Summary

This study examines the cool storage performance of the R1234yf hydrate system via an integrated experimental and simulation approach. Experimental results show that the system’s cool storage performance is improved at elevated charging pressures or reduced initial water temperatures. At the maximum charging pressure of 260 kPa and the minimum initial water temperature of 19 ◦C, the system attained optimal performance, with the total cool storage capacity reaching a maximum of 883 kJ and the average cool storage rate peaking at 0.44 kW.
Simulations conducted under the above optimal conditions indicated that an increase in compressor suction superheat from 2 K to 10 K improved the system coefficient of performance (COP) by 2 % and the cool storage capacity by 5 %. An increase in condenser outlet subcooling from 1 K to 5 K led to a 4 % improvement in the system COP and a 42 % rise in the cool storage capacity. Elevating the isentropic efficiency of the compressor from 0.65 to 0.85 enhanced the system COP by 19 %, while the cool storage capacity remained unchanged.
