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. The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase 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 cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant.

Referring to fig. 3 to 6, the casing 10 extends in the up-down direction, and a plane perpendicular to the up-down direction is set as a second reference plane, and the cross-sectional area of the blocking member 50 on the second reference plane gradually increases in a direction away from the heat exchanger 40. Specifically, a plane perpendicular to the up-down direction is set as the second reference plane, and the cross-sectional area of the blocking member 50 on the second reference plane is gradually increased in the direction away from the heat exchanger 40, so that the blocking member 50 can naturally guide the wind flowing through the heat exchanger 40 into the first air duct member 21 and the second air duct member 22 after separating the wind, thereby making the flow path of the wind smoother and improving the working stability of the vertical air conditioner 100.

Further, one end of the barrier member 50 far away from the heat exchanger 40 abuts against one side of the rear end of the first air duct member 21 and one side of the rear end of the second air duct member 22, which are close to each other, so that on one hand, the leakage of air from the connecting position of the barrier member 50 and the rear end of the air duct assembly 20 can be prevented, the air volume loss can be reduced, and on the other hand, the retention of air in an included angle formed between the side of the rear end of the first air duct member 21 and the side of the rear end of the second air duct member 22, which are close to each other, can be prevented, so that the air inlet efficiency of the vertical air conditioner 100 can be improved, and the generation of noise can be prevented, thereby further improving the working performance of the vertical air conditioner 100.

In addition, the axial lengths of the first cross flow fan 31 and the second cross flow fan 32 may be set to be the same, so that the acting ranges of the first cross flow fan 31 and the second cross flow fan 32 in the axial direction may be the same, the versatility between the first cross flow fan 31 and the second cross flow fan 32 is enhanced, and the production and manufacturing of the floor air conditioner 100 are facilitated, and the axial lengths of the first cross flow fan 31 and the second cross flow fan 32 may also be set to be different, so that the acting ranges of the first cross flow fan 31 and the second cross flow fan 32 in the axial direction may be different, the air outlet effects of the first air outlet 11 and the second air outlet 12 of the floor air conditioner 100 are different, so that design variables may be added to the air outlet effects of the first air outlet 11 and the second air outlet 12 of the floor air conditioner 100, and the designability of the floor air conditioner 100 may be further improved. In actual production manufacturing, the axial lengths of the first and

second crossflow fans

31 and 32 can be selectively designed according to different production requirements.
