Modeling of the plate heat exchangers in the double-circuit water-supply system
This paper consideres the water-supply systems with a natural cooling. The advantages and disadvantages of the single- and double-circuit water-supply systems are revealed. The analysis of the plate heat exchangers revealed that thermal pollutions in open circuit is much higher than pollutions a closed circuit. It allowed to set up heat transfer equations for the plate heat exchangers and a mathematical model of the heat pollutions increase in open circuit water-supply systems. An accuracy of a modeling allowed to use this model for water-supply system optimization.
