C-puzzle80
TOKYO, June 30, 2025-(JCN Newswire )- Mitsubishi Heavy Industries Air-Conditioning and Refrigeration Corporation(MHI-AC & R), a Group business of Mitsubishi Heavy Industries, Ltd.(MHI), has actually gotten a Recommendation Award in the Refurbishment Equipment classification of the 42nd Excellent Energy Saving Equipment Awards of the Japan Association of Refrigeration and Air-Conditioning Contractors (JARAC) for its development of energy conserving in updating cooling devices in a superannuated cold-storage storage facility. High honors were provided to the energy cost savings and decrease in carbon emissions attained by the business’s “C-puzzle80,” its most recent refrigeration condensing system utilizing a natural refrigerant of co2 (CO2).
The JARAC Awards were developed to additional promote energy conserving and environmental management of refrigeration and air-conditioning devices by requiring examples of quality and providing awards of acknowledgment as a method of adding to the advancement and expansion of energy-saving innovations, and to increase awareness in associated markets towards energy conserving and environmental management. The brand-new award marks the 5th successive year MHI-AC&& R has actually gotten a JARAC Award.
The cold-storage storage facility for which MHI-AC&& R got this award was built roughly 30 years back by Kanefuji Cold Storage Co., Ltd. of Hokkaido. After carrying out a comprehensive research study of the existing center’s operating status, MHI-AC&& R prepared a repair proposition targeting energy cost savings and decreased carbon emissions. Adoption of the C-puzzle80 led to an 11.3% power conserving and a yearly decrease in CO2 emissions by 31.95 heaps. In addition, the repair work was performed while the existing center stayed in operation, and confirmation was performed upon work conclusion. MHI-AC&& R got praise not simply for its center upgrade however likewise for its steps required to guarantee correct execution and its comprehensive control technique, and so on.
Decrease in Carbon Emissions from Adoption of C-puzzle80
Additional energy conserving with the existing freezer warehouse was challenging owing to the center’s reasonably low particular power intake *. Adoption of the current C-puzzle design, nevertheless, allowed a range of energy conserving techniques, for instance by decreasing devices measurements, which made it possible for more effective operation. In addition, get the cold environment of Hokkaido where the center lies, a style was embraced to promote high-efficiency operation when the outdoors temperature level is low.
A range of developments were likewise made to cut expenses. The numbers of freezers and cooling systems were decreased based on computation of the requisite cooling capability in reflection of the storage facility’s operating conditions. Cooling systems and ducts were enhanced in order to avoid decreases in the weight and volume of saved food or other products triggered by desiccation if they come in contact with cold air, and power to run the center was lowered. To conserve energy, a brand-new control technique was embraced integrating traditional power need control and power standardization control. The brand-new approach immediately changes the variety of freezers and cooling systems in operation and accomplishes steady, energy-saving operation by lessening the variety of systems in operation and avoiding unneeded speed modifications and freezing system begins and stops. These developments not just minimize preliminary expenses however make it possible for cuts in running expenses.
The freshly embraced C-puzzle80 is a design placed as a large-capacity system within the series varying from 10HP to 80HP. The series can accommodate outdoors temperature levels varying from -15 degC to +43 degC, and several designs can be integrated. The C-puzzle80 is perfect for adoption not just in cold-storage and frozen-storage storage facilities and displays, however likewise for multi-purpose cooling. Adoption of all designs in the series has actually likewise been assisted in by removal of the requirement to report their manufacture under the High Pressure Gas Safety Law.
With an eager eye on the future, MHI-AC&& R today is focusing its resources towards accomplishing a carbon-neutral world. Moving forward, the business will attend to client requirements through advancement and adoption of ever more ingenious energy-saving innovations.
* Specific power usage is determined by dividing yearly power use by capability tonnage. It is utilized when examining and comparing power use of cold-storage storage facilities.
