Abstract
Energy-saving in the household refrigerators is attracting attention from consumers because their energy consumption is the largest in the home. Increasing capacity and improving energy-saving performance, which are both major consumer needs, are key technological challenges in the development of more environmentally friendly refrigerators. Energy-saving performance was improved by using vacuum insulation panels to reduce the amount of heat escaping through the insulation walls and by using high efficiency compressors to reduce input energy. Furthermore, Hitachi has achieved both high capacity and energy-savings by using unique energy-saving technologies.
Additionally, with the rise of health consciousness, a “Vacuum Compartment” has been used to successfully preserve food items for longer.
