INSTANTANEOUS THERMAL LOSS EFFICIENCY FACTOR FOR SUMMER GREENHOUSE

In this technical note, an attempt has been made to develop an analytical expression for an instantaneous thermal loss efficiency factor for a summer greenhouse. The analysis is based on energy balance equations for each component of the greenhouse in a steady state condition. Effect of design and climatic parameters have also been taken into account. An ideal condition has been achieved analytically, for a best summer greenhouse. The nature of characteristic curve obtained by the present model has been compared with the experimental results obtained by others.
