The Microclimate of a Ten-Man Arctic Tent. Part I: A preliminary Investigation.
Abstract
Some parameters of the microclimate of a ten-man tent in winter were measured. A living zone of the tent was outlined, and the average living zone temperature defined. Living zone temperatures, and temperature distributions produced by standard heating systems under various weather conditions were determined. A minimum safe living zone temperature was derived as well as a minimum temperature for comfort. Ventilation of a well weather-proofed tent was found to be low, and controlled by the restriction on air inflow at the base, rather than on air outflow at the peak. This observation has particular importance in tents with floors. Experiments were performed to determine the effect of the liner on interior temperature levels, the effect of a lowered ceiling, and of adding a stack to a heater and venting the exhaust products. Carbon dioxide and monoxide levels were measured, as was the dew point of the air at several levels in the tent.
