor environment detecting sensor and a module controller operable to control a detecting operation of the indoor environment detecting sensor. The body unit has a module mount on which the sensor module is mounted and another sensor module can be mounted in place of the sensor module. The module mount is connected to the fan controller. The module controller outputs detection information obtained based on a detection result of the indoor environment detecting sensor to the fan controller, which in turn controls the air volume of the fan based on the detection information inputted thereto.

An air conditioner is provided. The air conditioner includes a display, a storage configured to store power consumption information and time information which are required to increase or decrease an indoor temperature by a unit temperature according to an outdoor temperature, a sensor, and a processor configured to predict, based on a desired temperature being input, at least one of a power consumption or a required time for the indoor temperature to reach the desired temperature by the sensor based on information stored in the storage, and provide at least one of the predicted power consumption or the required time through the display.

A luminaire for lighting and for distribution of conditioned air within a space includes a housing having a lighting element, a duct opening, and at least one air vent coupled to the duct opening. The at least one air vent is configured to deliver conditioned air to the space. A method of controlling light and conditioned air delivery within a space, by a single combined lighting and conditioned air fixture, includes providing control and power signals to a controller coupled to the single combined lighting and conditioned air fixture, controlling lighting functions via the controller, and controlling conditioned air functions via the controller.

An environmental control system includes: a wind blower which blows wind toward a subject; and a control apparatus which performs control that makes a sympathetic nervous system of the subject dominant over a parasympathetic nervous system of the subject by changing a wind speed of the wind that is blown by the wind blower at a cycle in a range from 15 minutes to 60 minutes and by setting a time in which the wind speed is a smallest value to less than or equal to 75% of the cycle.

To provide a system that collects data from each sensor (airflow, temperature, humidity, atmospheric pressure, illuminance, and air pollution) that measures an environmental factor and can evaluate an environment in a factory in a complex manner. Environmental sensors that measure environmental elements including at least airflow from among the airflow, temperature, humidity, atmospheric pressure, illuminance, and a degree of air pollution, which are the environmental elements in a factory where a machining operation is performed, a display unit that visualizes and displays measurement results of a plurality of environmental elements measured by the environmental sensors, an evaluation and determination unit that evaluates and determines at least one of machine accuracy, work environment, and image accuracy based on the measurement results of the plurality of environmental elements, and a control unit that controls in-factory equipment so that an environment in the factory becomes a preset environment based on results of evaluation and determination by the evaluation and determination unit are included.

An environmental monitor device with a database comprises a data bus, a multitude of sensors, at least one processing unit, input/output device(s); communications interface(s), and memory. Communications interface(s) communicate with at least one environmental sensor device comprising with a multitude of sensors. The multitude of sensors may include particle counter(s), pressure sensor(s) and/or the like. The memory is configured to hold data and machine executable instructions. The machine executable instructions are configured to cause at least one processing unit to: collect sensor data from at least one environmental sensor device; store at least some of the sensor data in at least one database; and generate a report of sensor data that exceeds at least one threshold.

An HVAC register or return grille with an integrated nightlight, a battery-operated nightlight module and an area on the grille suitable for mounting the nightlight module. The nightlight module is operatively coupled to the grille and fitted with motion sensing technology to activate the light when a user nears the device. The integration of nightlight technology into HVAC grilles allows for a discrete nightlight location and enhances the utility of conventional HVAC register and return grilles.

An environment control system that controls an environment of a subject is provided. The environment control system includes an actuator configured to control an environment of a subject, and a controller configured to control an operation of the actuator. The environment control system includes an inference unit that includes a first learned model and a second learned model. The first learned model has been trained by associating environmental information indicating an environment of a subject with data correlating with one of sleep, excretion, movement, skin, and stress conditions of the subject. The second learned model has been trained by associating the data correlating with one of the sleep, excretion, movement, skin, and stress conditions of the subject with data correlating with a magnitude of one or more risks that may occur with respect to the subject in a future period of time. The environment control system includes an operating condition determining unit configured to, in a case in which data correlating with the magnitude of the one or more risks that may occur with respect to a subject in a future period of time is inferred based on the first and second learned model, evaluate the inferred data to determine an operating condition of the actuator.

An environmental control system includes: an air conditioner for adjusting a temperature in a space in which a subject is located; and a control apparatus which performs control that makes a parasympathetic nervous system of the subject dominant over a parasympathetic nervous system of the subject by performing first control and second control using the air conditioner. The first control increases the temperature in the space, and the second control cyclically changes the temperature in the space in such a manner that a temperature difference from a largest value to a smallest value in the space falls within 3 degrees Celsius.

An air conditioner system (1) runs in a concentration keeping mode to sequentially repeat a first operation of lowering a target temperature to a first target temperature lower than a predetermined reference temperature and a second operation of raising the target temperature to a second target temperature higher than the reference temperature. The target temperature is gradually raised from the first target temperature to the second target temperature in the second operation. Lowering the target temperature to the first target temperature in the first operation takes shorter time than raising the target temperature to the second target temperature in the second operation.
