Optimize processes in a highly complex, full of variables and where the risk of redundancy of production processes is high. Here are the reasons for the birth almost ten years ago of the JDF, the Job Definition Format.

Towards the end of the 90 major multinational companies supplying the printing industry came together in a consortium called then CIP3. These included today the names of Adobe, Agfa, Heidelberg, Man to which have been added over the years also Fujitsu, Dalim, HP, KBA, Komori, Mitsubishi, and many more Océ.

The thermography measure the surface temperature of a building component, in function of the emissivity of the material, using a video-camera infrared. The cameras see the light of the electromagnetic spectrum that is perceived as heat, infrared.

The images or video camera record the temperature variations of the building, ranging from white for warm regions to black for cooler areas.

Heat pumps there are of many types; applications, then, are the most diverse, being able to be used not only for heating the environment, but also for the production of hot water, or in industrial dryers, and in general in all situations which require heat at a temperature not very high.

But we have chosen to deal with the heat pump for domestic heating. In this part I have tried to give an overview targeted to belong to this category, and indicate strengths and weaknesses, as well as highlight, for each of the characteristics to be evaluated.

PV: CELLS AND PANELS

Without going into technical explanations about the process dir realization of the panels and on the principles of operation of the cells (which would lie outside the scope of these post), but we can say that a photovoltaic cell (or the base unit which will then be assembled with other for constitute the panel) uses the photoelectric effect to generate electricity from energy contained in solar radiation.

At the ends of the single cell will be measured and then a potential difference (voltage) that depend on the characteristics of the cell and the incident solar radiation.

Let's see how to design a heating system, both as a sizing that from the economic point of view. Should add at once that there are two different "technical": the "well done" and the "-thumb". In the first part we see the design "well done", however, if the system is simple, there is nothing wrong to use the second one, because otherwise the costs of the design alone could become comparable with the entire system!

The most appropriate design that can be done is divided into the following phases:

Evaluation of the dispersion of the building / apartment This phase tends to simply establish, for each room, the power required to maintain the set temperature, when they occur outside the most severe climatic conditions.

These are the materials that are used in the construction industry. There are different types, sourced both natural and man-made, and over time have been created for new, more effective. Obviously, each material has specific properties that make it more or less suitable for different purposes for which it could be used in a building.

Historical Background

The first materials used by man to build the tents in which they lived were the skins of animals, were later used mud and clay raw, the straw huts, and different types of rock. There are many Aboriginal and nomads who, in different parts of the world still use these materials for their homes, in industrialized countries instead he's lost almost all uses.

Michael Grätzel, inventor of the dye-sensitized solar cells, those made with organic dyes, wins the Millennium Technology Price.

A sign of confidence in a technology that, thanks to very low prices and application flexibility, it promises a lot in a not too distant future.

"For his invention and development of organic solar cells, known as 'Grätzel cells', whose excellent price-performance ratio will allow them to have a huge potential to enter the future portfolio of energy technologies." It reads the dedication of the Millennium Technology Price, awarded last month to Michael Grätzel, Director of the Laboratory of Photonics of the Ecole Polytechnique Fédérale de Lausanne, along with 800 thousand euro to be invested in research.
