Abstract
Suggested model covers the necessity of calculating the effect of frost formation, on the evaporator wall in cooling storage rooms, on the heat transfer efficiency between refrigerant and wet air. In it obtained analytical relationships for temperature distribution in both wall material and frost layer, overall heat transfer coefficient and the time of frost layer formation as a function of frost layer thickness.
