UK:  Mitsubishi Electric has introduced a new replacement grille for air conditioning units, which automatically lowers the grille on any ceiling mounted cassette up to 4 metres high. Meaning that filters can be cleaned by non-skilled workers to reduce maintenance costs and improves health and safety by removing the need for ladders or towers.

According to the Health & Safety Executive over half a million working days were lost in 2014 due to falls from heights so finding ways to reduce risk is important for everyone.

The PLP-6BAJ grille is easy to fit as a replacement for any of Mitsubishi Electric’s PLA, or standard size PLFY models of 4 way blow cassettes.

Watch this short video demonstrating how the system works.

The grille is available immediately and can be controlled from a PAR31 controller or the remote control that comes with the grille. It is straightforward to use and includes an automatic lowering function to simplify filter maintenance and help maintain energy efficiency.

Keeping the filters clean saves on energy use and reduces the stains and smudges on ceiling tiles caused when filters become dirty.

UK:  Toshiba is all set to raise the bar with the launch of its new groundbreaking energy efficient SMMS-e VRF air conditioning heat pump system.

The latest generation of the company’s industry-leading VRF continues to push the boundaries, by setting a new benchmark for energy efficiency and comes fully loaded with a number of industry firsts such as continuous heating and an innovative hands-free wireless commissioning system.

Compressor

Toshiba’s SMMS-e VRF air conditioning heat pump rotary compressor

At the heart of Toshiba’s new technology is a new rotary compressor, which uses a two-stage compression process for improved efficiency and performance.

Surfaces on the compression vanes are treated with a high-tech Diamond-Like Carbon (DLC), giving outstanding hardness, wear resistance and reliability. This enables a significant increase in compressor rotation speed, resulting in a higher displacement volume of up to 50% greater than the previous generation of VRF systems.

As a result of the new compressors design and improved system controls, the operating temperature range has been significantly extended, and is now -5 to +46C for cooling operation and -25C to +15.5C in heating mode.

Heat Exchanger

The system’s heat exchanger has been completely redesigned, using smaller diameter tubes arranged in three rows in the coil, resulting in a 13% increase in surface area, further improving performance and efficiency.

The capacity of the new generation heat exchanger can be adjusted to match the current load and ambient conditions. The new three-way variable heat exchanger enables the VRF’s control system to automatically select the optimum setting.

Continuous Heating

The SMMS-e breaks new ground in being able to provide continuous heating, with no requirement to stop during defrosts, as with rival systems. This is made possible by the use of a new hot-gas bypass control, which simultaneously defrosts outdoor heat exchanger coils, while allowing the indoor unit to continue operating in heating mode.

Advanced intelligent control

For installers, Toshiba has developed Wave Tool Technology (WTT), a wireless commissioning and performance validation tool that enables engineers to read and write data to the condensing unit using their smart phone, enabling testing and commissioning without removing the unit covers.

This WTT allows service and commissioning engineers to instruct and obtain key system information, simply by touching their smart phone onto the Near Field Communication (NFC) tag located on the outdoor unit. 

The technology simplifies commissioning and reduces the amount of time spent on-site, giving the service engineer the ability to quickly and easily send key system data via e-mail back to the office for analysis.

Capacity

Importantly, the SMMS-e is available in a wider capacity range than ever before. On the smaller end of the scale, indoor units are now available in capacities of 0.6hp, increasing the number of units that can be connected into a system, making it more flexible. Up the scale, outdoor units can offer up to 22hp on a single module platform, due to a newly developed chassis, reducing footprint, pipework and speeding up installation time.

With the new SMMS-e, it is now possible to connect up to 60hp in a single system, with up to 64 connectable indoor units, beating the previous 48hp maximum by a wide margin.

Pipework

Improvements in pipe work and connectivity give significant advantages in terms of system design and application. Maximum total pipe work length for SMMS-e is 1000m (double the previous allowable length), with 235m now the maximum allowable distance between an outdoor unit and the farthest indoor unit, another industry first.

A maximum of 40m between indoor units is enough to cover an entire 11-storey building, expanding the application envelope for Toshiba VRF to larger buildings.

Industry first

Finally, in another industry first, the combined compressor, heat exchanger and advanced intelligent control technologies ensure all of the outdoor units in Toshiba’s new SMMS-e VRF range have an ESEER (European Seasonally Adjusted Energy Efficiency Rating) higher than 7, making it a cut above the rest of it’s rivals.

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

For further information on the CoilPod dust free containment bag, contact Richard Fennelly at richard@coilpod.com
