Battery thermal management (BTM) is crucial for the lifespan and safety of batteries. Refrigerant cooling a novel technique that being used gradually. As core fluid refrigerant cooling, refrigerants need to possess excellent properties while meeting environmental requirements. This paper elucidates current state (single mixed refrigerants), synchronously summarizing them from perspectives (immersion cold plate indirect). It outlines advantages disadvantages single as well research development in vehicle system (TMS). The choice directly affects performance, on air conditioning (AC) systems can indirectly guide BTM. R1234yf R152a replace R134a, although R744 has strong heating capacity, it cannot R134a. Specific reduce global warming potential (GWP) flammability issues, thereby improving efficiency. Additionally, immersion controls temperature through container pressure. Coordinated control strategies are indirect offering broad prospects optimizing design intelligent control. selection optimal method greatly improve performance battery. may promote good

Experimental study on the impact of indoor unit airflow velocity on the performance of an automotive heat pump system with a suction line heat exchanger

Heliyon, Год журнала: 2024, Номер 10(17), С. e36719 - e36719

This study aimed to investigate the effect of changing indoor unit air flow rate on performance an automobile heat pump with a suction line exchanger. Using four-way valve, automotive system was developed by reversing refrigerant direction in conditioning system, excluding compressor. A exchanger added test enhance transfer between liquid and lines system. Performance comparisons were first performed for R134a R1234yf disabling Then, activated R1234yf, tests repeated. made two different compressor speeds three airflow speeds. It found that using operations improved heating capacity, discharge temperature coefficient approximately 1.8 %, 5.1 % 5.9 respectively. The capacity R134a, determined be range 2.46–3.29 kW, 2.35–3.04 2.39–3.11 An increase speed from 1.4 m s−1 3.2 resulted average decrease 12.3 temperature. In contrast, increased 11.8 14.4 average, respectively, revealed optimizing exchanger, improvements can achieved, thus providing better thermal comfort passenger compartment.

The control strategy of the thermal management system is crucial for ensuring comfort an electric vehicles (EVs) cabin. However, performance heat pump air conditioning (HPAC) significantly deteriorates in low‐temperature weather conditions. In recent years, CO 2 HPAC has emerged as a potential solution to address insufficient heating capacity such environments. order ensure cabin and optimize winter mileage, three‐stage method source (ASHP) proposed this article. Firstly, simulation model established its feasibility verified by comparing it with experimental results. Subsequently, cabin's examined under four different conditions (–5, −10, −15, −20 °C). Optimal opening closing strategies each mode are discussed maintaining temperature requirements demonstrates improvements battery state charge over 7200 s running time compared conventional ASHP: optimization rates increase 8.07% at −5 °C, further 10.03% −10 substantial 14.51% −15 extreme rate high 16.21%.
