A centrifugal air-sending device has blades that each have a vane length in a first region that is greater than a vane length in a second region, and are each formed such that a proportion for which a turbo vane portion accounts is higher in a radial direction than a proportion for which a sirocco vane portion accounts in the first region and the second region. The blades that are located closer to an outer circumference than is a blade inner diameter of inner circumferential ends of the blades at end portions of the blades that are close to a side plate in an axial direction are defined as a blade outer circumferential portion that is formed such that a vane thickness of each of the blades in decreased in the radial direction from an inner circumference toward the outer circumference.

A weighing and pricing device includes: a processor that executes a registration process for a product to be purchased by a customer; a transceiver that: establishes a connection between a mobile device possessed by the customer and the weighing and pricing device; and upon establishing the connection, receives, from the mobile device, identification information that identifies the mobile device; and a storage that stores information relating to the product and the identification information in association with each other. After the registration process is interrupted, the transceiver receives, from the mobile device, identification information. The processor specifies the product associated with the stored identification information that corresponds to the identification information received after the registration process. The processor recommences the registration process for the specified product.

An air-conditioning apparatus includes: a centrifugal air-sending device including a fan and a scroll casing having a tongue portion and a discharge portion, and a housing having a housing suction port and a discharge portion. A trailing edge of a blade located closest to a wall portion of the housing is a first trailing edge portion, and a leading edge of a blade located closest to the tongue portion is a first leading edge portion. In a first region, a boundary portion located closest to the tongue portion is located between first and second straight lines. The first straight line passes through a rotation axis of the fan and the first trailing edge portion, the second straight line is parallel to the first straight line and passes through the first leading edge portion, and the first region forms part of the housing suction port close to the tongue portion.

An air-conditioning apparatus performs air conditioning by causing heat exchange between refrigerant cycling through a refrigerant circuit and indoor and outdoor air. The air-conditioning apparatus includes a sensor and a control determination device. The sensor measures concentration of any of the refrigerant leaked into the air. The control determination unit determines leakage of the refrigerant in a case when the concentration of any refrigerant leaked into the air is greater than a first threshold. The control determination device further determines an abnormality in the sensor in any one of a case where a cumulative time period of determined leakages is greater than a predetermined time period, a case where a cumulative number of times of determined leakages is greater than a predetermined number, and a case where the value indicating the concentration of any refrigerant leaked into the air is greater than a higher second threshold.

An air-conditioning apparatus includes an indoor unit and an outdoor unit connected to each other via a refrigerant pipe through which refrigerant flows. The air-conditioning apparatus includes a refrigerant sensor that detects leakage of the refrigerant in the indoor unit, a notification unit that provides a notification of occurrence of leakage of the refrigerant, a transmitter that communicates with an external terminal via a network, and a controller that controls the notification unit and the transmitter. The notification unit includes a display and a speaker disposed on a surface of a casing of the indoor unit, and the external terminal. When leakage of the refrigerant is detected by the refrigerant sensor, the controller controls the notification unit and the transmitter to provide a notification of occurrence of leakage of the refrigerant.

A mobile terminal includes: a processor that acquires a type of a product sold by weight; and a transceiver connected to the processor and that establishes intercommunication with a weighing device that weighs the product sold by weight; a storage connected to the processor. The processor causes the transceiver to acquire, from the weighing device, a weight value of the product sold by weight weighed by the weighing device. The processor registers, in the storage, the type of the product and the weight value that corresponds to the type of the product.

A rotation calculation unit calculates a rotation speed of a virtual generator on the basis of a rotor model to simulate driving of the virtual generator and calculates the rotation speed of the virtual generator. A target power determination unit determines target values of active power and reactive power of an inverter on the basis of the calculated rotation speed. A command generation unit generates a control command for the inverter on the basis of the determined target values of the active power and the reactive power.

In an air-conditioning apparatus, an indoor unit and an outdoor unit are connected to each other by a refrigerant pipe through which refrigerant flows. The air-conditioning apparatus includes: a refrigerant detection unit that detects a leak of the refrigerant in the indoor unit; a notification unit that makes a notification indicating occurrence of the leak of the refrigerant; a controller that controls at least the notification unit; and a remote control unit configured to operate the indoor unit. When the refrigerant detection unit detects the leak of the refrigerant, the controller controls the notification unit to make in a first mode the notification indicating the occurrence of the leak of the refrigerant, and make the notification in a second mode different from the first mode after a predetermined time period elapses from time at which the notification in the first mode is made. Thus, since the notification of the refrigerant leak is made two steps, that is, in the first mode in a first step and in the second mode in a second step, it is possible to cause a user to pay more attention to the notifications, and thus cause the user to easily notice the notification. It is therefore possible to cause the user to sufficiently know the refrigerant leak.

The refrigerant leakage determination device includes a refrigerant detection sensor that detects presence of gas and transmits a concentration of the gas as a sensor output, an alarm device that issues an alarm about leakage of refrigerant, and a controller configured to control the alarm device based on the sensor output from the refrigerant detection sensor. The controller includes a storage device that stores two thresholds for the sensor output and two set times each having a length set for each threshold, and a processing device that, when the sensor output exceeds one or both of the two thresholds and a length of a time period during which the sensor output exceeds the one or both of the two thresholds is longer than either one of the two set times associated with the two thresholds, determines leakage of refrigerant and actuates the alarm device.

An air-conditioning apparatus includes a refrigerant circuit in which refrigerant is circulated, and an indoor unit configured to accommodate a load-side heat exchanger of the refrigerant circuit. The indoor unit includes an air outlet provided in the housing, an air inlet provided in the housing below the air outlet, an air passage that extends between the air inlet and the air outlet via the load-side heat exchanger, a refrigerant detection unit disposed below the air inlet, and a first partition plate configured to separate the air passage from a space in which the refrigerant detection unit is installed.
