Chosen for its efficiency, safety, availability, low environmental impact and cost, nonflammable R-1233zd(E) has an ultra-low GWP of 1 and is readily available from refrigerant manufacturers.
Johnson Controls used a holistic approach to system design and engineering, optimising every component around a carefully selected next generation refrigerant for ultimate performance.
The YORK YZ chiller uses an integral, variable speed drive and advanced magnetic bearing technology that features a single moving assembly suspended in a magnetic field that does not require lubrication.
This technology requires 80% fewer moving parts than traditional oil- or refrigerant-lubricated drivelines. The result is enhanced reliability, reduced maintenance and improved efficiency. Compared to traditional fixed-speed oil-bearing chillers, the YZ delivers up to 35% annual energy savings.
The YZ chiller can deliver significant energy savings and lower operating costs by taking advantage of the off-design conditions where chillers operate 99 percent of the time.
The YZ operates with entering condenser water temperature as low as 40°F (4.5°C), providing enhanced performance in every operating condition and the widest operating envelope in the industry.
The YORK YZ uses an optimised single stage design to provide industry-leading real-world energy efficiency.
The chiller can also operate with condenser temperatures below the evaporator temperatures, eliminating the need for a water-side economizser, which simplifies the system, requires less mechanical room space and saves money on components, piping, controls and maintenance.
The YZ chiller brings together groundbreaking YORK® innovations refined over decades of real-world use to create a revolution in chiller design and optimisation. It represents a solution from the chiller experts, who like to think of the YORK® YZ chiller as tomorrow’s chiller, available today.
