Краткое описание

We present a new "energy-cost-characteristic" diagram (CAREC) for optimising heat exchangers. It is based on the monetary cost and the total consumption of primary energy (energetic cost). This diagram gives the characteristics of the exchanger which corresponds either to the minimum monetary cost or the minimum energetic cost and also the extra-monetary cost required to pass from the first optimum to the second.
The use of the CAREC is demonstrated for the case of a boiler water feed pre-heater and a standard shell and tube heat exchanger.
