Energy saving solutions for data centers

Data center air-conditioning


Data center air-conditioning is essential for the correct operation of Information Technology equipment: processing and storage devices produce considerable heat that needs to be removed in order to maintain optimum operating conditions.

Worldwide data center power consumption is estimated to be 30GW, accounting for around 1.5% of the earth's total electricity usage: as a result of this astonishing level of energy consumption, energy saving solutions are increasingly adopted.
Currently the most widely implemented technological solution involves the use of Computer Room Air Conditioners (CRAC) or Close Controls Units (CCU), which cool and where necessary humidify the air in the data center.
Continuous technological development in the sector and a constant focus on energy saving are reflected in the evolution of the air-conditioning solutions adopted: from controlling air distribution to installing air-conditioners, near the heat sources, as well as using high efficiency equipment.
Moreover, air handling units can be used to deliver outside air in free cooling mode, and where possible lowering temperatures even further using adiabatic humidifiers (evaporative cooling).

CAREL and the dreaded 'NO LINK' Screen! Picture the scene, you've just downloaded a fresh new piece of software onto a controller but rather than the a new interface, you're met with a big fat 'NO LINK' message on the display. Or maybe you've just ran a factory reset to default settings and have come up against the same issue?  These are all possible causes for the common problem encountered by many of our customers, deemed the 'NO LINK' screen! (capitals for emphasis) As well as the two already mentioned, other common causes of the issue are a result of: A faulty connection between the Controller and the Display A faulty Controller  In any case, this issue is relatively simple to fix and our Managing Director, Stefano - having been in the Industry for 15+ years - has put together a video guide on how to do so. Watch the video below to see how to overcome the dreaded 'NO LINK' Screen!   www.i-acs.co.uk

Cold Rooms for food storage

Food storage uses various procedures that vary based on duration: Refrigeration, if the food must be stored for a short period of time (0…7 ° C). Freezing, deep freezing and lyophilisation (freeze drying) if it must be stored for long periods. When deep freezing the product it must reach a temperature of -18 ° C in less than 4 hours while for regular freezing the product can take more than 4 hours to reach -18 ° C. During lyophilisation the product is dried following a forced evaporation of the water component of the product. In the food industry, refrigeration is one of the most delicate and complex applications because food requires treatment at different temperatures depending upon the processing phase. Refrigeration slows the growth of bacteria on food. The technique is based on the extremely quick and intense action performed by the cold temperature that allows the organoleptic qualities of the food to be kept intact, prolonging storage time. Systems...
