A cold storage air-conditioning system was built to investigate the energy saving effect of using tetrabutylammonium bromide (TBAB) clathrate hydrate slurry (CHS) as cold storage medium; the corresponding COP during TBAB CHS generation and the pumping power during the cold release were measured. As the increase of the TBAB CHS mass fraction during the generation; the system COP generally decreased from about 1.92-2.95 to about 1.05-1.49; depending on TBAB CHS flow rate. To clarify the performance of this system; several cold storage strategy cases are studied; the corresponding electric power consumption and the cost saving; compared with water as the cold transportation medium; are shown in this work as well.
