PROBLEM TO BE SOLVED: To omit a test of a whole substrate when performing replacement of an IPM and to reduce the number of types of an inverter device.SOLUTION: A refrigeration device forms a refrigeration cycle by including: a compressor for compressing a refrigerant; a motor for driving the compressor; a heat exchanger for exchanging heat between the refrigerant and air; a fan for blowing air to the heat exchanger; and a fan motor for driving the fan. The refrigeration device includes: a converter circuit for converting AC power from an AC power supply to DC power; an inverter circuit for converting the DC power generated by the converter circuit to AC power and outputting it to the motor; a first substrate in which a driver circuit for controlling the inverter circuit is provided; and a second substrate in which a microcomputer for controlling the driver circuit is provided. The first substrate and the second substrate are separate bodies respectively and they are electrically connected. |
