| الوصف: | As renewable energy sources experience rapid growth and widespread adoption worldwide, the pressing challenge lies in efficiently storing and utilizing them. The Carnot battery emerges as a promising solution to this challenge. Existing Carnot batteries based on the Organic Rankine Cycle (ORC) mainly focus on district heating and power generation applications but neglect the unique operational conditions found on farms. This study investigates a family farm in Nigeria. Due to the intermittent nature of the national grid, the family relies on diesel generators as a backup power source, thus prompting consideration of renewable energy sources for environmental and energy-saving purposes. Therefore, an off-grid reversible heat pump (HP) /ORC with a photovoltaic (PV) array must be designed to meet the electricity and cooling needs of the farm. The configuration and working fluid of the reversible HP/ORC system are first selected, and then the pinch point and glides of heat exchangers, the top temperature of hot storage, and the built-in volume ratio of the scroll machine are determined. The results give the round-trip efficiency and operating mode details in various demand coverage throughout the year in addition to the COP of HP, and ORC efficiency at nominal conditions. The design with an electrical heater and ice-cooled ORC is proposed to improve system performance and its COP and ORC efficiency can reach 2.72 and 9.51%, respectively.
