Multipurpose Desert Cooler: A Diagnostic Approach to Enhance the Performance
Abstract: India being a tropical country has high temperature and humidity during summer. It is expensive to maintain comfort conditions through air-conditioning devices; however, scarcity of electricity is another problem. Therefore, desert coolers are being used in most of the areas of the country, which consume comparatively less amount of electricity. However, it is not fully efficient for the humidity as well as for cooling. This paper describes the methods of …

Exergy Analysis of Vapor Compression Refrigeration System with Refrigerants R134a, R152a, R290 and R32
Abstract: Abstract This paper pressents exergy analysis of vapour compression refrigeration system with refrigerants R134a, R152a, R290and R32. This analysis helps to understand the effect of irreversibility on thermodynamic processes. It shows exergy losses in different components of the system and hence leads to improve the performance of different components of the system. A computational model has been developed to study the effects of evaporator temperature and condenser temperature on COP, …

VRGE Process an Alternative for Conventional Hydraulic Fracturing
Abstract: Abstract Hydraulic Fracture is the name frequently heard now a day in oil and gas Industry especially in exploiting shale gas Reserves. Hydraulic fracturing fluid is made up of water, sand, and chemicals. In this process a high-pressure fluid (usually chemicals and sand suspended in water) will be pumped with high pressure into the oil and gas bearing zone where it create fractures and increase the permeability of the formation. …

Solar Humidity Control Unit with Hot Water Generation
Abstract: Abstract Our country lying in tropical region predominantly has high humidity in air in nearly three-fourth span of a year. Maintaining indoor comfort conditions in these conditions become expensive. This paper presents the design of an all-in-one solar-powered humidity control unit which will also provide hot water in the building. The configuration consists of indoor and outdoor units provided with evaporative coolers and desiccant units. The outdoor unit is coupled …
