[0002] Central air conditioning, also known as centralized air conditioning system or central air conditioning system, is a system used to adjust the temperature and humidity of multiple rooms or the entire building. Central air conditioning system can provide customized temperature control solutions for different areas as needed, and is suitable for commercial buildings, office buildings, hotels, hospitals, large shopping malls and other places. Compared with traditional split air conditioners, central air conditioning systems can more effectively control the air quality and temperature of the entire building, while having higher energy efficiency and lower operating costs.

[0003] Central air conditioning consists of an indoor unit, an outdoor unit, a compressor, refrigerant pipes, an air handling unit, a fan coil unit and a control system. When installing, the indoor unit is generally fixed on the roof of the building. When fixing, the edge of the indoor unit is generally fixed with fixing holes or a mounting plate with fixing holes. When installing, holes are drilled on the building according to the fixing holes of the indoor unit, and expansion bolts are fixed. The installer then lifts the indoor unit, aligns the fixing holes with the expansion bolts, passes the expansion bolts through the fixing holes, and then fixes them with nuts.

[0004] When fixing the indoor unit of the air conditioner, the volume of the indoor unit of the air conditioner is generally large. When lifting the indoor unit of the air conditioner, two installers are required to make the indoor unit of the air conditioner contact with the expansion bolts. When fixing the indoor unit of the air conditioner, the installers are required to hold the indoor unit of the air conditioner while using tools to fix it. The whole fixing process is rather troublesome. Summary of the invention

The present application provides a central air conditioning installation system and construction method.

[0015] By adopting the above technical solution, the indoor unit of the air conditioner pushes the moving component, and the moving component pushes the support plate, so that the reinforcement buckles on the support plate are moved closer to the mounting plate and the support block, and finally the reinforcement buckles on the two support plates are buckled at the bottom of the support block, thereby further fixing the indoor unit of the air conditioner and improving the stability of the installation of the indoor unit of the air conditioner.
