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

Description

Calculates the enthalpy of a given moist air state. Eq. 32 - ASHRAE Fundamentals Handbook 2002, Psychrometrics.

Usage

enthalpy(temp.db, hum.ratio)

Arguments

temp.db	Vector of dry bulb temperatures [degC].
hum.ratio	Vector of humidity ratios [kg/kg].

Value

Returns a vector of enthalpies [kJ/kg].

Examples

enthalpy(25, 0.010)

# Calculating cooling demand
density <- 1.2 # density of air (kg/m3)
(enthalpy(35, 0.020) - enthalpy(15, 0.010)) * density
