R & D STRENGTH
Briliant's professional production and processing technology and outstanding design quality are the cornerstones and premise of Briliant's refrigeration industry. Briliant adheres to the scientific testing method, which is the best quality assurance and commitment of Briliantto customers. Briliant will open the first brand of refrigeration compressors, so that customers can truly understand the true meaning of quality.“GB/T10079-2018Single-stage reciprocating refrigerant compressor (unit)” new national standard for the first time put forward the concept of "accelerated life", mainly for the domestic industry generally on the compressor body, crankshaft and other materials on the application of low standards, strict requirements, appeared It can be used at the beginning, and after a period of time, the quality of the life cycle is generally severely declining. The new national standard stipulates that the range of noise and cooling capacity in the life cycle of the compressor does not exceed 3dB(A) and 5% of the new machine respectively.
TESTING CENTER
Briliant insists on scientific and professional testing methods constantly. The company has built three refrigeration compressor performance testing stations and an online testing assembly line. The refrigeration compressor performance testing stations covering semi-hermetic refrigeration piston compressors and semi-hermetic refrigeration screw compressors. Our online testing process covers key parameters such as airtightness testing, forward and reverse voltage, current, oil pressure, and volume flow rate for each refrigeration compressor. We also monitor and record the performance of refrigeration compressors under different operating conditions in real-time. By obtaining real-time data five times and generating an average value, we can more accurately evaluate the conventional performance indicators of refrigeration compressors, ensuring that each refrigeration compressor leaves the factory without any quality defects.The refrigeration compressor performance testing stations differ from the online testing assembly line in that the former adopts imported high-precision measuring instruments. The performance testing stations are built based on the “GB/T5773-2004The method of performance test for positive displacement refrigerant compressors” and the refrigeration compressor performance testing is conducted based on the " GB/T 10079-2018 Single-stage reciprocating refrigerant compressor(unit) "and" GB/T19410-2018 Screw refrigeration compressor".
