    摘要： An air-conditioning apparatus includes a heat-exchange unit. The heat-exchange unit has a pair of heat exchangers, and a partition plate disposed in such a state that a first region located on the inside of a space between the pair of heat exchangers and a second region located on the outside of the space are formed. The heat-exchange unit is disposed in such an orientation that one of the pair of heat exchangers is provided adjacent to and above the other heat exchanger and that the second region of the partition plate is located on the downstream side of the first region. The second region of the partition plate is provided with an inlet of a drain path.

    摘要： An air-conditioning system includes two or more air-conditioning devices A, each of which in turn includes a fan adapted to adjust a volume of air blown out into a space to be air-conditioned, an airflow direction adjuster adapted to adjust an airflow direction of outlet air blown out by the fan, a human detection sensor adapted to detect human presence, an inlet air temperature sensor adapted to detect temperature of inlet air sucked in by the fan, a position setting device used to set an installation location of each of the air-conditioning devices, and a controller, in which a positional relationship with an adjacent air-conditioning device is calculated based on data from the position setting device and furthermore a human detection area overlap with the adjacent air-conditioning device is calculated.

    摘要： An active filter device includes a power module configured to generate a compensating current to suppress a harmonic current generated from a load device and a controller configured to control the power module. The controller includes a current command calculation unit configured to calculate a compensating current command to suppress the harmonic current, a control variable calculation unit configured to calculate a control variable based on a deviation between the compensating current command and an actual compensating current, a duty cycle calculation unit configured to calculate duty cycle of each of three phases based on the control variable, a duty cycle modulation unit configured to perform two-phase modulation on the duty cycle of each of three phases, and a control signal generation unit configured to, after the two-phase modulation, generate, from the duty cycle of each of three phases, a control signal to drive the power module.
