A study has been carried-out on power density in the Proton Exchange Membrane Fuel Cell (PEMFC) for its application for solar power generation. It involves a fuel cell approach assisted with specific electro-catalysts to process special chemical coupling (2-propanol/acetone/H2) for generating...

A solar assisted absorption refrigeration system (SAARS) was designed for acclimatizing of villas in Mardin which is located in Turkey and the performance of the system under different temperatures was analyzed by using MATLAB. Hourly cooling load calculation of the villas was done between 15th...

An experimental investigation of a desalination system based on the HDH (humidification and dehumidification) of air is studied. The experiments were carried out in the premises of an open roof (six floors) of a Faculty of Engineering, Kafrelsheikh University, Egypt which lies at latitude...

This paper discusses the experimental validation of a theoretical model that determines the operating parameters of a DXSAHP (direct-expansion solar-assisted heat pump) applied to heating. For this application, the model took into account the variable condensing temperature, and it was developed...

This paper has shown the development of a theoretical model to determine the operating parameters and consumption of a domestic hot water (DHW) installation, which uses a direct-expansion solar assisted heat pump (DXSAHP) with refrigerant R-134a, a compressor with a rated capacity of 1.1kW and...

This paper considers different cooling systems and investigates the most promising alternatives when solar energy is to be used to supply the cooling demand. All the systems are evaluated during a summer cooling season by the energetic and economic point of view by dynamic simulation for two...

The present paper deals with a review of the nonuniformities present in compact heat exchangers in terms of temperature and flow and their effect on the performance of different energy transfer equipment. The understandings of flow distribution and flow pattern at the entrance of compact heat...

We designed a compound parabolic concentrator (CPC) with wings angled toward the east and west. Normally, solar collectors are straight, facing south, and the effective temperature is only achieved for a short period of time at midday. In the proposed design, the collector is divided into three...

In this paper we present a prototype for a new type of solar thermal collector designed for architectural integration. In this proposal, the conventional geometry of a flat solar thermal collector is changed to a curved geometry, to improve its visual impact when mounted on a building facade or...

Environmental awareness increases, with demands for environmental certifications of new communities and buildings as a result. In the district heating industry, enabling of decentralized energy production is one way to meet requirements from customers. In this paper the technical impact of...
