Ongoing Cost Reductions with Chiller Technology

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.

  • CONNECTIVITY PROTOCOLS
  • 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.

  • OPERATIONAL IMPACT
  • Impact #1
    [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.
    Impact #2
    [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.
    Impact #3
    [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
  • Benefit #1

    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.

    Benefit #2

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

    Benefit #3

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

  • USE CASES
  • Building Energy Management
    Building energy management systems (BEMS) provide real-time remote monitoring and integrated control of a wide range of connected systems, allowing modes of operation, energy use, and environmental conditions to be monitored and modified based on hours of operation, occupancy, or other variables to optimise efficiency and comfort. Building energy management systems can also trigger alarms, in some cases predicting problems and informing maintenance programmes. They maintain records of historical performance to enable benchmarking of performance against other buildings or across time and may help automate report writing. BEMS are often integrated with building automation and control (BAC) systems, which have a broaded scope of operations.
