A Techno-economic Model for Heating of a Greenhouse Site Using Waste Heat

摘要

Considering a greenhouse site, a waste-to-heat greenhouse heating techno-economic model is presented in this study. The contribution of the parameters affecting the heating costs in the total expenses has been put forward. The economic model can be used for different types of heat sources and allows making a comparison easily. According to the results, the main operating cost is the heating cost. According to the parametric study, the effect of the cover material on the heat losses is very little but the effects of the night temperature set points have an important effect on the heat losses.
