Abstract: Naval surface ships should use thermally driven heating and cooling technologies to continue the Navy’s leadership role in protecting the marine environment. Steam ejector refrigeration (SER) or steam ejector heat pump (SEHP) systems are thermally driven heating and cooling technologies and seem to be a promising technology to reduce emissions for heating and cooling on board naval su...

The fuel efficiency of cooling air at the inlet marine low speed diesel engine with water-fuel emulsion combustion by ejector chiller utilizing heat exhaust gas along route line Mariupol– Amsterdam–Mariupol was estimated. values available refrigeration capacity chiller, intake temperature drop and corresponding decrease in specific consumption main varying climatic conditions were evaluated. Th...

Two-phase ejectors have been gaining increased attention in recent years due to their ability to directly improve the COP of the cycle. Of common interest in two-phase ejector studies is how the ejector improves cycle COP. However, less emphasis is often given to the performance of the two-phase ejector itself. The amount of COP improvement offered by an ejector cycle is very strongly influence...

Low temperature cold chain is the top priority of logistics development at this stage. CO2 (carbon dioxide) refrigeration system widely used. However, low efficiency biggest obstacle to its development. In research work, EES (Engineering equation solver) used simulate system, which in thermodynamic modeling and calculation, a novel trans-critical cycle with ejector for low-temperature storage p...
