Thermal Comfort Measurement Solution

State of the art thermal comfort measurements according to international
standards
The ComfortSense system is designed for thermal comfort investigations where high quality
and accurate measurements are required. ComfortSense is designed to charaterize thethermal environment inside enclousures such as office buildings, theaters, automobiles,trains, and airplanes. ComfortSense is essential for the development of heating and air
conditioning systems requiring multi-point measurements of air velocity, temperature,humidity, and operative temperature. ComfortSense includes draught measurements withomnidirectional probes as well as high-velocity probes for ventilation ducts or other testfacilities.

Key benefits•

Up to 96 environment probes•

Measures draught, temperature, humidity, air velocity, and operative temperature
simultaneously.

•In accordance with EN 13182, ISO 7726, ISO 7730, ASHRAE standards 55 and 113•

User friendly software with graphical presentation of the results as well as tabular output•

Quantification of Predicted Mean Vote (PMV) and Predicted Percentage Dissatisfied (PPD)•Omnidirectional Draught Probes with fast +2 Hz response•

Calibrated Draught, High-Velocity Probes, and Humidity Probes•

USB interface•

Automatic Report generation•

Optional integration with LabVIEW software

Thermal comfort parameters
The ComfortSense system measures air velocity, temperature, operative temperatureand humidity with up to 16 probes per frame. Six frames can be connected so thatup to 96 probes can be monitored simultaneously. Statistical parameters suchas Predicted Mean Vote (PMV) and Predicted Percentage Dissatisfied (PPD) aremeasured by ASHRAE 55 and ISO 7730 standards.
Draught measurements require omnidirectional probes with a frequency response ofat least 2 Hz, which is fulfilled by the Draught Probes. They measure temperature inaddition to air velocity. Variants for mounting on a tripod or integration into thermal
manikins are available.Measurements near diffusers, grilles and supply nozzles
require a higher velocity range.
The High Velocity Probe measures up to 30 m/s as well as temperature in the range-20°C to +80°C.
The Operative Temperature Probe’s elliptical shape makes it possible to simulatelying, sitting or standing persons by inclining the probe to horizontal, 45 degrees orvertical position.

ComfortSense software
The software allows for easy setup of a measurement sequence and a measurement
grid with a selection of probes from a user-defined library. The software delivers
statistical results as tables, graphical plots or in Excel-compatible files, based on userdefined measurement cycles.
The software provides advanced graphics such as 3D contour plots which gives theresearhers a comprehensive overview of the measured data. This feature enables
the identification of problematic zones in the environment under investigation.
The operator can zoom, rotate and arrange all 3 planes individually for better
determination of the regions of interest.
The ComfortSense software can show the Predicted Percentage of Dissatisfied(PPD) based on the measured Draught, Operative Temperature, and Humidity as afunction of the Predicted Mean Vote (PMV). The calculation also takes the specified
metabolic rate (MET) and the clothing insulation (CLO) into account. The PPD andPMV calculations are described in the ASHRAE 55 and ISO 7730 standards

Options
Option: Transport Case for cables
Robust metal case with space for 4 20m cables.
Option: Battery Unit
A battery unit for your ComfortSense system can come handy in manyapplications, where you will need the extra mobility, where the power is
not accessible or in hazardous areas.
Option: Extra Probe Holder
For mounting of an additional probe on the Mounting Tripod
Option: Protective Cages for 54T34 Draught Probe
The 54T34 Draught probe - manikin version - is delivered with a compact
protective cage. This cage is available separately - type no. 54T41.
A larger version is also available - type no. 54T216
Option: Input Module for two Custom Probes
Custom probes can now be added to the Probe Library using a custom
calibration file in XML allowing integration of any OEM probe into thesystem, including advanced linearization and calculation between probe
channels. One input module type 54N94 can connect two custom probes.
