چکیده
A comparative analysis of the methods approximate thermal calculation superheated steam condenser compression heat pump supply system is presented. The working substance and condensing refrigerant R410a. When single-zone method applied, calculated by one area with inclusion overheating in condensation use coefficient. two-zone assumes two separate areas, viz. cooling its actual condensation. approbation was carried out during a numerical study low-temperature for heating hot water supply, exchange surface form spiral coil pipe immersed heated liquid. In first approach, flow rate temperature are limited saturation refrigerant, regardless pattern media. counter-current or cross-counter-current scheme media makes it possible to obtain real results that exceeds saturated vapor, taking into account water. this case, wall higher than temperature, lower, which further confirms adequacy presented technique. technique averaging physical properties areas cooling, as well pressures, provides more accurate value surface, case under consideration reduced 20%. Based on conducted studies, recommended reliable data parameters condenser.

Improvement of Efficiency of Coal-Fired Steam Power Plant by Reducing Heat Rejection Temperature at Condenser Using Kalina Cycle
This paper proposes an approach for improving the plant efficiency by reducing the heat rejection temperature of power cycle using Kalina Cycle System 11 (KCS11) which is integrated at the steam condenser of a 500 MWe SubC (subcritical) coal-fired power plant. It is modelled by using power plant simulation software ‘Cycle Tempo’ at different plant operating conditions. Results show t...
