 | Airedale International Air Conditioning has launched upgraded editions of its Ultima compact chiller and condensing ranges (30-150kW), optimised for use with R410A refrigerant. The units are compact with single or dual circuit variants, offering regular quiet and extra quiet sound variants. The latest generation edition can achieve an EER (Energy Efficiency Ratio) of up to 3.6 and an ESEER (European Seasonal Energy Efficiency Ratio) of up to 4.7 (Ultima compact chiller range). |
The R410A range is suitable for a variety of environments including data centres, retail, manufacturing and leisure and is available in 5 case sizes. The chiller range is offered with a selection of full hydraulic pump options, and buffer tanks to reduce installation time, footprint and operating costs.
Key features of the updated models include:
Compressors
For increased efficiency and reliability, both ranges utilise next generation DSH scroll compressor technology.
DSH compressors have low vibration levels, and are focussed on part-load energy efficiency, lowering applied costs and complete robustness.
The Intermediate Discharge Valves (IDV) avoid over compression and extra effort by motors during part-load operation, reducing power consumption, increasing energy efficiency and SEER from 3 to 10 percent.
R410A
Both the Ultima compact chiller and condensing unit range have been developed for use with R410A. With the higher heat transfer capabilities of R410A, it is designed to increase system efficiencies and is less susceptible to efficiency losses due to pressure drop when compared with R407C.
Axial EC fans
Electronically commutated axial fans give increased performance for reduced power input and are up to 80% more efficient than an AC fan at part-load.
Electronic Expansion Valves* (EEVs) - chiller range only
EEVs are included on all Ultima Compact Chillers as standard. EEVs ability to maintain control of the suction superheat at reduced head pressures provides significant energy savings. This can result in an EER increase of up to 30%.
Remote Electronic Expansion Valves (REEVs) – condensing unit range only
The Remote Electronic Expansion Valve (REEV) brings the efficiency and control of electronic expansion valves to a split system, providing stable and accurate control of the refrigeration systems superheat.
REEV enables Ultima Compact Condensing Units to be matched with any manufacturer’s new or existing air handling unit in a 1-1 circuit match, regardless of size.
Benefits of REEV include improved efficiency of up to 30%, versatility for a greater selection tolerance, remote intelligent configuration, providing ultra-stable system operation, and reduced cost of installation.
Callum Teahan, Lead Mechanical Engineer – Product Development, said: “With the next generation Ultima ranges, we have examined every single component to find ways of increasing performance, reliability and overall system efficiency. The new products bring all of this advanced technology and know-how together in a compact, versatile platform.”
