Abstract

A calculation and optimization algorithm is proposed for operating modes of composite parabolic trough mirror-concentrating sysetms (MCSs) with allowance for the geometric and optical parameters of the concentrator heat receiver in a wide range of operating conditions, as well as temperature conditions of the system as a whole. The thermal and exergy efficiency (i.e., the reversible thermal Carnot cycle) are estimated, the values of which for the developed linear composite parabolic trough concentrators are 0.4438 and 0.0932, respectively.
