The air supply duct 101 has an air supply port and an air return port, the casing 10 has an air return side and an air supply side, and under the driving action of the fan assembly 20, the air flow on the air return side enters the air supply duct 101 through the air return port, and after heat exchange in the air supply duct 101, is sent out to the air supply side through the air supply port, and then flows back to the air return side of the casing 10 after entering the room, thereby forming a heat exchange cycle.

For example, when the ventilation opening 103 is disposed on the side of the electric control chamber 102 facing the air supply duct 101, the fan assembly 20 may be used to drive air flow through the electric control chamber 102 to dissipate heat of the electric control chamber 102.

The air in the housing 10 is sent to the air supply side of the housing 10 through the air supply port, and the air flow outside the housing 10 can be sent to the air return side of the housing 10 through the air return port. As shown in fig. 1, the housing 10 has an air duct 101 extending in the front-rear direction, and the front end of the air duct 101 forms an air outlet, and the rear end of the air duct 101 forms an air outlet, so that the front side of the housing 10 is the air return side of the housing 10, and the rear side of the housing 10 is the air supply side of the housing 10. In addition, the electric control chamber 102 is disposed on the right side of the air supply duct 101, so the left side of the electric control chamber 102 is the side of the electric control chamber 102 facing the air supply duct 101, and the right side of the electric control chamber 102 is the side of the electric control chamber 102 facing away from the air supply duct 101. In the description of the present invention, it should be understood that, directions or positional relationships indicated by terms such as "upper", "lower", "front", "rear", "left", "right", etc., are based on those shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the apparatus or elements to be referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

At least a portion of the vent 103 extends downward such that, when the airflow is directed into the electrically controlled chamber 102, even if dirt, dust, etc., is present or condensed water is generated, the downward extending portion of the vent 103 blocks the airflow from directly flowing into the electrically controlled chamber 102, thereby improving the protection of the electrically controlled chamber 102. In addition, the circulation of air flow is ensured, and the heat exchange effect can be improved.
