MHI to launch R1234yf chillers up to 5,400RT

JAPAN: Mitsubishi Heavy Industries Thermal Systems is set to launch a new series of large capacity centrifugal chillers from 300 to 5,400RT on the low GWP refrigerant R1234yf. 

The constant-speed JHT-Y and the inverter-equipped JHT-YI are said to be the first centrifugal chillers with capacities up to 5,400RT offered commercially in Japan to feature a low-GWP refrigerant. The constant-speed model has a rated COP of 6.9.

Together with MHI’s ETI-Z series of centrifugal chillers in the small-to-medium capacity range launched in 2015, MHI Thermal Systems will now offer a full lineup of low-GWP refrigerant models in variations spanning from 150 to 5,400RT.

The new series, which will be available in Japan in June, is also said to adopt an all-new type of compressor. Increasing the variety of models enables selection of the optimal compressor to match the output of the chiller, to realise high performance throughout the capacity range.
