質問 # 70
What happens to the surface of a wet material as moisture evaporates?
正解：D
解説：
As moisture evaporates from a wet material, the surface temperature of that material typically becomes cooler. This occurs because evaporation requires energy (heat) to change water from a liquid phase into a vapor phase. In restorative drying, that energy is drawn from the material and its immediate environment, producing a cooling effect at the evaporation interface commonly referred to as "evaporative cooling." The WRT body of knowledge explicitly states that as moisture evaporates from wet material, the surface becomes cooler because energy is released from the material during the phase change.
This cooling effect is not just theoretical; it is used in field practice to help locate moisture. TheWRT reference explains that thermal imaging cameras often "detect" wet areas primarily by observing cooler surface temperatures associated with evaporative cooling. Where evaporation is occurring, cooling typically occurs, and those cooler signatures can help identify areas that may be wet-subject to confirmation with moisture meters due to potential false readings.
From a drying-system perspective, evaporative cooling also helps explain why increasing air movement, controlling humidity, and managing temperature are interdependent. If evaporation is strong, the surface cools, which can reduce evaporation potential unless the system supplies adequate energy (heat) and maintains low vapor pressure in the surrounding air. Thus, the "cooler surface" outcome is an expected physical consequence of evaporation and a measurable indicator that the drying process is actively occurring at the material boundary.
質問 # 71
If the ambient temperature is below 50°F, what is the most effective type of dehumidifier to use when drying a structure?
正解：A
解説：
The IICRC WRT body of knowledge states thatdesiccant dehumidifiersare the most effective option when ambient temperatures fall below approximately50°F. Refrigerant-based dehumidifiers rely on condensation at cold coils and become inefficient or inoperative at lower temperatures due to coil icing and reduced moisture removal capacity.
Desiccant systems remove moisture throughadsorption, a chemical bonding process that is not dependent on air temperature. This allows desiccants to perform effectively in cold environments where refrigerant units fail.
The WRT manual highlights desiccants as the preferred solution for cold structures, unheated buildings, winter losses, and Class 4 drying scenarios. Gas bypass and LGR units extend the operating range of refrigerants but still have temperature limitations.
Selecting the correct dehumidifier type based on ambient conditions is a core competency under the WRT standard and ensures efficient, defensible drying.
質問 # 72
Why does drying affected materials behind vinyl wallpaper create a challenge?
正解：D
解説：
The IICRC WRT body of knowledge identifies vinyl wallpaper as avapor barrier or vapor retarder, which significantly restricts the movement of moisture vapor from wet materials into the surrounding air. This characteristic makes drying behind vinyl wallpaper particularly challenging because evaporation-the primary mechanism of restorative drying-is impeded.
In normal drying conditions, moisture migrates from wet materials toward lower vapor pressure air. However, vinyl wallpaper inhibits this vapor diffusion, trapping moisture within wall assemblies. As a result, even when ambient air conditions are favorable, moisture remains behind the covering, prolonging drying times and increasing the risk of secondary damage such as microbial growth or material deterioration.
The WRT manual explains that when vapor barriers are present, restorers often must employdisruptive drying methods, such as removing or perforating the wall covering, or using inter-air drying systems to introduce airflow directly into wall cavities. Without such intervention, surface drying may occur while concealed materials remain wet-creating a false impression of successful drying.
This concept reinforces the WRT principle that drying strategies must account formaterial permeability, not just moisture presence. Vinyl wallpaper is neither porous nor breathable and therefore prevents normal drying dynamics from functioning effectively. Recognizing vapor barriers is a key part of inspection and drying method selection under the IICRC standard of care.
質問 # 73
In order to increase the rate of evaporation, what should the surface temperature of the material be?
正解：D
解説：
The IICRC WRT body of knowledge explains that to increase therate of evaporation, the surface temperature of wet materials must beabove the dew point temperatureof the surrounding air. When a surface is warmer than the dew point, water molecules have sufficient energy to change from a liquid state to a vapor state and move into the air.
If a surface temperature falls at or below the dew point, condensation occurs instead of evaporation, adding moisture back onto the material. This condition directly opposes drying and can result in secondary damage.
The WRT curriculum therefore emphasizes continuous monitoring of both air dew point and material surface temperatures to ensure evaporation conditions are maintained.
Relative humidity is not a temperature, and vapor pressure equality does not drive evaporation. Only maintaining surface temperatures above dew point ensures positive evaporation potential.
This principle is fundamental to restorative drying and is repeatedly reinforced throughout WRT psychrometric training.
質問 # 74
In order to effectively dry subflooring installed below sheet vinyl flooring, what should a restorer typically do?
正解：B
解説：
The IICRC WRT body of knowledge explains thatsheet vinyl flooring acts as a vapor barrier, significantly restricting moisture vapor movement from the subfloor beneath it. Because evaporation is inhibited, subflooring beneath vinyl cannot be effectively dried while the covering remains intact.
As a result, the WRT manual states that the most effective and reliable method is toremove and discard the vinyl flooringto allow direct access for drying. This enables airflow, temperature control, and dehumidification to act directly on the wet subfloor.
Perforating vinyl is unreliable and may cause additional damage without ensuring adequate vapor release.
Placing an air mover at an edge does not overcome the vapor barrier effect. Simply adding equipment without removing the barrier does not resolve the drying limitation.
Removing vinyl aligns with the WRT principle that vapor barriers must be addressed to achieve effective drying and prevent hidden moisture from causing secondary damage.
