Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning installation, and more specifically to a central air-conditioning hanging structure. Background Art

[0002] Central air conditioning refers to a large air-conditioning system, which consists of a main unit and a terminal. The main unit is divided into a water-cooled unit and an air-cooled unit. The terminal equipment mainly consists of an air-conditioning unit and a fan coil unit. When installing the central air-conditioning indoors, you need to use lifting equipment to lift the air-conditioning equipment to the top of the room.

[0003] The current lifting structures mostly rely on pulleys and ropes. When in use, the pulley is first installed on the roof using expansion bolts, and then the air-conditioning indoor equipment is lifted up by pulling the rope with manpower or an external winch. However, when using the rope for lifting, since the rope is soft and is limited by the pulley height, it is difficult to lift the air-conditioning equipment close to the roof. During the operation, external personnel are required to assist in lifting the air-conditioning equipment, which has the disadvantages of being difficult and cumbersome to operate.

[0004] In view of this, the utility model proposes a central air-conditioning hanging structure to solve this problem. Utility Model Content
