Johnson Controls has launched the YORK YK-CP Centrifugal Chiller designed to deliver high-efficiency performance, meet stringent sustainability standards and aid in the decarbonisation of large commercial buildings.
Available in 2,000 to 3,000 tonnes, it is optimised specifically for the use of the ultra-low GWP refrigerant R-1234ze(E) without requiring a larger chiller footprint or sacrificing on efficiency.
It can be equipped with an optional variable-speed drive for optimal utilisation at both full and part loads, as well as under design and off-design conditions at varying ambient temperatures, resulting in operation up to 30 per cent more energy-efficient than conventional chillers.
That additional efficiency can be equivalent to cutting CO2 emissions by over 500 metric tonnes or removing over 100 passenger vehicles from the road each year, per chiller.
Associate product manager, global centrifugal chillers, Applied Equipment, Johnson Controls, Greg Shirk, said YORK YK chillers have with an installed base that spans tens of thousands of installations in over 100 countries.
“YORK YK chillers have built a reputation for delivering systems that are fully optimised for their environments and that have proven to operate more efficiently in real-world conditions,” he said.
“The YK-CP model builds upon this legacy, allowing building owners to reduce costs and carbon impact with this long-term solution.”
An evolution of the successful, high-efficiency YK-EP centrifugal chiller, the YK-CP offers real-world efficiencies as low as 0.15 kW/ton (23.4 COP).
This is due in part to the system’s high-efficiency economizer, which improves system efficiency and reduces operating costs.
Further, it features heat exchangers that use JCI's proprietary, falling film evaporator design that allows the unit to operate more efficiently and with up to 40 per cent less refrigerant charge than conventional chiller designs.
In addition to high-efficiency operation, the YK-CP features the proven OptiView Control Panel with updated software, making it easier than ever to manage chiller operations—securely and efficiently.
The updated panel interface helps streamline operations by providing operators with the information they need in a clear, accessible format while increasing efficiency and minimizing errors.
It also makes it easier for staff to learn and operate the system, and provides the tools and insights needed to work both smarter and more efficiently.
The YK-CP is configured to optimize a large facility’s cooling needs. Designed with modularity in mind, the YK-CP has many different sizes of shell sets available while holding many key dimensions of the unit in place, which benefits facilities that need more than one cooling condition met.
Additionally, the YK-CP can be equipped with different heat exchanger lengths to save on up-front cost while configuring the best performing unit for each cooling need.
The YK-CP can be ordered to deliver the exact capacity required—with a variety of options including heat exchangers, gears and open-drive motors—minimising the need to order a larger-size chiller package than might be necessary.
Once on-site, commissioning costs are also reduced, thanks to faster start-up and integration with existing controls and/or building automation systems.
Additional YORK YK-CP Centrifugal Chiller features include:
- Compared to chillers that can only use a minimum 75 F (24 C) ECWT, a YK-CP chiller can operate with ECWT as low as 45 F (7.2 C), reducing instantaneous energy consumption as much as 50 per cent.
- Compared to other chillers in the market using low-pressure refrigerants, the YK-CP features a 22 per cent smaller footprint, which can simplify transport and installation and further reduce carbon emissions.
- YK-CP chillers combine available OptiSound Control alongside optional VSD technology to minimize gas-flow disruptions that cause noise.
The ISASecure® certified YORK® Chiller Access Manager provides secure access to chiller controls. This helps mitigate the risk of unauthorized access, safeguarding equipment operations and minimizing the potential for downtime due to security breaches.
