Abstract:
Vapor compression refrigeration is considered as ideal miniature cooling system for miniature electronic systems and portable cooling systems. Many applications of the miniature refrigeration system are working under the situations (such as aviation field, individual combat system and automobile air conditioning, etc.) that exist bump, tilt, and even flip, which will severely degrade the performance of the miniature refrigeration system. In order to study the influence of compressor's tilt angle on refrigeration system, a test bench was built and the performance experiments were made. The results show that the compressor's tilt angle has a great impact on the refrigeration system performance. When the compressor worked at the maximum tilt angle of 60A degrees, COP-c and COP-h of the system change periodically. When the compressor works in full load, the maximum tilt angle for compressor is 20A degrees. When the compressor tilt angle is 15A degrees, there is an optimal amount of refrigerant charge, and corresponding COP-c and COP-h reach the maximum of 2.9 and 3.9, respectively.
