Abstract

To address the inherent problems of high driving energy consumption and low heat exchange efficiency during the seasonal operation of existing energy storage systems driven by water pumps in charging and discharging processes

a novel two-phase passive cold energy storage system is proposed. An experimental platform is constructed to measure the temperature and pressure distributions under different filling rates and cold source temperatures with R22 and R410A as working fluids. The effects on the system start-up characteristics and thermal performance are analyzed

and the temperature distribution characteristics within the cold energy storage body are obtained. The results show that the temperature of the system loop decreases with the decrease of the cold source temperature. When the cold source temperature decreases from -2 ℃ to -12 ℃

the outlet temperatures of the condenser for R22 and R410A decrease by 10.6 ℃ and 7.1 ℃

respectively; The filling rate exerts a significant influence on the circulation of the working fluid. Within the experimental range

the minimum cold energy transfer resistances of R22 and R410A are 0.090 ℃/W and 0.097 ℃/W

which occur at filling rates of 50% and 70%

respectively; After 14 days of operation

the overall temperature of the water tank remains below 3.8 ℃

demonstrating a favorable cold energy storage performance. This study provides a theoretical basis for the further optimal design and application research of passive cold energy storage systems.
