TOKYO, Dec 3, 2024 – (JCN Newswire) – – Mitsubishi Heavy Industries Thermal Methods, Ltd. (MHI Thermal Methods), part of Mitsubishi Heavy Industries (MHI) Group, has acquired a Minister of the Surroundings Award for Local weather Motion (WA:) 2024 for improvement of its JHT-Y/JHT-YI collection of large-capacity centrifugal chillers adopting the HFO-1234yf refrigerant with a low GWP(1). The award, sponsored by the Japanese Ministry of the Surroundings, was introduced within the Technological Improvement and Commercialization class. An awards ceremony befell in Tokyo on December 2.
The Minister of the Surroundings for Local weather Motion Award program was renewed in 2020 to replicate latest developments in local weather change measures and succeeded the Surroundings Minister’s Awards for World Warming Prevention Exercise, which had been held since 1998. The awards are given yearly to people or teams having made noteworthy contributions to local weather change mitigation (measures to curb greenhouse gasoline emissions) and lodging to local weather change (measures to avert or scale back impacts from local weather change). This 2024 award is MHI Thermal Methods’ third up to now: in 2019, the Firm acquired an Surroundings Minister’s Award for its high-efficiency centrifugal chiller ETI-Z collection that undertake a low-GWP refrigerant(2); and in 2021, the Firm garnered the award for improvement and promotion of an air-to-water sort warmth pump utilizing a low-GWP refrigerant(3).
The constant-speed JHT-Y and inverter-equipped JHT-YI are new collection for large-capacity centrifugal chillers launched in June 2022. Each fashions within the collection undertake the HFO-1234yf refrigerant with extraordinarily low environmental affect (GWP beneath 1) and the capacities starting from 300 to five,400 refrigeration tons (RT)(4). The JHT-Y and JHT-YI are the primary centrifugal chillers with capacities as much as 5,400 RT commercially provided in Japan with a low-GWP refrigerant. With a newly designed compressor, excellent effectivity has been achieved: the constant-speed mannequin to realize a most rated COP(5) of 6.4, the inverter-equipped mannequin achieves an IPLV(6) of 8.8 and a most half load COP of 24.9. A smaller compressor measurement, along with the optimized centrifugal chiller construction format, additionally contributes to the efficient use of the house, enabling clean set up from current tools. The alternative of an current tools utilizing a higher-GWP HFC (hydrofluorocarbon) refrigerant with the JHT-YI can scale back annual vitality consumption and CO2emissions by roughly 65%(7), contributing considerably to mitigating environmental impacts. The JHT-Y and JHT-YI fashions are additionally adaptable to a variety of purposes: air-conditioning, heating, in addition to low-temperature and heating processes in beverage crops, and so forth.
The HFO-1234yf refrigerant, which can also be utilized in automobile air-conditioners and merchandising machines, has a GWP of beneath 1 and ODP(8) of zero, and is categorized as non-Freon refrigerant based on Japan’s Revised Fluorocarbons Restoration and Destruction Legislation(9). For these causes, it’s not topic to this Legislation that regulates the Fluorocarbons’ emissions into the ambiance, restoration, and destruction after utilization. Regarding an tools with higher-GWP HFC refrigerant together with HFC-134a, which was broadly used earlier than the revised laws took impact, it has been made obligatory to cut back in each their manufacturing and utilization volumes because it has a major affect on international warming. In 2025 and onward, it’s scheduled that the laws on the availability of apparatus with higher-GWP refrigerants to the market can be tightened additional within the Japanese market, due to this fact, at present the calls for for the tools with low-GWP refrigerants, ex. the JHT-Y/JHT-YI collection, are rising and earlier upgrading is required out there.
MHI Thermal Methods is Japan’s main producer of centrifugal chillers, having delivered quite a few models for district cooling/heating, manufacturing unit air-conditioning, and so forth. Going ahead, the Firm will proceed to give attention to creating high-performance merchandise utilizing low-GWP refrigerants masking – along with the small and medium-capacity ETI-Z collection – a capability span of 150 to five,400 RT, as its manner of contributing to environmental safety on a world scale.
(1) GWP: international warming potential. CO2 is assigned a GWP of 1. The decrease the GWP issue, the much less affect on the surroundings.

(3) For additional data, consult with the next press launch: https://www.mhi.com/information/21112502.html
(4) Capability above 2,700 RT requires two compressors (parallel sort).
(5) COP: coefficient of efficiency as calculated primarily based on Japanese Industrial Requirements (JIS). The upper the COP, the upper the extent of vitality financial savings.
(6) IPLV: built-in half load worth, an indicator of the effectivity of an air-conditioner throughout half load operation. The upper the IPLV, the upper the extent of vitality financial savings.
(7) In contrast with our earlier mannequin (20 years in the past)
(8) ODP: ozone depletion potential, a coefficient expressing the relative quantity of degradation to the ozone layer in comparison with trichlorofluoromethane (CFC-11), a refrigerant beforehand in huge use which has a set ODP of 1.0. The decrease the ODP, the decrease the damaging affect on the ozone layer.
(9) This revised legislation, which took impact on April 1, 2015, stipulates guidelines for the rational use and correct administration of fluorocarbons.
