Psychrometry & Water Damage
Welcome to Psychrometry 101 for Water Damage Restoration brought to you by Aladdin's Restorative Drying. Below are the definitions for psychrometry as found in the dictionary mentioned.
psy·chrom·e·try (psy*chrom"e"try), n. Hygrometry. The calculation of relative humidity and water-vapor pressures from temperature and barometric pressure. Also called hygrometry.

However for Water Damage Restoration we will be using a slightly different definition:
Psychrometry: the study of the relationship between air, humidity, temperature, air movement, time and their affect on various materials and comfort levels. These factors determine the ability of the air to dry a structure and contents.
Using a thermal-hygrometer, the temperature and relative humidity of the air can be determined. With these readings we can determine the specific humidity or the grains of moisture per pound of air (gpp), using a psychrometric chart. This will tell us how much actual water is being held in the air, both inside a building and outside a building.
