UK:  Fujitsu has introduced a range of factory engineered electronic expansion valves (EEVs) and a control unit as a DX kit, to enable other manufacturers’ air handling units (AHUs) and fan coil units (FCUs) to be incorporated into a Fujitsu VRF air conditioning system, or be connected to a dedicated Fujitsu VRF outdoor unit as a one to one system, to heat or cool outside air for building ventilation.

Arrangement as part of a Fujitsu air conditioning VRF system

The three EEVs in the range – UTP-VX30A, 60A and 90A – support a wide range of capacities and a variety of control options, with temperature being closely regulated by multiple sensors located in the AHU or FCU.

Connectable capacity ranges from 5kW up to 50kW, with two EEV units connected in parallel on larger 33kW, 40kW & 45kW systems.

Control of the DX kit/AHU system can be either from a Fujitsu VRF system, a central controller or an external BMS system.

To train engineers on the new units, Fujitsu has set up a working DX kit system in its training facility at Elstree, and added a DX kit course to its training programme. DX kits can also be selected via the Fujitsu Design Simulator software program which also has a dedicated training course available.

Says Fujitsu product and specification manager Colin Goode: “We believe these new kits will prove very popular with contractors and specifiers alike, as they expand the application of our VRF systems enormously and add flexibility to the system design process as a whole.”

Product Review:  BITZER, the world’s largest independent manufacturer of refrigeration compressors has launched a new cutting-edge air-cooled condensing unit. The new energy-efficient ECOSTAR LHV7E also complies with the 2016 EU Ecodesign Directive. 

The new condensing unit offers operators unrivalled energy efficiency, which is essential in an environment of rising energy prices. The low-maintenance, easy-to-use device also boasts reliable, low noise operation and simple installation.

Modern fans and compressors

The integrated EC fan of the ECOSTAR LHV7E reduces the noise level and energy consumption significantly. The optimised control allows the user to adjust the speed of the fans and the ECOLINE VARISPEED compressor at any time for more energy-efficient operation. The optimised mini-channel condenser also improves eco-efficiency: compared to the older ECOSTAR models, the LHV7E requires a lower refrigerant charge while offering higher heat exchange.

The LHV7E is also extremely quiet: its low noise EC fans feature sound-optimised airflow and the compressor is located inside a sound-damping housing. When the cooling load is normal, the system can be operated in ECO or low-sound mode. Thanks to its energy-optimised, quiet operation, the LHV7E is the right condensing unit today for the applications and challenges of tomorrow.

Remote control and simple maintenance

The new ECOSTAR condensing unit optimised Lodam controller with newly integrated Bluetooth technology has proven to be a helpful feature, ensuring technician-friendly operation of the ECOSTAR and working seamlessly at a distance of 30 meters away.

The ECOSTAR LHV7E condensing unit can be controlled and serviced remotely via an Ethernet connection for networks or the Internet, Modbus RTU and Bluetooth access using BITZER’s BEST software. There’s also a display for operation, which comes integrated into the controller housing and offers optimised menu access. The BEST software or an optional retrofit display provides users with full access to all the menu options.

Another new feature is that up to four ECOSTAR condensing units can be linked together via the Modbus. Together the condensing units form an ECOSTAR control network and, in optimised interaction, control the temperature of a cold store without having to be connected in the refrigerant circuit.

The control electronics of the LHV7E are fully wired in the factory and come ready for operation, facilitating fast installation of the condensing unit on-site. To simplify maintenance of the device, BITZER has optimised access to the important components: each of the two casing parts can be opened with a captive screw. The terminal box, the filter drier, the sight glasses and the oil separator can easily be accessed in no time from the outside.

Suitable for lots of applications

The ECOSTAR LHV7E is available in six variants, four of which offer a capacity of up to 42 kW (0/32/20@R134a). Depending on the model, it’s compatible with the refrigerants R134a, R404A, R507A, R407A, R407C and R407F, which means BITZER enables a whole host of applications for this condensing unit. With its compact design, the condensing unit also fits into smaller engine rooms, while the robust housing also makes it suitable for outdoor use. The integrated winter start feature allows the compressor to be started even in winter when the ambient temperature falls below the saturated suction temperature.

The BITZER LHV7E condensing unit comes standard with an integrated frequency inverter and filter drier. Optional features include an oil separator with check valve, oil monitoring and an additional check valve for installation in low ambient temperatures.

USA:  Now we've all been there. Called out to a busy bar and restaurant, kitchen or sales floor only to discover that a plug-in (integral) fridge has broken down due to a blocked condenser coil. You advise the client that you need clean the coil and blow out the condenser with nitrogen but it's going to make a bit of a mess. Not ideal when working in a busy food preparation environment, and I'm sure that you've been told many a time to come back when we're not busy.

It's also well known that frequent maintenance of condensers on commercial plug-in (integral) fridge-freezer appliances can result in up to 50% savings in running costs, as well as prolonging the life of compressors.

Now U.S. Company COILPOD has come up with a unique, yet simple solution for engineers to carry out task of cleaning self-contained condenser coils in both a mess-free and environmentally-friendly way.

How it works

The CoilPod transparent bag, which measures 28in wide x 13in deep x 18in high, slips over the coil structure creating a dust seal. A standard wet/dry vacuum can then be used to remove debris from the coils through two ports in the bag’s surface. The bag entraps the removed debris during the cleaning operation protecting the environment outside the bag from undesired contamination.

Watch CoilPod in action

UK:  Resource Data Management (RDM), leading HVACR control and remote monitoring solution provider, has announced two major product launches. The dmTouch, their colour HD touch screen management system front end now features a 10.1” screen. Further optimising the user experience the larger screen makes it even easier to monitor and control sites from one central point. The launch of the new screen is coupled with a number of software enhancements including faster browsing, optimised responsive interface, heightened graph performance, a new algorithm to further improve the data manager’s ability to highlight energy waste and enhanced language support for The Data Builder (TDB) - RDMs PLC software.

A key addition to their Intuitive range is the new Intuitive Transcritical Superpack Controller. Designed for the retail and industrial refrigeration markets the Intuitive Transcritical Superpack Controller is a versatile expandable controller intended for HT/LT CO2 Pack, Gas Cooler and HT/LT Oil monitoring and control. Each section is individually selectable and can be set to disabled if not required. The controller can be expanded using up to 10 Expansion Modules, consisting of the Intuitive Stepper Expansion or Intuitive IO Expansion module range. Building on the success of RDMs existing Transcritical software solutions the new Intuitive Transcritical Superpack controller has similar features and functions as the other controllers in the Intuitive Control range, with a number of key enhancements.

RDM Intuitive CO2 Transcritical Superpack Controller

For Gas Cooler and receiver control the Intuitive Transcritical Superpack controller heightens flexibility, giving users the ability to select between 0-10V, 4-20mA, 0-5v, 0.5-4.5v or 0.5-9.5v or stepper control for either or both of the two CO2 valves or any of the variable outputs, such as fan speed control. Furthermore this can be done using the same application software, allowing for the control of either HT/MT valve using one piece of hardware.

The new Intuitive Transcritical Superpack Controller software application is a single piece of software that can be configured to control and monitor the earlier mentioned applications. Using the additional Intuitive expansion boards will allow them to expand the number of control stages and/or introduce an oil management strategy, facilitating 5 sections of control and monitoring - Low Temperature compressor, High Temperature compressor, Gas Cooler, Oil for LT compressors, Oil for HT compressors. As a result the customer has the flexibility to quickly and easily build a solution that specifically meets their needs.

Toby Peters, Senior Group Managing Director, Dearman

When asked about his approach to product development Andrew Chandler said ''It may sound like common sense but when I started RDM, before we designed any products, I asked retailers an obvious, but often unasked question. What did they want? In doing so we gained their unique insight and confirmed our suspicions - they were frustrated at being locked in by proprietary systems and by products that despite their expense frequently required maintenance and came with a short life span. Our product development is driven with the customer at the heart of the process from start to finish. We are passionate about helping our customers be as energy efficient as possible, this begins with ensuring that the products they install are effective with a long life span and is why we offer a 5 year warranty on many of our products.
