Abstract

This is the fifth in a series of articles on the development of a methodology for assessing waste heat utilization technologies and optimizing the mix of technologies used on a site-specific basis. As part of this effort, a surface heated greenhouse model has been developed and is described. The model uses readily obtainable data regarding plant kinetics, climate conditions, and the inlet water temperature. The outputs include the time to harvest, crop yield, outlet water temperature, and mass flow rates of heated water in and out of the greenhouse required to maintain the desired temperature. This model has been used in simulations in order to assess the economic feasibility of this method of utilizing waste heat.
