Chase Chiller Optimization
Chase Chiller Optimiser (CCO) is a chiller optimisation software that reduces electricity consumption on packaged chillers. Having conducted an extensive trial at hotel chains across the UK, Middle East & US, it is now available for installation at all suitable hotels. CCO is a self-learning parallel third-party chiller control software which improves the energy efficiency of packaged chillers. The software compliments existing chiller controls with its unique parallel control philosophy that enables energy savings, whilst maintaining existing building comfort levels.
Why use CCO?
Augments existing controls
Simple to install, remote commissioning and with no business interruption
Self-learning system delivers tangible energy savings
Software as a service (SaaS)
Reduce operating costs
Lower carbon emissions
Enhanced visibility of chiller operation
FAQ
Is the CCO installation using a temperature setpoint reset
Yes, we use the reset option on the chillers to unload them safely when necessary. As the setpoint is increased thus the chiller unloads.
Can CCO decrease the chiller setpoint?
No, CCO installation is setup only to increase setpoint.
How is control integration between multiple chillers and how is chiller sequencing maintained?
Our controllers are installed into each chiller and connected to their own LAN. The controller outputs the same setpoint offset together in each chiller or to the common sequencer to ensure that the entire plant experiences the same demand thus not increasing load elsewhere and ensuring sequencing strategy is maintained.
Can the CCO system be switched ON and OFF when required for performance comparison and maintenance purposes?
Yes, everything is done remotely and “on off testing” will be done as agreed by all parties. Full visibility provided to all parties involved. Further “Bypass” function is provided on the controllers to facilitate any maintenance or chiller works. This can be set to self-enable or to remain off indefinitely should need arise.
Will the CCO system interfere with existing ambient lockout strategy in place?
CCO can only work when the chiller is working/running and thus will not affect this strategy. As the CCO algorithm only works when there is demand on the system vs achieved setpoint it stands to reason that if the LWT increases and there is no electrical measures demand CCO will automatically revert to “pause”. If one of the machines are locked out it will remain so until changed as per normal operation. The only thing that CCO can do is raise the setpoint marginally thus facilitating our need to unload during demand. CCO constantly monitors RWT & LWT ensuring internal temperatures are maintained
Does CCO replace the existing control strategy?
No, CCO uses the existing control strategy to make savings only when the existing controller deems it fit and safe to do so. Thus, all this occurs within the designed control philosophy of the chiller according to the chiller manufacturer.
What maintenance is required and what are the costs?
There are no annual maintenance requirements however it is good practice to undertake an annual inspection of the installation to verify M&V data and process used.
Will it affect any warranty on the chillers?
No, Chiller warranties are maintained as the interface to the chiller is done using chiller manufacturers provided control inputs.
Does the fitting of the equipment require any interference with the main boards/mechanics of the chiller?
There is no mechanical interface other than fixing temperature probes to the return and flow water pipes. These are surface mounted NTC temperature probes and require no down time or mechanical alterations to the existing plant. Other than that, there is an analogue input for the chilled water reset.
