Example Application
The following example demonstrates how to apply the recommended temperatures using the data:
With an outside dry-bulb temperature of 30°C (approximately 86°F), the recommended inside dry-bulb temperature is approximately 26°C (79°F), and the recommended inside wet-bulb temperature is approximately 17°C (63°F). According to the Mollier diagram, this corresponds to a relative humidity of about 40% and a humidity ratio of 0.0085 kg H₂O/kg dry air.
