TOKYO, Mar 11, 2022 - (JCN Newswire) - Mitsubishi Heavy Industries Air-Conditioning and Refrigeration Corporation (MHI-AC&R), a Group company of Mitsubishi Heavy Industries, Ltd. (MHI), has newly developed a large-capacity brine refrigeration system adopting a nitrogen (N2) refrigerant having both zero ozone depletion potential (ODP)(1) and zero global warming potential (GWP)(2). The new system can accommodate even cryotemperature needs, placing it at the pinnacle of industry offerings(3). The Company has just delivered a unit of the new system to The Honjo Chemical Corporation (Neyagawa, Osaka), a manufacturer of organic chemicals and other products, and further sales in the domestic market will be pursued going forward.
The new system can refrigerate at ultra-low and cryo-temperatures (brine temperature: -45℃ to -100℃) through application of MHI-AC&R's proprietary (patented) air refrigeration cycle technology. The unit also features one of the industry's most compact sizes, enabling easy handling and transport. Its compression expansion machine incorporates MHI Group's accumulated high technologies in gas turbines. In addition to capturing the energy generated during air expansion cooling and using it as drive power, stable operation is achieved through the integration of high technologies such as energy-saving inverter control.

The new refrigeration system contributes significantly to curbing global warming through the adoption of N2, a natural refrigerant having zero environmental impact. In recent years, initiatives to prevent climate change have accelerated in momentum. In Japan, since April 2015, when the Act on Rational Use and Appropriate Management of Fluorocarbons(4) went into effect, the low-temperature refrigeration machine market has been called on to adopt low-GWP refrigerants. Internationally, in tandem with implementation of the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer in January 2019, along with revisions to the Vienna Convention for the Protection of the Ozone Layer, production of chlorofluorocarbon (CFC) substitutes and phased reduction in energy consumption have become mandatory.

Today, because there are few refrigerant options in the ultra-low-temperature refrigeration field, many refrigeration systems continue to use CFC refrigerants. However, demand for CFC-free refrigeration systems is steadily rising in order to mitigate impact on the environment. The refrigerant used in MHI-AC&R's new refrigeration system uses nitrogen, which accounts for approximately 78% of air content, so it is safe both to the environment and to humans. Use of a CFC-free refrigerant also eliminates the inspection procedures mandated under the Act on Rational Use and Appropriate Management of Fluorocarbons, and the new refrigerant is also exempt from the High Pressure Gas Safety Act which regulates the production of high-pressure gases and their consumption, etc. Another benefit is the adoption of magnetic bearings in the system's compression expansion machine, which eliminates the need for lubricating oil and enables a virtually unlimited service life, thereby helping to ease the user's maintenance and operating burdens.

(1) ODP is a coefficient expressing a refrigerant's ozone depletion potential compared to the previously widely used CFC-11 (trichlorofluoromethane), which is assigned a value of 1.0. The lower the ODP value, the smaller is the deleterious impact on the ozone layer.
(2) GWP is a coefficient expressing a refrigerant's global warming potential compared to CO2, which is assigned a value of 1.0. The lower the GWP, the higher is the refrigerant's environmental performance.
(3) Based on MHI-AC&R's in-house survey.
(4) The Act on Rational Use and Proper Management of Fluorocarbons is a totally revised update, carried out in April 2015, to the original Fluorocarbons Recovery and Destruction Law enacted in 2001. Under the revised legislation, commercial refrigeration condensing units and stationary refrigeration units with a refrigeration capacity exceeding 1.5 kilowatt (kW) (approx. 2HP) are required by 2025 to adopt refrigerants with a GWP below 1500 (CO2 =1).

HIROSHIMA, Japan, Mar 9, 2022 - (JCN Newswire) - On March 8, Mazda Motor Europe unveiled its new crossover SUV, the CX-60. It is the first of Mazda's Large Product group models, offering significantly enhanced driving pleasure and environmental and safety performance. This is also the first time the vehicle's full appearance has been made public.
Mazda plans to introduce four models from our Large Product group to the in-high-demand global SUV market by the end of 2023. With both existing and new addition models, Mazda aims to meet diverse market and customer needs with the aim to further grow our business and brand.

Having outstanding environmental and safety performance that meet the strict standards of modern society, the CX-60 is a two-row, mid-sized SUV that allows the driver to enjoy not only everyday driving but also long-distance drives on the expressway. Furthermore, the team at Mazda took on the challenge of taking Kodo-Soul of motion design to new heights, expressing toughness and sophistication in its form utilizing Japanese sense of design that values harmony with nature.

The CX-60 (European specification model) is equipped with e-Skyactiv PHEV, Mazda's first plug-in hybrid system featuring a 2.5-liter in-line four-cylinder gasoline engine and an electric motor. Mazda dealerships in Europe started accepting pre-orders for the model on March 8 and sales are due to begin in summer 2022.

Mazda will begin production of the CX-60 at Hofu Plant No. 2 in Yamaguchi prefecture on March 11, 2022. The Japanese specification CX-60 is due to be introduced in early April.

Mazda aims to become a brand that creates strong bonds with customers by focusing on the pure essence of cars - the joy of driving - and committing ourselves to preserve our beautiful earth, enrich people's lives and make a bountiful society that lifts everybody's spirits.
