Abstract
Saint-Petersburg State University of Refrigeration and Food Technologies Individual cryopools are devices for the general cryotherapy. Cooling cryopool is based on use of liquid nitrogen. Steams of nitrogen with temperature nearby 140 К are taken away from cryopool in atmosphere its top section. Steam movement reduces a supply of warmth heat conductivity to level of 4 Vt/m2. The warmth supply through the top section of pool in 1000 times is less than thermal emissions from a body of the patient. Thanks to steams of nitrogen warmth inflow through the top section is insignificant.

Keywords: cryotherapy, cryopools, heat conductivity, liquid nitrogen
