The use of solar energy for growing cucumbers in pots and the ground has been studied under controlled environments in a solar greenhouse. Forced and evaporative cooling were employed. An average of 7 cucumbers per pot (1342.4 g) was produced. Linear and multiple regression analyses were used to...

We have developed a procedure for assessing the economic viability of a solar water heater in a dynamic economic environment. The optimum life time for replacement of the system and the payback period are calculated for different interest rates and different increases in maintenance. It is...

We have evaluated the five typical shape of the greenhouse for energy conservation in winter months for a composite climate. An expression for the plant temperature has been used for steady state analysis. Numerical computation has been carried out for the climatic condition of Delhi, India. The...

We present an analysis of an active winter greenhouse in terms of design and climatic parameters. The analysis is based on energy-balance equations for each system component. The effect of energy storage by a brick wall at the north side has been incorporated in the analysis. The proposed design...
