Johnson Controls’ York YZ magnetic-bearing centrifugal chiller won a 2021 CRH Innovation Award at the 2021 China Refrigeration Exhibition at Shanghai New International Expo Center.
The YZ chiller is optimized around R-1233zd(E), a low global warming potential (GWP) refrigerant, to provide high efficiency. It operates with entering condenser water temperature as low as 40°F (4.5°C), which the company says provides enhanced performance in every operating condition. The chiller also has the widest operating envelope in the industry, according to Johnson Controls. The chiller is available from 165 to 1,350 tons in cooling capacity.
