York YK-EP Efficiency Plus

Dubai, UAE: Johnson Controls has announced launching the York YK-EP Efficiency Plus water-cooled centrifugal chiller, which has reportedly achieved five per cent capacity and efficiency improvements over the previous model. The chiller is ideal for large-capacity applications, including District Cooling, large central plants and gas-turbine inlet-air cooling, added the company.

Giving details of the product, the company highlighted that the YK-EP chillers have the most compact configuration in their class and a 15% smaller footprint than competing chillers, thereby reducing the total cost of ownership, and releasing premium space for commercial gains. The chillers, the company revealed, use a York OptiSpeed variable-speed drive, which can accept medium- or high-voltage power, saving electrical infrastructure costs and cutting down average annual energy consumption by up to 30%. The company also mentioned that the chillers are equipped with the York OptiView control panel for enhanced chiller control and Building Management System (BMS) integration.

As the chillers can reach the required capacity levels at real-world conditions and operate at low ECWT, the company said that they provide significant energy savings. In facilities having multiple YK-EP chillers, system energy use can be decreased by as much as eight per cent at design conditions by piping the chillers in a series-counterflow arrangement, reducing the compressor work needed on each chiller and driving up energy savings, added Johnson Controls.

“The chillers utilise a patent-pending mechanical compression economiser cycle, which couples a primary compressor with an auxiliary economiser compressor to make it more efficient than single stage chillers,” explained Vivek Apte, Regional Product Director, Chiller Solutions, Middle East and Africa, Johnson Controls. “While the chiller is able to operate with low entering condenser water temperature (ECWT) down to 55°F (12.7°C) compared to 75°F (23.9°C) for other chillers, trimming instantaneous energy consumption by as much as 50 percent – the chiller is also capable of operating efficiently with warm ECWT that prevails in this region, specially during summers,” added Apte.
