Dynamic simulation of the performance of an inflatable greenhouse in the southern part of Alberta. I. Analysis and average winter conditions

Abstract

Numerical simulation of the performance of an inflatable greenhouse for average January winter weather conditions in southern Alberta is carried out. The greenhouse is modeled by several ‘layers” and equations of energy and vapor transfer are derived. Numerical solutions are obtained for a range of values of various parameters. It is shown that with sufficient heating and ventilation, it is possible to maintain a suitable temperature distribution inside the greenhouse and avoid ice formation on the cover. The effect of random wind speed variation on the operation of the greenhouse is also investigated.
