Abrégé

A motor drive apparatus includes a motor, a power converter, and a controller that controls the voltage supplied to the motor by the power converter. The power converter converts a voltage of a 400 V-class AC power supply to a voltage with an effective value lower than an effective value of the 400 V-class AC power supply. The power converter converts the voltage by a switching operation of a plurality of switching elements. The motor is configured so that a value of φ×Vx/Ld is greater than Pmax when an effective value voltage Vx=200 V. A d-axis inductance of the motor is Ld. A flux linkage of the motor is φ. A maximum output of the motor in a device where the motor is mounted is Pmax. The controller has a control mode in which an effective value voltage higher than Vx is applied to the motor.

Abrégé

An inverter control method is a method for controlling an inverter that outputs an application voltage, which is a voltage to be applied to a motor that drives a load by using rotation of a shaft. The method includes: causing the inverter to output the application voltage having an amplitude smaller than a first maximum and causing the motor to rotate at a first speed and drive the load which is predetermined; and causing the inverter to output the application voltage having an amplitude of a second maximum and causing the motor to rotate at a second speed and drive the predetermined load. The first maximum is a possible maximum value of an amplitude of the application voltage when the motor drives the predetermined load at the first speed. The first speed is a maximum of a speed of rotation of the motor when the motor drives the predetermined load. The second maximum is a possible maximum value of the amplitude of the application voltage when the motor drives the predetermined load at the second speed. The second speed is lower than the first speed.

Abrégé

Provided is a measure against a refrigerant leak. A heat load processing system includes: a heat exchanger unit including a heat exchanger; a refrigerant leak detector; and a controller that controls an operation of a ventilator. The heat exchanger is connected to a refrigerant pipe through which a refrigerant flows and a heat medium pipe through which a heat medium flows, and configured to cause the refrigerant and the heat medium to exchange heat with each other. The refrigerant leak detector detects a refrigerant leak in the heat exchanger unit. The ventilator ventilates in a facility device room where the heat exchanger unit is installed. When a refrigerant leak is detected by the refrigerant leak detector, the controller executes a process (a refrigerant leak third control) of increasing a ventilation air volume of the ventilator.

A refrigeration cycle apparatus is caused to be in a normally operable state in accordance with the mixture ratio of difluoromethane occupying a refrigerant charged in the refrigeration cycle apparatus. A refrigeration cycle apparatus includes a refrigerant circuit including a compressor and performs a refrigeration cycle by circulating a refrigerant in the refrigerant circuit with the compressor. A heat-source-side controller judges the mixture ratio of difluoromethane occupying the refrigerant charged in the refrigerant circuit. The heat-source-side controller further performs control relating to the refrigeration cycle on the basis of the mixture ratio of difluoromethane judged by the judgement unit. The controller judges the mixture ratio of difluoromethane on the basis of a discharge temperature of the refrigerant of the compressor in operation under a prescribed condition or judges the mixture ratio of difluoromethane on the basis of weights of a plurality of types of refrigerants to be charged to the refrigerant circuit.

Abrégé

Efficiency in refrigerant charging work is addressed when a recovered refrigerant recovered from a first heat source unit is to be charged to a second heat source unit. A refrigerant charging method is a charging method used when a first heat source unit of an already installed refrigeration cycle apparatus in which a refrigeration cycle is to be performed by a refrigerant that circulates is to be replaced with a second heat source unit. The refrigerant charging method includes recovering a first refrigerant from an already installed refrigeration cycle apparatus and obtaining a recovered refrigerant and charging the recovered refrigerant and charging a second refrigerant whose composition differs from the composition of the recovered refrigerant to the refrigeration cycle apparatus after renewal that includes the second heat source unit.

To highly accurately determine whether a refrigerant amount in a refrigerant circuit is appropriate. An air conditioning apparatus comprises a refrigerant circuit in which a plurality of indoor units respectively including an indoor heat exchanger and an indoor expansion valve are connected to an outdoor unit including an outdoor expansion valve via a liquid-refrigerant connection pipe. Moreover, the air conditioning apparatus individually controls each of the indoor units to operate or stop. The air conditioning apparatus includes a controller. When at least one of the indoor heat exchangers functions as a radiator, the controller controls an opening degree of the indoor expansion valve and an opening degree of the outdoor expansion valve. The apparatus determines whether a refrigerant amount in the refrigerant circuit is appropriate on the basis of an amount of change corresponding to a change in state of a refrigerant between the indoor expansion valve and the outdoor expansion valve.
