Abstract: An analytical expression for instantaneous thermal efficiency (n)of a greenhouse in terms of design and climate parameters has been derived by considering the energy balance equations for different component of the greenhouse.The present analysis can be used for testing the suitability of greenhouse of different size and shapes for given climate condition.Numerical computation for determination of instantaneous thermal efficiency(n)and greenhouse efficiency factor(F)have been carried out for a typical greenhouse.Parametric studies have also been carried out to predict the performance of the system.Expremental validation has also been reported for a climate condition of delhi.It is observed that:(i)there is a fair agreement between theoretical and expremental observations and(ii)the instantaneous thermal efficiency(n)increases with increase of relative humidity(y)due to less evaporation as expected.
