Examples of Eco-Products and Hyper Eco-ProductsExamples of Eco-Products and Hyper Eco-Products

Mitsubishi Electric manufactures products that give consideration to the environment in terms of Materials, Energy and Toxicity, or "MET." We have an internal certification program based on proprietary criteria that we use to designate products that help reduce environmental impact as "Eco-Products" and products with an even higher level of environmental performance as "Hyper Eco-Products." Here, we introduce some products that were certified in fiscal 2007.

  • MMaterials: Effective use of resources
  • EEnergy: Efficient use of energy
  • TToxicity: Avoidance of substances that are potentially harmful to the environment

Room Air Conditioner: MSZ-ZW407S

  • Technology to save energy based on usage conditions made possible by the evolution of Move-Eye

  • Factor rating of 2 or above

  • Use of plastic recycled in a closed-cycle

MSZ-ZW407S

This air conditioner prioritizes both comfort and energy efficiency through the use of the "Human-Sensing Move-Eye," a feature that detects where people are located and automatically refines the area that receives air conditioning.

M
  • Closed-cycle recycled plastic from used home appliances is used in the indoor unit cross-flow fan and outdoor unit panel

  • Designed to be easy to clean during use and easy to disassemble when recycling

  • Existing pipes can be reused, which greatly reduces waste

E
  • The Move-Eye feature limits wasteful overcooling and overheating by controlling the perceived temperature; running the unit in automatic mode rather than continuous mode saves energy at a rate of 30%

  • "Human-Sensing Move-Eye" detects people and provides comfortable air conditioning to areas where people are located to improve energy efficiency by another 10%

  • The unit automatically cleans its own filter to prevent deterioration in energy efficiency caused by clogging, without any trouble to the user

T
  • Does not use any substances subject to the EU's RoHS Directive or Japanese Industrial Standards (JIS)'s J-Moss


Residential Heat Pump Water Heaters with Natural Refrigerant: SRT-HP37W1 (representative model)

Factor 2.09: Performance Factor 2.000 X Environmental Impact Factor 1.047
(Factor calculated for SRT-HP46W1 model)
Hyper Eco-Product
Reasons for Certification
  • Received the Chairman's Award at the Energy Conversation Center, Japan's 2006 Energy Conservation Grand Prize Awards

  • Industry leading COP* (as of sales launch in June 2006)
    *Coefficient of performance. A device's outputted energy divided by its inputted energy

SRT-HP37W1

This water heater uses a natural refrigerant that does not damage the ozone layer and features industry-class energy efficiency.

M
  • Fewer parts and greater use of plastic for a weight of 80 kilograms (16% reduction from the previous model)

E
  • Heat pump: High efficiency achieved with a newly developed twist-and-spiral gas cooler with a 4.9 COP rating (previous model was 4.5) and a CO2 compressor that uses Mitsubishi Electric's proprietarily developed joint wrap DC motor

T
  • Hot water tank: Insulating material is foamed polystyrene that does not include hazardous substances; Heat retention improved by 15%.


Package Air Conditioner (Wide Power Cassette Indoor Unit + Zupadan Slim Outdoor Unit): MPLZ-HRP BED Series

Factor 1.73: Performance Factor 1.00 X Environmental Impact Factor 1.733
Hyper Eco-Product
Reasons for Certification
  • Strong market assessment as an air conditioner for truly cold climates

  • High energy efficiency and exceptional piping replacement technology for resource savings

  • Received Honorable Mention at the 2006 Electrical Manufacturers Awards sponsored by the Japan Electrical Manufacturers' Association

MPLZ-HRP BED Series

This heat pump air conditioner maintains its rated heating capacity even when the outdoor air temperature is -15C.

M
  • Existing piping and wiring can be reused, which substantially reduces waste

  • Plastic parts are labeled to make them easy to recycle

E
  • Uses the industry's first flash injection circuit* to improve heat capacity at low temperatures and improve energy efficiency by some 20%

  • Also, Move-Eye 360 prevents temperature irregularity and excessive cooling for additional energy savings of about 30%

T
  • Uses a refrigerant (HFC410A) with an ozone damage coefficient of zero

  • Does not use any substances subject to the EU's RoHS Directive or JIS's J-Moss

*A refrigerant circuit that limits rises in exhaust temperature when the outdoor air temperature is low, and maintains heating capacity with low outdoor air temperatures by compressing refrigerant when it is a two-phase mixture of gas and liquid


Inverter Compressor: PAC80 (for 8.0 kW inverters)

Factor 2.02: Performance Factor 1.00 X Environmental Impact Factor 2.016
Hyper Eco-Product
Reasons for Certification
  • Received the Packaging Technology Logistics Award at the 2006 Japan Packaging Contest held by the Japan Packaging Institute
