Thermodynamic analysis of a modified vapor-injection heat pump cycle using an ejector

Yang Zhao et al.

Summary: This paper presents a modified sub-cooler vapor-injection (MSV) cycle with an ejector to improve the performance of air source heat pump applications. Through the introduction of the ejector, the MSV cycle achieves two condensation temperatures and exhibits higher heating coefficient of performance (COPh), volumetric heating capacity, and exergy efficiency compared to a basic sub-cooler vapor-injection (BSV) cycle. The evaluation results also suggest that R1234ze(E) is the most promising refrigerant for replacing R134a in the MSV cycle.

Performance evaluation of the solar-driven multi-ejector refrigeration cycle without an auxiliary heat source

Javid Beyrami et al.

Summary: This paper proposes a novel solar-driven multi-ejector refrigeration system with internal heat exchanger, regenerator, and storage tank, aiming to eliminate the need for an auxiliary heat source and cooling system. Numerical and computational fluid dynamics models are developed to evaluate the performance, optimize design parameters, and analyze sensitivity. Results show that the proposed system can provide the required cooling load more efficiently than conventional systems.

Performance analysis of a dual temperature heat pump based on ejector-vapor compression cycle

Jian Liu et al.

Summary: A novel dual temperature air-source heat pump system based on ejector-vapor compression cycle outperforms the conventional system in terms of performance, showing significant improvements in COPh, q(v), and eta(II), especially under typical operating conditions. R290 exhibits the best performance among the various refrigerants. The NDAHP system performance is more sensitive to the evaporating temperature than the condensing temperature, and the eta(II) is significantly affected by the high-temperature heating load ratio (LR), increasing with the LR.
