چکیده

• Ejector enhanced PV/T air dual-source heat pump is presented. Optimum evaporation temperature determined. The COP of the can be improved by 22.6% when 15 m 2 collector used. Consumed electricity from grid for heating reduced 75% Dual-source unit utilize refrigerant at two different pressures. By adopting an ejector, high-pressure stream used to lift compressor inlet pressure which results in a higher coefficient performance (COP). This study proposes renewable energy sourced and high-efficiency system easily building integrated offer solution. devised on complementation dual thermal sources; one other solar, maximize utilization ambient highly efficient operation pump. Using advantage relatively lower operating solar line, efficiency would sufficient winter. Adaptation photovoltaics as unit, will benefit produced further reduction demand grid. Along with use collector, potentially carbon neutral larger areas. In this study, improvement potential dual-sourced ejector booster investigated locations Turkey presents weather profiles. optimum temperatures are determined, potentials discussed conditions. For supply 5 kW, under 400 W/m 10°C using collector. Including generated PV, reach same

Performance analysis of a novel dual-nozzle ejector enhanced cycle for solar assisted air-source heat pump systems

In this study, a novel dual-nozzle ejector enhanced vapor-compression cycle (DEVC) for solar assisted airsource heat pump systems is proposed. In DEVC, the use of the dual-nozzle ejector for recovering the expansion losses is a very promising approach to improve the cycle performance. A mathematical model of the DEVC is developed to predict its performance under specified operating conditions. ...
