We have developed the theory of a matrix air heater with a rear plate, investigated the role of individual components, and studied the performance differences for air flowing downwards and air flowing upwards through the matrix. The system is compared with an air heater of conventional design...

The performance prediction of Solar Integrated Collector-Storage system(ICS) is determined in terms of three generalised non-dimensional grouped parameters using transient one-dimensional analysis. These non-dimensional parameters are primarily a combination of physical characteristics...

We have investigated the performance of a solar water heater with collector and baffle plate for six continuous days during the summer and winter seasons. The following cases were studied: 1.(i) no flow,2.(ii) constant water flow rates,3.(iii) intermittent flow to meet requirements of hot water,...

The performance of a built-in storage water heater can be improved by using a baffle plate in the absorber tank. We have studied the following different design conditions: 1.(i) a water heater with baffle plate and with night insulation cover,2.(ii) with baffle plate and without night insulation...

We present a theoretical analysis of three different configurations of double exposure solar air heaters. The heat-balance equations are written in each case and are solved explicitly. The periodic responses have been studied for different combinations of parameters. Measured values of solar...

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. The measured values of the...

The results of a comparative study of the steady-state approach and the periodic analysis as applied to the air heater are presented. For the periodic analysis, the meteorological data are represented by a Fourier series. The periodic analysis is carried out by taking half-hourly and hourly...
