Numerical investigation On Vertical Generator integrated with phase change materials In Vapour Absorption Refrigeration System A.Ponshanmugakumar1,a*,S.Badrinarayanan2, P.Deepak2, H.Sivaraman2 and R.Vignesh Kumar2 1AMET University, Chennai 2Department of Mechanical Engineering, Sri Sairam Institute of Technology ashnmgkmr8@gmail.com Keywords: TRNSYS, LiBr-H2O, Vapour absorption machine (VAM), phase change materials (PCM), Erithritol, Storage tank, Numerical simulation.
For latent heat thermal storage the optimal phase change material is selected as Erithritol in the PCM containment.
By using phase change materials in the storage tank the auxiliary heating source demand can be decreased at the peak load time or in the low radiation period.

At present, the calcium silicate products industry as a whole is lag behind developed countries, and poorly equipped, low content of science and technology, single technology, product performance is not stable and so on.
Experiment Experiment materials Calcareous material: the calcareous material for quick lime used, the limestone under 1000 ℃ calcination.
Experiment Results and Discussion Effect of stirring technology on properties of calcium silicate insulation materials Dynamic hydrothermal method as opposed to the static method, namely stirring the slurry constantly under the conditions of high temperature and high pressure, and the solid particles suspended in a solution, ensures the reaction between materials.
Effect of fiber adding process on the performance of calcium silicate insulation material Admixture Follow-up process Siliceous materials Carbon fiber Mixed Calcareous material Water Pressing Slurry Dynamic hydrothermal reaction Fig. 2.2 The fiber and concrete mixing process Compact structure of carbon fiber causes the existence of molecular forcestrong its intermolecular, the carbon fiber in the matrix is extremely easy to wound and reunion, the formation of local structural defects could not improve the role but greatly reduce the comprehensive properties of the materials.

Introduction Phase change materials (PCMs) can store and release energy during phase change processes [1,2].
Microencapsulated phase change materials (MPCMs) not only have the ability of phase change from solid-liquid to presolid-solid in the meantime avoiding the influence of outside moisture, oxygen and other factors, but also can improve the stability of phase change materials.
