Design and Modification of Air Dehumidifier: A Review
Abstract: Abstract Air dehumidifier can be designed and modeled working on the simple principle of dehumidification of compressed air by means of collision with the number of cylinders arranged in series. This dehumidifier does not require any hygroscopic media or absorptive media such as activated alumina, silica gel, salt tablets, etc., which are used in other dehumidifiers. It does not require any refrigerant which is used in the refrigerated dehumidifier. The …

Absorption Refrigeration System through Solar Energy: An Over Review
Abstract: Abstract Recently, types of traditional energy have failed to satisfy the human needs due to their limited quantity as well as their negative environmental impacts. Conventional refrigeration systems mainly based on vapor compression system are major electricity consumers and their refrigerants are being banned by international legislation. It was studied that out of the total energy consumption, a large portion of energy is being used by conventional refrigeration systems. From …

Experimental Analysis of Capillary Tube in a Vapor Compression Refrigeration System
Abstract: Abstract A capillary is an essential deice of a vapor compression refrigeration system. It is used to reduce the condenser pressure to evaporator pressure. The refrigerant is expanded enthalpically, the reduction in pressure also reduces corresponding saturation temperature. This paper presents the analysis of expansion device accounting for three different sizes of capillary tubes. The investigations are carried out for different length of capillaries measuring 3, 3.5 and 4 m …

Experimental Analysis of a Novel Parabolic Trough Receiver for Direct Steam Generation
Abstract: Abstract In this paper, experimental study of a parabolic trough collector and novel receiver with concentric tubes (C-PTR) for direct steam generation is presented. The performance of the C-PTR system is extensively studied by varying the parameters such as the direct normal irradiance, the mass flow rate, the type of circulation and the amount of phase change material (PCM). The maximum thermal efficiency achieved using C-PTR is averaged about 58% …

A Review: Hybrid Air-Conditioning System
Abstract: Abstract Science is universal but technology depends upon local conditions. The world is facing on a large scale, potentially devastating global energy crisis. It has been realized that traditional resource such as oil and gas energy reservoirs cannot meet the rising energy demand. Integrated design is one of the today’s buzzwords in green and sustainable HVAC design approaches and solutions; that are important for achieving good indoor air quality with …
