Investigation of the Temperature–Humidity State of a Tent-Covered Attic

The results of theoretical and experimental studies of the temperature–humidity state of a tent-covered attic are presented. The investigations were carried out in the attics of administrative buildings in Poltava. It was performed an analysis of the possibility of formation the ice area on the surface in the winter–spring period, which prevents the flow of meltwater from the roof. The accumulation of meltwater on the roof leads to leakage of water through the leaky joints of metal sheets on the attic floor. This phenomenon occurs in the case of simultaneous presence on the cover of the positive and negative temperatures. The range of external temperatures at which this phenomenon occurs is revealed. The attic air temperatures at which the formation of ice on the surface is minimized are found. The analysis of the possibility of condensation on the inner surface of the roof at the current temperature–humidity state of air in the attic is performed. The air temperature in the attic at which moisture condensation does not occur is revealed.
