ΟΛΟΚΛΗΡΩΜΕΝΟΣ ΣΧΕΔΙΑΣΜΟΣ ΔΙΚΤΥΩΝ ΕΝΑΛΛΑΓΗΣ ΘΕΡΜΟΤΗΤΑΣ
… WAY TO INTEGRATE INDUSTRIAL HEAT LOADS. THE "PINCH POINT METHOD" (B. LINNHOFF 1978-1982) APPROACHES THE PROBLEM USING THERMODYNAMICS AND THEN IT USES THE EXPERIENCE OF THE DESIGN ENGINEER TO CHOOSE AND CALIBRATE THE FINAL NETWORK. THE NEW ALGORITHM IS BASED ON THE FOLLOWING NEW ARGUMENTS: THE …

Saturation curve analysis of humidification-dehumidification desalination systems and analysis of reversible ejector performance
… to graphically understand these limits. A pinch point methodology is employed to evaluate the impact of heat and mass exchanger size upon performance. The impact of salinity upon the design methodology is described. As the pinch point temperature and concentration differences decrease, the …

Regeneration through decay: Architectural prosthetic within the damaged coastline of the South African West Coast
… of the last most important portion (the pinch point). This landscape lends itself as a testing ground for an architectural investigation acting as a tool to stabalise the pinch point, rehabilitate ecology and serve as resistance for any future exploitation. Using the Japanese practice of …

Humidification Processes in Gas Turbine Cycles
… been experimentally determined to 1.6% and the pinch-point to 0.1°C. The reconstruction of the pilot plant from a simple cycle to an evaporative cycle has resulted in an increase in thermal efficiency from 21% to 35%. A theoretical model has been developed for the humidification process that …

Sea + Survival: choreographing dune systems to defend against sea-level rise
… lands itself, in the investigation of the pinch-point between human and nature; the human treatment of the coastal 'dunescape', and the ecosystem services of coastal dunes amid a climate crisis. Due to the constrained nature of the coast, sea defences are required to take place offshore, …

The Investigation of Aspects of Chemical Looping Combustion in Fluidised Beds
… heat is released at temperatures well above the pinch point; (3) since the temperatures of heat source in this research is well above the pinch point, all heat are usable for the steam cycle. In this case, the steam cycle and the chemical looping plant could be optimised separately; (4) As long …

Low temperature glide cycles for energy storage applications: Thermodynamic and capital cost analysis
… high variability, which would incur substantial pinch-point problems and thus inefficiency in the heat transfer processes integral to PTES. In the present work, an alkane mixture is therefore optimised to achieve near-constant heat capacity. This alkane mixture is then used as the working fluid …

Thermodynamic Analysis and Optimization of Supercritical Carbon Dioxide Brayton Cycles
… and without being trapped in local optimum points. Two optimization schemes, i.e. single-objective and multi-objective, are considered in optimizing the S-CO2 cycles for high temperature solar tower applications. In order to reduce the size and cost of solar block, the global maximum …
