New Centrifugal Chiller Model Using New Environment-Friendly Refrigerant Adopted at the Japan National Stadium

Contributing to Measures Against Global Warming

AGC (Headquarters: Tokyo; President & CEO: Takuya Shimamura) together with EBARA REFRIGERATION EQUIPMENT & SYSTEMS (Headquarters: Tokyo; President, Representative Director: Osamu Shono) delivered the “Low GWP high-efficiency centrifugal chiller*1 Model RTBA” (hereafter “the chiller”), which uses the new, environment-friendly refrigerant “AMOLEATM 1224yd” (hereafter “the new refrigerant”) produced by AGC, for air conditioning at the Japan National Stadium. In continuation from this installation, we will proceed with further deployment of this model to various facilities in the future to contribute to the reduction of global warming.

EBARA REFRIGERATION EQUIPMENT & SYSTEMS developed this chiller which uses AGC’s new refrigerant, promoting its installation in various types of facilities including commercial and lodging facilities as well as chemical plants beginning from 2018. The model received the Review Committee’s Special Award at the 21st Ozone Layer Protection and Global Warming Prevention Awards, and its reliable performance and past results have been highly evaluated, leading to its adoption and installation in the Japan National Stadium on this occasion. Since the new refrigerant has excellent compatibility with existing equipment, we are also beginning to provide services for partially modifying past models of chillers and introducing the use of the new refrigerant to them. This eliminates its large initial investment for customers, allowing them to employ this environmental technology as a measure for reducing global warming.

As one grade of the next-generation refrigerant and solvent brand “AMOLEATM” with the concept of “significantly reducing the global warming potential of refrigerants and solvents without affecting the performance they can achieve”, this new refrigerant with a global warming potential which is less than 1/1000 that of past products*2 was successfully developed*3 by AGC, and its sales were started from 2018. It will be possible to contribute greatly to the reduction of climate change by introducing this product for use with various types of chillers.

EBARA REFRIGERATION EQUIPMENT & SYSTEMS and AGC will continue applying their respective technologies and products, making valuable contributions to our customers’ efforts to suppress global warming in the refrigeration, cooling, and air conditioning fields.
