There seems to be a lower size limit for conventional, compressor-based refrigeration. The result is that portable cooling devices are always simple fans, or at best, evaporative cooling units. What prevents conventional refrigeration and air conditioning from working at sizes much smaller than a dorm refrigerator?

because its useless. AC doesnt emit cold air, it makes warm air around an area colder. If youre going to have a portable AC that will work, its either you cool the whole earth or you make a portable room where you are inside and cool that area.
Or put it under your clothes it will probably work just like on astronauts
Also there are already portable refrigerators
