The air conditioner performs a refrigeration cycle of the indoor unit by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0068] The compressor compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0069] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the duct air conditioner can adjust the temperature of the indoor space.

[0070] The outdoor unit is a part of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0078] The front plate 12 is connected to the edge of the bottom plate 11 and extends upward from the edge of the bottom plate 11 . The bottom plate 11 and the front plate 12 form a receiving space.

[0079] Continue to refer Figure 2 The front plate 12 is provided with a vent 13, thereby improving the structural consistency of the ceiling 1 and the overall aesthetics of the duct unit. The vent 13 is connected to the accommodation space.

[0080] refer to Figure 1 The duct machine may include a body 2. The body 2 is installed in the accommodating space.

[0081] An installation cavity is formed inside the body 2. The installation cavity is used to accommodate and fix various components inside the body 2, so as to prevent foreign objects from colliding with the various components inside the body 2.

[0082] In some embodiments of the present application, the body 2 may include an air-conditioning air inlet 21 .

[0083] The air-conditioning air inlet 21 is communicated with the installation cavity, and serves as an inlet for the external air of the body 2 to flow in, allowing the air in the accommodating space to enter the installation cavity through the air-conditioning air inlet 21 .

[0084] In some embodiments of the present application, the body 2 may include an air-conditioning outlet 22 .

[0085] The air conditioning outlet 22 is connected to the installation cavity, and serves as an outlet for the heat exchange air flow in the body 2 to flow out, allowing the air flow in the installation cavity to flow out through the air conditioning outlet 22 .

[0086] The air-conditioning air inlet 21 may be disposed at one end of the machine body 2 , and the air-conditioning air outlet 22 may be disposed at the other end of the machine body 2 .

[0087] The air outlet 22 is arranged close to the vent 13 relative to the air inlet 21. The heat exchange airflow blown out by the air outlet 22 can flow into the room through the vent 13.

[0088] The body 2 is roughly in the shape of a rectangular parallelepiped. Figure 3 to Figure 5 The air-conditioning air inlet 21 and the air-conditioning air outlet 22 are respectively located at two ends of the body 2 in the width direction of the body 2.

[0093] The installation cavity can be formed by the top plate 23, the bottom plate and the two side plates.

[0094] In some embodiments of the present application, the duct unit may include an indoor heat exchanger 3 .

[0095] refer to Figure 6 In some embodiments of the present application, the duct air conditioner may include an indoor heat exchanger 3. The indoor heat exchanger 3 is disposed in the machine body 2 and performs heat exchange on the air entering the machine body 2.

[0096] In some embodiments of the present application, the duct air conditioner may include a heat exchange fan 4. The heat exchange fan 4 is disposed in the installation cavity, and is used to drive the indoor air outside the body 2 into the installation cavity through the air conditioning inlet 21, and to make the air in the installation cavity flow along the air conditioning inlet 21 toward the air conditioning outlet 22.

[0097] In some embodiments of the present application, the heat exchange fan 4 may be a cross-flow fan.

[0098] The crossflow fan is extended along the length direction of the body 2. That is, the length direction of the body 2 is the axial direction of the crossflow fan. Since the crossflow fan is small in size, the size of the duct fan is further reduced, the depth of the ceiling 1 is reduced, the problem of room oppression is solved, and the aesthetics of the room is improved.

[0099] Due to the characteristics of the cross-flow fan, the cross-flow fan is arranged close to the air outlet 22 of the air conditioner, and the indoor heat exchanger 3 is arranged close to the air inlet 21 of the air conditioner. The cross-flow fan is located between the air outlet 22 of the air conditioner and the indoor heat exchanger 3 .

[0100] In some embodiments of the present application, the indoor heat exchanger 3 may be a multi-stage heat exchanger.

[0101] refer to Figure 6 The indoor heat exchanger 3 includes three heat exchange sections, which are connected in sequence to form a nearly V-shaped structure, with the open end of the V-shaped structure facing the crossflow fan, and the closed end of the V-shaped structure facing the air inlet 21 of the air conditioner. This arrangement increases the heat exchange area of ​​the indoor heat exchanger 3, improves the heat exchange efficiency of the duct fan, and increases the amount of air exchanged.

[0102] The multi-stage heat exchanger has a semi-enclosed structure, and part of the cross-flow fan is arranged in the semi-enclosed structure of the indoor heat exchanger 3, so that the cross-flow fan and the indoor heat exchanger 3 are transformed from being originally separately arranged to being overlappingly arranged. While the volume of the cross-flow fan and the indoor heat exchanger 3 remains unchanged, the space occupied by the indoor heat exchanger 3 and the cross-flow fan is greatly reduced.

[0103] The duct unit may include a water tray 24. The water tray 24 is disposed at the bottom of the installation cavity to receive condensed water flowing down from the indoor heat exchanger 3 when the duct unit is working. The water tray 24 is provided with a drain port to discharge the condensed water in the water tray 24 out of the duct unit.

[0104] Of course, in some other embodiments, the heat exchange fan 4 may be a centrifugal fan. The centrifugal fan is closer to the air inlet 21 of the air conditioner relative to the indoor heat exchanger 3. The indoor heat exchanger 3 is arranged between the air outlet 22 of the air conditioner and the centrifugal fan.

[0111] The air conditioner outdoor unit may include an outdoor fan. The outdoor fan may be arranged in an outdoor installation cavity.

[0112] The rotation of the outdoor fan causes the outdoor air to enter the outdoor installation cavity from the outdoor air inlet to exchange heat with the outdoor heat exchanger, and the outdoor air after heat exchange flows out of the outdoor installation cavity from the outdoor air outlet.

[0113] The air conditioner may include a compressor, which is arranged in the outdoor installation cavity.

[0114] The air conditioner may include a throttling device. The throttling device is used for throttling. The throttling device may be arranged in an outdoor installation cavity.

[0115] The air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0116] The compressor compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0117] The throttle device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0118] The evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas in a low temperature and low pressure state to the compressor.

[0119] The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0120] Among the indoor heat exchanger 3 and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger 3 is used as a condenser, the air conditioner is used as a heater in the heating mode, and when the indoor heat exchanger 3 is used as an evaporator, the air conditioner is used as a cooler in the cooling mode.
