The PCM cube maintains a temperature of 21 degrees Celsius until it is completly melted.

Online — When the summer sun burns in the sky, phase change materials (PCM) integrated in building envelopes absorb the heat – it remains cool inside.

When it is getting colder outside, the materials give off heat. Several grams of these storage media can protect against overheating and undercooling for a long time.

For the first time, researchers have combined insulating characteristics of foams with PCM thermal masses via established procedures of shaping processes.

Due to this combination of materials the heat transfer through walls is reduced for hours.

New Pyrometer for High-Temperature Uses & Metals

Calex’s New FibreMini

FibreMini fibre-optic pyromete

FibreMini fibre-optic pyromete

Leighton Buzzard, UK – The new FibreMini is a fibre-optic pyrometer from Calex Electronics with advanced features that allow accurate temperature readings on metal surfaces in harsh applications.

Measuring the surface temperature of metals is challenging.

Reflective surfaces, high ambient temperatures and harsh environments make it difficult to achieve accurate measurements with infrared temperature sensors.

The following features, provided as standard on all FibreMini models, make non-contact temperature measurement possible in these difficult conditions: Continue reading

Controlling Temperatures in Additive Manufacturing Machines

Thermwood Produces Solid, Void-free Parts

Easily Adjust Print Speed and Temperature

Adjust Print Speed and Temperature

Dale, Indiana, USA  —  Thermwood has added thermographic imaging as a standard feature to their large scale additive manufacturing machines (that they call LSAM L-Sam”).

This addition makes it easier to adjust and control the printing process, resulting in the best possible printed structures.

Know and Control the Temperature

In order to print high quality, void free large scale 3D printed structures, the previous layer must be cool enough to support the new layer without distortion, but must also be warm enough to fuse completely with the new layer as it is applied.

To accomplish this, we must first know and be able to control the temperature of the surface throughout the printing process. Continue reading

Online  —  Phase change materials (PCMs) are substances with a high latent heat (typically of fusion) which may be used to store a large degree of heat energy by melting and crystallizing at a certain temperature.

PCMs can be organic, inorganic, eutectics, and hydroscopics (where the phase change is not a change of fusion but rather of absorption and desorption of water vapor). Continue reading

The innovative cooling element reduces perceived temperature in just three minutes. Besides ambient climate control and lighting, the modular system also improves acoustics.

Online  —  Poorly maintained air conditioning systems cause mold or other bacteria to spread; they often also generate drafts and are costly to operate.

An alternative technology that uses ceiling panels covered in special heat-conducting film operates well below the dew point temperature.

Designed by Fraunhofer researchers, the system offers hygienic cooling even in tropical climates, and uses up to 70 percent less energy.

The multifunctional system will be launched at the BAU trade fair from January 16-21, 2017 as part of the Fraunhofer Building Innovation Alliance’s special show, “Fraunhofer CityLaboratory – creating living spaces” (Hall C2, Booth 538). Continue reading

Infrared hyperspectral imaging of ship plumes

Characterizing the spectral features enables the standoff detection of distant ships

22 November 2016, SPIE Newsroom. DOI: 10.1117/2.1201610.006718

Infrared hyperspectral imaging of ship plumesSPIE Newsroom — “Detecting naval vessels based on their IR characteristics is a key task for many defense organizations.

“The emissions (i.e., the shape and thermal energy) of such vessels produce an overall IR signature that can be analyzed to detect and, subsequently, to track them.

“For this reason, numerous models have been developed over the years to predict the IR signature of ships.1

“The hot exhaust gases that are produced by a ship’s engine represent one of the main contributions to its signature. Many modern military vessels are therefore equipped with IR-signature suppression systems (i.e., where steam is injected into the exhaust gases to reduce their self-emission).2 Continue reading
