Taking a commercial indoor unit of an air conditioner with four-directional air outlet as an example, referring to fig. 1, the indoor unit comprises a casing, the casing is of an approximately square casing structure, the casing comprises a bottom panel 1 and four peripheral side panels 2 arranged on the bottom panel 1, and four air outlets, namely an air outlet a, an air outlet B, an air outlet C and an air outlet D, are symmetrically arranged around the bottom panel 1. Be equipped with heat exchanger 3 in the casing, heat exchanger 3 is around setting up along the circumferential direction of casing, and two tip of heat exchanger 3 pass through connecting plate 4 fixed connection. The fan 6 is arranged inside the heat exchanger 3, and airflow blown out from the fan 6 flows out from the air outlet after heat exchange of the heat exchanger 3, so that air conditioner adjustment is realized. As can be seen from fig. 1, the connection position of the two ends of the heat exchanger 3 is between the air outlet a and the air outlet D. A fresh air opening 7 and a water pump 5 are arranged in the shell, the fresh air opening 7 is located between the air outlet A and the air outlet B, and the water pump 5 is located between the air outlet C and the air outlet D. The water pump 5 is used for discharging condensed water generated by the heat exchanger 3 during operation in time, and is beneficial to improving heat exchange efficiency. Because fan 6 is circular motion and heat exchanger 3 is not regular shape around fan 6, the uneven problem of flow appears that so can't avoid, and this problem has been aggravated more to the separation of inside water pump 5, fresh air inlet 7 and heat exchanger connecting plate 4 to influence the air-out homogeneity of air outlet, influence the user and use experience.
Experiments show that the air outlet A is influenced by the fresh air inlet 7 and the heat exchanger connecting plate 4, and the air quantity of the air outlet A is slightly smaller than the air outlet B and the air outlet C. The internal flow channels of the air outlet B and the air outlet C are relatively wide, and the air quantity is almost equivalent. Air outlet D receives the shunt tubes of water pump 5, heat exchanger 3 and the influence of heat exchanger connecting plate 4, and the amount of wind is minimum in four air outlets, and the user can obviously perceive and be different from other air outlets. When the rotating speed of the fan is 800rpm, the difference between the air quantity of the air outlet B and the air outlet C is within 3 cubic meters per hour. The air quantity of the air outlet A, which is 10 cubic meters per hour different from that of the air outlet B and the air outlet C, accounts for 5%, and the air quantity of the air outlet D, which is 50 cubic meters per hour different from that of the air outlet B and the air outlet C, accounts for 26%. The uneven second problem of air outlet is air outlet condensation, because do not have enough amount of wind to blow away the moist hot-air on every side, lead to cold and hot air current to intersect, structural component condensation around the air outlet.

< basic operation principle of air conditioner >
The air conditioner performs a refrigeration cycle of the air conditioner 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.
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. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioner is used as a heater in a heating mode when the indoor heat exchanger is used as a condenser, and as a cooler in a cooling mode when the indoor heat exchanger is used as an evaporator.
