We have considered the general case of a collector with four reflectors. An analytical model is developed for study of the effect of an individual reflector on the collector. Reflectors R-1, R-2, R-3, and R-4 face south, north, west, and east, respectively. For a collector with two reflectors...

In this paper, the design of a triangular built-in storage-type solar water heater with transparent insulation on the top and sides is studied under various operating conditions. The transient performance of the system is studied by using a finite-difference forward time-step marching technique....

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 article, we use the concept of artificial neural network and goal oriented design to propose a computer design tool that can help the designer to evaluate any aspect of earth-to-air heat exchanger and behavior of the final configuration. The present study focuses mostly on those aspects...

This is the first part of a set of two papers, about the estimation of solar irradiance on the absorber plate and cover of a semi-cylindrical solar tunnel dryer (STD). The second part discusses the modelling and thermal performance results of the STD. A detailed analysis has been carried out in...
