Abstract In this paper a miniature and ultraportable pression refrigeration system for personal
cooling has been developed and tested. To meet the demand of portability, several key ponents
have been utilized or developed such as a pressor, a miniature electronic expansion valve and a
microchannel plate-fin evaporator. In this way, the total weight of the miniature refrigerator is less than .
The system is tested under various conditions and the performance curves are presented. It is shown that the
miniature refrigeration system can yield a cooling capacity of 215 watts with COP at ambient temperature of
55°C with cold water temperature of 24°C to the cooling ves
