Automobile Cabin Comfort Testing
Airflow Analysis Instruments for Automotive HVAC Systems
Demands for increased comfort, concerns about interior air quality, and initiatives to reduce environmental impacts are affecting automotive HVAC system developments. New air modes, air purification, and eco-friendly automotive refrigerants are just some of the items under discussion. To quantify the performance of airflow systems in vehicles, from both the perspective of personal comfort and deployment efficiency of heated and cooled air, a grid array of multiple airflow sensors is required.
The °C Grid with datalogging software is ideal for automotive cabin comfort testing, measuring and recording air velocity and temperature at multiple points in real time. Using the °C Grid, clients are able to design acceptability criteria for air velocity and temperature, while changing blower speeds, vent angles, or open vent configurations, in order to create performance-based test and measurement plans. These tests can be saved and reused to baseline the performance of new or changed system designs and determine effects upon airflow and heat energy profiles. Compared to single measurement approaches, multipoint measurement with °C Grid is more repeatable and saves considerable development time.
°C Grid sensor layout, sensor quantity, and frame are built to client specifications. The profile can match a seat, dashboard, or span the width of a cabin.
Use the °C Grid airflow measurement and mapping solution to quantify your new automotive HVAC technologies and occupant comfort in vehicle cabins.

Airflow Measurement Instruments
Grid Sensor Array
The °C Grid is a comprehensive, multi-scalar solution versatile enough for any application where airflow and thermal conditions must be measured, mapped or managed.
Sensor Pole Array
Fully-configurable °C SPAR Sensor Pole Array system for linear air velocity, humidity & temperature measurement. System is custom built to meet user-defined specifications including pole dimensions, calibration ranges, and sensor quantities.
Data Acquisition
When testing conditions require numerous, simultaneous measurement locations, the single-point measurement approach is expensive, time-consuming and often yields inaccurate results.
