【Manually drive back to the southern sky】Feel comfortable when the relative humidity is around 60%. Relative humidity, which can be seen as the percentage of water vapor pressure in the air and saturated water vapor pressure at the same temperature. Look up the table to know the saturated water vapor pressure at a certain temperature, the dew point temperature is the temperature when the water vapor content is unchanged to reach saturation, that is, the dew point temperature can know the current water vapor pressure E. Assume that the air pressure and density in the room are constant or the change is minimal. Is it not as long as the temperature is adjusted to the temperature of saturated water vapor pressure of E÷ 60%, you can get a rare dryness in the southern days? For example, guangzhou at 9 o'clock in the morning temperature of 15.5 °C, dew point temperature of 13.7 °C, and to reach 60% of the relative humidity of the temperature needs to reach 22 °C (today at noon to try, the warm fan can be turned on to 22 °C can not be dry). Do you have any friends with HVAC engineers to analyze the feasibility of analysis?
Of course, it can also be more scientific and efficient, @ Deye dehumidifier to maintain a constant humidity of 55 ~ 65%, save back to the south sky and dry underwear. #广东人最怕的回南天要来了 #
