Reduction of the supercooling of Ca(NO3)2•4H2O using electric field and nucleating agent effects

Experimental investigation on nucleating agent for low temperature binary eutectic salt hydrate phase change material

“…Degree of supercooling also influences the heat storage efficiency of the PCMs, and it is very important to nullify or minimise the supercooling effect to extract TES. [5], BaI2.6H2O and SrCl2.6H2O as nucleating agent with calcium chloride hexahydrate [6], TiO2 as nucleating agent for sodium sulphate decahydrate [7], BaCO3 as nucleating agent for calcium nitrate tetrahydrate [8], sodium dihydrogen phosphate dehydrate as nucleating agent for sodium acetate trihydrate as PCM [9], ZnO and Zn(OH)2 as nucleating agent with zinc nitrate hexahydrate as PCM [10]. The goal of this experimental research study is to develop a binary eutectic salt hydrate phase change material (PCM) with improved thermal performance for building thermal regulation by employing sodium carbonate dehydrate (SCD) and sodium phosphate dibasic dodecahydrate (SPDD).…”

“…Few super nucleating agents and salt hydrate PCM are discussed. SrCO3 and Sr(OH)2 as nucleating agent with magnesium chloride hexahydrate as PCM[5], BaI2.6H2O and SrCl2.6H2O as nucleating agent with calcium chloride hexahydrate[6], TiO2 as nucleating agent for sodium sulphate decahydrate[7], BaCO3 as nucleating agent for calcium nitrate tetrahydrate[8], sodium dihydrogen phosphate dehydrate as nucleating agent for sodium acetate trihydrate as PCM[9], ZnO and Zn(OH)2 as nucleating agent with zinc nitrate hexahydrate as PCM[10]. Though many research works are conducted with different nucleating agent for salt hydrate PCMs, nevertheless as in this research work a new binary eutectic PCM is reported, it is vital to…”

Study on preparation and thermal properties of new inorganic eutectic binary composite phase change materials

“…When mixed with 0.08% Na 4 P 2 O 7 ·10H 2 O (TSPP) nucleating agent and 2% sodium polyacrylate (PAAS) thickener, the phase change material has good cycling stability and can be subcooled to 3.6 °C. Putri et al 18 selected 12 nucleating agents, by adding 1 wt% of each nucleating agent to the solution, the enhancement impact of each nucleating agent on the supercooling of Ca(NO 3 ) 2 ·4H 2 O was ascertained. The findings demonstrated that BaCO 3 was the most effective and appropriate nucleating agent for Ca(NO 3 ) 2 ·4H 2 O.…”
