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>

KAIST researchers published an article on the development of a novel technique to precisely track the 3-D positions of optically-trapped particles having complicated geometry in high speed in the April 2015 issue of Optica.
Daejeon, Republic of Korea, April 23, 2015--Optical tweezers have been used as an invaluable tool for exerting micro-scale force on microscopic particles and...

Ever since computers have been small enough to be fixtures on desks and laps, their central processing has functioned something like an atomic Etch A Sketch, with electromagnetic fields pushing data bits into place to encode data.
Unfortunately, the same drawbacks and perils of the mechanical sketch board have been just as pervasive in computing: making a change often requires starting...
How is lightning initiated in thunderclouds? This is difficult to answer - how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, that cosmic rays provide suitable probes to measure electric fields within thunderclouds. This surprising finding is published in Physical Review Letters on April 24th. The measurements were performed with the LOFAR radio telescope located in the Netherlands.

Max Planck researcher Buhalqem Mamtimin determines how much nitrogen oxide is released into the atmosphere from agriculturally used oases.
In order to make statements about current and future air pollution, scientists use models which simulate the Earth’s atmosphere. A lot of information such as...
