Abstract

Objectives: This review explores the rationale of using waste heat energy from hot exhaust gases, hot water & hot steam to improve efficiency of systems. Methods: Since the amount of non-renewable sources is limited, there is unmet need to develop systems which utilize nonrenewable sources or waste energy (reusable) sources. Energy recovery systems (i.e. heat pumps & exchangers) of waste-to-energy units represent a substantial part which utilizes waste energy to increase thermal as well as electric power of whole system. Findings: Waste water can be considered as a reusable key energy source. Because of the higher thermal efficiency, combined cycle power plants are striking options based on this technology for generation of power as compared to individual gas or steam turbine cycles. Along these lines, the ideal outline of such cycles is of incredible noteworthiness inferable from expanding fuel costs and diminishing fossil fuel assets. Improvements: As a consequence, cost of product can be optimized and environment can also be protected.

Abstract

Objective: The purpose of this review leads to use of Energy conservation technologies. Methods: There are so many systems which are used for energy saving among them thermal storage system with Phase Change Material (PCM) is well known. In this review majority focuses on the human comforts. It was observed that maintaining the human comfort is the challenging task for living spaces like room, offices etc. such type of required energy which is satisfied by thermal storage PCM based system. If the Phase change materials are applied to building applications they can be used for peak load shifting in cool storage system. Findings: Development of the new techniques for getting thermal comfort for building (lowering the heating and cooling demand is required. Also it includes the expenses behind development, maintenance and installation. Moreover this review finds the effective phase change materials. Improvements: Such thermal storage system has a potential to replace the conventional methods but the effectiveness or efficiency of that system is less. So it is required improvement in the selection of thermal storage system and phase change material. Also this review presents the potential of the phase change material system.
