6 FAQs about [Energy storage method of ejection system]

What is a simple ejector refrigeration cycle?

A simple ejector refrigeration cycle was used for the cascade refrigeration system and examined experimentally and conceptually . The system was tested under diverse operating conditions and high evaporation temperatures.

How to optimize ejector performance?

A reduced area ratio with high critical pressure is desired to achieve optimal ejector performance. The shock positions of the mixed stream inside the mixing section are highly important in analyzing the ejector's performance.

Can a high efficiency geometry ejector be used in refrigeration applications?

Gutierrez A, Léon N (2014) Conceptual development and CFD evaluation of a high efficiency–variable geometry ejector for use in refrigeration applications. Energy Procedia 57:2544–2553 Worall M (2001), An investigation of a jet-pump (ice) storage system powered by low-grade heat, PhD thesis, University of Nottingham.

Can ejector refrigeration be used for turbine inlet air cooling?

Al-Ansary HA (2007), The use of ejector refrigeration systems for turbine inlet air cooling: a thermodynamic and CFD study. In Energy sustainability (Vol. 47977, pp. 231–238). Petrenko VO, Huang BJ and Shestopalov KO (2011). Innovative solar and waste heat driven ejector air conditioners and chillers.

How a gas turbine ejector is used to achieve low pressure?

To obtain low pressure, the ejectors can be connected in series. The ejector was used to improve the performance of the gas turbine in a similar way to how it was used to improve the automobile performance. This example used flue gases as the motive flow to trigger the supersonic ejector.

How do multiple nozzles improve the ejector system performance?

In this study, multiple nozzles are positioned at the mixing section inlet to improve the ejector system performance . To create a vacuum effect, the ejector system's secondary flow is reduced or blocked. The nozzle jets generate a suction zone at the intake of the mixing section in this example [191, 192].
