Inputs |
||||
|
Dew Point Temperature |
Float |
Yes |
Indicates the dew point temperature of air, which is the temperature at which moisture condenses out of the air. If the Setup property is DP, this input represents the air dew point temperature that is used to calculate Enthalpy. If the Setup property is RH, this input is ignored. |
14 °C, 57 °F |
|
Dry Bulb Temperature |
Float |
Yes |
Indicates the temperature of air as measured with a simple thermometer. |
25 °C, 77 °F |
|
Elevation |
Float |
No |
Indicates the distance above or below sea level. Below sea level is represented with a negative value. |
0 ft, 0 m |
|
Relative Humidity |
Float |
Yes |
Indicates the relative humidity of air. If the Setup property is RH, this input represents the air relative humidity that is used to calculate Enthalpy. If the Setup property is DP, this input is ignored. |
