PPD with Vertical Air Temperature Gradient

Description

Function to calculate vertical air temperature gradient using the predicted percentage of dissatisfied.

Usage

calcVTG(ta, tr, vel, rh, clo, met, v_tmp_grad)

Arguments

ta	a numeric value presenting air temperature in [degree C]
tr	a numeric value presenting mean radiant temperature in [degree C]
vel	a numeric value presenting air velocity in [m/s]
rh	a numeric value presenting relative humidity [%]
clo	a numeric value presenting clothing insulation level in [clo]
met	a numeric value presenting metabolic rate in [met]
v_tmp_grad	vertical temperature gradient between the feet and the head [degree C/m]

Details

Calculates the percentage of thermally dissatisfied persons with a vertical temperature gradient between feet and head. Applicable only for velocity(vel) < 0.2 m/s

Value

Predicted Percentage of Dissatisfied with vertical temperature gradient in [%]

Acceptability in [boolean]
