Abstract
Analyses of the insulation requirements and ventilation rates for small, insulated tents were made and compared with both laboratory and field observations on two proto-type tents used during a winter trial. Predicted values of thermal resistance were in good agreement with measured values, although it was found that construction techniques could significantly alter the value of thermal insulation for the tent. Two analyses of the ventilation rate were made, one based on the conservation of thermal energy and the second based on a bouyancy driven pipe flow analysis. Predicted ventilation rates agreed with measured values to within a factor of two under calm conditions. An estimate of the minimum acceptable ventilation rate was made based on a stoichiometric combustion analysis of a generalized hydrocarbon fuel. TRUNCATED
