Abstract
In this work, the performance characteristics of heat exchangers were assessed and the influence of various factors on the weight and size characteristics of heat exchangers of power plants and complexes was determined. The patterns of influence of temperature pressures, properties of the working fluid, temperature levels of heat sources, operating characteristics of the cycle, heat transfer coefficients, heat transfer surface area, flow rate, heat capacity of the working substance, geometric and design parameters of heat exchangers on the performance characteristics of heat exchangers of low-temperature power plants have been established.
