Recommended indoor comfort temperatures vs. outdoor temperatures.
Recommended indoor comfort temperature versus outdoor dry-bulb temperatures are indicated below.
Indoor Comfort Temperatures vs. Outdoor Temperatures
Outside Dry-Bulb Temperature (oF)
Inside Temperature (oF)
Example - Recommended Indoor Temperature
With an outside dry bulb temperature of 30 oC, the diagram above indicates the the recommended inside dry bulb temperature should be approximately 26 oC and the recommended inside wet bulb temperature should be approximately 17 oC.
From the Mollier diagram this corresponds to relative humidity approximately 40% with humidity ratio - x - 0.0085 kgh2o/kgdry_air.
