In an awards ceremony that took place in Tokyo on December 2, Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems), a part of Mitsubishi Heavy Industries (MHI) Group, has received a Minister of the Environment Award for Climate Action 2024 for development of its JHT-Y/JHT-YI series of large-capacity centrifugal chillers adopting the HFO-1234yf refrigerant with a low GWP. The award, sponsored by the Japanese Ministry of the Environment, was presented in the Technological Development and Commercialization category.
The Minister of the Environment for Climate Action Award program was renewed in 2020 to reflect recent trends in climate change measures and succeeded the Environment Minister’s Awards for Global Warming Prevention Activity, which had been held since 1998. The awards are given annually to individuals or groups having made noteworthy contributions to climate change mitigation (measures to curb greenhouse gas emissions) and accommodation to climate change (measures to avert or reduce impacts from climate change). This 2024 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 that adopt a low-GWP refrigerant; and in 2021, the company garnered the award for development and promotion of an air-to-water type heat pump using a low-GWP refrigerant.
The constant-speed JHT-Y and inverter-equipped JHT-YI are new series for large-capacity centrifugal chillers launched in June 2022.
