Mitsubishi Heavy Industries Thermal Systems Ltd will launch a new series of large-capacity centrifugal chillers in June using the refrigerant HFO-1234yf.

The series will have two models: the constant-speed JHT-Y and the inverter-equipped JHT-YI.

Both new models feature capacities ranging from 300 to 5,400 refrigeration tonnes (RT) with the maximum capacity representing a 400 RT increase over the “GART-ZE/ZEI” series launched in 2017.

The JHT-Y and JHT-YI are the first centrifugal chillers with capacities up to 5,400 RT offered commercially in Japan to feature a low-GWP refrigerant. Together with the ETI-Z series of centrifugal chillers in the small-to-medium capacity range launched in 2015, MHI Thermal Systems will now offer a full line-up of low-GWP refrigerant models in variations spanning from 150 to 5,400 RT.

The new series also adopts 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 realize high performance throughout the capacity range.

The constant-speed model features a rated COP(Note4) of 6.9, which, as before, provides one of the world’s highest levels of energy efficiency together with compact size.

Chillers in the new series can also be controlled with supreme precision using the latest microcomputer operation panel, and both the constant-speed and inverter models can respond to diverse applications including low-temperature, heat-pump and heat-recovery specifications.
