In addition, each air outlet pipe 310 may be provided with one fresh air outlet 311 or at least two fresh air outlets 311. When one fresh air outlet 311 is arranged, the size of the fresh air outlet 311 can be large or small; it can be understood that the size of the fresh air outlet 311 is larger, the amount of the fresh air blown out in unit time is larger, and then the heat exchange efficiency of the fresh air passing through the heat exchanger 200 is higher, so that the indoor air quality is improved higher, and the comfort level of a human body can be improved faster. When the fresh air outlet 311 is provided with at least two, the at least two fresh air outlets 311 can be arranged at intervals in the length direction of the air outlet pipe 310, so that the area of the fresh air blown out of the air outlet pipe 310 through the heat exchanger 200 is large, the heat exchange efficiency is increased, and the comfort level of a human body is improved. The fresh air outlet 311 may be a hole-shaped structure, which may be a circular hole, a rectangular hole, a triangular hole or other special-shaped holes.
According to the technical scheme, the air outlet pipe 310 of the fresh air module 300 is arranged on the air inlet side of the heat exchanger 200, and the opening of the fresh air outlet 311 formed in the air outlet pipe 310 faces the heat exchanger 200, so that the wind blown out from the fresh air outlet 311 can be directly blown to the heat exchanger 200, and then is blown to the indoor after heat exchange is carried out through the heat exchanger 200. Therefore, the comfort level of the indoor user is improved, and the user is prevented from feeling two kinds of wind with different temperatures; meanwhile, the quality of indoor air is improved due to the mixing of fresh air. In addition, the opening of the fresh air outlet 311 faces the heat exchanger 200, so that the situation that the fresh air blown out from the fresh air outlet 311 blows up dust accumulated outside the casing 100 to cause indoor secondary pollution can be reduced. After the fresh air flows through the air outlet pipe 310, the fresh air is blown out from the fresh air outlet 311 of the air outlet pipe 310, so that the noise generated by the fresh air blown out from the fan by the air outlet pipe 310 is reduced, and the noise of the whole fresh air conditioner indoor unit is reduced.
Further, referring to fig. 2 to fig. 4, the air outlet pipe 310 extends along the length direction of the heat exchanger 200; the side wall of the air outlet pipe 310 is provided with a plurality of fresh air outlets 311, and the fresh air outlets 311 are distributed at intervals.

So set up, then when the amount of wind is certain regularly, the new trend when blowing towards air inlet end 312 direction, the wind speed through air outlet 320 can be bigger and bigger to can prolong the distance of sending out of new trend, guarantee that the new trend can blow to the one end that air outlet pipe 310 kept away from air outlet 320.
It is understood that the outlet nozzle 320 is a cylindrical structure for discharging air, and has a certain length. When a cross section (where the cross section is a section perpendicular to the length direction of the outlet) is made at any position of the outlet 320, the cross section has an opening, and the opening may be circular, rectangular, or other irregular shapes. When the opening of the air outlet nozzle 320 is circular, the air outlet nozzle 320 has an aperture, and the aperture in this embodiment is the diameter of the circular opening. When the opening of the air outlet nozzle 320 at a certain position is rectangular or other irregular shapes, the air outlet nozzle 320 has an air outlet area at the certain position, and the air outlet area is an area enclosed by the outer edge of the opening on the cross section of the air outlet nozzle 320 after the cross section of the air outlet nozzle is made at the certain position.
