1. Background and significance of the standard
GB/T 35753-2017 "Brackets for mounting outdoor air conditioners" is an important standard in China for the safety and reliability of outdoor air conditioner installation. The standard is under the jurisdiction of the National Technical Committee for Standardization of Household Appliances, and the main drafting units include Haier, Gree and other well-known domestic home appliance companies.

2. Comparison of standard frames
| Dimensions | Wall-mounted bracket | Platform bracket | Material requirements |
|---|---|---|---|
| Applicable cooling capacity range (W) | <5000W and 5000≤CC≤7500W | ≥5000W | Q235A performance requirements |
| Base material thickness (mm) | ≥2.0 and ≥2.2 | - | Hot-rolled steel/galvanized steel plate |
| Structural requirements | Reasonably distribute bolt holes | Platform structure | Anti-corrosion treatment |
3. Implementation suggestions
3.1 Selection and installation considerations
Air conditioner outdoor unit bracket should be selected according to the cooling capacity of the air conditioner and the installation environment. For wall-mounted brackets, special attention should be paid to the wall structure and load-bearing capacity; platform brackets are suitable for high-power air conditioners.
3.2 Installation and maintenance
During installation, GB17790 "Installation Specifications for Household and Similar Air Conditioners" should be followed to ensure that the length of the expansion bolts meets the requirements to avoid affecting the fixing effect due to the insulation layer. Bracket accessories such as bolts, spring washers, etc. need to be checked regularly to prevent loosening or corrosion.
