Air Movement, Fans & Ventilation
Designed for high seasonal efficiency
IN A WORLD where global warming is driving ever increasing demands on air-conditioning, long-term sustainability and efficiency have become key elements of new equipment design.
In response, Temperzone has designed the Econex OPA, an innovative range of variable capac- ity R32 inverter rooftop packaged systems. These systems are designed to have exceptional seasonal energy efficiency through the implementation of leading system software and componentry.
Temperzone’s innovative Econex inverter R32 rooftop package units have been designed to assist organisations in their carbon reduction efforts.
The combination of R32 refrigerant and lower refrigerant charge enables this range to achieve reductions in refrigerant related GWP (Global Warming Potential) of between 71-79% per kW of cooling or heating, when compared to current R410A models.
Increased energy efficiency and effective load matching are key design aspects of the Econex OPA range. As standard, all unit’s feature EC plug fans and EC condenser fans, dual electronic expansion valves and inverter compressors.
Temperzone’s UC8 intelligent control logic enables the synergistic control of these compo- nents for significantly improved seasonal energy efficiency when compared to fixed speed solu- tions, achieving total cooling seasonal perfor- mance factors as high as 6.414 (OPA 250).
Temperzone’s Inverter compressor control enables exceptional comfort conditions with precise load variation response and an impres- sive frequency range of 16 -100 per cent.
High response levels to current load conditions are further guaranteed using electronic expan- sion valves and variable speed control of the indoor and outdoor fans.
“TEMPERZONE’S INVERTER COMPRESSOR CONTROL ENABLES EXCEPTIONAL COMFORT.”
OPA Econex units also feature wide heating and cooling capacity ranges, enabling the delivery of increased capacity in periods of peak load. For example, the OPA 350 will deliver a cooling capac- ity 30 per cent above its normal rating and a heat- ing capacity 27 per cent above its normal rating.
Econex OPA incorporates new features to ensure simple cost-effective installation and ser- vicing, and improved product longevity.
For cost-effective installation, unit footprints have been reduced by up to 22 per cent when compared to current R410A models.
These units are now easier to install with a new bank of terminal blocks dedicated to customer wiring, whether you are using a thermostat, high-level BMS or low-level BMS.
There is now convenient internal access with hinged access doors for the compressor and electrical areas as well as the supply and return air chambers.
To further minimise weathering the compres- sor compartment has been isolated from the fan chamber and a new sloping base tray has been incorporated into the outdoor section.
With the axial fans rated to provide at least 125Pa of static, Econex OPA can be installed in areas where exhaust air is required to be ducted away.
The first release of the Econex OPA range con- sists of four models with nominal cooling capac- ities ranging from 25kW to 56kW - the OPA 250, 350, 450 and 560.
Multiple handing configurations will be available, these include standard and opposite handing in both horizontal and downward dis- charge options.
Both economiser and fresh air will be avail- able as standard options. These products join our wider Econex product series which cur- rently features 14kW to 35kW Econex ducted split units.
