In the using process, under the action of the fan 13, indoor air enters from the air return opening 101 of the indoor unit 10, passes through the fan 13 and the flow channel, reaches the heat exchange cavity corresponding to the evaporator 12, and enters into the room from the air outlet 102 of the indoor unit 10.
As shown in fig. 3, the space enclosed by the housing 11 is divided into an airflow area 111 and an auxiliary area 112 in the transverse direction, the fan 13 and the evaporator 12 are located in the airflow area 111, the liquid separation pipe 15 and the gas collection pipe 16 are located in the auxiliary area 112 at positions corresponding to the evaporator 12, the throttling element 14 is located in the auxiliary area 112, and the liquid separation pipe 15 and the throttling element 14 are sequentially arranged in the longitudinal direction.
