When calculating the oil heating heat exchange area of the storage tank, the average temperature of the oil is questionable
Thread Content
When calculating the heat exchange area for heating oil in a storage tank, the calculation formula for the average oil temperature ty involves the denominator term (oil heating starting temperature tys - medium temperature around the oil tank ti)； If the temperature of the oil in the tank is the same as the temperature of the medium around the tank, for example, the oil tank has been storing oil for a long time, and the oil temperature is consistent with the outside temperature, the denominator term is 0. How to deal with this denominator term in actual operations? Thanks!
Don't understand correctly? One is a heating medium and the other is a refrigerant. The temperature of the refrigerant medium cannot reach the temperature of the heating medium. Which formula is this? Take a look at the screenshot
