Experimental investigation on cool thermal storage integrated with chiller system for effective utilization of solar energy and building energy demand management

Abstract

In most of the developed countries, the increase in percentage share newlineof renewable power in the total power generation causes major concerns over newlinethe integration of the renewable power with the grid resulting in grid newlineinstability. Energy storage is a new frontier technology which is considered as newlinethe ultimate solution in developing a smart micro grid with distributed newlineRenewable Energy (RE) generation. Most of the tropical countries like India newlinespend nearly 24% of the electricity generated on air conditioning and food newlinepreservation. In such a scenario, among the various types of storage systems, newlinethe cool thermal storage plays a vital role in promoting renewable power in an newlineeconomical way. Considering the importance in the present increasing RE newlinescenario, in the present work, an experimental investigation was performed on newlinea cool water storage integrated with a chiller system driven by a solar PV unit newlinewhich has certain decisive advantages in central air conditioning system for newlinedemand management strategies and to solve the grid instability. Further, in this work, an experimental investigation was performed on a packed bed cool storage system integrated with a chiller system which has major advantages in central air conditioning system for demand management strategies. The storage system consists of encapsulated spherical newlineballs filled with a mixture of distilled water and pseudomonas (nucleating newlineagent) as phase change material and a mixture of distilled water and newlineMono-ethylene glycol as the heat transfer fluid. newline newline
