A novel passive space conditioning configuration is presented, integrating a Solar Collector System, Underground Storage Tank and Novel Heat Exchanger. This Underground Solar Thermal Heat Exchanger (USTHE) provided improved sensible heating/cooling of air by employing a Novel Heat Exchanger...

In this paper, an artificial neural network (ANN) model is developed for estimating beam solar radiation. Introducing a newly defined parameter, known as reference clearness index (RCI), computation of monthly mean daily beam solar radiation at normal incidence has been carried out. This RCI is...

This communication presents a second law analysis based on an exergy concept for a solar thermal power system. Basic energy and exergy analysis for the system components (viz. parabolic trough collector/receiver and Rankine heat engine, etc.) are carried out for evaluating the respective losses...

The energy and exergy analysis has been carried out for the different components of a proposed conceptual direct steam generation (DSG) solar–thermal power plant (STPP). It has been found that the maximum energy loss is in the condenser followed by solar collector field. The maximum exergy...

This article presents an overview on the research and development and application aspects for the hybrid photovoltaic/thermal (PV/T) collector systems. A major research and development work on the photovoltaic/thermal (PVT) hybrid technology has been done since last 30 years. Different types of...

Desalinated water, the final product of a solar distillation system, is useful for drinking purpose, community services, industry and agriculture on a small scale. It is expensive and may be considered as an industrial product. In the present communication, it has been tried to collect...

An analysis is presented for the performance of an inexpensive sand collector for solar energy which has been validated experimentally. The collector consists of a plane network of polythene pipes buried in a sand mass which is kept in a wooden case, the top surface of the sand being fixed by...

This paper describes an investigation of the periodic heat transfer and optimum placement of the air gap in a hollow concrete slab subjected to solar radiation and atmospheric air on one side and in contact with air at a fixed temperature on the other. The heat conduction equation has been...

In this paper, artificial neural network (ANN) models are developed for estimating monthly mean hourly and daily diffuse solar radiation. Solar radiation data from 10 Indian stations, having different climatic conditions, all over India have been used for training and testing the ANN model. The...

The conventional expression for the coefficient of performance (COP) of an ideal absorption cycle is misleading and a correct expression is derived. The deviation in the COP values from these two expressions increases with the increase in the difference in the absorber and condenser temperatures.
