400-ton heat pump extends York CYK range

USA: Johnson Controls has re-engineered its York CYK water-to-water compound centrifugal heat pump in a smaller, higher efficiency 400 ton capacity for the North American market.

According to Johnson Controls, the York CYK can reduce water and operational costs by as much as 50%, when compared to traditional boiler and chiller applications, and is available with R1234ze or R515B refrigerants. 

It delivers high-temperature hot water up to 170ºF (76ºC) by using two electric-motor-driven centrifugal compressors arranged in series. The design achieves simultaneous hot and chilled water cooling within the same equipment which, according to the manufacturer, makes it 3x to 5x more efficient than a traditional boiler and chiller combination. 

With the addition of a double bundle condenser technology, the CYK can effectively manage unbalanced load conditions – high cooling load with low heating load – in a more compact footprint than alternative solutions, Johnson Controls says.

In addition to reduced carbon emissions, the York CYK is said to deliver significant savings through reduced annual water and operational costs, and a streamlined installation process. 

Johnson Controls says the design is compatible with existing high-temperature hot water heating systems, eliminating the need to replace air handlers and terminal heating devices.

The CYK heat pump model joins the existing 600–2,000 ton product line to extend application to more commercial facilities.
