Comments on: Nice Dutch project using ‘waste’ heat and CO2 to increase greenhouse yields! http://greenmonk.net/nice-dutch-project-using-waste-heat-and-co2-to-increase-greenhouse-yields/ Green from the roots up, Sustainable from the top down Mon, 15 Mar 2010 18:34:20 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Clogmeister http://greenmonk.net/nice-dutch-project-using-waste-heat-and-co2-to-increase-greenhouse-yields/comment-page-1/#comment-7611 Clogmeister Sat, 24 Oct 2009 18:17:48 +0000 http://greenmonk.net/?p=1591#comment-7611 The residual heat has to be cooled down by the greenhouses to an exact temperature (I thought 43C) which is laid down in a contract with Yara. If cooling down to that exact temperature is impossible then the whole heat exchange system gets decoupled and the heat will destroyed (i.e. not used for heating). Yara cannot afford a complete system shutdown because of high temperature return water. Greenhouse automation company Priva will provide the special software for most of the growers (disclaimer: I worked for Priva as a software engineer).
