This kind of design makes through the flow area who adjusts first control valve or second control valve, can be so that the refrigerant flow to two heat exchangers 2 is different for two heat exchanger 2's heat transfer effect is different, and then makes the air-out of two air outlets 121 have different temperatures, realizes that indoor set 100 of air conditioner is to indoor subregion accuse temperature, thereby satisfies the user in different regions to the demand of comfortable wind temperature. The design can also adjust the flow area of the first control valve or the second control valve, so that the flow of the refrigerant flowing to the two heat exchangers 2 is the same, the heat exchange effect of the two heat exchangers 2 is approximately the same, and the indoor temperature is uniform.

Referring to fig. 5, an air conditioner according to an embodiment of the present invention includes an indoor unit 100 and an outdoor unit. The indoor unit 100 of an air conditioner is the indoor unit 100 of an air conditioner according to the first aspect of the present invention. The outdoor unit is connected to the indoor unit 100. The air conditioner can be a split wall-mounted air conditioner or a split floor type air conditioner.

According to the utility model discloses an air conditioner, through setting up above-mentioned air conditioning indoor unit 100, the air-out of two air outlets 121 of air conditioning indoor unit 100 can have different temperatures, is favorable to realizing the subregion accuse temperature of air conditioner, satisfies indoor different regional user's demand.
