This paper presents the detailed laboratory experimental results of a low-temperature Organic Rankine Cycle (ORC) engine coupled with a Reverse Osmosis (RO) desalination unit. In a previous work, the identification of performance of the scroll type expander was presented. At that primary...

The current paper presents the economic evaluation of a two-stage Solar Organic Rankine Cycle (SORC) for using the mechanical energy produced during the thermodynamic process to drive a Reverse Osmosis (RO) desalination unit. The developed integrated system is briefly analysed and the specific...

Various Rankine cycle architectures for single fluids and other improved versions operating with ammonia/water mixture are presented in this paper. Untapped heat resources and their potential for driving organic Rankine cycles are outlined. The nature – state and temperature of the heat source...

The present work concerns the parametric study of an autonomous, two-stage solar organic Rankine cycle for RO desalination. The main goal of the current simulation is to estimate the efficiency, as well as to calculate the annual mechanical energy available for desalination in the considered...

An organic Rankine cycle (ORC) machine is similar to a conventional steam cycle energy conversion system, but uses an organic fluid such as refrigerants and hydrocarbons instead of water. In recent years, research was intensified on this device as it is being progressively adopted as premier...

Exergy analysis of micro-organic Rankine heat engines is performed to identify the most suitable engine for driving a small scale reverse osmosis desalination system. Three modified engines derived from simple Rankine engine using regeneration (incorporation of regenerator or feedliquid heaters)...

Steam traps are essential in the management of steam in industry. Various rating methods of steam-trap types make it difficult to evaluate their performance in a particular steam and condensate system. Table 1 shows steam-trap characteristics and operating conditions that have been rated so far....

Proper selection of a control scenario is essential for efficient management of energy systems which provide space heating and local ventilation to buildings. Using the steady-state, bottom-up approach, we have developed a mathematical model and the software AZMA to analyze the efficiency of...

A study has been carried out on heat recovery from air that ventilates a hot tool in a tool shop. The recovered heat is used to preheat air for space heating of this tool shop. Software has been used to analyze the heat-recovery efficiency and thermal comfort (TC) when the size and temperature...

We use a recovery heat exchanger (RHE) in an industrial building to heat incoming air for space heating by using the heat contents of some of the refuse hot-air flows (RAF). Several RAFs are often available with different flow rates and temperatures. A proper scenario for use of their heat...
