| Abstract:
This paper studies the effect of CO2-dosing with exhaust gases on the efficiency of glasshouse tomato production. The paper shows that it can be recommended to ensure a continuing CO2 supply during the warm period. The discussion focuses on exhaust gases as a CO2 source, but the results also elucidate the effects of pure CO2. The efficiency is rated with respect to the ratio between primary energy consumption and biomass production. The computations are made with a greenhouse climate simulation model that includes the description of the heating system performance. The results hold for Dutch circumstances with respect to building characteristics, outside weather conditions and horticultural practice. | |
