INITIAL TEST RESULTS FOR A -80°C TURBO REVERSE BRAYTON AIR REFRIGERATOR

摘要：

A small and miniature Reverse Turbo Brayton Cycle (RTBC) air refrigerator performance test was conducted to verify its thermal and mechanical characteristic. Different kinds of heat exchanger configurations including plate-fin and plate heat exchanger were tested. Several different externally-pressurized (EP) or self-acting gas bearing combinations were applied and compared in turbo expander (TE) experiments. The temperature drop versus time curve of the refrigerator was presented and the relationship between refrigeration temperature and refrigeration capacity was obtained. The initial test results of this refrigerator have shown that the thermal and mechanical characteristics are satisfied.
