Hukseflux Introduces the Hot Cube Human Thermal Comfort Measuring System – A New, Innovative Tool for Automotive Testing and Research and Education

Delft, Netherlands, January 14, 2019 –(PR.com)– TCOMSYS01 is a measuring system to help understand and quantify �causes and effect” leading to human thermal comfort. The included TCOM01 body is temperature stabilised at 33 °C, so that it offers a relatively direct measurement of the human experience. In essence, TCOM01 is a miniature thermal mannequin, measuring according to the innovative Hot Cube method. The heater power required to keep the TCOM01 at a constant temperature is the main measurand. Incorporating 5 heat flux sensors with a black absorber, it also offers a detailed picture of the heat gain and loss from different directions, and a good indication of convective and radiative asymmetry. Other measurements are sensor body temperature, air temperature and relative humidity. In its standard configuration, the system consists of an MCU (Measurement and Control Unit) and a TCOM01 sensor on a tripod. The MCU offers direct connection to any local area network and “Ethernet over USB.” TCOM01 is also available as a sensor only.

Already in 1929 the Eupatheoscope (from Greek “wellbeing–emotion–examination”) was designed by A.F. Dufton to quantify the condition in a room from the point of view of comfort. It consists of a blackened cylinder which is controlled to maintain a temperature of 23 °C. The power used is interpreted in terms of equivalent temperatures. In the 1990’s, the company Bruel & Kjear carried a thermal comfort meter (model 1212), based on the same principle, and in addition processing Fangers equation. Both models involved only an integrated power measurement. The new Hot Cube method improves on this by incorporating omnidirectional heat flux measurements.

TCOMSYS01 is small enough to work in confined environments such as the passenger compartment of a car. Besides applications in the automotive industry, there are more usage examples of the Hot Cube system:
· surveys of human thermal comfort
· studies of the effect of radiating sources
· workplace investigations
· educational purposes, illustrating heat transfer
· bio-meteorology
· microclimate studies
· wind-chill analysis
· analysis of fabric insulation
