In central air handling units cooling and dehumidifying of the air usually takes place using chilled water cooling coils with one of the two kinds of circuits: temperature controlled or mass flow controlled chilled water supply circuits.<br><br> <strong>Technology</strong><br> The invention combines both types, the temperature controlled and mass flow controlled chilled water supply in one water circuit arrangement. Thus combining the advantages of the temperature controlled circuit with those of the mass flow controlled chilled water supply circuit, without the disadvantages immanent in the two circuit systems.<br><br> A simple but very effective valve arrangement, combined with a variable speed pump (see Figure) allows simultaneous control of the mass flow and the water supply temperature. The supply water temperature determines the slope of the change of condition and the mass flow controls the cooling power applied to the air. This allows cooling the air with or without dehumidification as well as dehumidifying the air with a minimum amount of cooling, resulting in substantial energy savings.<br><br>

Using ultrashort laser pulses, scientists in Max Planck Institute of Quantum Optics have demonstrated the emission of extreme ultraviolet radiation from thin dielectric films and have investigated the underlying mechanisms.
In 1961, only shortly after the invention of the first laser, scientists exposed silicon dioxide crystals (also known as quartz) to an intense ruby laser to...
The only professorship in Germany to date, one master's programme, one laboratory with worldwide unique equipment and the corresponding research results: The University of Würzburg is leading in the field of biofabrication.
Paul Dalton is presently the only professor of biofabrication in Germany. About a year ago, the Australian researcher relocated to the Würzburg department for...
Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
