What Is Heat Exchanger Effectiveness ?

The term efficiency of heat exchanger is not defined as a unique concept in scientific resources. However We are happy to answer any questions you might have about heat exchangers from the SA179tubes.com team of experts.proximity of the system to that state is defined as efficiency. In the case of a heat exchanger, the ideal state is not definitively determined. But methods are provided for this purpose A heat exchanger's effectiveness can be measured by calculating its performance. Heat exchanger effectiveness is defined as the ratio of actual heat transfer to attainable heat transfer in an infinitely long counterflow exchanger. As a result, we select an infinitely long exchanger since it will allow for the maximum amount of heat transfer (i.e. Eventually, enough heat will be transferred so that the driving force will disappear - both streams will reach the same temperature).

To understand the rationale behind the choice of a counterflow exchanger (in this definition), it is instructive to look at both cases: an infinitely long parallel exchanger and one an infinitely long counterflow exchanger Plate heat exchangers are efficient heat recovery units used in a variety of commercial, industrial and residential settings. By extracting sensible energy from exhaust air and using it to cool or heat incoming air, a plate heat exchanger can significantly reduce a building's energy costs and environmental impact.
