Eliminating or Handling Very Close Temperature Approach in Sizing a Heat Exchanger

A close temperature (and sometimes zero degree temperature) approach in a heat exchanger is desired in many industrial applications because it provides maximum heat transfer. When a heat exchanger is sized for a very close temperature approach case, it results in an extremely large heat transfer surface area, costing a client a lot of additional money and extra floor space—this article presents a solution to this dilemma.
