New YORK YK-EP “Efficiency Plus” Centrifugal Chiller provides energy-efficient savings
MILWAUKEE (March 8, 2016) – The YORK brand of Johnson Controls has launched the YORK YK-EP “Efficiency Plus” water-cooled centrifugal chiller. The chiller achieves five percent capacity and efficiency improvements over the previous model. It utilizes a patent-pending mechanical compression economizer cycle to boost performance over conventional chiller platforms.
The YK-EP uses a YORK OptiSpeed™ variable speed drive, which can accept medium or high voltage power, trimming average annual energy consumption up to 30 percent. The chiller is able to operate with 50 degrees Fahrenheit (10 degrees Celsius) low entering condenser water temperature (ECWT) compared to 75 degrees Fahrenheit (23.9 degrees Celsius) of other chillers, trimming instantaneous energy consumption as much as 50 percent. Additionally, in facilities with multiple YK-EP chillers, energy savings can be accomplished with series-counter flow arrangement. This reduces the compressor work needed on each chiller, cutting system energy use by as much as 8 percent at design conditions.
The YK-EP chiller, capacity of 2,500-3,500 tons, is ideal for large tonnage applications including district cooling or large central plants (universities and airports) and gas-turbine inlet-air cooling. Current customers selected the YK-EP for its ability to reach required capacity levels at real-world conditions and its ability to operate at different low ECWT, which provides significant energy savings.
