Solar air heater applications in India
Renewable Energy, 1999Abstract Solar air heaters of many types have been developed in India and their performance studied in detail. The application of these air heaters are limited to a few demonstration projects for food dehydration, and space heating. Some of these case studies are described in this paper.

Energy, 1983
Abstract An air heater, in which the air first flows between metallic and cover plates and is then made to flow between two metallic plates in opposite direction, is discussed theoretically. The governing equations of the model are solved explicitly under suitable conditions.

Theory of baffled solar air heaters
Energy, 1992Abstract Considerable improvement in the collector efficiency of solar air heaters can be obtained if the fins in the collector have attached baffles to create air turbulence and an extended heat-transfer area. In this paper, energy balances in baffled solar air heaters have been developed and a theoretical equation for estimating the collector ...

Exergy analysis of an air solar heater
International Journal of Exergy, 2012This paper presents an exergetic analysis of a downward flat plate collector, an unglazed selective absorber collector and an artificial rough surface collector. The analysis is based on mass, energy and exergy balance equations. The results show that for the Reynolds number of Re = 4000, the daily exergy output rate varies inversely with the mass flow

Diurnal response of solar air heaters
Applied Energy, 1981Abstract A time-dependent heat transfer model has been developed to predict the diurnal performance of a conventional solar air heater which consists of a flat passage between two metallic plates through which the heating fluid (air) is made to pass. The effect of various parameters such as the heat capacities of the glass cover, the absorbing plate ...

Solar Air Heater for Preheating The Air of Broiler House
2018 International Conference on Sustainable Energy Engineering and Application (ICSEEA), 2018Theoretical studies have been conducted on the application of solar air heater for preheating the air of broiler house. The air heating system of broiler house was use a gas air heater and equipped with rocks bed as the thermal storage medium. The study was conducted for the broiler house with the capacity of 30,000 chickens, which is a house with a ...

High efficiency solar air heater
Solar Energy, 1997This article presents an analysis for a novel type of solar air heater. The main idea is to minimize heat losses from the front cover of the collector and to maximize heat extraction from the absorber. This can be done by forcing air to flow over the front glass cover (preheat the air) before passing through the absorber.
