If you’re worried about your rising energy bill, chances are windows and walls that are poorly insulated might be the culprits. Heat losses from such parts of buildings and homes can jack up the total energy used, increasing your bills and wasting a tremendous amount of energy.
Generally, expensive infrared cameras are used to compare energy efficiencies of different parts of buildings. But, these provide only a temperature, rather than the energy used, thus sometimes providing an inaccurate view of the energy efficiency of a building and the effectiveness of the insulation. Also, the different reflectivities of surfaces may greatly affect their accuracy Hence; if you want to figure out how much you could be saving by switching over to better energy efficient insulating materials, there is no good way to do that.
Heat Flux occurs through all areas of a building envelope. FluxTeq's PHFS-09e heat flux sensors can measure this heat transfer directly. (Source: https://fet.uwe.ac.uk)
Applications of Heat Flux Sensors
That’s where heat flux sensors developed by FluxTeq can help. These sensors can be placed on walls and windows simply by using a double stick tape and can measure the heat dissipated through surfaces, or heat flux, rather than just measuring the temperature. The measured heat flux can then be compared to the total heat flux of the building and the energy costs.
The picture shows the FluxTeq heat flux sensor placed on a window. The readout is seen on an LCD device (Texas Instruments, sold separately, programmed by FluxTeq) and shows the heat flux as well as the inside window temperature obtained using an integrated thermocouple.
By measuring the heat loss or gain through materials using the heat flux sensor, one can quantitatively compare how good the insulating materials are. It is important to determine this as the performance of insulation materials changes depending on the use environment. Also, if a thermocouple is placed on the outside surface of the window, the outside surface temperature can be measured. Using this, the thermal resistance, or how good the material is in transferring heat, can also be measured.
These are only a few possible applications of these sensors and FluxTeq can work with you to customize the sensors based on your requirement and can supply them in large quantities. Contact FluxTeq for discussing your needs.
