Does energy efficiency and the cost of running a refrigeration system play on your mind?
Climalife UK
With energy costs rising in the UK, there are products that can help to improve energy efficiency through the control and regulation of HVACR systems. Products such as a range of components from manufacturer CAREL, that can monitor temperature and pressure in a system, helping to regulate the refrigerant flow. These can be ideal for many cooling systems. The components have been demonstrating their benefits for many years with current refrigerants and are also available for most of the low GWP refrigerants that are now being proposed for future use.
Let’s take a look at some of the features and benefits of the components.
Programmable controllers
The range consists of iJW Refrigeration Controllers, IR33 Universale controllers, pCO Sistema and Sensors.
iJW Refrigeration Controller with built-in “wizard”
iJW is a new range of controllers for refrigeration, aimed at refrigeration engineers operating in the distribution channel. Suitable for both new installations and retrofits, iJW has been designed to simplify the replacement and c
onfiguration of the controller on display cabinets, bottle coolers, plug-ins, chest freezers and in many other applications.
Designed for both field replacements and new installations, it is simple to use thanks to native Bluetooth® and NFC connectivity. Installers can use their smartphone with APPLICA for configuration, testing and maintenance of the controller, while the end users can optimise everyday tasks (such as recording HACCP data) with CONTROLLA.
ir33 Universal Temperature Controllers
These instruments are used to control temperature, in air-conditioning, refrigeration and heating units. ir3
3 controllers are versatile and can act as a thermostat, allowing for lower energy consumption and a reduction in polluting emissions.
pCO sistema
A solution for managing HVACR applications and systems. It consists of programmable controllers, use
r interfaces, electronic expansion valves, inverters with DC technology and communication interfaces, remote management systems to offer OEMs working in HVACR a control system that is powerful yet flexible and can be easily interfaced to the most widely used Building Management Systems. A complete solution made-to-measure for the new generation of high efficiency units: chillers, air-conditioners, heat pumps, shelter units, rooftop units, compressor racks and air handling units. pCO sistema guarantees reliability and can be modified to allow it to differentiate itself to suit both refrigeration and air conditioning units.
Sensors
range includes temperature and humidity sensors for wall mounting, duct mounting and industrial e
nvironments. Due to the development of technical solutions in sensors they have excellent accuracy making them reliable to measure temperature at a low cost.
Electronic Expansion Valve technology
Electronic Expansion Valves in the CAREL range have been designed to meet any cooling capacity requirements up to 2000kW in air conditioning and refrigeration applications. Electronic expansion valves provide superior control of the flow of refrigerant into an evaporator compared to thermostatic expansion valves.
They do this by responding to signals sent by an electronic controller which in turn controls a small motor which is then used in order to open and close the valve port. One of their main advantages is the energy saving available due to the ability to operate at low condensing pressures and allow precise superheat control. This in turn creates improved efficiency of the refrigeration cycle.
Electronic Expansion Valves allows reliability over time due to their design being of high quality. Precise control of cooling systems is guaranteed, helping the increase of energy saving.
The primary function of Expansion Valve Drivers (EVD) is to ensure stable superheat 
at the required level. These drivers guarantee installation flexibility as well as managing many different refrigerants in any application. EVD’s are available as ‘single’ or ‘twin’ drivers, the latter able to control two valves independently, which is most commonly used in refrigerants. A powerful removable graphic display can be used to configure the driver, which provides clear and immediate information on the operating status of the system.
The CAREL product range continues to be well received by Climalife customers who appreciate the performance and reliability of the products, in particular enjoying how well they control superheat, which of course helps towards the efficiency of the system and reduced energy consumption.
“CAREL offers products that integrate well into existing systems, this is beneficial for customers/contractors who are unable to obtain previously used parts due to them becoming obsolete and parts availability. This makes it an extremely popular product amongst the service sector of the industry. For new installations CAREL offers an innovative product range which maximises ease of install with performance and efficiency, this contributes to the popularity of these parts” says Amy Gittoes, Northern Regional Sales Manager of Climalife.
