Systems of monitoring and supervision carry out a role key in the management incorporated of the systems HVAC/R. These are essential instruments for continuously and effectively controlling the status of field devices and recording temperature and events in compliance with HACCP regulations. They can perform scheduled actions (e.g. lights on/off, etc.) and optimise the organisation of maintenance operations through effective alarm management. The immediate signalling of alarms by SMS, e-mail and/or fax means the installation is always under control, while the remote system can be used to resolve several problems quickly, without need to go on-site, ensuring economic savings and faster response times. The system offers various reporting options, including standards-compliant print-outs at programmable times. In addition, critical situations can be highlighted relating to the trend in values such as temperature, pressure and power consumption, comparing values...

CAREL released its first programmable controller over twenty five years ago, and today has the widest range available in the sector.   pCO sistema represents CAREL’s response to the demand for controllers with programmable logic for HVACR applications. Reduced assembly and wiring times (DIN rail mounting);   Real time management of the fastest transients, using powerful microprocessors ; Possibility to save events (alarms, temperature, pressure,…) even for extended periods, in the flash memory; Flexible and customizable appearance; Simple connection to more commonly used communication standards using the resident multi-protocol software; Considerable flexibility in defining the functions and algorithms, using the 1tool development package.   All easily interfaced to the most widely-used Build Management Systems , or integrated into the property supervisory system.

After Carel's great success with the ExV Electronic Expansion Valve w e hereby wish to inform you that the new CAREL valve selection tool, ExVLab, is now available on the KSA. Entirely done online and with no need to download and install any software, this easy to use instrument guides you through the selection of the appropriate ExV for your application by simply inserting the main parameters of interest (refrigerant, cooling capacity, condenser temperature etc..). The new tool is a web application accessible from PCs and mobile devices, at the following link:   https://exvselectiontool.carel.com/ExVLab/ , currently available for Google Chrome, Firefox, Safari and Internet Explorer 10.

i-A.C.Systems , as Carel's VAR (Value Added Reseller), offers increasingly advanced control solutions in the field of parametric controllers for HVAC/R applications. Specific commitment is dedicated to universal controllers , which provide the user a powerful and flexible instrument that can easily be configured. Starting from extremely simple control strategies the user can, by modifying just a few parameters, adopt control algorithms that are much more sophisticated and innovative, for example PID (Proportional Integral Derivative) with AutoTuning. The comtool software can be used to configure the parameters on the controllers directly from a personal computer. Simple installation is also an important factor, both as regards assembly and wiring, using standard templates and quick connectors. Finally, all universal controllers can interface with CAREL supervisory systems and open supervisory systems.

The right level of humidity in room affects the level of comfort perceived by people and reduces the risk of respiratory illnesses. Humidification is generally required during the winter period, as increasing temperature with a heating system decreases its relative humidity leading the air condition at a very low comfort level. Low air humidity levels cause dryness of the throat, chapped skin and lips and sore eye, increasing the probability of falling ill. Comfort depends on the relative humidity: in winter, even if there is fog outside (100% relative humidity), the building heating systems increase the temperature of the air to a comfortable level, around 20 °C. In this way, the relative humidity dec reases to valu es even as low as 10-30%, which are perceived as dry air. Consequently the skin on the hands crack s and the same occurs on the lips. As well as being an unpleas ant sensation, the nose and the throat are "dry" , thus favouring the typical illness of...
