MHI Thermal Systems Receives 2020 Japan Agency for Natural Resources’s Award for MSV2 Series of Heat Pump Chillers

Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems), a part of Mitsubishi Heavy Industries (MHI) Group, has won an Agency for Natural Resources and Energy Commissioner’s Award (Energy Savings Sector) in the “Product & Business Model” category at the 2020 Energy Conservation Grand Prize Awards sponsored by the Energy Conservation Center, Japan (ECCJ). This award was presented for the MSV2 series of air-cooled heat pump chillers(Note1) in recognition of its industry-leading coefficient of performance (COP)(Note2) achieved through a combination of the newly developed “e-3D scroll” compressor and other proprietary technologies. The awards ceremony will be held on January 27.

The MSV2 series comprises four models ranging from 40 to 70 horsepower (hp). These units incorporate the “e-3D scroll” compressor, a more advanced version of the “3D scroll” compressor that compresses the refrigerant from all directions. Modification to the scroll shape, from a step to a slope, has significantly reduced leakage loss, and provided a considerable gain in efficiency at low loads. In addition, the use of a large fan, long bell mouth, and small-diameter hairpin air heat exchanger provide 20% greater power efficiency compared to previous models. Further, this series offers approximately 55% energy reduction compared to absorption-type heating/cooling units.
