Analysis of a glass solar air heater
Energy Conversion and Management, 1983Abstract A matrix solar collector fabricated from broken glass pieces is being supposed to be a thermally efficient and economically cheap system for heating air. In this communication, we develop an analysis to study the performance of such a system.

Efficiency of solar air heaters with baffles
Energy, 1991Abstract Considerable improvement in the collector efficiency of solar air heaters is obtained if the fins in the collector are provided with attached baffles to create air turbulence and an extended heat-transfer area. This procedure will increase the pressure drop for the air across the heater and thereby leads to some increase in the power ...

Energy Conversion and Management, 2012
Abstract Two low cost solar air heaters viz. single glazed and double glazed were designed, fabricated and tested. Thermocole, ultraviolet stabilised plastic sheet, etc. were used for fabrication to reduce the fabrication cost. These were tested simultaneously at no load and with load both in summer and winter seasons along with packed bed solar air ...

Compact Solar Air Heater: A Review
2019In this review work, a theoretical study of solar air heater is carried out by considering compact heat exchanger criteria into account. The present investigation comprises different performance parameters for a compact solar air heater. In this review work, Reynolds number is the only variable parameter which varies from 4000 to 18000. Stanton number (

Simulation study of solar air heater
Solar Energy, 2003A mathematical model for predicting thermal efficiency, heat gain, and outlet air temperature of a covered plate attic solar collector under steady conditions was developed. The model presented in this paper utilizes the basic principles and relationships of heat transfer to simulate the behavior of the solar air heaters under various conditions.

Evaluation of a matrix solar air heater
Energy Conversion and Management, 1990Abstract This paper presents the theoretical analysis along with the experimental validation of a matrix solar air heater, with air flowing downward and upward through the matrix. The heat balance equations governing the behaviour of the system are solved explicitly. The results obtained from the analytical expressions for outlet temperature compared

Solar Air Heaters and Their Applications
1977The solar air heater appears to be the most logical choice, as far as the ultimate application of heating air to maintain a comfortable environment is concerned. One disadvantage of solar air heaters is the need for handling larger volumes of air than liquids due to the low density of air as a working substance.

A thermodynamic review of solar air heaters
Renewable and Sustainable Energy Reviews, 2015Solar air heaters (SAHs) form the foremost component of solar energy utilization system. These air heaters absorb the irradiance and convert it into thermal energy at the absorbing surface and then transfer this energy to a fluid flowing through the collector.

Performance studies on solar air heaters
Solar Energy, 1967Abstract This paper reports an experimental study on the performance characteristics of four solar air heaters. Two were of a corrugated type and two were of a mesh type. All used ordinary black-painted surfaces. Instead of comparing the efficiencies at the same rate of discharge, the same amount of pumping power was employed so that the unequal ...

Evaluation of the performance of the solar air heater
Energy Conversion and Management, 1994In this paper, we analyse the performance of a suspended plate solar air heater working at low and moderate temperatures with a fluid flow on both sides of the absorber plate. A theoretical model for the system and subsequent numerical analysis of the system is presented in steady state.
