The Challenge

The existing chiller had proved unreliable over the previous 3 years of operation with frequent refrigerant leaks resulting in ineffective air-conditioning for the building.

The Solution

• Johnson Controls developed a turnkey solution centred around their highly energy efficient YORK® Tempo (YLAA) air cooled liquid chiller. • Johnson Controls demonstrated that the YORK® Tempo unit offered superior performance and energy efficiency over similar units from other manufacturers. • Johnson Controls on-site survey revealed an improper maintenance regime had led to premature demise of the existing chiller and their bespoke solution included a comprehensive 5 year maintenance scheme.

Data Collected
Energy Cost Per Unit, Fridge Temperature, HVAC ( heating, ventilation, air conditioning), Leakage, Maintenance Requirements
Operational Impact
  • [Management Effectiveness - Centralized Management]
    Johnson Controls’ full-service offering which includes expertise in energy efficiency, HVAC products, project management and installation and maintenance services enabled Fiserv to use one supplier for the complete project.
  • [Cost Reduction - Overall]
    By selecting the YORK® Tempo, Fiserv benefited from class-leading technologies, a compact footprint and superior energy efficiency; all of which optimise the total cost of ownership.
  • [Cost Reduction - Energy]
    With the YORK® Tempo running at part load for the majority of its operational life, significant energy savings were delivered to Fiserv, thanks in part to its Eurovent A class1 efficiency.
Quantitative Benefit
  • The YORK® Tempo range of chillers use HFC 410A refrigerant which has zero Ozone Depleting Potential and uses up to 50% less refrigerant charge than comparable chillers.

  • The YORK® Tempo is offers superior attenuation with a sound level as low as 54 dB(A) at 10 metres.

  • The new YORK® Tempo was installed and commissioned within three days of delivery to site.
