Control of speed and power in heat exchangers

By Anonymous -


Heat exchangers in general, whether for air/air applications or air/water applications (i.e., condensers), have a considerable weight in terms of efficiency and energy yield.
Even this element, which is essential for the correct design of the chiller cycle, must be properly managed and therefore requires electronic regulation.
The advent of electronically controlled brushless motors allows the refinement of the adjustments and noise reduction.
Carel offers a series of programmable controllers (pCO) that allow serial piloting of these loads, thus reducing the space, wiring installation complexity in general, allowing the management of a large amount of information in real time and rapid intervention in the event of anomalies or failures.
This is not the only option to satisfy the market: Carel completes the offer with the gamma inverter and is thus able to meet all of the customer’s needs. Built-in at either the panel level or for the entire solution, it is therefore total, a unique, high value package that allows standardization, cost reduction and new items to complete our customer’s catalogues.
They will then be able to furnish their excellent products with the new, highly technological offer.
There are different types of exchangers and CAREL is able to offer dedicated solutions for each application and need based on the available space, loads, types of motors used and, therefore, the regulation required.
CAREL is certified by the major international players in the ventilation industry.
The pCO controller, the heart of the regulation system, has software modules for managing the brushless fans, capable of taking advantage of the performance offered by the fan manufacturers.
Modbus serial communication allows easy and complete interfacing with the actuators in action, simplifies their wiring and reduces the space used.
The control panel is smaller thanks to the small number of electromechanical components since the electromagnetic switches are no longer necessary for power control.

CAREL and the dreaded 'NO LINK' Screen!

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

For those who think that the new generation of innovative, automated HVAC control systems are a far-off thought, think again!  The new c.pCO Range by CAREL marks the arrival of their most intelligent range of controllers yet. Despite their compact design, the c.pCO Controllers are packed with new and exciting technologies offering a highly integrated solution to any kind of BMS System.  The versatile nature of the new standard controller (2 Ethernet, USB & RS485 Inputs Built In) opens doors to a wide range of communication protocols such as Modbus, BACNet,  HTTP, FTP  and loads more. The video below offers a detailed look into the new features and benefits of the c.pCO range. Worried about having to do a lot of work to replace older controllers? As if this wasn't enough, all c.pCO Controllers offer pin-to-pin compatibility with pCO5+, pCO5 and pCO3 controllers.  Get in touch now for more information! Peter Campbell Marketing

1tool is the development system for the Carel programmable control platform, consisting of six different environments in which the designer manages the application software in all its different stages: from design to simulation, to testing and debugging, to arrive at commissioning in the field. A fundamental feature of 1tool is integration. Because all the different environments are interconnected to best support development of the application software. Each environment is in fact dedicated to the realisation of a specific function and interacts with the others to offer the designer: -  Greater reliability thanks to real-time error notifications in the design stage; - Reduced development time using the advanced functions offered, first and foremost the new libraries of functional modules specific for HVAC/R; -  Flexibility in terms of software customisation. All these features, an intuitive graphic interface and user simplicity make 1tool an excellent product, responding to th
