This calculation is used in process engineering to determine refrigerant requirements for rapid-freeze cycles in food and pharmaceutical industries. It balances the sensible and latent heat loads of a product against the sublimation and warming enthalpy of solid carbon dioxide. The model incorporates an empirical loss factor to account for system inefficiencies and heat infiltration.
