WebFor example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%. A powerful storm will continue to affect the eastern third of the country with severe thunderstorms, strong winds and heavy snow. When you convert from a vented crawlspace with HVAC systems outside the heated and cooled envelope to a sealed crawlspace with HVAC systems and everything else in the crawlspace inside a favorable environment there is likely a net energy savings for sealing the crawlspace and a direct gain on drying the space out. air). For example, on a 40F day if the dew point is 36F the relative humidity would be 90%. Is dry or wet heat worse? Enter the air temperature as 95 F (35 C). Holloman AFB Radar, Forecasts As air conditioners lower the temperature of the air, they remove humidity.
