MHI large capacity chillers win environment award

JAPAN: Mitsubishi Heavy Industries has received a Japanese government climate action award for its JHT-Y/JHT-YI series of large-capacity centrifugal chillers using R1234yf.

The Minister of the Environment Award for Climate Action 2024, which is sponsored by the Japanese Ministry of the Environment, was presented at a ceremony in Tokyo on December 2.

This latest award is MHI Thermal Systems’ third to date: in 2019, the company received an Environment Minister’s Award for its high-efficiency centrifugal chiller ETI-Z series using R1233zd(E) and, in 2021, MHI garnered the award for development and promotion of its Q-ton Circulation air-to-water heat pump, using R454C.

The constant-speed JHT-Y and inverter-equipped JHT-YI were launched in June 2022 and offer capacities ranging from 300RT to 5,400RT. They were the first centrifugal chillers with capacities up to 5,400RT commercially offered in Japan with a low-GWP refrigerant.
