Comfort Index Measurement
Operative range
It is possible with this measuring setup to measure all the physical
parameters needed for assessing and evaluating thermal
comfort simultaneously on three levels. It reliably evaluates the
performance of heating and ventilating systems. The data acquired
from the series of measuring operations for operative temperature
(globe temperature), room temperature, and room air flow
and humidity, and the necessary input parameters (e.g. clothing
factor, activity level, mechanical output) is used together to calculate
the PMV (predicted mean vote) and PPD (predicted percent
dissatisfied) values (as per DIN ISO 7730) and the degree of
turbulence ( as per DIN EN 13779, formerly DIN 1946 Part 2);
these values are calculated either online or offline using the AMR
WinControl software in conjunction with the add-on module for
comfort index measurement.
The software
The averaging number is preset at 200 measuring points but this
is variable and can be modified. The PMV and PPD values and
the degree of turbulence can be displayed and documented in y/t
or x/y diagrams either each one separately or together with other
measurable variables. A software wizard is available to guide the
user step-by-step through the various settings. If measuring is
started online, the first value is indicated after completion of the
first 200 measuring operations (as per DIN ISO 7730). These
values continue to be calculated, updated, and displayed, and -
optionally - also saved and / or exported. (see Chapter 05)
