The invention provides a cabinet air conditioner system.
As shown in fig. 1 and 2, fig. 1 is a schematic cross-sectional structure view of an indoor unit of a cabinet air conditioner system according to an embodiment of the present invention; fig. 2 is a schematic diagram of an outdoor unit of a cabinet air conditioner system according to an embodiment of the present invention.
The cabinet air conditioner system of the present invention includes an indoor unit 100 and an outdoor unit 200.
The indoor unit 100 includes a casing 120, an indoor heat exchanger 140 installed in the casing 120, a first wind wheel assembly 160, and a second wind wheel assembly 180; the indoor heat exchanger 140 includes a first heat exchange unit 142 and a second heat exchange unit 146, and the first heat exchange unit 142 and the second heat exchange unit 146 may be separately disposed or integrally formed. The casing 120 is provided with a first air inlet 102 corresponding to the first heat exchange unit 142, and the casing 120 is provided with a first air outlet 104 corresponding to the first air wheel assembly 160; the casing 120 is provided with a second air inlet 106 corresponding to the second heat exchange unit 146, and the casing 120 is provided with a second air outlet 108 corresponding to the second wind wheel assembly 180; the first air outlet 104 is in a strip shape, and the length direction of the first air outlet 104 is a vertical direction; the second outlet 108 is disposed above the first outlet 104, and the air blown out from the second outlet 108 has a component blowing out in a horizontal direction.
The outdoor unit 200 includes a compressor 220, an outdoor heat exchanger 240, a first throttling device 260, and a four-way valve 280; the compressor 220 delivers a refrigerant to the first heat exchange unit 142 and/or the second heat exchange unit 146 through the four-way valve 280. Specifically, when the compressor 220 provides a refrigerant to the first heat exchange unit 142 through the four-way valve 280, the first wind wheel assembly 160 operates to form a negative pressure in the casing 120; the external air enters the housing 120 through the first air inlet 102 under the negative pressure. After exchanging heat with the first heat exchange unit 142, the air is blown out from the first air outlet 104, so that cooling or heating is realized. Because the first air outlet 104 of this embodiment is vertically arranged on the casing 120, and the air output is large, the space can be rapidly cooled or heated, and the requirement of the user for rapid cooling or heating can be met.

When the compressor 220 simultaneously provides the refrigerant to the first heat exchange unit 142 and the second heat exchange unit 146 through the four-way valve 280, the first wind wheel assembly 160 and the second wind wheel assembly 180 simultaneously operate to further increase the speed of space cooling or heating.
According to the technical scheme, the compressor 220 is used for providing the refrigerant for the first heat exchange unit 142, and under the action of the first wind wheel assembly 160, the heat exchange is carried out between the external air and the first heat exchange unit 142, so that the space can be rapidly cooled or heated, and the rapid cooling or heating requirements of users are met; provide the refrigerant for second heat transfer unit 146 through compressor 220, under the effect of second wind wheel subassembly 180, outside air carries out the heat exchange with second heat transfer unit 146, can guarantee the even cooling of temperature in the big space, and can directly not blow to the human body, and then guaranteed user's comfort level.

The defrosting mode is not stopped: the first throttle device 260 is turned off (i.e., the first throttle device 260 is turned off), the second throttle device 500 is opened (i.e., the second throttle device 500 is made to have a throttling function), the first valve body 300 and the third valve body 600 are closed, and the second valve body 400 and the fourth valve body 700 are opened; the refrigerant discharged from the compressor 220 flows to the first heat exchange unit 142 through the four-way valve 280; enters the first pipeline 143 from the second port, exchanges heat with the first heat dissipation plate 141, and then flows out from the first port; after being throttled by the second throttling device 500, the refrigerant enters the second pipeline 147 from the fourth port, exchanges heat with the second heat dissipation plate 145, and then flows out from the third port; then, the refrigerant passes through the second valve body 400 and the fourth valve body, enters the outdoor heat exchanger 240, exchanges heat with the outdoor heat exchanger 240, and then returns to the compressor 220 through the four-way valve 280.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
