no. 1 Embodiment approach

[0023] Such as figure 1 As shown, the outdoor unit 10 of the air conditioner has a rectangular box-shaped metal outdoor unit body 11 . In the front cabinet 12 constituting the front surface of the outdoor unit main body 11, an air outlet 121 in which a fan cover is fitted is provided. An integrated valve body cover 14 serving as a side cover is detachably attached to the right side casing 13 constituting the right side of the outdoor unit main body 11 . The upper surface of the outdoor unit body 11 is constituted by a top plate 15 , and the left side of the outdoor unit body 11 is constituted by a left side casing 16 . The back side of the outdoor unit main body 11 is constituted by an unshown rear cabinet, or is formed in an open state. In the left side cabinet 16 , grid portions are formed at predetermined intervals in the vertical direction thereof, and openings are formed between these grid portions. The rear cabinet has grid portions formed at predetermined intervals i...

no. 2 Embodiment approach

[0068] Next, a second embodiment will be described. Such as Figure 10 As shown, in the converter device 200, corresponding to the three step-up circuits 53A, 53B, and 53C, there are three power factor improvement control units 300A, 300B, and 300C. Furthermore, each power factor improvement control unit 300A, 300B, 300C individually controls the drive of the corresponding booster circuit 53A, 53B, 53C according to the drive command from the main control unit 400 . To these power factor improvement control units 300A, 300B, and 300C, the voltage values ​​of the voltage division points of the output voltage detection circuit 91 are respectively input. In addition, the temperature detection values ​​of the temperature detection sensor 631 are respectively input to these power factor improvement control units 300A, 300B, and 300C.

[0069] According to this embodiment, the booster circuits 53A, 53B, and 53C can be individually driven according to the magnitude of the output vol...

Abstract

The present invention relates to an inverter device of an air conditioner, which has a substrate, a plurality of boosting circuits, and a control mechanism. The substrate is installed so that cooling air flows through the lower surface side thereof. The booster circuits are respectively mounted on the lower surface side of the substrate. The control mechanism switches the number of driven booster circuits according to the size of the load.

Description

technical field [0001] Embodiments of the present invention relate to an inverter device of an air conditioner. Background technique [0002] Conventionally, an inverter device included in an air conditioner has generally been considered to have a configuration including two booster circuits. However, when installing the inverter device on the air conditioner, it is relatively easy to install the inverter device inside the outdoor unit body due to design constraints such as the positional relationship with the compressor or the outdoor blower, and the size of the space inside the outdoor unit body. The part where the space is secured is the part that is installed obliquely above the outdoor blower and the part above the compressor. Furthermore, the electrical components accommodated inside the inverter device are mainly mounted on the lower surface of the substrate in a hanging state. At this time, among the electrical components constituting the booster circuit, component...
