Embodiment Construction

[0048] [First Embodiment]

[0049]

[0050] Fig. 1 shows a refrigerant circuit of an air conditioner including an outdoor unit according to a first embodiment of the present invention. The air conditioner 1 is a multi-type air conditioner for a building. A plurality of indoor units 3 and one or more outdoor units 2 are connected in parallel to form a refrigerant circuit 10 in which refrigerant can flow.

[0051] A compressor 11 , a four-way switching valve 12 , an outdoor heat exchanger 13 and an outdoor expansion valve 14 are included in the outdoor unit 2 , and an indoor expansion valve 15 and an indoor heat exchanger 16 are included in the indoor unit 3 . The four-way switching valve 12 and the indoor heat exchanger 16 are connected by a gas-side refrigerant communication pipe 17a, and the outdoor expansion valve 14 and the indoor expansion valve 15 are connected by a liquid-side refrigerant communication pipe 17b. A gas-side shutoff valve 18 and a liquid-side shutoff va...

Abstract

An outdoor unit of an air conditioner in which a wind whistling sound and a vibration noise due to airflow are reduced is provided. The outdoor unit includes an outdoor heat exchanger (13), a fan (29), a motor (70) for driving the fan (29), and a motor support table (63) for supporting the motor (70). The fan (29) blows air to the outdoor heat exchanger (13) and promotes heat exchange between refrigerant and air. The motor support table (63) is provided with a rectifying member (64), and the rectifying member (64) deflects air flowing toward the motor support table (63) in a predetermined direction.

Description

technical field [0001] The present invention relates to an outdoor unit of an air conditioner, and more particularly to an outdoor unit of an air conditioner in which a motor for driving a fan to rotate is arranged on the upstream side of an air flow relative to the fan. Background technique [0002] As an air conditioner, there is a so-called multi-type air conditioner for buildings in which a plurality of indoor units are connected to one or more outdoor units. In such an apparatus, an outdoor unit is generally installed on the roof of a building, and a refrigerant circuit is formed in such a manner that refrigerant can flow between the outdoor unit and indoor units installed in each room of the building. [0003] The outdoor unit of a conventional air conditioner has a rectangular parallelepiped casing, and a heat exchanger, a compressor, and other components are provided in the casing. In addition, a fan and a motor for driving the fan are provided on the upper portion ...
