This　study　conducted　experiments　to　compare　the　desalination　efficiency　of　gravity　and　centrifugal　desalination　methods　for　freezing　desalination,　showing　the　superiority　of　centrifugal　desalination.　Moreover,　through　experiments　on　supercooled　water　production,　it　was　determined　that　supercooled　water　can　operate　stably　at　an　evaporator　temperature　of　−4.5　°C,　and　its　supercooling　state　can　be　released　using　ultrasound.　Based　on　the　experimental　results,　a　novel　system　that　combines　freezing　desalination　with　ice　storage　is　proposed.　The　proposed　system　utilizes　supercooled　water　for　ice　production　and　centrifugal　post-treatment,　using　desalinated　ice　as　a　cold　storage　medium　to　integrate　desalination　and　ice　storage.　The　proposed　system　showed　a　30　%　lower　total　capital　cost　compared　to　conventional　systems,　with　a　payback　period　of　38.18　%　lower　than　conventional　system　(5.42　years).　Additionally,　the　system　demonstrated　optimal　economic　performance　when　utilizing　80　%　of　its　ice　storage　capacity,　with　a　payback　period　of　3.38　years,　contrasting　with　7.62　years　when　utilizing　20　%　storage　capacity.　The　application　of　this　system　in　four　regions　with　varying　peak　and　off-peak　electricity　prices,　including　Guangdong,　Fujian,　Hainan,　and,　France　revealed　that　the　system　demonstrates　greater　economic　viability　in　areas　with　significant　disparities　in　electricity　pricing.　©　2024　Elsevier　Ltd
