Description
Technical Field
The invention relates to the field of air conditioners, and particularly provides an outdoor unit for an air conditioner and the air conditioner.
Background
The split air conditioner is divided into an indoor unit and an outdoor unit, and an outdoor heat exchanger, a compressor with larger noise, a fan and the like are arranged in the outdoor unit; the electrical control circuit components and the indoor heat exchanger are mounted in the indoor unit. The fan drives outdoor air to enter from an air inlet of the outdoor unit and then flow into the outdoor heat exchanger. After the heat exchange between the air and the refrigerant in the outdoor heat exchanger, the air flows out of the outdoor unit through an air outlet of the outdoor unit.
In the prior art, the fans of the outdoor unit usually adopt axial flow fans, the air flow directions of the air suction side and the air discharge side of the axial flow fans are the same, and the air inlet and the air outlet of the outdoor unit are correspondingly arranged on two opposite side panels of the outdoor unit. An on-line pipe for transmitting the refrigerant, and a high pressure stop valve and a low pressure stop valve arranged on the on-line pipe for controlling the flow of the refrigerant are also arranged between the outdoor unit and the indoor unit. When the air conditioner needs to be overhauled, the refrigerant can be limited in the refrigerant storage device of the compressor by controlling the high-pressure stop valve and the low-pressure stop valve. The outdoor unit of the prior art generally has two shut-off valves on the other side panel different from the side panel on which the air inlet and outlet are provided.
Fig. 1 is a schematic view of an outdoor unit for an air conditioner in a different installation position in the related art. As shown in fig. 1, a conventional air conditioner 1a includes a conventional outdoor unit 10a, an indoor unit 20, and a connecting pipe 30. The conventional outdoor unit 10a includes: a housing 11a, the housing 11a having a front panel 111a and a rear panel 112a opposite to each other and a valve panel 113a perpendicular to the front panel 111a, the front panel 111a being provided with an air outlet (not shown), the rear panel 112a being provided with an air inlet (not shown), the valve panel 113a being provided with a shut-off valve 14; in the heat exchanger 12a in the prior art, the heat exchanger 12a in the prior art is located inside the housing 11a and has an air outlet end surface 121a and an air inlet end surface 122a which are opposite to each other, the air outlet end surface 121a faces the air outlet, and the air inlet end surface faces the air inlet; and a fan 13a, wherein the fan 13a is disposed between the air outlet end surface 121a and the air outlet to drive air to flow in from the air inlet and flow out of the outdoor unit 1a after flowing through the heat exchanger 12a in the prior art.
Referring to fig. 1, when the outdoor unit 10a of the prior art is installed, the air outlet of the outdoor unit needs to face the direction without obstacles to ensure the heat exchange effect of the outdoor unit. When the outdoor unit 10a of the prior art is installed at the predetermined installation position a on the building, the length of the connecting pipe 30 between the outdoor unit 10a and the indoor unit 20 of the prior art is short because the shutoff valve 14 faces the indoor unit 20; when the outdoor unit 1a of the related art is installed at the installation position B, since the cut-off valve 14 is far away from the indoor unit 20, the length of the line pipe 30 between the outdoor unit 10a and the indoor unit 20 is long, which results in waste of line pipe material.
In addition, if the outdoor unit is installed at a predetermined position and the shut-off valve faces an obstacle, the difficulty of maintenance is increased.
Therefore, there is a need in the art for a new solution to the above problems.

With continued reference to fig. 2, in one or more embodiments, the heat exchanger 12 is disposed upright in the second chamber 116 of the housing 11. In one or more embodiments, the heat exchanger 12 is configured as a flat plate and has a first end surface 121 and a second end surface 122. The first end surface 121 and the second end surface 122 are each substantially parallel to the first side panel 111 and the second side panel 112. The air from the first air opening 117 or the second air opening 118 flows into the heat exchanger 12 from the first end surface 121 or the second end surface 122 and exchanges heat with the refrigerant flowing in the heat exchanger 12, and then flows out of the heat exchanger 12 from the other of the first end surface 121 or the second end surface 122. In alternative embodiments, the heat exchanger 12 may be configured in other suitable shapes, such as an L-shape. The heat exchanger 12 includes, but is not limited to, copper tube fin heat exchangers, microchannel heat exchangers, and the like. In the L-shaped configuration, the first and second end faces 121, 122 are located on opposite sides of the longer portion of the heat exchanger 12, respectively.

The first motor is fixed to the first bracket and is fixedly connected to the first fan 131 via its drive shaft. The second fan 132 and the second support are both disposed between the second end face 122 of the heat exchanger 12 and the second air opening 118. The second motor is fixed to the second bracket and forms a fixed connection with the second fan 132 via its drive shaft. The first and second motors may drive the first and second fans 131 and 132 to rotate at different rotational speeds, respectively. Alternatively, the first fan 131 and the first bracket may also be disposed between the second end surface 122 and the second air opening 118; the second fan 132 and the second bracket may also be disposed between the first end surface 121 and the first air opening 117. In one or more embodiments, the first fan 131 and the second fan 132 are both configured as axial fans, and the aerodynamic performance of the fan blades is the same when rotating in forward and reverse directions.
In an alternative embodiment, the number of motor brackets and motors is one. In other words, the first fan 131 and the second fan 132 are driven by the same motor. In an alternative embodiment, the motor holder may not be provided, but the motor may be directly fixed to the chassis of the housing 11.
When the first fan 131 and the second fan 132 rotate forward simultaneously, the rotation speed of the second fan 132 is greater than that of the first fan 131, air flows into the outdoor unit 10 from the first air opening 117, then enters the heat exchanger 12 from the first end surface 121, flows out of the heat exchanger 12 from the second end surface 122 after heat exchange, and finally is discharged out of the outdoor unit 10 from the second air opening 118. When the first fan 131 and the second fan 132 are simultaneously rotated reversely, the rotation speed of the first fan 132 is set to be greater than that of the second fan 131, and the air flows into the outdoor unit 10 through the second air opening 118, then enters the heat exchanger 12 through the second end surface 121, flows out of the heat exchanger 12 through the first end surface 122 after heat exchange, and finally is discharged out of the outdoor unit 10 through the first air opening 117.
Fig. 4 is a schematic view illustrating an outdoor unit for an air conditioner according to the present invention in various installation positions. As shown in fig. 4, the present invention also provides an air conditioner 1. The air conditioner 1 includes an outdoor unit 10, an indoor unit 20, and a refrigerant communication pipe 30 for communicating a refrigerant between the outdoor unit 10 and the indoor unit 20.
When the outdoor unit 10 is installed at a predetermined installation position a on a building, the second side panel 112 faces a direction free from obstacles, the first side panel 111 faces an obstacle (here, a wall), and the first and second fans 131 and 132 are controlled to be simultaneously rotated in the forward direction. At this time, the second air opening 118 is an air outlet, the first air opening 117 is an air inlet, the stop valve 14 faces the indoor unit 20, and the length of the connecting pipe 30 is short; when the outdoor unit 10 is installed at a predetermined installation position B on a building, the first side panel 111 faces the direction of no obstacle, the second side panel 112 faces the obstacle, and the first fan 131 and the second fan 132 are controlled to be simultaneously rotated in reverse. At this time, the first air opening 117 is an air outlet, and the second air opening 118 is an air inlet. The shutoff valve 14 can also be directed toward the indoor unit 20, thereby shortening the length of the line pipe 30.
It should be noted that the installation positions of the outdoor units reserved on the building are variable. The installation positions a and B may be other possible cases, and do not limit the installation position of the outdoor unit 10.
