Heat exchanger effectiveness is a measure of a heat exchanger's ability to transfer heat relative to its maximum possible heat transfer capability. It is defined as the ratio of the actual heat transfer to the maximum heat transfer that could occur under ideal conditions, providing insights into the efficiency of the heat exchanger's performance. Understanding this concept is essential, as it relates directly to how well heat exchangers operate in practice, factoring in parameters like overall heat transfer coefficients and how fouling can affect performance.
