When the two sets of scale factors are set, different scale factor sets can be determined by performing experimental data in different working modes of the air conditioner. For example, the value of each scale factor in the first scale factor group can be determined through experiments by calculating under the condition that the air conditioner works in the cooling mode; the value of each scale factor in the second scale factor group can be determined through experiments by calculating under the condition that the air conditioner works in the heating mode.
Generally, because the operating mode of the air conditioner also includes dehumidification, air supply and the like, the proportion factor set in the dehumidification mode and the air supply mode can be determined, and the outlet air temperature of the air conditioner can be calculated by combining the method for calculating the outlet air temperature of the indoor unit of the air conditioner provided by the embodiment of the invention.
