Abstract

A method is presented which will enable determining the ventilation rate in commercial greenhouses.
The method is based on the use of carbondioxide (CO2) as tracer gas.
CO2 is choosen for the reason that CO2 supply and measuring equipment is present on many nurseries (in the Netherlands).

A series of measurements is performed in glasshouses without a crop at changing windvelocity (2.5 – 6 m/s) and various window apertures (0 to 15 %). From the data a relation is established describing the ventilation rate (m³ air exchange per m³ greenhouse volume per hour) as a function of wind velocity and window aperture.

The problem of interference of the tracer gas concentration by CO2 produced by organisms in the soil, is studied with a calculation program.
