To guarantee your customers are getting the performance they request, check for ARI Certification. ARI Certified products are tested for energy transfer effectiveness (sensible, latent, and total), cross leakage, and pressure drop. If a manufacturer states that their products are tested "in accordance with" ARI Standards that DOES NOT mean they are certified. To be certified, products must be tested by ARI and have annual check tests.

A psychometric chart is a design tool to graph a building's HVAC thermodynamic air conditions and processes. Properties displayed on a chart include dry-bulb temperatures, wet-bulb temperatures, dew point temperatures, relative humidity, humidity ratio, specific volume, and enthalpy. A link is provided to a downloadable software program that allows the user to electronically plot conditions on a psychrometric chart. This program version permits the user to enter state points and graph the air conditioning process, while also calculating additional air properties.
