Air handling units: integrated solutions for energy savings

By Anonymous -


The AHU applications are characterized by a great range of plant solutions with different integration levels. Carel, leader on the regulation in HVAC/R world, thanks to the ten-year experience on designing and producing electronic controllers, humidifiers and accessories, offers the most complete solution range for this application.
The modular structure of the controllers, the different humidifiers available and the complete range of accessories let you set any kind of installation, which increasing integration leaves up to the complete supervision of the plant to reach the absolute reliability and the maximum energy saving.
The system approach joins with the flexibility of the solutions, both hardware, i.e. architecture and components, and software, starting from the standard up to the complete customization of the application software thanks to 1tool programming tool.

Flexibility: I/O chip technology means all the most common types of sensors can be read: the signal channel can also be configured to read digital inputs or pulse signals or can even be used as an additional analogue output to drive modulating device, which are commonly used on AHUs.

Connectivity: 5 serial connections to share data with several local or remote BMS, or FieldBus integration of smart actuators (inverters, dampers, valves, humidifiers,..).

Usability: USB. The two USB ports (host-device) can be used to connect pendrives for updating the software or downloading logs, or alternatively to connect directly to a PC for commissioning.

Memory: More space for more languages on the user interface, and to save the many significant variables for analyzing AHU operation.

Know How: Carel's experience in HVAC, especially regarding humidification and evaporative cooling, represent important added value for this controller, making it ideal for managing AHUs.

Standard application software for AHU control: The application software guarantees the maximum adaptability to each AHU, providing all the most common working modules for air handling units.
Moreover it is possible to choose the position of each input and output, allowing you to change the I/O on site during installation.
Its versatility matches with its configuration ease, thanks to the simple and intuitive user interface: the use of icons allows its comprehension to the less expert users, showing wizard and suggestions if necessary. The user interface is organized according to a menu divided in macro-areas (tree architecture) to which it is possible to access according to the level (the manufacturer parameters are password blocked): a careful display management let you scroll only the parameters required according to the enabled functions.

Energy savings: Carel solution combines the adiabatic humidification and the evaporative cooling , providing a global solution for the energy savings of air handling units.

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...
