Psychrometry Study of the relationship between air, humidity, and temperature and their effects on materials and comfort levels Evaporation Process of changing a liquid to a vapor Dehumidification Reducing moisture content in the air Dry Bulb Temperature Temperature degree registered by a thermometer Dew Point The point at which humidity in the air reaches saturation or 100 Percent RH Saturation Point Point at which air or materials can absorb no more moisture, drying stops, and air temperature reached dew point Condensation Conversion of water from vapor state back to liquid state Relative Humidity (RH) The amount of moisture in a given volume of air, expressed as a percentage, at a given temperature Infiltration Migration of air into an area from an outside area due to high VP differential Balanced Drying Ideal drying situation in which the rate of evaporation is equal to or slightly less than the rate of dehumidification or ventilation GPP Unit used to measure humidity ratio 7000 Grains of water vapor Equals 1 pound of water 14 cubic feet of dry air Equals 1 pound Humidity Ratio The weight of suspended moisture in air expressed in GPP Hygroscopic Material that readily absorbs and retains moisture or water vapor from air in an attempt to reach equilibrium Moisture Content (MC) Weight or percentage of moisture in materials, as compared to the weight of oven dried , like material Permeance A measure of water flow through materials of specific thickness
