2. Performance: the imported compressor has high refrigeration efficiency, low noise, low failure rate and excellent workmanship;
3. Service life: The service life of imported compressors is generally higher than that of domestic compressors.
Let's talk about domestic factories first. There are freezers: Beijing Embrack Snowflakes Brazil Embrack Brazil Aspala Slovakia Aspala Tianjin zanussi (ACC) Danfoss Wuxi Panasonic France You Mei Le France Taikang Brazil Taikang USA Taikang Samsung freezer has Shenyang wheels Beijing Bisell Bristol Turin USA This is the most used imported press.
Domestic brands are better, such as Huangshi Northeast Taizhou Lejin LG Jiangsu Baixue Hangzhou Wansheng Guangzhou Huaguang Wanbao Jiasibeila Qingdao Lihai Sichuan Danpu freezer Hangzhou Grain Wheel. ?
In fact, foreign brands are purely imported now, which is good but not guaranteed. The quality of the machines produced by the remaining foreign brands in China is the same as that of Huangshi Dongbei and Gasibela in China. Almost the same or even better in some respects. ? The rest are Wansheng, Baixue and LG, and the quality is very average.
Extended data:
main performance
Input and output power, performance coefficient, refrigeration capacity, starting current, working current, rated voltage, frequency, cylinder volume, noise, etc. To measure the performance of a compressor, we mainly compare it from three aspects: weight, efficiency and noise.
According to the national standard, the safety performance test was carried out according to the project specified in GB4706. 17-2004. The main items are electrical strength, leakage current, locked rotor and overload operation test.
The performance test of air-conditioning compressor is carried out according to GB5773-2004.
In addition, when there are major changes that may affect the product performance during product finalization and production, when the product has been continuously produced for more than one year, and when the factory inspection results are quite different from the type test, the type test must be carried out.
