An environmental equipment control apparatus controls environmental equipment. The environmental equipment control apparatus includes a grasping unit that grasps physical-and-mental-state information about a physical and mental state of a user, and a control unit that changes a control state of the environmental equipment in a case in which the physical-and-mental-state information satisfies a predetermined state condition.

An air handling system includes a housing, a blower, a sensor, an air intake valve, and a controller. The housing includes an outlet to a passenger compartment, a fresh air inlet providing fresh air into the housing and a recirculated air inlet that guides air flow from the passenger compartment into the housing. The blower moves air through the housing. The air intake valve moves between a closed position blocking air flow from the fresh air inlet into the housing and an open position unblocking air flow from the fresh air inlet into the housing. The controller positions the air intake valve relative to the fresh air inlet controlling the flow of fresh air into the housing and thereby maintaining moisture density of the air flow entering the passenger compartment within a prescribed range based on humidity and temperature values from the sensor.

An environmental control system includes: a wind blower which blows wind toward a subject; and a control apparatus which switches between first control and second control at a predetermined timing. The first control 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 predetermined cycle, and the second control makes the parasympathetic nervous system of the subject dominant over the sympathetic nervous system of the subject by decreasing a wind speed of the wind that is blown by the wind blower to a wind speed lower than the wind speed in the first control.

A zoning system for a heating, ventilation, and/or air conditioning (HVAC) system includes a temperature control device configured to monitor a temperature in a zone of a structure for conditioning by the HVAC system and configured to send a wireless control signal including data based on the temperature, and a damper actuator configured to be associated with the zone and configured to adjust a position of a damper to control an airflow into the zone, where the damper actuator is configured to receive the wireless control signal from the temperature control device and configured to adjust the position of the damper based on the data.

An air-conditioner indoor unit is configured to be capable of changing the direction of an airflow that is blown out through a blow-out port. The air-conditioner indoor unit includes a control unit that switches between a normal mode and a wide mode. The control unit extends at least vertically a range that is to be reached by the airflow in an air-conditioning target space in the wide mode compared with the normal mode and causes the air conditioning capacity of the wide mode to be lower than the air conditioning capacity of the normal mode.

An air-conditioner indoor unit (10) is configured to be capable of changing the direction of an airflow that is blown out through a blow-out port (15). The air-conditioner indoor unit (10) includes a control unit (40) that switches between a normal mode and a wide mode. The control unit (40) switches to the wide mode when an air conditioning load is higher than a predetermined value and extends at least vertically a range that is to be reached by the airflow in an air-conditioning target space in the wide mode compared with the normal mode.
