Mitsubishi Heavy Industries Thermal Systems, Ltd. has started mass production of the ‘KXZ3 Series’ of building-use multi-split air-conditioners for its worldwide markets. The newly added lineup, which adopts the R32 refrigerant, is available in three models: 22.4, 28.0 and 33.5kW. By combining individual units, a maximum of 100.05kW can be achieved to accommodate a wide range of needs. The new series will be launched in the European market this summer, to be followed by successive launches in Australia, New Zealand and Turkey. The KXZ3 Series helps mitigate environmental impacts through the adoption of the R32 refrigerant having a Global Warming Potential (Note 1) of 675, which is roughly one-third the level of the R410A refrigerant (GWP 2090) used in earlier models. The new series also improves energy savings by nearly 18% in Seasonal Energy Efficiency Ratio (Note2), an indicator of an air-conditioner’s energy efficiency. Its efficiency enhancement is owed to…

In 2020, MHI Group identified five material issues in response to the growing need to address the global challenge of climate change. This included providing energy solutions to enable a carbon-neutral world to contribute to solving societal issues and ensuring continued medium and long-term growth.

Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems), a part of Mitsubishi Heavy Industries (MHI) Group, is to add the “Hydrolution PRO” series of air-cooled heat pump chillers (1) to its product lineup for the European market. This series consists of three models with capacities of 50kW/75kW/100kW classes. These models are designed to suit various applications, ranging from space cooling/heating in residential and office buildings to cooling/heating needs in industrial and IT settings. The market launch will initiate with the 50kW-class model in spring 2024, followed by the introduction of other models. With the increasing environmental consciousness in Europe urging for reducing the amount and lowering Global Warming Potential (GWP) of refrigerant used in equipment with refrigerant (2). As one of the countermeasures, MHI Thermal Systems adds the air-cooled heat pump chiller which is the water circulation system to its product lineup. Adoption of the R32 refrigerant (675 GWP),…

Mitsubishi Heavy Industries, Ltd. (MHI) received an “A-minus” rating in the Climate Change Report 2023 published by CDP (headquartered in London, U.K.), a non-profit organisation that maintains a global environmental information disclosure system. This A-minus is the CDP’s second-highest rating and is one rank up from the B ranking MHI received in the previous year. CDP scoring and collected environmental data are publicly available on CDP’s platform and widely referenced by institutional investors and companies. MHI believes this improved rating will enable it to draw broad attention to its progress in addressing climate change in its business activities. Every year since 2002, CDP sends letters to companies on behalf of investors asking those companies to disclose data on their environmental impacts. In 2023, 746 financial institutions (with more than US$136 trillion in invested assets) requested responses to a CDP-prepared questionnaire, and more than 15,000 companies worldwide were asked to provide…

Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems), a Mitsubishi Heavy Industries (MHI) Group company, will launch two new models, the 10HP “HCCV1001C” and 20HP “HCCV2001MC” to its “C-puzzle” series of commercial-use refrigeration condensing units that use the natural refrigerant carbon dioxide (CO2). Both new models, which will be sold in the Japanese market this summer, accommodate MHI Thermal Systems’ proprietary new “M-DIOMAC” system (Note 1). The new units respond to the need to simplify engineering and installation. Models in the C-puzzle series first marketed in 2017 are equipped with MHI Thermal Systems’ proprietary two-stage compressor, a unique configuration of a scroll compressor and a rotary compressor (Note 2). The new M-DIOMAC system provides for a packaged oil management system, which is essential when building a refrigeration system. The packaging simplifies on-site adjustments of the refrigeration units, enabling simpler installation. M-DIOMAC consists of a dedicated system controller and remote…

Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems), a part of Mitsubishi Heavy Industries (MHI) Group, has added a new series, “Hydrolution EZY,” to its lineup of air-to-water (ATW) heat pumps for the European market. This new line includes two models with capacities of 10kW and 14kW, scheduled for release this winter. The Hydrolution EZY series, featuring monobloc design, reflects our commitment to sustainability and contributes to the ongoing development of a decarbonized society in Europe, aligning with our existing eco-friendly split-type units. The series use the eco-friendly R32 refrigerant, just like their split ATW counterparts. They are also quieter during operation and have a broader temperature range. Plus, the integrated water heat exchanger in the outdoor unit simplifies installation compared to the split-type systems, which requires both refrigerant piping and water piping. Innovative engineering has led to an improved anti-vibration technology achieved through material enhancements and other innovations.…
