The weight of an AC copper compressor can vary depending on its size, capacity, and model. Typically, the weight of a standard residential AC copper compressor ranges from 8 kg to 15 kg (approximately 17.6 lbs to 33 lbs).
Regarding the specific 20kg compressor you mentioned, it's not possible to determine if it's a copper compressor solely based on its weight. Compressors are available in various materials, including copper, aluminum, and other alloys. The weight alone does not indicate the material used for the compressor.
The weight of a compressor is influenced by its design, size, and components. While copper compressors are commonly used in some air conditioning systems, aluminum compressors are also popular due to their lighter weight and lower cost.
To determine if a specific compressor is a copper compressor, you would need to check the manufacturer's specifications or inspect the compressor visually. The manufacturer's label on the compressor usually provides information about its material composition and other details.
Keep in mind that AC compressors can have different weight ranges depending on their intended use and application. If you are in doubt about the type or specifications of a particular compressor, it's best to consult the manufacturer or a qualified HVAC technician for accurate information.
