delivering energy savings of up to 45% and water savings of up to 12%.

New TowerMax is add­on software for Armstrong’s Design Envelope 9521 Integrated Plant Control System. It reduces energy and water usage by harnessing Armstrong’s proven advanced relational control technology (already making significant reductions in energy usage of pumps) to optimise the operation of chiller plant. The set of performance algorithms resident in TowerMax use the flow data from the installed Armstrong Design Envelope (DE) pumps to reduce energy consumption and water usage through more effective heat balance optimisation, and intelligent Best Efficiency Staging of individual items of plant, in line with changes in building load.


At the heart of this solution is the Armstrong DE 9521, which controls the entire plant, including cooling towers, chilled water pumps and condenser pumps in addition to the water­cooled chillers. Lower installed cost is possible with this solution, as Onboard Sensorless technology (already resident in the pumps and other system components) eliminates the need for external sensors and the related installation costs. Operational costs are also minimised as heat transfer across the plant is controlled accurately and optimised, whilst Armstrong’s Active Performance Management technology facilitates real time capacity calculation and condition­based maintenance. The cooling supplied for the building is automatically matched more closely to changes in demand, and the system identifies potential maintenance issues before they impact on efficiency to optimise lifetime performance of the plant.


new control solution, launched by Armstrong Fluid Technology, will enable operating efficiencies of chiller plants to be improved significantly,


WHAT’S NEW SPONSORED BY New Towermax from Armstrong takes chiller efficiency to another level Capabilities of the Armstrong DE 9521 system with


ECO*Pulse and TowerMax include the ability to control either identical or non­identical chillers (in this scenario ‘identical’ refers to chillers of the same make and model, same tonnage, same minimum flow and same interface).


Up to five chillers, five cooling towers and five pumps


can be controlled, and there are no limitations on plant size and cooling capacity. All five chillers can be different sizes, and employing up to two different communication interfaces. Pumps can also be of different sizes.


This solution is available for new installations, or as

Panasonic’s Aquarea J Generation Air to Water Heat Pump: Now Available in Monobloc


• Specially designed for new homes and low energy houses


• R32 refrigerant reaching A+++ energy class (35ºC)


• More capacity in heating & cooling even during adverse ambient temperatures


• Compact design for space­saving possibilities


to Water Heat Pump Range – the extremely efficient J Generation Monobloc with R32 refrigerant. Ideal for new installations and low energy homes, the heat pump packs a high­performance system into one compact outdoor unit.


P


Adapting to the needs of any space The advanced outdoor system provides residential projects with both hot water (DHW), heat for radiators and underfloor heating. With a range of capacities available, from 5kW to 9kW, the J Generation Monobloc offers lower operational cost options than other solutions. The range fully adapts the


anasonic Heating and Cooling is pleased to announce the latest addition to its innovative Aquarea Air


system to the needs of the space, whether it is a new build or a refurbishment, as it can reach up to 60°C water outlet even at ­10oC outdoor temperature. The new J Generation delivers a higher capacity in heating of up to +25%, and in cooling up to +30%.


Compact, space­saving design Thanks to the Monobloc’s neat design, it only takes up a small space outside the property, with the refrigerant sealed in the small outdoor unit, therefore only requiring water pipes inside. An ideal solution for new build projects, the Aquarea J Generation Monobloc can be easily installed in areas with limited space, or even in larger spaces that require a more aesthetically pleasing and unobtrusive design.


The environmentally friendly solution With sustainability at the forefront of Panasonic’s innovations, the Monobloc offers substantial benefits to the end­user and their impact on the environment. Utilising advanced air­to­water technology, the Aquarea range ensures a very efficient, environmentally friendly solution, even in temperatures as low as ­20°C. As well as providing heating and hot water, Aquarea can deliver cooling in the summer.


Remotely control heating and cooling The system is also compatible with the Aquarea Smart Cloud for end­users to


32 BUILDING SERVICES & ENVIRONMENTAL ENGINEER JULY 2020


remotely control the full range of heating and cooling functions, including monitoring energy consumption for both energy and cost­saving possibilities. Furthermore, it can also be connected


to the Aquarea Service Cloud to allow installers to remotely access their customer’s heating and cooling systems, which can increase customer satisfaction by reducing response times as the installers can act and connect from anywhere, thereby saving time and money.


Panasonic’s state­of­the­art, compact


Aquarea J Generation Monobloc unit can be combined with numerous high efficiency accessories for even higher energy savings.
