Abstract
WBC is a technique that is based on supercooling a patient’s body to stimulate skin cold receptors at the depth of 0.15 мм from the skin surface forming a signal of maximum intensity at the temperature of –2 о С. Heat removal by gas with the temperature of not warmer than –130 о С allows localizing body supercooling zone at the depth of receptors.
KRION performed a research study to estimate maximum intensity of heat removal and necessary power consumption. The results determined requirements for consumption and power supply of cryo chamber that is crucial for efficiency and safety of WBC. The research was carried out by the mathematical models of WBC object (human body surface) and a cryosauna cabin. To perform an effective WBC procedure it is necessary to remove 3.8 kW of heat from the body surface. Taking into account total refrigerating capacity, the cryostatting system for a single-seated cryo chamber has to remove is as little as 6.4 kW of heat from the temperature level of –130 о С. Therefore, the cryotherapy machine should be based on a refrigerator of 47 kW power or nitrogen cooling system with refrigerating medium consumption of 0.025 kg/s or 4.45 kg per cryotherapy procedure.
The use of nitrogen cooling for optimal WBC zone results is effectively performed with KRION cryosaunas.
