To calculate the Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD) it is
necessary that are connected the following probes:
TP3276.2 or TP3275 globe thermometer probe.
HP3217.2 or HP3217R combined probe for the measurement of relative humidity and
the air temperature.
AP3203.2 or AP3203 probe with warm wire for the measurement of the air speed.
To calculate the Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD)
consider the regulations:
ISO 7726
ISO 7730:2005
2.1.3 Medium radiant temperature tr
The medium radiant temperature is defined as a temperature involving a fictitious thermal uniform
environment that would exchange with the beings the same thermal radiant power exchanged with
the real environment.
To check the medium radiant temperature we must detect: the globe thermometer temperature,
air temperature and air speed measured close to the globe thermometer.
The formula for calculating the medium radiant temperature is the following one:
In case of natural convection:
