when 2600W is not more than Q not more than 2700W, 12m2≤A≤14m2And 1900m3/h≤B≤2100m3H is used as the reference value. For example, when 2600W ≦ Q ≦ 2700W, the heat exchange area A of the outdoor heat exchanger 100 may be 12m2，13m2Or 14m2And the air quantity B of the outdoor fan can be 1900m3/h、2100m3H or 2100m3/h；
When Q is more than or equal to 3500W and less than or equal to 3600W, 22m2≤A≤24m2And 2100m3/h≤B≤2300m3H is used as the reference value.
