Refrigerant and the Environment- issues and planning for the future-A study
Abstract: Abstract However, the halogenated refrigerants have undesirable environmental impacts such as ozone layer depletion potential and global warming. Hence, it is necessary to go for alternative refrigerants to satisfy the objectives of the international protocols. Future international commitments on the protection of the environment, particularly for reducing greenhouse gas emissions and better protection of the ozone layer by use of other suitably refrigerants. In this context, the use of "natural" …

Performance Evaluation of Thermoacoustic Refrigeration System
Abstract: Today cooling technologies are going through a transformation phase. The advent of ozone layer depletion and global warming caused by the use of synthetic refrigerants has necessitated a search for alternative cooling technologies. Out of the several technologies which are emerging as alternatives, one technology that can provide cost effective refrigeration without using any of the environment degrading refrigerants is the thermoacoustic refrigeration system. Ideally, this device can be powered …

PERFORMANCE AND EMISSION ANALYSIS OF RAPESEED METHYL ESTER BLENDS AS ALTERNATE FUEL FOR DIESEL ENGINE APPLICATIONS
Abstract: Air pollution at sea is due to exhaust emissions from the marine diesel engines of cargo ships, tugs, passenger and patrolling vessels, and motorboats. The emissions from marine engines cause human health hazards like cancer in the lungs, cardio problems, effects the healthy environment, ozone layer depletion and global warming. Rapeseed methyl ester (RME) blends with diesel fuel is one of the best alternate fuels to reduce the exhaust emissions …

Vehicle Hybridization: Concept of future car engine by fuel – compressed air combination.
Abstract: Nowadays, Vehicle’s exhaust product is one of the sources of environmental problems in India. Their products of combustion are causing the greenhouse effect, depletion of Ozone layer, etc. On the other hand, a case study research on fossil fuel in the year 2004, predicts that if the oil is consumed at the current rates, 80% of the entire available resource will be consumed very soon. So now we need to …

Urban Planning Mitigation Trajectories for Urban Heat Island (UHI) A Case Study of Guntur, Andhra Pradesh, India
Abstract: AbstractGlobal radiation related solair-temperature directly influences Urban Heat Islands (UHI) as the built environments and surrounding atmosphere cause increase in urban solair temperatures, the resulting temperature completely depends on the thermal properties of the exposed materials. Urban heat islands can lead to deterioration of flora and fauna, elevation of ground level ozone, health disorders and increase in building energy consumptions. The study area of Guntur region which is susceptible to …
