Article present analysis of calculation methods to predict heat transfer coefficient of in-pipe boiling natural refrigerants like carbon dioxide, ammonia and propane. Analysis were perform for existing calculation methods prepared for synthetic refrigerants and consisted of number of points within ±50%, mean absolute error and average deviation.
