Abstract

This is the third 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 model of an evaporative pad heating greenhouse has been developed. This model uses readily obtainable data regarding plant kinetics and climate conditions. The outputs include the time to harvest, crop yield, 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.
