Method for regulating the heat and CO2 concentration of the air in an enclosed space
US-7921596-B2Abstract
The invention provides a method for regulating the heat and the CO 2 concentration of the air in an enclosed space within which plants and/or crops are grown, in which method an oxygen-containing gas and a hydrocarbon-containing gas are alternately passed over a bed of particles that are capable of binding oxygen, wherein the oxygen-containing gas is passed over the bed of particles under conditions whereby the particles are oxidised and heat is released, after which at least part of the heat is provided to the enclosed space, and wherein the hydrocarbon-containing gas is passed over a bed of the oxidised particles so obtained under conditions whereby the oxidised particles are chemically reduced and water and CO 2 are formed, after which at least part of the CO 2 so obtained is provided to the enclosed space.
