Compressor specifications are typically categorized based on input power, with each grade usually differing by approximately 50W. Additionally, they are also classified according to cylinder volume, which plays a key role in determining the unit’s capacity and efficiency.
Key performance indicators for compressors include input and output power, coefficient of performance (COP), cooling capacity, starting current, operating current, rated voltage, frequency, cylinder volume, and noise levels. When evaluating a compressor's overall performance, it is essential to compare its weight, energy efficiency, and noise output to ensure optimal operation and user comfort.
According to Chinese national standards, safety testing for compressors follows the requirements outlined in GB4706.17-2004. This includes tests such as electrical insulation strength, leakage current, motor stalling, and overload operation to ensure safe and reliable performance.
The performance testing of air conditioner compressors is conducted in accordance with GB5773-2004, which sets specific criteria for measuring efficiency, reliability, and operational stability under various conditions.
In cases where there are significant changes in product design or manufacturing processes that may impact performance, or when production has continued for over one year without any type test, a type test must be performed. This ensures consistency and compliance with required standards, especially if factory inspection results differ significantly from previous type tests.
For packaging, storage, and transportation, compressors are generally handled according to agreed contract terms. Large-scale imports are commonly packed in cartons and shipped in containers. It is important to secure the compressor within the package to prevent damage from moisture and vibration. Compressors should not be stored or transported upside down, and they should be kept in a well-ventilated warehouse with humidity below 80% and no presence of corrosive gases.
Precautions must be taken during storage and transport. The sealing rubber plug should only be removed when the compressor is in use. If the plug becomes loose or falls off during transit, the unit must be inspected and repaired before being put back into storage.
All refrigerator and air conditioner compressors must obtain CCC certification before they can be legally sold in China, ensuring they meet national safety and quality standards.
Major importing countries include Germany, the United States, Italy, Japan, Denmark, Brazil, and South Korea. Despite improvements in domestic production through technology upgrades and equipment modernization, China still relies on some imported compressors to meet market demand.
