EFFECT OF CO₂ SUPPLY STRATEGY ON SPECIFIC ENERGY CONSUMPTION

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.
