The lowest temperature which can be achieved through evaporative cooling at 100% relative humidity. It signifies the potential for evaporative cooling in air and is critical in cooling tower design.

The temperature at which air reaches saturation and moisture begins to condense, forming dew, fog, or clouds. It is a direct indicator of the moisture content in the air.

A ratio, expressed as a percentage, of the amount of moisture the air is currently holding compared to the maximum it can hold at a given temperature. Significant for human comfort and various industrial applications.

The mass of water vapor present in a unit volume of air, typically expressed in grams per cubic meter. It is significant because it provides a direct measure of the amount of moisture in the air.

The temperature of air measured by a thermometer freely exposed to the air but protected from radiation and moisture. It is significant as the most common measure of air temperature.

The rate at which heat must be added to a space to maintain a desired temperature. Essential for calculating the capacity of heating systems in buildings.

A graphical representation of the physical properties of moist air. It is a vital tool for engineers and meteorologists for determining air conditioning processes and analyzing climatic conditions.

The total heat content of air per unit mass, including both sensible and latent heat. It plays a key role in the design and analysis of heating, ventilating, and air-conditioning systems.

The rate at which outdoor air is introduced into a space. It is significant for maintaining indoor air quality and for diluting indoor pollutants.

The volume occupied by a unit mass of a substance, often measured in cubic feet per pound or cubic meters per kilogram for air. This property aids in the design of ventilation systems and understanding air properties.

The quantity of heat needed to raise the temperature of a unit mass of a substance by one degree. For air conditioning, it helps in calculating the energy needed to heat or cool air.

The rate at which heat is removed from a space to maintain a desired temperature. It is a determining factor for the size of air conditioning equipment required for a space.

The amount of heat energy required to convert a unit mass of a substance from liquid to vapor at constant temperature. It is critical for designing dehumidifiers and understanding moisture removal.

The process of adding moisture to the air, usually to meet a desired relative humidity level for comfort or industrial applications. It is important in preventing dry air conditions that can cause discomfort or damage materials.
