Abstract:
The instruction device according to the present invention is used in an air conditioning system. In a case where evaluation information concerning comfort of an air environment of an indoor space for person(s) in the indoor space corresponds to discomfort and a difference between first data on the air environment of the indoor space and second data on an air environment of an outdoor space is not less than a prescribed value, the instruction device creates setting information to use only a first air conditioning device for causing movement of air between the indoor and outdoor spaces when determining that the comfort can be improved by the first air conditioning device, and creates setting information to use a second air conditioning device for controlling the air environment of the indoor space by consuming energy resource when determining that the comfort cannot be improved by the first air conditioning device.
Abstract:
An airflow control system includes a first outlet member, a second outlet member, a flow velocity adjustment system, a supply system, and a controller. The second outlet member surrounds the first outlet member. The flow velocity adjustment system may adjust a flow velocity of a first airflow flowing through an internal space of the first outlet member toward a first outlet vent and a flow velocity of a second airflow flowing through a space between the second outlet member and the first outlet member toward a second outlet vent. The supply system may supply a functional component to be diffused in the air to at least one of the first airflow or the second airflow. The controller controls at least one of the flow velocity adjustment system or the supply system.
Abstract:
A ventilation control device is a device for setting a ventilation path in an object space of wind flowing in/out through a plurality of openings between the object space and the outside of the building. The plurality of openings is disposed in a building. An air conditioner performs air-conditioning in the building. The ventilation control device includes: a ventilation-path setting unit; and an output unit. The ventilation-path setting unit sets the ventilation path so that a ventilation path in the object space, in a state in which the air conditioner operates, differs from a path of wind sent from the air conditioner. The output unit outputs path information indicating the ventilation path set by the ventilation-path setting unit.
Abstract:
An airflow control system includes an air blower, a supplier, a lighting fixture, and a controller. The air blower has an outlet port, from which an airflow with directivity is allowed to blow out. The supplier may supply the airflow blowing out from the outlet port with a functional component to be eventually emitted into the air. The lighting fixture may emit light having directivity in a direction aligned with a direction in which the airflow blows out from the outlet port of the air blower. The controller controls the air blower and the lighting fixture.
Abstract:
An air conditioning management device is configured to manage air-conditioning in a building. The air conditioning management device includes a storage unit, a selecting unit, and an execution unit. The storage unit is configured to store a first control content and a second control content. The first control content corresponds to a first scene in which no person is active in a specific space inside the building. The second control content corresponds to a second scene in which a person is active in the specific space. The execution unit is configured to execute an operational mode of operating the air conditioning adjustment system according to the first control content when the first scene is selected. The execution unit is configured to execute a notification mode of making a notification unit such as a display device report the second control content when the second scene is selected.
Abstract:
In an airflow control system, a tube body includes an inflow port and an outflow port. A first rectifying device is located between a fan and the outflow port in an axial direction of the fan and is configured to redirect an airflow which is swirling. A second rectifying device is located between the first rectifying device and the outflow port in the axial direction and is configured to align the direction of the airflow with a direction along the axial direction. The first rectifying device includes a tube part which is cylindrical and fins. Each of the fins has an arc shape. The fins protrude from an inner circumferential surface of the tube part toward a central axis of the tube part and are aligned in a direction along an inner circumference of the tube part. The second rectifying device includes flow paths along the axial direction.
Abstract:
An air blower includes a body, a fan, a rectifier unit, and an imparter. The body has a first inlet port, an outlet port, and a flow channel. The rectifier unit is disposed between a fan and the outlet port in a direction. The rectifier unit has a second inlet port. The rectifier unit divides an airflow into a first airflow and a second airflow. The first airflow has a flow velocity equal to or greater than a predetermined value. The second airflow has a flow velocity less than the predetermined value. The imparter imparts the functional component to the airflow within a range defined by projecting the first region in the direction and extending from the second inlet port through the outlet port.
Abstract:
A power conversion control device controls a power converter. The power converter converts AC power into DC power. The power conversion control device includes a hardware processor coupled to a memory. The processor performs overcurrent protection by which operation of the power converter is suspended. The overcurrent protection is performed when an amount of output current of the power converter is equal to or greater than a threshold value. The processor permits restart of operation of the power converter having been suspended by the overcurrent protection. The restart is permitted only when the overcurrent protection is performed due to decrease in output voltage of the power converter. The processor restarts operation of the power converter after the restart of operation of the power converter is permitted.
Abstract:
In a ventilation control device, a ventilation-path setting unit is configured to set a ventilation path based on environmental information acquired by an information acquisition unit. A ventilation-quantity setting unit is configured to set a ventilation quantity based on the environmental information and the ventilation path. The ventilation-path setting unit sets a plurality of candidate paths having priorities in descending order of expected ventilation effects. In the case where a first candidate path having the highest priority is identical with a previously set ventilation path, the ventilation-path setting unit sets the first candidate path as the ventilation path, when a difference value between a room temperature previously acquired and a room temperature presently acquired is equal to or more than a threshold. The ventilation-path setting unit sets, as the ventilation path, a second candidate path having the second highest priority, when the difference value is less than the threshold.
Abstract:
The air-conditioning system includes: an opening/closing device opening and closing an openable portion in an opening of a building; an air-conditioning device performing air-conditioning inside the building by consuming energy for operation; a monitoring device monitoring environmental information regarding the inside and outside of the building; and a controller controlling the opening/closing device and the air-conditioning device based on the environmental information from the monitoring device, date and time information representing a current date and time, building information representing a location condition of the building, and draft information determined by parameters including an opening area and an opening shape in the openable portion. The controller opens the openable portion and stops the air-conditioning device when the outside is more favorable in air environment than the inside, and closes the openable portion and starts the air-conditioning device when the inside is more favorable in air environment than the outside.
