[0050] The first fresh air damper 221 includes a first free end and a first rotating shaft end. Optionally, the first rotating shaft end is connected to the fresh air baffle 24, and the first free end can rotate around the first rotating shaft end. When the first fresh air damper 221 is in a vertical state, the first fresh air damper 221 is in an open state. Figure 6 As shown in state 223; when the first fresh air damper 221 is in a horizontal state, the first fresh air damper 221 is in a closed state. Similarly, the second fresh air damper 222 includes a second free end and a second rotating shaft end. Optionally, the second rotating shaft end is connected to the fresh air baffle 24, and the second free end can rotate around the second rotating shaft end. When the second fresh air damper 222 is in a vertical state, the second fresh air damper 222 is in an open state, as shown in state 223.

The first fresh air outlet 201 is formed in the fresh air column 2, and the fresh air column 2 has a certain thickness. The first fresh air outlet surface P3 is obtained by extending along the inner wall of the first fresh air outlet 201 and passing the first fresh air edge 2011. The second fresh air outlet surface P4 is obtained by extending along the inner wall of the first fresh air outlet 201 and passing the second fresh air edge 2012.

It can be understood that when a6 is 0°, the third fresh air outlet plane P6 is parallel to the fourth fresh air outlet plane P7.

[0067] This makes the direction of the fresh air blown out of the second fresh air outlet 202 roughly perpendicular to the direction of the heat exchange air blown out of the second air outlet section 1022, thereby improving the mixing effect of the air delivered by the second fresh air outlet 202 and the air delivered by the second air outlet section 1022.

Similarly, the opening width L2 of the second fresh air outlet 202 is less than or equal to 0.2 times the width L of the fresh air baffle 24. This ensures that the opening widths of the first fresh air outlet 201 and / or the second fresh air outlet 202 are not excessively large, improving the uniformity of airflow at different height positions of the first fresh air outlet 201 and / or the second fresh air outlet 202. Optionally, L1 can be 0.2L, 0.15L, or 0.1L. Optionally, L2 can be 0.2L, 0.15L, or 0.1L.

[0071] This arrangement positions the first fresh air outlet 201 close to the middle section 242 of the fresh air baffle 24, improving the air mixing effect between the first fresh air outlet 201 and the first air outlet 101. Optionally, H1 can be 0.2L, 0.15L, or 0.1L. Optionally, H2 can be 3H1, 4H1, or 5H1.

[0072] Optionally, the distance between the third fresh air edge 2021 and the middle section 242 of the partition is H3, and the distance between the fourth fresh air edge 2022 and the front end 241 of the partition is H4, and H3≤0.2L; H4≥3H3.
