The built-in indoor unit shown in Figure 1 includes a casing 1, a fan 2 and an evaporator 3 arranged inside the casing 1, and the casing 1 is provided with at least one air inlet 4 and at least two air outlets 5 , and the casing 1 extends into at least two rooms, each of which has at least one air outlet 5 .

When the embedded indoor unit of the present application is a wall-mounted indoor unit, the casing 1 is embedded in the wall and protrudes into multiple rooms, so that each protruding room has at least one air outlet 5 , can selectively exchange heat for one room or multiple rooms according to the needs of users.

When the embedded indoor unit of the present application is a ceiling-mounted indoor unit, the housing 1 is hoisted on the ceiling and extends into multiple rooms in the ceiling, so that each room has at least one air outlet 5 , can selectively exchange heat for one room or multiple rooms according to the needs of users.

Wherein, one air inlet 4 on the housing 1 can supply air to all the air outlets 5, and the air inlet 4 can be arranged in any one room or in multiple rooms.

Preferably, the air inlet 4 is in one-to-one correspondence with the air outlet 5, and each room is provided with an air inlet 4 and an air outlet 5 to ensure that air can be sucked in and blown out from the same room, preventing Interference in rooms that do not exchange heat.

Preferably, the fan 2 is located at the center of the casing 1, especially the distance from the outermost side of the fan 2 to all the air outlets 5 is equal, the evaporator 3 is arranged on the upper side of the fan 2, and the The air passing through the air inlet 4 can pass through the evaporator 3 and then enter the fan 2, and then flow out of the outer casing 1 through the air outlet 5.

An air flow channel is formed between the air inlet 4 and the air outlet 5 on the housing 1 in the same room.

There are two air inlets and two air outlets, two fans 2, and one fan 2 is arranged in each airflow channel.

The number of the fan 2 is two, and one fan 2 is arranged in each air flow channel. By setting a fan 2 in an air flow channel, it can be ensured that when a room needs heat exchange, There will be no gas flow in the other airflow channel, thereby effectively avoiding technical problems such as noise and vibration in the other room.

The number of the evaporators 3 is two, and the two evaporators 3 are arranged in parallel inside the housing 1, and one of the evaporators 3 is arranged in each of the air flow passages, and one evaporator 3 is connected with one In cooperation with the fan 2, when a room needs heat exchange, no refrigerant flows into the evaporator 3 in the other airflow channel, that is, the evaporator 3 stops working, so that all the refrigerant can be supplied to the other evaporator 3. Further increase the heat exchange efficiency and the utilization rate of the refrigerant, and can effectively avoid technical problems such as noise and vibration in another room.
