In the case of R744 refrigeration technology, system equipped with a two-phase ejector is one most efficient systems, allowing utilisation an R744-based unit in hot and tropical climates. However, experimental analyses ejector-based have only been performed for performance evaluation, mapping ejectors or validation numerical simulation. Therefore, main goal/scope this paper to enhance knowledge...

The efficiency of the ejector cycle is very sensitive to the ejector efficiency. This paper provides a literature review on ejector efficiencies in various ejector systems, such as vapor compression systems, solar driven ejector systems. The definitions of overall ejector efficiency and ejector component efficiencies in literature are summarized. The assumed constant ejector component efficienc...

The majority of integrated energy systems (IES) for combined electricity, heat and refrigeration generation, or trigeneration, are based on gas engines. fuel efficiency engines strictly influenced by intake air temperatures. Practically in all IES the absorption lithium-bromide chillers (ACh) applied conversing removed from engine into form chilled water. peculiarity trigeneration food industri...

Liquid recirculation is a method of improving evaporator performance by supplying the evaporator with more liquid than is evaporated. The excess liquid, which is generally provided by means of an externally-driven, mechanical pump, eliminates dryout and increases overall heat transfer coefficient in the evaporator. Liquid recirculation is common in large-scale industrial refrigeration systems, ...
