摘要

The applicability of mathematical models having different degrees of approximation for describing countercurrent heat exchangers with single-phase heat carriers is discussed. Instead of an iterative procedure, an analytical method for calculating frequency characteristics is proposed that is based on the condition of the absolute invariance of the inlet temperature of an external heat carrier. Examples of calculating the characteristics of the countercurrent economizer of a TGMP-344A boiler are given.
