In this way, the position of the heat pump body 100 can be flexibly arranged according to the actual site requirement, and the cold air can be supplied into the room 1000 only by stretching or shrinking the air supply duct 200. For example, in order to avoid noise interference, the heat pump body 100 can be installed far from the room 1000, and the length of the air duct 200 can be extended to smoothly supply cold air into the room 1000; when the usage place is small, the heat pump body 100 can be installed to be close to the room 1000, and the cool air can be supplied to the room 1000 by only shortening the length of the air supply duct 200. The air supply pipeline 200 can be a telescopic corrugated pipe, or the air supply pipeline 200 can be formed by nesting a plurality of pipe sections, and the length of the air supply pipeline 200 can be flexibly adjusted.

Thus, when the indoor unit 1000 does not need to be cooled (for example, in autumn and winter), the cold air transmission path can be interrupted without installing the first pipe section 230 or removing the first pipe section 230, and the space occupied by the first pipe section 230 can be made free. When it is desired to cool the room 1000, the first pipe section 230 and the second pipe section 240 are simply connected. The detachable connection between the first pipe section 230 and the second pipe section 240 may be achieved by a plug-in fit manner (for example, the inner diameter of the first pipe section 230 is set larger than the outer diameter of the second pipe section 240, and only the second pipe section 240 needs to be inserted into the first pipe section 230 to achieve the communication between the first pipe section 230 and the second pipe section 240, and only the second pipe section 240 needs to be pulled out from the first pipe section 230 to achieve the separation between the first pipe section 230 and the second pipe section 240), or may be achieved by a snap-in fit manner (for example, a buckle is provided on the outer wall of the first pipe section 230, a hook is provided on the outer wall of the second pipe section 240, and the snap-in fit between the buckle and the hook is utilized to achieve the communication between the first pipe section 230 and the second pipe section 240, and the snap-in fit between the buckle and the hook is released, thereby achieving the separation between the first pipe section 230 and the second pipe section 240), or may be achieved by tightening the first pipe section 230 and the second pipe section 240 by a clamp The clamp is released to effect separation between the first tube segment 230 and the second tube segment 240.
