摘要： To provide an air conditioner that is capable of outputting plural sets of data while controlling an increase in the size of a printed wiring board. The air conditioner is comprising an EEPROM (10), a switch (20) and a printed wiring board (30). The EEPROM (10) records at least two sets of data of whether or not an option function is being executed and a drive condition of a compressor (61) relating to air conditioning that the printed wiring board (30) acquires. The switch (20) receives display setting data indicating either one of the two sets of data. The printed wiring board (30) includes an output port (35) that alternatively outputs one of the data of whether or not the option function is being executed and the data of the drive condition of the compressor (61), and the printed wiring board (30) performs data output processing from the output port (35) in accordance with the display setting data that the switch (20) has received.

摘要： When an abnormality occurs in a refrigeration cycle, the inverter motor provided in the air conditioner is stopped reliably and contacts of the main relay are prevented from degradation and fusion. A power circuit 1 of the air conditioner includes a rectifier circuit RC, a capacitor C (smoothing unit), a main relay 10 provided on a current path between the rectifier circuit RC and the capacitor C, an inverter circuit 30, a microcomputer 100, and a delay circuit 40. The microcomputer 100 has an inverter circuit control unit 110, a main relay opening/closing control unit 120, a waveform forced cut-off unit 130, and a cut-off signal output unit 140. Where a high-pressure switch 200 (abnormality detection unit) detects a high-pressure abnormality and outputs a high-pressure abnormality signal to the waveform forced cut-off unit 130 when the main relay 10 is in a closed state, the waveform forced cut-off unit 130 electrically cuts off the inverter circuit control unit 110, and the cut-off signal output unit 140 outputs a cut-off signal, which sets the main relay 10 to the open state, to the main relay 10 via the delay circuit 40.

摘要： The invention relates to a power conversion apparatus including a converter circuit and an inverter circuit. The invention allows more precise output control of the inverter circuit than a power conversion apparatus in which the output control is performed based on a current value only, thereby improving operation efficiency. A current sensor (17) detects input current of the inverter circuit (3), and a voltage sensor (15) detects input voltage of the inverter circuit (3). A power value calculator section (33) in an inverter microcomputer (30) obtains a power value based on the input current and the input voltage. The inverter microcomputer (30) and the control microcomputer (40) perform droop control of reducing the output of the inverter circuit (3) to make the power value smaller than a predetermined power value.

摘要： When a defect is generated in an actuator of an outdoor unit, the actuator is automatically restarted. An outdoor unit (41) includes an outdoor unit control circuit (411), an inverter substrate (412) and a compressor (413). Periodic communication showing the operating condition of the inverter substrate (412) is set from the inverter substrate (412) to the outdoor unit control circuit (411). Thus, when the communication is performed normally, the drive of the compressor (413) is changed to a power saving process according to the necessity of the power consumption and the operating condition of the inverter substrate (412). When the communication is defective, the power-on reset is done to the inverter substrate (412).
