In chrras/climateeng: Tools to Calculate Climatic Comfort Related Parameters

Description

Calculates the dew-point temperature based on humidity ratios. Eq. 37 & 38 - ASHRAE Fundamentals Handbook 2002, Psychrometrics.

Usage

dewpoint(hum.ratio, alt = 0)

Arguments

hum.ratio	Vector of humidity ratios [kg/kg].
alt	Vector of altitudes [m]. Defaults to 0 m (sea level).

Value

Returns a vector of dew-point temperatures [degC].

Examples

dewpoint(hum.ratio = 0.010)

hum.ratio = seq(0, 0.050, by = 0.001)
plot(dewpoint(hum.ratio = hum.ratio), hum.ratio,
     xlab = "Dew-point [degC]",
     ylab = "Humidity ratio [kg/kg]")
